Brief Description: Dissolved oxygen in water can cause oxygen corrosion in the inner gallbladder of boilers, which can reduce the service life of boilers slightly and reach critical explosion state seriously, threatening the safety of life and property of users. The traditional method of boiler deoxidization is thermal deoxidization or chemical deoxidization. The former is used in most boilers. Thermal deaeration needs to consume steam, and some valve steam emissions will lead to a lot of energy waste. Ejik membrane deaerator is a new type of deaeration method for boiler feed water. The deaeration effect is much better than the traditional process, and the operation cost is much lower.
