An uninterruptible power supply (UPS)

2012-01-31T21:04:00.000+08:00

An uninterruptible power supply, also uninterruptible power source, UPS or battery/flywheel backup, is an electrical apparatus that provides emergency power to a load when the input power source, typically mains power, fails. A UPS differs from an auxiliary or emergency power system or standby generator in that it will provide instantaneous or near-instantaneous protection from input power interruptions by means of one or more attached batteries and associated electronic circuitry for low power users, and or by means of diesel generators and flywheels for high power users. The on-battery runtime of most uninterruptible power sources is relatively short—5–15 minutes being typical for smaller units—but sufficient to allow time to bring an auxiliary power source on line, or to properly shut down the protected equipment.

While not limited to protecting any particular type of equipment, a UPS is typically used to protect computers, data centers, telecommunication equipment or other electrical equipment where an unexpected power disruption could cause injuries, fatalities, serious business disruption or data loss. UPS units range in size from units designed to protect a single computer without a video monitor (around 200 VA rating) to large units powering entire data centers, buildings, or even cities.

Hydro Jet Blasting

2011-12-24T07:36:00.002+08:00

Hydro jetting and Hydro blaster equipment is used to direct high pressure streams of water against a surface to clean or cut the material. The steams of water released by hydro jetting and hydro blasting equipment can exceed 10,000 psi. hydro jetting and hydro blaster equipment is used for cleaning or demolition of products made of metal, wood, concrete, stone, plastic, glass or other building materials.

Specific components within a hydro jetting or hydro blaster equipment system include abrasive injectors, pressure generators, blast cabinets or booths, water guns, and water tanks. Plunger-type intensifier pumps are commonly used to generate high pressure water for water jet cutting, wet or water abrasive blasting and non-abrasive pressure washing or rinsing. Crankshaft driven plunger pumps are also used for pressure generation.

Usually crankshaft driven plunger pumps may be more efficient in electrical energy costs compared to intensifiers, but at high pressures (>20,00 psi, 137 bar) seals must be periodically replaced. Crankshaft driven plunger pumps also provide a virtually ripple free pressure source in comparison to intensifiers. An accumulator may be required to smooth out pressure fluctuations if an intensifier pump is used. In air based blast or jet systems, air compressors are typically used to generate pressure which add heavy running cost.

Water guns or lances are the apparatus within hydro jetting and hydro blaster equipment that directs the stream of water through a nozzle and at the appropriate region of the work piece.

The water tank or hopper is used for storage of water, cleaning agents, blasting media or abrasive-water slurry mixtures.

Sheet Metal

2011-12-12T20:47:00.001+08:00

Sheet metal is simply metal formed into thin and flat pieces. It is one of the fundamental forms used in metalworking, and can be cut and bent into a variety of different shapes. Countless everyday objects are constructed of the material. Thicknesses can vary significantly, although extremely thin thicknesses are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate.

Sheet metal is available in flat pieces or as a coiled strip. The coils are formed by running a continuous sheet of metal through a roll slitter.

The thickness of the sheet metal is called its gauge. The gauge of sheet metal ranges from 30 gauge to about 8 gauge. The larger the gauge number, the thinner the metal.

There are many different metals that can be made into sheet metal, such as aluminum, brass, copper, steel, tin, nickel and titanium. For decorative uses, important sheet metals include silver, gold, and platinum (platinum sheet metal is also utilized as a catalyst.)

Sheet metal has applications in car bodies, airplane wings, medical tables, roofs for buildings and many other things. Sheet metal of iron and other materials with high magnetic permeability, also known as laminated steel cores, has applications in transformers and electric machines. Historically, an important use of sheet metal was in plate armor worn by cavalry, and sheet metal continues to have many decorative uses, including in horse tack.

Commutator Electric

2011-11-11T15:53:00.000+08:00

A commutator is a rotary electrical switch in certain types of electric motors or electrical generators that periodically reverses the current direction between the rotor and the external circuit. In a motor, it applies power to the best location on the rotor, and in a generator, picks off power similarly. As a switch, it has exceptionally long life, considering the number of circuit makes and breaks that occur in normal operation.

A commutator is a common feature of direct current rotating machines. By reversing the current direction in the moving coil of a motor's armature, a steady rotating force (torque) is produced. Similarly, in a generator, reversing of the coil's connection to the external circuit provides unidirectional—direct—current to the external circuit. The first commutator-type direct current machine was built by Hippolyte Pixii in 1832, based on a suggestion by André-Marie Ampère.

What does CCCW stand for? CCCW stand for Closed Circuit Cooling Water. The reason in a power plant that have CCCW is for heat rejection system, which extracts waste heat to the atmosphere though the cooling of a water stream to a lower temperature.

Load Rejection Tests

2011-10-25T00:19:00.000+08:00

Load Rejection Tests

A full series of load rejection tests should be performed and the results documented. These tests should include all conditions that can occur during the full range of operation. The data from these tests are needed to determine the maximum and minimum operating pressures and unit speeds.

Based upon data obtained from the hydraulic transient analysis, stop nuts on the governor main distributing valve servomotor are then set to limit the full rate opening and closing times of the wicket gates with the turbines unwatered, the governor in "main valve," and the shutdown solenoids blocked in the running position. Rapid operation of the gate limit between 0 and 100 percent will then cause the gates to operate at maximum rate. Experience has indicated that full rate closure under actual operating conditions tends to be about 10 percent faster than the unwatered setting.

To set the gate timing accurately, the stopwatch has been replaced with a position transducer attached to the servomotor and a strip chart recorder. Minimum test equipment for the load rejection tests, if required to verify the computer model, includes:

Results of the hydraulic transient study to allow safe initial adjustments.
Pressure transducers on the penstock and/or spiral case.
A tachometer to measure unit overspeed.
A position transducer on the wicket gates.
A voltage transducer to measure the generator voltage transient.
A strip chart recorder with at least 4 channels.

