Require the calculation for Hydrazine dosing in Boilers based on O2 content. Similarly for amine dosing in boiler based on PH. 1. Reaction of hydrazine NH2NH2+O2-->2H2O+N2 indicates dosing of 1 gr NH2NH2 / gr O2. In practice 1.5 to 2.0 gr NH2NH2 / gr O2 is applied, probably because hydrazine protects metal from corrosion by converting Fe2O3 to Fe3O4.
