What is a Boiler Deaerator and How Does It Operate?

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?

Corrosionpedia - What is Scale? - Definition from

As the scale is not uniform, the corrosion becomes localized rather than spread evenly over the surface of the metal. Scale formation can greatly affect heat transfer performance. One-millimeter-thick scale, for example, can add 7.5% to energy costs, while 1.5 mm adds 15% and
