Boiler Feedwater - an overview | ScienceDirect Topics

Boiler feed water quality is limited owing to problems of (1) scaling, (2) corrosion, and (3) foaming. In order to avoid these problems, the quality guidelines shown in Table IV have been adopted. Data in Table IV show a major difference between cooling water and boiler feed water quality constraints, in that boiler feed water has a strong relationship between water quality and the pressure of

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

What Is a Boiler Feed Water Treatment System and

Treating boiler feed water is essential for both high- and low-pressure boilers. Ensuring the correct treatment is implemented before problems such as fouling, scaling, and corrosion occur, will go a long way in avoiding costly replacements/upgrades down the line. An efficient and well-designed boiler feed water treatment system should be able to:
