Thermo Ramsey Granuflow Detector GTR 130

The Thermo Ramsey Granuflow non-contact flow sensor ideally for monitoring flow in pipeline, ducts, air-slides, and at transfer points of vibrating chutes, conveyor belts and bucket elevators. Currently used at the SO3 Injection System (Boiler Side) in our coal fired power plant to monitor sulfur dosing.

Thermo Ramsey Granuflow Detector GTR 130

The GTR 130 sensor has no moving mechanical parts. This eliminates wear of the sensor and makes the instrument maintenance and trouble-free.

Details Specification:

Description : Flow Switch
System : SO3 Injection System (Boiler Side)
Model : Granuflow GTR 130
Maker : Thermo Ramsey
Input volatage : 20-30 V AC/DC Relay contact (NO)
Rating max: 250 V 4A

Boiler Functional Block Generally

This function block actually draw and has been contributed one of my best friends when he worked with me a few years ago in our power plant.

He is very hardworking and one of the best staff in instrumentation department. Thanks my friend.

Combustion Air Flow

Even today is Saturday, I am going to my office to finish some paper work which need to be submitted end of next week. Also get bored at home and need to do better things. I am not posting my work for today, but this data or report is contributed by my colleague.

Regarding of the fluctuating right hand side (RHS) combustion air flow, minor leak was found at air inlet continuous air purge. Some action has been taken to clear the defect.

Action taken:

1) Search the leakage using snoopy. Found as per picture above.

2) Tighten all fittings or connections from sensing line to transmitter manifold.

3) Also tighten the leak parts unfortunately the leakage still exist. The only way to do is dismantle the purge air flow regulator seems that the origin fittings of flow regulator doesn't fitted very well with the white tape.
