Control of carbon dioxide and oxygen-induced corrosion can be achieved chemically at a cost while under steady state operating conditions. The majority of chronic corrosion concerns associated with steam condensate handling and uilizatino systems are either mechanically assisted or mechanically / chemically assisted under non-steady state considtions. It has become apparent that corrosion product monitoring, system surveying and metallurgical failure analysis are of greater importance than chemical monitoring as the majority of the corrosion is mechanically induced. The interactive variables which lead to atypical post boiler depreciation and mitigation methods thereof will be discussed.

Key words: pretreatment, satellite feeding, subcooling, condensate drainage, distribution, control valve, steam trap, fine sizing, selection, back pressure, collapse, cavitation, erosion corrosion, control logic.
