Controlling the water quality of boiler feed water is mainly to prevent boiler fouling, corrosion and salt accumulation. Usually low pressure boilers use softening as make-up water, medium pressure uses de-alkali and desalinated water as make-up water. As make-up water.

Power plant boiler industry water quality standards
It meets the national or industrial boiler feed water standards (GB1576-79, DL / T561-95), and is suitable for the water quality requirements of medium and high pressure boilers. (Super) pure water with a resistivity of 0.5-10MΩ.CM.
