Deaerator - Wikipedia

A deaerator is a device that removes oxygen and other dissolved gases from water, such as 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 (rust). Dissolved carbon dioxide combines with water to form carbonic acid that causes further corrosion.
