The purpose of a deaerator is to reduce dissolved gases, particularly oxygen, to a low level and improve a plant's thermal efficiency by raising the water temperature. In addition, deaerators provide feedwater storage and proper suction conditions for boiler feedwater pumps.

6/1/2017 · Boiler Efficiency and Deaerator Performance Deaerators for boiler feed water are a vital component to a reliable feed water system. At the same time, it can be the heart of your thermal-energy and boiler mass-flow database used to identify energy-saving opportunities and critique plant operations.

8/8/2017 · Deaerator equipment is designed to reduce dissolved corrosive gases in the boiler feed water. This is done at times by heating the water to the temperature closed to the saturated temperature at the pressure within the deaerating equipment. A deaerator, generally, reduces the oxygen level to 7ppb.

5/5/2018 · Usually, a boiler feed water tank (short: bfw tank) for storing and secondary deaeration of the water is arranged downstream of the deaerator. Thermal deaeration is a continuous process. During operation, make-up water, condensate and heat (usually by injection of heating steam) flow continuously in, while deaerated boiler feed water and vent steam flow continuously out.