Electric Motor

2011-10-15T15:50:00.001+08:00

An electric motor converts electrical energy into mechanical energy.

Most electric motors operate through the interaction of magnetic fields and current-carrying conductors to generate force. The reverse process, producing electrical energy from mechanical energy, is done by generators such as an alternator or a dynamo; some electric motors can also be used as generators, for example, a traction motor on a vehicle may perfom both tasks. . Electric motors and generators are commonly referred to as electric machines.

Electric motors are found in applications as diverse as industrial fans, blowers and pumps, machine tools, household appliances, power tools, and disk drives. They may be powered by direct current (e.g., a battery powered portable device or motor vehicle), or by alternating current from a central electrical distribution grid or inverter. The smallest motors may be found in electric wristwatches. Medium-size motors of highly standardized dimensions and characteristics provide convenient mechanical power for industrial uses. The very largest electric motors are used for propulsion of ships, pipeline compressors, and water pumps with ratings in the millions of watts. Electric motors may be classified by the source of electric power, by their internal construction, by their application, or by the type of motion they give.

The physical principle of production of mechanical force by the interactions of an electric current and a magnetic field was known as early as 1821. Electric motors of increasing efficiency were constructed throughout the 19th century, but commercial exploitation of electric motors on a large scale required efficient electrical generators and electrical distribution networks.

Some devices convert electricity into motion but do not generate usable mechanical power as a primary objective and so are not generally referred to as electric motors. For example, magnetic solenoids and loudspeakers are usually described as actuators and transducers, respectively, instead of motors. Some electric motors are used to produce torque or force.

Generator Stator winding

Stator wedges

Stator core

Thin Layer Electrical Metal Steel

General info on stator core

The stator core has an internal diameter of 4630 mm and a length of 2250 mm. It is
built up from segmental laminations punched from high grade, cold reduced, electrical
sheet steel, which are held in the frame by dovetailed keybars. The laminations are
divided into 59 layers (packets) formed by narrow steel spacers which provide
ventilating ducts leading from the stator bore to the periphery of the core.

Stator winding

The stator winding is of the double layer lap type, each layer comprising 64
conductors (32 deep by 2 wide) and each conductor being 2.24 mm x 5.8 mm glass
laminate covered copper strip. The conductors are transposed within the slot length
to inhibit circulating currents between

Stator wedge plate layers.

The two layers (bars) are wound and packed into the open core slots. The top and
bottom bars are spaced apart by a separator and retained in the slots by wedges

Dry ice blasting on the stator

2011-08-23T06:24:00.002+08:00

Dry ice blasting on the stator

Dry ice blasting is a form of abrasive blasting, where dry ice, the solid form of carbon dioxide, is accelerated in a pressurized air stream and directed at a surface in order to clean it. Dry ice blasting leaves no chemical residue as dry ice sublimates at room temperature.

Objective: To remove dirt and unwanted contaminants on the stator core. This process also removes the varnish stain on the stator core.

Working principles:

Dry ice blasting machine

Dry ice blasting is a form of abrasive blasting, where dry ice, the solid form of carbon dioxide, is accelerated in a pressurized air stream and directed at a surface in order to clean it. Dry ice blasting leaves no chemical residue as dry ice sublimates at room temperature.

Dry ice blasting involves propelling pellets at extremely high speeds. The actual dry ice pellets are quite soft, and very less dense. Upon impact, the pellet sublimates almost immediately, transferring minimal kinetic energy to the surface on impact and producing minimal abrasion.

Dry ice blasting - air compressor

The sublimation process absorbs a large volume of heat from the surface, producing shear stresses due to thermal shock. This is assumed to improve cleaning as the top layer of dirt or contaminant is expected to transfer more heat than the underlying substrate and flake off more easily. The efficiency and effectiveness of this process depends on the thermal conductivity of the substrate and contaminant.

Mahnehelic Gauge
What Is A Magnehelic Gauge

A magnehelic pressure gauge is a device, similar to a manometer, used to measure positive, negative and differential pressures. These gauges are often used in the HVAC industry to measure pressure drop across air filters to determine when it is time for them to be changed.

Although magnehelic gauges are resistant to shock and vibration, they are extremely sensitive and accurate. Calibration is very easy due to the zero calibration screw located on the plastic cover. Although Dwyer makes gauges in about thirty different pressure ranges, the most common ranges are 0 to 0.5 in, w,g. (25 Pa), 0 to 1.0 in. w.g. (250 Pa), and 0 to 5.0 in. w. g. (1250 Pa). They consist of a die cast aluminum case and bezel with an acrylic cover. Magnehelic gauge accuracy is typically + or – 2%.

Stator

2011-08-10T15:35:00.000+08:00

The stator is the stationary part of a rotor system, found in an electric generator, electric motor and biological rotors.

Depending on the configuration of a spinning electromotive device the stator may act as the field magnet, interacting with the armature to create motion, or it may act as the armature, receiving its influence from moving field coils on the rotor.

The first DC generators (known as dynamos) and DC motors put the field coils on the stator, and the power generation or motive reaction coils on the rotor. This was necessary because a continuously moving power switch known as the commutator is needed to keep the field correctly aligned across the spinning rotor. The commutator must become larger and more robust as the current increases.

The stator of these devices may be either a permanent magnet or an electromagnet. Where the stator is an electromagnet, the coil which energizes it is known as the field coil or field winding.

An AC alternator is able to produce power across multiple high-current power generation coils connected in parallel, eliminating the need for the commutator. Placing the field coils on the rotor allows for an inexpensive slip ring mechanism to transfer high-voltage, low current power to the rotating field coil.

It consists of a steel frame enclosing a hollow cylindrical core (made up of laminations of silicon steel). The laminations are to reduce hysteresis and eddy current losses.

