One day, I heard a man tolding that an excess of hydrazine in boiler water causes generalized corrosion in the steel surfaces.
I have never read anything like that, and never experienced this. As far as I know, hydrazine is an oxygen scavenger for high pressure boilers, a reductor agent and it usually promotes steel passivation AGAINST corrosion. So I think that man is completely wrong (he's a lunatic who used to say himself is the best tecnician in this area).
Please, could any member of the forum give us an opinion?
Thanks a lot.
