WebVacuum deaerators remove dissolved gasses from boiler feeds. Removing these gasses via vacuum is more economical than removing them through chemicals. The systems reduce corrosion in boiler tubes caused by dissolved oxygen and carbon dioxide. Deaeration is based on several principals. However, Henry’s Law is the driving principle. WebIn addition1 central station deaerators serving turbines that also operate over a wide range of load conditions can get better deaeration with a tray-type unit. This is not an indictment of spray-type deaerators. They do have definite places of application, and, when operated within their specified limits, will do an excellent job of gas removal.
