Deaeration is the process of removing the dissolved oxygen from the boiler feed water. Additionally, in the deaeration process, the CO² is also removed. Removal of these two gases is important in boiler feed water as both of the segases promote corrosion in the boiler or steam system.
-
An additional benefit of a deaerator is the high water feeding temperature to boiler, so risk of low temperature corrosion on the smoke side is decreased and thermal shocks are liminated in the boiler. Corrosion created by O² and CO² gases is shown.
Carbondioxide Corrosion
Longitudinal slits inside condensate pipes are typical sign of CO2 corrosion.
Oxygen Corrosion
Small hollows at water side of boiler tubes are typical sign of O2 corrosion.