Strain Gauge

2011-07-27T20:38:00.000+08:00

Typical foil strain gauge. The gauge is far more sensitive to strain in the vertical direction than in the horizontal direction. The markings outside the active area help to align the gauge during installation.

A strain gauge is a device used to measure the strain of an object. Invented by Edward E. Simmons and Arthur C. Ruge in 1938, the most common type of strain gauge consists of an insulating flexible backing which supports a metallic foil pattern. The gauge is attached to the object by a suitable adhesive, such as cyanoacrylate.As the object is deformed, the foil is deformed, causing its electrical resistance to change. This resistance change, usually measured using a Wheatstone bridge, is related to the strain by the quantity known as the gauge factor.

Physical operation

A strain gauge takes advantage of the physical property of electrical conductance and its dependence on not merely the electrical conductivity of a conductor, which is a property of its material, but also the conductor's geometry. When an electrical conductor is stretched within the limits of its elasticity such that it does not break or permanently deform, it will become narrower and longer, changes that increase its electrical resistance end-to-end. Conversely, when a conductor is compressed such that it does not buckle, it will broaden and shorten, changes that decrease its electrical resistance end-to-end. From the measured electrical resistance of the strain gauge, the amount of applied stress may be inferred.

A typical strain gauge arranges a long, thin conductive strip in a zig-zag pattern of parallel lines such that a small amount of stress in the direction of the orientation of the parallel lines results in a multiplicatively larger strain over the effective length of the conductor—and hence a multiplicatively larger change in resistance—than would be observed with a single straight-line conductive wire. Strain gauges measure only local deformations and can be manufactured small enough to allow a "finite element" like analysis of the stresses to which the specimen is subject. This can be positively used in fatigue studies of materials.

Rotor

2011-07-22T15:42:00.002+08:00

The rotor is the non-stationary part of a rotary electric motor, electric generator or alternator, which rotates because the wires and magnetic field of the motor are arranged so that a torque is developed about the rotor's axis. In some designs, the rotor can act to serve as the motor's armature, across which the input voltage is supplied. The stationary part of an electric motor is the stator. A common problem is called cogging torque.

Introduction to Pressure Transducers

2011-07-22T07:44:00.000+08:00

Pressure Transducer

What is a pressure transducer? A pressure transducer is a transducer that converts pressure into an analog electrical signal. Although there are various types of pressure transducers, one of the most common is the strain-gage base transducer.

The conversion of pressure into an electrical signal is achieved by the physical deformation of strain gages which are bonded into the diaphragm of the pressure transducer and wired into a wheatstone bridge configuration. Pressure applied to the pressure transducer produces a deflection of the diaphragm which introduces strain to the gages. The strain will produce an electrical resistance change proportional to the pressure.

Electric Generator

2011-07-15T20:01:00.000+08:00

In electricity generation, an electric generator is a device that converts mechanical energy to electrical energy. A generator forces electrons in the windings to flow through the external electrical circuit. It is somewhat analogous to a water pump, which creates a flow of water but does not create the water inside. The source of mechanical energy may be a reciprocating or turbine steam engine, water falling through a turbine or waterwheel, an internal combustion engine, a wind turbine, a hand crank, compressed air or any other source of mechanical energy.

The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors and generators have many similarities. In fact many motors can be mechanically driven to generate electricity, and very frequently make acceptable generators.

System 1® Software

System 1 Software
Condition Monitoring and Diagnostics Software Platform

Widely used across many industries, System 1 enables plant personnel to quickly identify important events, evaluate the situation, and respond, leading to increased equipment availability, reliability, and reduced maintenance costs. System 1 is GE Energy’s patented software platform for real-time optimization of equipment and selected processes, condition monitoring, and event diagnostics. Similar in concept to a process control system which allows users to understand, diagnose, and control their process conditions in real time, the System 1 platform provides this capability for the assets that drive your process.

Benefits

Increased safety
A single “miss” on safety or the environment can be disastrous. Proactive capabilities mean fewer, less severe mechanical failures that could impact people and the environment.

Improved reliability and availability
Healthy assets are assets you can depend on when they are needed. Problems can be identified and dealt with early in the progression of symptoms – before they translate to expensive downtime.

Optimized maintenance costs
System 1 helps you plan maintenance by allowing you to base decisions on actual condition – so you can fix only what really needs fixing and address problems when they are small and less expensive.

Lower energy costs
Energy costs are often a plant’s single largest operating expense. System 1 helps assess and correct the conditions that waste energy.

Fewer forced outages, less lost production
Even the most expensive repair and maintenance costs are often eclipsed by the enormous costs of lost or reduced production. System 1 can generally save one or more days of lost production due to mechanical failures in the first year alone, often paying for the entire system in a single “event.”

Increased thermal efficiency/optimized heat rate
System 1 can provide the information you need to understand and correct degradations in these important parameters, and optimize the balance between energy costs, maintenance costs, and production revenues – often translating to significant financial benefits.

Increased employee productivity
In today’s “lean” environment, people are already spread too thin. Instead of using people to hunt for problems, System 1 allows your people to work on identified problems, armed with relevant information on the identified symptoms and root causes.

Move data, not people
With its remote access capabilities, System 1 can reduce travel costs, minimizing the need for people to move from place to place collecting data, and leaving them extra time for completing more meaningful activities. Data can not only be collected remotely, it can be analyzed remotely, allowing users to more easily manage assets from various locations – whether across an entire globally dispersed enterprise, or simply another process unit elsewhere in the plant.

Easier collaboration
Key information can easily be shared between all relevant parties – employees, contractors, suppliers, or consultants – in real time. Enhanced collaboration means more relevant expertise can be applied to problems for faster, better resolution.

