..., corrosion in the pre-boiler and boiler sections is due to oxygen pitting. Since the boiler is pressurized, the only means of oxygen ingress during normal operation occurs through the feedwater. The primary deaeration of the feedwater is initiated in a mechanical deaerator. The feedwater is contacted...
