BASIC WATER TREATMENT OF STEAM BOILERS

As sentinels of the heart of dry kiln plants, boiler operators have control over two basic aspects of the chemical program; blow down and chemical feed. Blow down requirements are determined by the type and amount of impurities that exist in the makeup water. Blow down rates of course directly affect chemical feed rates. Therefore,