Faster response, reduced human variance
Abnormal situations can be stressful, making it difficult for people to respond both quickly and properly. System 1 delivers Actionable Information* advisories that tell your people exactly how to respond to events – you decide in advance and embed these details right in the software. Instead of deciding how to respond, personnel can respond with predetermined actions – and at the speed your business demands.

Features

Sophisticated alarm management
System 1 enables true “management by exception” with its sophisticated alarm handling capabilities for the entire enterprise, ensuring that only relevant events and alarms are delivered to your operations and other personnel. No more overwhelming alarm lists, nuisance alarms, and cryptic messaging with insufficient details – you control the level of attention given to each event, the type of notification, the people notified, and all other details.

Configurable data acquisition and storage resolution
Data capture can be individually configurable for each point and can be triggered by an event, by the state of another variable, by predetermined time intervals, or any combination of these parameters. “Dead band” capabilities ensure that data which is not changing within user-configurable limits for each point can be suppressed from storage – helping keep database sizes compact without missing important information and events or disrupting trend resolution.

Powerful analytic and diagnostic capabilities
Data can be manipulated and presented using an extensive library of tools and functions – data can even be exported to spreadsheets and imported again for special calculations. Advanced plot management tools – such as plot grouping – make it easy to create, save, access, and duplicate plots of common interest. Users can quickly see what happened before and after an event using intuitive “zoom in/zoom out” capabilities on plot time ranges.

Support for Virtual Private Network (VPN) technologies
VPN technologies are being increasingly used by many of our customers for accessing their corporate networks via a public Internet connection – without compromising security. System 1 fully supports this technology, providing the most convenient remote access capabilities we’ve ever been able to offer.

Fully customizable displays
Just as you configure and personalize your Windows® desktop, System 1 users can individually configure their display capabilities, ensuring that only those assets and portions of the enterprise relevant to them are presented.

Enhanced IT management and support capabilities
System 1* has been designed for highly secure and robust operation without the need for extensive support from your company’s Information Technology Department, while still providing powerful tools and capabilities for them to centrally manage the PCs across your enterprise.

One database
System 1 integrates numerous data sources into a single system, reducing the need for learning and maintaining multiple systems. Portable data collectors, online wired and wireless continuous and intermittent measurement systems, manually entered data and notes, and many other data sources – all are now brought together in a single system.

Highly scalable
Your System 1 implementation can start small and build through an architecture and pricing structure that has been deliberately designed for scalability and affordability. Pay for what you need today, add what you need tomorrow.

One user interface
System 1 accepts data from multiple sources but eliminates the need for learning and navigating multiple user interface environments – providing a consistent, intuitive look and feel for viewing data and information. When you need access to external systems and user interfaces, its built-in DocuView* features provide consistent, easy-to-use access to supplementary programs, data, drawings, documents, web pages, and any other information that you can link to from your computer.

Root cause analysis
System 1 provides unrivaled root cause diagnostic capabilities by allowing users to “drill down” and examine the sequence of events leading up to a problem, analyze the data using powerful graphical and tabular presentation formats, and then document this learning, either by posting notes in the database or by generating new rules, capable of automatically analyzing future events with the same root cause.

Ball Pressure Gauge

Tachikara GAUGE Ball Pressure Gauge. Price is around $12.95

Atmospheric pressure

2011-06-30T07:13:00.000+08:00

Atmospheric pressure is the force per unit area exerted against a surface by the weight of air above that surface in the Earth's atmosphere. In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. Low pressure areas have less atmospheric mass above their location, whereas high pressure areas have more atmospheric mass above their location.

Similarly, as elevation increases there is less overlying atmospheric mass, so that pressure decreases with increasing elevation. A column of air one square centimetre in cross-section, measured from sea level to the top of the atmosphere, has a mass of about a kilogram and a weight of 63N (and a column one inch in cross-section would weigh about 14 lb).

TNB unit wins job in Pakistan

2011-06-21T07:12:00.000+08:00

It seals RM43mil operation and maintenance agreement with Laraib Energy

KUALA LUMPUR: Tenaga Nasional Bhd's (TNB) unit TNB Repair and Maintenance Sdn Bhd (TNB Remaco) has secured an operation and maintenance agreement worth US$14.1mil (RM43mil) from Pakistan's Laraib Energy Ltd.

TNB Remaco will be the operator of the 84MW New Bong Escape Hydroelectric Power Complex on the Jhelum River in Azad Jammu and Kashmir.

“Under the contract, TNB Remaco will provide services for an initial period of five years with an option of extending for another seven years,” president/chief executive officer Datuk Seri Che Khalib Mohamad Noh said at the signing ceremony between TNB Remaco and Laraib Energy yesterday.

Khalib who is also the chairman of TNB Remaco said the 15-month mobilisation period was expected to commence in August.
Technical tie-up: Khalib (left) exchanging documents with Harris. With them are (from left) Energy, Water and Communications MInistry deputy secretary-general Badaruddin Mahyuddin and Pakistani Deputy High Commissioner Imtiaz A. Kazi. - Starpic by Rohaizat bin Md Darus

TNB Remaco will provide technical personnel and skilled expertise to perform daily operations as well as routine maintenance of the complex.

“This new agreement marks TNB Remaco's second collaboration with HUB Power Co (a major shareholder of Laraib Energy). The first being the operation and maintenance agreement for the 213.6MW diesel and co-generation power plant in Punjab, Pakistan,” said Khalib.

He said the agreement would further augment TNB Remaco's reputation as a one-stop service provider for power-related works and also identified TNB Remaco's repair centre as a regional repair hub, in line with TNB's aim to be a global brand.

Laraib Energy's chairman and Hub Power Co's chief executive officer Vince Harris said the company had invested some US$235mil on the hydroelectric power plant and it was well advanced in commercialisation.

He described the 84MW hydroelectric plant as a “major infrastructure project.”

