Boiler Water Treatment - Why is It Important ? - Brigh

2020-5-1 · Boiler water quality is of prime concern to all boiler operators. The process of water treatment in boilers is not limited to producing high quality DM water. The stringent water chemistry requirements of Supercritical power plants makes water treatment in boilers a very critical aspect of power plant operation. This necessitates the use of a high quality water treatment system.

Why are we hydrazine dosing in thermal power plant?

Why are we hydrazine dosing in thermal power plant?

Hydrazine is a reducing agent and we use it primarily to control oxygen levels in the boiler. Due to the high temperatures in a boiler, chemical reactions happen very quickly and oxygen in even small amounts can cause significant corrosion. The ir

Boiler Feed Water Treatment Demineralization

Boiler Feed Water Treatment Demineralization

2020-5-9 · For continuous supply of feed water to boiler, after removing impurities, there are two types of plant generally incorporated. These are: Demineralization plant (D M plant); Reverse Osmosis plant (R O plant); Demineralization plant employs a chemical method to separate out the dissolved salt in raw water. But reverse osmosis plant employs a simple physical method to separate the dissolved salts.
