At typical boiler temperatures, oxygen corrosion, which is a chemical reaction, can be hundreds of times faster than at ambient temperature.

Thus, effective and complete deaeration of boiler feedwater in steam generating plants is a vital step in protecting boilers, turbines, condensers, pumps, piping, etc., from the ravages of corrosion and subsequent costly failures.

Because an efficiently operated deaerator is an important part of any steam system, it should be given proper attention on a daily basis, and if at all possible, an annual inspection.

Case histories cited in the paper indicate that "deaeration" principles are not widely understood or fully appreciated by operating plant personnel.

Deaeration principles are reviewed in the paper and daily operational inspections and checks are listed.

A "take-down" annual inspection procedure is outlined.
