Boiler water treatment - Lenntech

The treatment and conditioning of boiler feed water must satisfy three main objectives:. Continuous heat exchange; Corrosion protection; Production of high quality steam; External treatment is the reduction or removal of impurities from water outside the boiler. In general, external treatment is used when the amount of one or more of the feed water impurities is too high to be tolerated by the

Coal - TVA

Each unit produces electricity by burning coal in a boiler to heat water to produce steam. The steam, under tremendous pressure, flows into a turbine, which spins a generator to produce electricity. The steam is cooled, condensed back into water, and returned to the boiler to start the process over. Find out how a coal-fired power plant works.

Water Handbook - Boiler Feedwater Deaeration | SUEZ

only a small quantity of steam must be vented, because most of the steam used to scrub the water is condensed and becomes a part of the deaerated water; In order to deaerate the boiler feedwater, water is sprayed into a steam atmosphere. This heats the water to within a few degrees of the temperature of the saturated steam.
