GB 1576-2001 is the water quality standard for industrial boilers. The water quality of industrial boilers affects their operation safety and efficiency. The standard stipulates the limits of water quality indicators such as feed water, Hardness of boiler water, acid alkalinity, dissolved oxygen, and conductivity according to different types of industrial boilers. For example, hot water boilers and steam boilers have their own focuses. Clear water quality detection methods and standardize monitoring Frequency. Meeting the water quality standards can prevent boiler scaling and corrosion, prolong service life, and reduce energy consumption and safety risks. Provide guidelines for the water quality management of industrial boilers to ensure the safe, stable and efficient operation of industrial production.
