The term "oxygen scavenger" implies that this type of boiler water treatment chemical functions as corrosion inhibitor by reducing molecular oxygen to noncorrosive compounds. However, oxygen scavengers can also act as passivating corrosion inhibitors for carbon steel and may decompose at boiler temperatures. Therefore, one must consider all of their hydrothermal reactions and the effects of the resulting reaction products on the entire steam generating system. If there are volatile reaction products, the intended use of the steam must also be considered.
