Water Analyser QUZ Cabin

Purpose of the Water Analyser System in Coal Fired Power Plant

To ensure that steam and water are of a consistently high quality, they are sampled and chemically analysed at several points in the steam water cycle to monitor their quality. The information from the analyses is used by the operator to control the chemical dosing system.

To detect a circulating water leakage in the tube sheets of the condenser. The steam and water chemical sampling equipment is designed to condition samples of feed water, boiler water and steam, by reducing the pressure and temperature of the samples to a suitable level such that their chemical composition may be determined by the appropriate dedicated analysers.