Harris said TNB Remaco won the job as the group was confident with its capability and expertise.

Khalib said the company was “looking” at various opportunities for maintenance job including in Indonesia and Brunei.

He said TNB Remaco's strategy was to provide services and not buying assets.

TNB Remaco managing director Nor Azman Mufti said the group aimed to increase its overseas' revenue contribution to 40% from 10% currently.

Khalib said TNB had been working closely with the Government on the negotiation with independent power purchasers (IPP). “We look forward for the positive outcome of the negotiation with IPPs.”

He, however, declined to reveal details of the negotiations. “The details are best answered by the Government.”

Meanwhile, Khalib said TNB would not be extending its power purchase with PowerSeraya Ltd, a unit of YTL Power International Bhd when it expired on June 15.

“At the moment there's no need to extend it. We will only know if we need to purchase from Singapore at the next curtailment at the end of the month whereby Petroliam Nasional Bhd-owned gas production platform will undergo maintenance work,” he said.

Khalib said the purchase represented only 1% of total demand. He explained that TNB was buying power across the border for security reason and it was normal for any utility company to make such purchases.

“We have managed to pull through in the past two major curtailment. We're confident to pull it through this time as well,” he said, adding that there was no shortage of power supply and it had an excess capacity of 40% currently.

Plate heat exchanger

2011-05-24T19:29:00.000+08:00

A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids. This has a major advantage over a conventional heat exchanger in that the fluids are exposed to a much larger surface area because the fluids spread out over the plates. This facilitates the transfer of heat, and greatly increases the speed of the temperature change. Plate heat exchangers are now common and very small brazed versions are used in the hot-water sections of millions of combination boilers. The high heat transfer efficiency for such a small physical size has increased the domestic hot water (DHW) flowrate of combination boilers. The small plate heat exchanger has made a great impact in domestic heating and hot-water. Larger commercial versions use gaskets between the plates, smaller version tend to be brazed.

The concept behind a heat exchanger is the use of pipes or other containment vessels to heat or cool one fluid by transferring heat between it and another fluid. In most cases, the exchanger consists of a coiled pipe containing one fluid that passes through a chamber containing another fluid. The walls of the pipe are usually made of metal, or another substance with a high thermal conductivity, to facilitate the interchange, whereas the outer casing of the larger chamber is made of a plastic or coated with thermal insulation, to discourage heat from escaping from the exchanger.

Advantages and disadvantages of plate heat exchangers

2011-04-24T19:33:00.000+08:00

Advantages

Compactness- The units in a plate heat exchanger occupy less floor space and floor loading by having a large surface area that is formed from a small volume. This in turn produces a high overall heat transfer coefficient due to the heat transfer associated with the narrow passages and corrugated surfaces.
Flexibility- Changes can be made to heat exchanger performance by utilizing a wide range of fluids and conditions that can be modified to adapt to the various design specifications. These specifications can be matched with different plate corrugations.
Low Fabrication Costs- Welded plates are relatively more expensive than pressed plates. Plate heat exchangers are made from pressed plates, which allow greater resistance to corrosion and chemical reactions.
Ease of Cleaning- The heat exchanger can be easily dismantled for inspection and cleaning (especially in food processing) and the plates are also easily replaceable as they can be removed and replaced individually.
Temperature Control- The plate heat exchanger can operate with relatively small temperature differences. This is an advantage when high temperatures must be avoided. Local overheating and possibility of stagnant zones can also be reduced by the form of the flow passage.

Disadvantages

The main weakness of the plate and frame heat exchanger is the necessity for the long gaskets which holds the plates together. Although these gaskets are seen as drawback, plate-and-frame heat exchangers have been successfully run at high temperatures and pressures.
There is a potential for leakage. The leaks that occur are sent to the atmosphere and not between process streams.
The pressure drop that occurs through a plate heat exchanger is relatively high and the running costs and capital of the pumping system should be considered.
When loss of containment or loss of pressure occurs, it can take a long time to clean and reinitialise this type of exchanger as hundreds of plates are common in larger builds.
The narrow spacing between plates can become blocked by particulate contaminants in the fluid, for example oxide and sludge particles found in central heating systems.
For the reason above most manufacturers will only guarantee their units for 12 months, furthermore replacement plate and gasket sets can be as much as the plate to buy initially.

Simple solar system

Solar system

Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation, along with secondary solar-powered resources such as wind and wave power, hydroelectricity and biomass, account for most of the available renewable energy on earth. Only a minuscule fraction of the available solar energy is used.

Solar powered electrical generation relies on heat engines and photovoltaics. Solar energy's uses are limited only by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, daylighting, solar hot water, solar cooking, and high temperature process heat for industrial purposes.To harvest the solar energy, the most common way is to use solar panels.

Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.

Micro hydro: how it works

2011-04-09T22:15:00.001+08:00

Micro hydro uses diverted river water to local produce up to 100 KW of power. Very useful in water rich areas where access to other energy sources is difficult. Find out how it works in this minute long silent animation.

The ecological impact of small-scale hydro is minimal; but the low-level environmental effects must be taken into consideration before construction begins. Stream water will be diverted away from part of the stream, so proper caution must be exercised to ensure there is no damaging impact on the local ecology.

TNB to build gas-fired power plant in Sabah

2011-03-23T20:28:00.001+08:00

SINGAPORE: Malaysia's national power producer Tenaga Nasional Bhd (TNB) (5347) plans to build a 300-megawatt gas-fired power plant in Sabah, chief executive Officer Datuk Seri Che Khalib Mohamad Noh said yesterday.

The plan to build a gas-based plant comes after Malaysia's federal and Sabah state governments scrapped a plan to build a coal-fired power plant.

Che Khalib said TNB has received in-principle approval to build the plant.

