The amount of oxygen scavenger required in a boiler water is related to the concentration of dissolved oxygen, the residual level of scavenger specified, and the percent of blow down performed. Water temperature, water composition, and reaction time also have considerable impact on the ultimate quantity of scavenging chemical needed:
Make-up water to steam boilers should be treated with oxygen scavengers to avoid serious corrosion problems. Fresh water contains dissolved oxygen. Oxygen together with high temperature is highly corrosive for the carbon steel piping used in steam systems. To avoid corrosion the oxygen in the make-up water for saturated steam production should be removed by using some kind of scavenger chemicals and/or deaeration towers.
