What is a Boiler Deaerator and How Does It Operate? - MPC

Thermal deaerators are commonly used to remove dissolved gases in feedwater for steam-generating boilers.Dissolved oxygen in feedwater will cause serious corrosion damage in a boiler by attaching to the walls of metal piping and other equipment and forming oxides (like rust). Dissolved carbon dioxide combines with water to form carbonic acid that may cause further corrosion.
