What do people use as chemical deoxidizers for boiler feed water?
Thread Content
For the boiler feed water from manufacturers in the surrounding area, hydrazine is added to it after the spin-deaerator. Hydrazine is a hazardous chemical that is toxic and prone to explosion; its transportation, storage, and handling present many difficulties, and its toxicity is also harmful to employees. I’m looking for a substitute. I’m not sure what others use – from what I’ve read online, there are dimethyl oxime, sodium D-ascorbate, and acetaldoxime. I wonder if these are actually used, and what their effectiveness and cost are like If anyone knows, please give some guidance. Thank you.
I have used dimethylhydroxime; under the same conditions, it is less effective at removing oxygen compared to hydrazine. I have not used any other substances
Dimethyl homoxime can very easily affect the pH; too much of it should not be used. You can communicate with each other at 15615812088
My company used carbazide in the past, but under the same conditions it is not as effective as hydrazine, and its cost is also higher; that’s why we still use hydrazine nowadays
