Boiler Feedwater Treatment (Part I) Why Water Treatment

Impurities in water become an important consideration when water is to be used for steam generation. With the trend toward higher-pressure boilers, pretreatment has become the key to successful operation of industrial power plants. Feedwater must be pretreated to remove impurities to control deposition, carryover, and corrosion in the boiler system. Poor quality water gives poor quality steam
