Why is hydrazinium hydroxide solution added to boiler feed water?
In order to prevent the boiler water system and pipelines from being corroded by oxygen, and to ensure the complete elimination of residual dissolved oxygen after thermal deaeration and oxygen leaking into the feed water due to loose pumps and water supply systems, it is necessary to add an appropriate amount of combined oxygen to the feed water. ammonia. Hydrazine (N2H4) is also called hydrazine, and its hydrate is commonly used, hydrazine hydrate (N2H4·H2O).
