Feed water deaeration has an direct effect on the operating life and reliability of the boiler and the thermal power system. In this paper, the demands of dissolved oxygen in feed water and condensate water for industrial boilers and power stations have been discussed. The application of deaerating technologies in industrial boilers and power stations has been summarized. The main features of different deaerating technologies have been analyzed. The main factors influencing deaerating efficiency of thermal deaerators have been summarized, which will give a reference for the design and operation of thermal deaerators.
