What Are the Properties of Demineralized Water and …

Boilers that generate steam to power turbines require high-pressure boilers and therefore more complex feed water treatment system to remove as many impurities as possible. When steam is produced inside the boiler, the water particles collect and condense, then are recycled and used as part of the boiler feed water.

Boiler water treatment - Lenntech

The water treatment facilities purify and deaerate make-up water or feed water. Water is sometimes pretreated by evaporation to produce relatively pure vapor, which is then condensed and used for boiler feed purposes. Evaporators are of several different types, the simplest being a tank of water through which steam coils are passed to heat the
