Jul 02, 2019 · Boiler deaerators commonly are used to remove oxygen and other gases from the water that feeds into boilers that generate steam. Deaerators are useful because they remove the gases that attach to the metallic components of the steam system and cause corrosion by forming oxides, or rust.
Deaerators are designed to operate on steam from the boiler, exhaust steam, or both. If exhaust steam is currently going to waste, it may be used in the deaerator — reducing the fuel expense of the plant approximately 1% for each 10 °F rise in boiler feedwater temperature. NOTE: Exhaust steam must be free of oils and
In addition to removing free oxygen and carbon dioxide, a deaerator using steam as the scrubbing gas provides the advantage of heating boiler feedwater. Adding hot feedwater to a boiler greatly reduces the chance of thermal shock caused by the expansion and contraction of heating surfaces.
