Deaerator - an overview | ScienceDirect Topics

Deaerator Cracking: A deaerator is a device widely used to remove oxygen up to 7 ppb and other dissolved gases like carbon dioxide completely from feedwater to steam-generating boilers. Environmentally assisted fatigue cracking of deaerators has been reported at the head-to-shell weld below the water level in the storage compartment.

Feedwater Treatment Systems - Steam Boilers and Steam

Pressurized Deaerators are employed in systems to preheat the feedwater and to remove non-condensable gases through a combination of heat and agitation. The primary difference between a "hotwell" and a "deaerator" tank is that the deaerator is a pressurized vessel and includes internal devices to create agitation to aid in the oxygen removal
