Deaerators are mechanical devices that remove dissolved gases from • Storage Tank boiler feedwater through a preheating process. Deaeration protects industrial steam systems from the effects of corrosive gases • Heating Apparatus by reducing the concentration of dissolved oxygen, carbon dioxide and other • Feed Pump(s) non-condensable gases to a level where corrosion is minimized. • Water Level Controls A dissolved oxygen level of 5 parts per billion (ppb) or lower is needed to prevent corrosion in most high-pressure (>200 pounds per square inch) boilers. While oxygen concentrations of up to...