"It will be a gas-fired plant to replace the coal-based one that was being planned. We are looking to do it either through piped gas of LNG."
The company is currently assessing whether piping in the gas from another part of the state or importing it in its chilled form as liquefied natural gas was the best option economically, he added.

TNB said he expects to mitigate the impact of rising coal prices on the company's bottom line by securing long-term supply contracts with mines in Australia, Indonesia and South Africa.

He ruled out taking ownership in any of them. "We don't believe in owning mines," Che Khalib said.

TNB had in January warned of greater pressure on its margins for the rest of the year on skyrocketing price of coal.

In a worst case scenario, TNB's 2011 earnings would be 20 per cent lower than 2010, although Che Khalib said he expected coal prices to moderate after February.

About 40 per cent of the company's power supply is coal-fired.

Despite growing imports of LNG, Che Khalib expects Malaysia to remain a next exporter of the super-cooled gas for the next 20 years, he said. - Reuters

If the steam coming out of the towers was radioactive then all people around the tower would die. Steam can 't be radioactive unless mixed with radiation. Which would not happen in a nuclear power plant.

The energy is created when the heat coming from the nuclear reaction heats up water and directs it towards a turbine. This turbine turns and generates electricity to power things.

TNB awards RM2.15bil jobs for Ulu Jelai project

2011-03-05T09:00:00.000+08:00

PETALING JAYA: Tenaga Nasional Bhd (TNB) has signed two agreements worth some RM2.15bil for its Ulu Jelai hydroelectric project.

The company said the first agreement was with SMEC International Pty Ltd and SMEC (M) Sdn Bhd consortium, which would provide detailed engineering design for the main civil works, engineering design review for electrical and mechanical works, project management and site supervision.

The contract value was A$22.1mil and RM31.1mil, which was equivalent to RM99.6mil at the prevailing exchange rates, it told Bursa Malaysia yesterday.

The second agreement is with Tindakan Mewah Sdn Bhd and Salini Costruttori SpA consortium. Under this contract, the consortium will be responsible for the main civil, electrical and mechanical works.

The main civil works consist of the construction of a dam, two water-transfer tunnels and an underground power house.

TNB said the electrical and mechanical works involved the design, manufacture, erection, testing and commissioning of two power generation plant, each with a capacity of 186MW, and the associated electrical and mechanical equipment.

It said the value of the second contract was 307 million euros and RM818.1mil, which was equivalent to RM2.05bil at the prevailing exchange rates.

The company said the contract period for the development of the Ulu Jelai hydroelectric project was five years, during which the payment to the contractors would be made in accordance with the progress.

The project cost will potentially result in an increase in TNB's net assets by about 7.1%.

TNB said the project was expected to be completed by July 2016.

Government Likely To Decide On Concessionaire For Second Coal-Fired Power Plant In June

2011-03-04T08:28:00.000+08:00

KUALA LUMPUR, Feb 24 (Bernama) -- The government is likely to decide on the concessionaire for the second 1,000-megawatt (MW) coal-fired power plant in June this year, says Energy Commission chairman Tan Sri Dr Ahmad Tajuddin Ali.

He said the commission has issued the request for proposals from MMC Corp Bhd's unit, Malakoff Corp Bhd, and Jimah Energy Ventures Sdn Bhd with regard to the plant.

The sites for the plant would either be at Tanjung Bin in Johor, owned by MMC Corp Bhd or Jimah in Negeri Sembilan owned by Jimah Energy Ventures.

"We gave them until April this year to submit their proposals and we will do the analysis to decide on which one (the site)," Ahmad Tajuddin told reporters after a luncheon talk on alternative energy, organised by the Federation of Public Listed Companies Bhd, here Thursday.

Ahmad Tajuddin said the new plant was needed because the initial 1,600MW power to be generated by the Bakun hydroelectric station in Sarawak would not come to Peninsular Malaysia as planned in 2015.

"The immediate plan is to make sure that the gap left by Bakun is replaced. These coal-fired power plants would fill the gap," he said.

He said the first 1,000MW coal-fired power plant has been awarded to Tenaga Nasional Bhd (TNB), adding that TNB was in the final stages of making deciding on the engineering, procurement and construction contractor.

"The first plant is expected to commence operation in the first quarter of 2015 while the second plant will be in the first quarter of 2016.

"A 1,000MW coal plant will cost between RM3 billion and RM4 billion," he said.

Ahmad Tajuddin said new power plants would be built as the electricity demand was expected to grow by an average 3.4 per cent from 2011 to 2020.

"With growing energy demand and declining fossil fuel reserves, the country is looking to enhance and encourage the usage of renewable energy," he said.

He said the government was taking initiatives to secure future energy supply, such as diversifying sources of fossil fuel supply by seeking a more balanced generation fuel mix.

"Other initiatives are strengthening and expanding fuel and electricity supply infrastructures towards regional interconnection, exploring and building capacity for the nuclear option and promoting renewable energy resources via through enhanced fiscal incentives, grants and subsidies," he said.

He said the country aimed to achieve the target of six per cent of the electricity generated from renewable energy in 2015 from less than one per cent now.

Thermography

2011-02-21T22:18:00.001+08:00

Infrared thermography, thermal imaging, and thermal video are examples of infrared imaging science. Thermal imaging cameras detect radiation in the infrared range of the electromagnetic spectrum (roughly 9000–14,000 nanometers or 9–14 µm) and produce images of that radiation, called thermograms. Since infrared radiation is emitted by all objects near room temperature, according to the black body radiation law, thermography makes it possible to see one's environment with or without visible illumination. The amount of radiation emitted by an object increases with temperature; therefore, thermography allows one to see variations in temperature. When viewed through a thermal imaging camera, warm objects stand out well against cooler backgrounds; humans and other warm-blooded animals become easily visible against the environment, day or night. As a result, thermography is particularly useful to military and other users of surveillance cameras.

