    passivate, or protect the metal surfaces in the boiler, and hydrazine is used as a passivating agent as well as an oxygen scavenger. Hydrazine decomposes in the boiler water at 400-600°F (250-1500 psia): 3N 2H 4 = 4NH 3 + N 2 (3-23) Feed rates of about 5 times stoichiometric are required for good oxygen scavenging.Learn More

    Where to dose hydrazine? zIt would be ideal to dose the hydrazine at deaerated water storage tank through a distributing pipe. zThe reaction time taken by hydrazine is longer particularly at low temperature. To have the advantage of time deaerator would be the right place. zIt would also prevent the corrosion of deaerator.Learn More
