The article discusses the primary reasons for making deaeration part of a boiler/steam/condensate cycle. Deaerating boiler feedwater can lengthen the life of equipment as well as lower costs of replacement and maintenance. There are five advantages of deaerating boiler feedwater including oxygen removal which prevents oxygen corrosion, carbon-dioxide removal which also prevents corrosion and improved operation by reducing the chance of thermal shock caused by expansion of heating surfaces.
