The assessment of the effect of carbon dioxide on the

Oxygen corrosion is extremely fast when water boils or steam condensates. Corrosion with hydrogen depolarization occurs in the presence of hydrogen ion in water, in other words, acid. When carbon dioxide is dissolved in water, H 2 CO 3 carbonic acid is formed, which dissociates into hydrogen ions H + and HCO 3 – bicarbonate.

What is a Boiler Deaerator and How Does It Operate? …

2019-6-28 · 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?

Oxygen attack in boilers - Lenntech

Oxygen is highly corrosive when present in hot water. Even small concentrations can cause serious problems: iron oxide generated by the corrosion can produce iron deposits in the boiler. Oxygen corrosion may be highly localized or may cover an extensive area. Oxygen attack is an electrochemical process that can be described by the following
