Dosing Calculaion-Hydrazine/ammonia-Boiler

Same reference is used for (1), results seem precise in this case. Hydrazine injection into BFW (boiler feed water) of 7 mg O2/l was recently specified for residual content of 0.2-0.6 mg/l in boiler drums, but hydrazine was replaced by carbohydrazide due to its toxicity.
