Is there an indicator for hydrazine content among the water quality parameters for boiler water?
Thread Content
May I ask what are the quality parameters for boiler water? I have also checked some national standards, but I couldn’t find any specifications regarding ammonia or hydrazine content. Are there any experts in boiler technology who are aware of this parameter?
We only analyze iron, silica, and conductivity
Hydrazine reacts with dissolved oxygen; if excessive oxygen is detected, it means there isn’t enough hydrazine. Even if an excess amount is added, it will evaporate from the top of the deaerator, and this will not affect the properties and parameters of the boiler water, as its boiling point is 113 degrees
What worries me is that the excessive amount of urea in the boiler water could corrode the material of my process pipes
Thank you. The diamine level is less than 10PPM, right?
According to DL/T 561-95, the amount of hydrazine added to boiler feed water is specified as 10-30 ug/l or 10-50 ug/l.
