Deaerator - Wikiped

2019-10-10 · A deaerator is a device that removes oxygen and other dissolved gases from liquids: From Water, such as feedwater for steam-generating boilers. Dissolved oxygen in feedwater will cause serious corrosion damage in a boiler by attaching to the walls of metal piping and other equipment and forming oxides (rust). Dissolved carbon dioxide combines

What is a Boiler Deaerator and How Does It Operate

2019-10-22 · 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?

What is Oxygen Scavenger - AONG websi

Is oxygen corrosive? Yes. Oxygen is a highly reactive gaseous element. In the presence of steel, the corrosion rate of oxygen doubles for each 30°F rise in temperature. For example, in a boiler system operating at 400 psig and 444°F, the corrosion rate for oxygen is 256 times more reactive than at room temperature.. How does oxygen attack metal surfaces?
