What is a Boiler Deaerator and How Does It Operate?

2020-5-9 · 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. Both oxygen and carbon dioxide are responsible for How Does a Boiler Deaerator Work?
