1Chapter 5 Boiler Water Treatment
Boiler water treatment encompasses the bene cial conditioning, both mechanical and chemical, of water used to generate steam or hot water in a boiler. The treatment process begins with the initial step of water preparation (pretreatment) and continues up to the nal step of condensate return blending with makeup water to become feed water. Therefore, the boiler water treatment program has to consider the impurities in the water, the design of the boiler system, the pretreatment equipment, the boiler design, the steam purpose, the steam contact, the condensate return line system design, the chemical feed system, chemical feed points, chemical treatment products, and plant capabilities. All of these come into play in determining the parameters of the boiler water treatment program.