Thermography has a long history, although its use has increased dramatically with the commercial and industrial applications of the past fifty years. Government and airport personnel used thermography to detect suspected swine flu cases during the 2009 pandemic.[1] Firefighters use thermography to see through smoke, to find persons, and to localize the base of a fire. Maintenance technicians use thermography to locate overheating joints and sections of power lines, which are a tell-tale sign of impending failure. Building construction technicians can see thermal signatures that indicate heat leaks in faulty thermal insulation and can use the results to improve the efficiency of heating and air-conditioning units. Some physiological changes in human beings and other warm-blooded animals can also be monitored with thermal imaging during clinical diagnostics.

The appearance and operation of a modern thermographic camera is often similar to a camcorder. Often the live thermogram reveals temperature variations so clearly that a photograph is not necessary for analysis. A recording module is therefore not always built-in.

The CCD and CMOS sensors used for visible light cameras are sensitive only to the nonthermal part of the infrared spectrum called near-infrared (NIR). Thermal imaging cameras use specialized focal plane arrays (FPAs) that respond to longer wavelengths (mid- and long-wavelength infrared). The most common types are InSb, InGaAs, HgCdTe and QWIP FPA. The newest technologies use low-cost, uncooled microbolometers as FPA sensors. Their resolution is considerably lower than that of optical cameras, mostly 160x120 or 320x240 pixels, up to 640x512 for the most expensive models. Thermal imaging cameras are much more expensive than their visible-spectrum counterparts, and higher-end models are often export-restricted due to the military uses for this technology. Older bolometers or more sensitive models such as InSb require cryogenic cooling, usually by a miniature Stirling cycle refrigerator or liquid nitrogen.

Malaysia drops 300MW coal-fired Sabah power plant project

2011-02-18T19:59:00.000+08:00

KOTA KINABALU, Feb 17 (Bernama) -- The more than 3.3 million people in Sabah can now heave a big sigh of relief as the government has made a final decision not to build coal-fired power plants in the state.

The long-awaited decision proved beyond doubt that the government subscribed to the 1Malaysia concept which prioritised the people's interests.

In delivering the good news yesterday, Chief Minister Datuk Seri Musa Aman said the Barisan Nasional (BN) government under the leadership of Prime Minister Datuk Seri Najib Tun Razak was "a government that always listens to the voice and feels the pulse of the people".

The timely announcement was made all the more sweet because the Federal and state governments had also agreed to use liquefied natural gas (LNG) to generate power instead of coal-fired energy.

"This is a perfect new year gift for the people of Sabah. This decision is correct and it reflects the BN's sensitivity to the grouses of the people.

"It means that our Chief Minister is listening and we in Parti Bersatu Sabah (PBS) certainly welcome this decision," said PBS secretary-general Datuk Henrynus Amin to Bernama, here Thursday.

For this, he congratulated Musa on his bold decision to cancel out the proposed coal plant project in Lahad Datu for the good of the people.

"We believe that the state government must have taken into account all factors before making the decision," he said.

Local political analyst Edward Kandok perceived this development as another "plus point" for the BN to further strengthen its position in Sabah, dubbed as a "fixed deposit" for Barisan.

"This is the kind of government we want. I believe the majority of the local people are happy with the government's decision that finally put the coal plant issue to rest," he said.

In September 2009, Najib disclosed Felda Sahabat in Lahad Datu as the proposed site for the construction of the coal-based power plant.

Currently, the electricity supply capacity in the eastern coast of Sabah is 200 megawatts from a diesel-based power plant.

Environmental groups such as Green Surf have protested against the construction of the coal-based power plant, which they consider as "dirty" energy, and called on the government to scrap the plan.

However, in August last year, the Environment Department had rejected the Detailed Environmental Impact Assessment (DEIA) for the project but Tenaga Nasional Bhd (TNB), in its 2010 Annual Report, mentioned that "a reviewed DEIA report will be submitted for study and approval" for a 300MW plant.

TNB Awards RM2.149 Billion Ulu Jelai Hydro-Electric Project Contract To Two Consortiums

KUALA LUMPUR, Jan 12 (Bernama) -- Tenaga Nasional Bhd awards contracts worth RM2.149 billion to two consortiums to undertake construction of the Ulu Jelai hydro-electric power plant in Pahang.

The plant, to be operational by July 2016, entails construction of one dam and installation of two hydro turbines and generators in a underground power station with a total installed capacity of 372 megawatt.

The consortium of Tindakan Mewah Sdn Bhd and Salini Costruttori S.p.A Consortium will be responsible for the main civil, electrical and mechanical works, it said in a filing to Bursa Malaysia Wednesday.

The main civil works consists of the construction of a dam, two water transfer tunnels and an underground powerhouse.

Electrical and mechanical works involve the design, manufacture, erection, testing and commissioning of two power-generating plants, each with a capacity of 186MW and the associated electrical and mechanical equipment.

The contract price is EURO307 million and RM818.1 million, which is equivalent to RM2.050 billion, it said.

The consortium of SMEC International Pty Ltd and SMEC (Malaysia) Sdn Bhd will provide detailed engineering design for the main civil works, engineering design review for electrical and mechanical works, project management and site supervision, said Tenaga.

The contract price is AU$D22.1 million and RM31.1 million, respectively, equivalent to RM99.6 million at the current exchange rate, it said.

The contract period for the development of the Ulu Jelai Hydroelectric Project is five years. Payment to the contractors will be made according to the progress of the project.

The above cost will potentially result in an increase in the company's net assets by about 7.1 per cent, said Tenaga.

The project, in the Cameron Highlands district, is part of ongoing efforts by Tenaga to provide peak load capacity to meet increasing demand for electricity and improve power system security by using renewable energy and reduce carbon emissions.

The project comprises Susu Dam on Sungai Bertam, two diversion weirs on Sungai Lemoi and Sungai Telom for the diversion of flows from the adjacent catchment via transfer tunnel into Sungai Bertam.

The Project will involve the construction of one dam and the installation of two hydro turbines and generators in an underground power station with a total installed capacity of 372MW. The Project is located in the State of Pahang Darul Makmur, in the district of Cameron Highlands. The Project comprises of Susu Dam on Sg. Bertam, two diversion weirs on Sg. Lemoi and Sg. Telom for the diversion of flows from adjacent catchment via transfer tunnel into Sg. Bertam. The Project is expected to be completed and the station made operational by July 2016.

The first agreement is with SMEC International Pty Ltd and SMEC (Malaysia) Sdn. Bhd. Consortium which will provide detailed engineering design for the main civil works, engineering design review for the electrical and mechanical works, project management and site supervision. The contract price is AUD22.1 million and RM31.1 million, equivalent to RM99.6 million at the prevailing exchange rates.

The second agreement is with Tindakan Mewah Sdn. Bhd. and Salini Costruttori S.p.A Consortium. Under the contract, the Consortium will be responsible for the main civil, electrical and mechanical works.The main civil works consist of the construction of a dam, two water transfer tunnels and an underground power house. For electrical and mechanical works involves the design, manufacture, erection, testing and commissioning of two generating plant, each with a generating capacity of 186MW and the associated electrical and mechanical equipment. The contract price is EURO307 million and RM818.1 million, which is equivalent to RM2.050 billion at the prevailing exchange rates.

The contract period for the development of the Ulu Jelai Hydroelectric Project is 5 years of which the payment to these contractors will be made in accordance with the progress of the project.

The above cost will potentially result in an increase in the Company’s Net Assets by approximately 7.1%. This Project is part of the on-going efforts by TNB to provide peak load capacity in order to meet increasing electricity demand and improve power system security by using renewable energy and at the same time reduce carbon emissions.

None of the Directors or Major Shareholders of TNB or persons connected to the Directors or Major Shareholders of TNB has interest, direct or indirect in the said Agreements.

Chocolate eaters may have healthier hearts

2010-12-21T07:42:00.000+08:00

Older women who eat more chocolate are less likely to develop heart problems over a nearly 10 year period, new study findings report.

Women older than 70 who ate chocolate at least once a week were 35% less likely to be hospitalised or die from heart disease over the course of study, and nearly 60% were less likely to be hospitalised or die from heart failure.

Mill Coal Grinder

Vertical Mill Coal Grinder

Coal is widely used in the world. One of the major usage of coal is a major contribution to combustion at steel industries and thermal power plants.

Basically consumption of coal thermal plant is quite large. Imagine, normally plant with 2000MW using fine coal to generate electricity which the consumption of coal around 10,000 tonne to 15,000 tonne per day. That's why criteria for choosing coal mill is very important to improve utilization of coal.

Coal mill grinder or coal mill crusher is used to crush coal or to make coal in very small size. The coal need to be processed and crushed into different sizes, 0 ~ 25 mm particle size for coal gas stove , 25 ~ 8 mm for steam locomotive, 25 ~ 6 mm for the industrial furnace, and coal power plant requires grain coal of 0 ~ 25mm.

This picture a part of process in thermal power plant. The process is start from the coal inlet and introduce to the mill crusher. The end at the pulverized coal outlet.

Hydro Plant Major Overhaul

2010-12-19T01:35:00.001+08:00

Normally hydro plant doing major overhaul around 10 years for a cycle. Why we need such work to be carry out?

The main reason for setting up overhaul is to prevent unscheduled outages from failure of equipment. Since a machine which already run for a long period have lot of wear and tear and need to be treated well to make it last longer.

In order for the overhaul to proceed smoothly and to accomplish all the work required, planning should start well before the overhaul starts.

I am going to prepare roughly on what we have to do or prepare before we can carry out such a big job. Maybe it will takes some time to complete all the checklist. Anyway I will try to find out the data first before write an entry about hydro major overhaul.

DCS Vs SCADA

2010-12-18T01:31:00.001+08:00

DCS Vs SCADA

DCS is process oriented: it looks at the controlled process (the chemical plant or whatever) as the centre of the universe, and it presents data to operators as part of its job.

SCADA is data-gathering oriented: the control centre and operators are the centre of its universe. The remote equipment is merely there to collect the data--though it may also do some very complex process control!

A DCS operator station is normally intimately connected with its I/O (through local wiring, FieldBus, networks, etc.). When the DCS operator wants to see information he usually makes a request directly to the field I/O and gets a response. Field events can directly interrupt the system and advise the operator.

SCADA must operate reasonably when field communications have failed. The 'quality' of the data shown to the operator is an important facet of SCADA system operation. SCADA systems often provide special 'event' processing mechanisms to handle conditions that occur between data acquisition periods.

Pergau Hydroelectric 600MW

Pergau Water Intake at Kuala Yong Dam

Hydroelectric dam on the Pergau River in Malaysia, near the Thai border. Building work began in 1991 with money from the UK foreign aid budget. Concurrently, the Malaysian government bought around £1 billion worth of arms from the UK. The suggested linkage of arms deals to aid became the subject of a UK government enquiry from March 1994. In November 1994 a High Court ruled as illegal British foreign secretary Douglas Hurd's allocation of £234 million towards the funding of the dam, on the grounds that it was not of economic or humanitarian benefit to the Malaysian people.

What is the Main Inlet Valve?

2010-12-11T07:02:00.003+08:00

Main inlet valve or shortly we say MIV is the spherical valve which installed before water enter into spiral casing of the hydro turbine.

Water from the dam go to the penstock and before water enter the turbine, MIV is a component in between stop the water for small maintenance purpose in the turbine hall.
