The national standard GB1576-2001 \"Water Quality for Industrial Boilers\" requires that the feed water for steam boilers should be treated (through feed water treatment). For steam boilers with a rated evaporation capacity of ≤2 t/h and a rated steam pressure of ≤1.0 Mpa, in-water chemical treatment can also be used; however, close monitoring of scaling, corrosion, and water quality in such boilers is necessary, and proper handling of chemical addition, sludge removal, and cleaning must be carried out. Deoxidization is required when the boiler’s rated evaporation capacity is ≥6 t/h. In boilers with a rated evaporation capacity of <6 t/h, deoxidization measures should be taken if local corrosion is detected. The oxygen content in the feed water for boilers supplying steam to turbines should be ≤0.05 mg/l. For hot water boilers with a rated power of ≤2.8MW, chemical treatment inside the boiler can be used; however, close monitoring of scaling, corrosion, and water quality is necessary, and the chemical treatment process must be carried out properly. When the rated power of a boiler is ≥4.2MW, deoxidization is required for such hot water boilers, while for those with a rated power of <4.2MW, the feed water should be deoxygenated as much as possible.
The national standard GB1576-2001 \"Water Quality for Industrial Boilers\" stipulates that for steam boilers, external chemical treatment should be used for the feed water. For steam boilers with a rated evaporation capacity of ≤2 t/h and a rated steam pressure of ≤1.0 Mpa, internal chemical treatment can also be employed; however, close monitoring of scaling, corrosion, and water quality in such boilers is necessary, and proper handling of chemical addition, sludge removal, and cleaning must be carried out. Deoxidization is required when the boiler’s rated evaporation capacity is ≥6 t/h. In boilers with a rated evaporation capacity of <6 t/h, deoxidization measures should be taken if local corrosion is detected. The oxygen content in the feed water for boilers supplying steam to turbines should be ≤0.05 mg/l. For hot water boilers with a rated power of ≤2.8MW, (chemical treatment inside the boiler) can be used; however, close monitoring of scaling, corrosion, and water quality in the boiler is necessary, and chemical treatment must be carried out properly. When the rated power of the boiler is ≥4.2MW, hot water boilers should undergo (deoxidization), while for hot water boilers with a rated power of <4.2MW, the feed water should be (deoxidized as much as possible).
