　　Softening water equipment manufacturers for industrial boilers mainly use physical or chemical treatment technologies for primary or secondary desalinated water,boiler water,and steam condensate water in the boiler system.That is,by adjusting the pH of desalinated water,the acid uniform corrosion of the feedwater system is controlled,the oxygen corrosion of the boiler thermal system is controlled by the deaerator and deaerator,the scaling,corrosion,deposition,and entrainment inside the furnace are controlled by chemical treatment,and the corrosion of condensate water is controlled to prevent acid and oxygen corrosion of the steam condensate system.
