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

Boilers Guide | All about Boilers

Boilers are pressure vessels designed to heat water or produce steam, which can then be used to provide space heating and/or service water heating to a building. In most commercial building heating applications, the heating source in the boiler is a natural gas fired burner. Oil fired burners and electric resistance heaters can be used as well.
