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

Boiler thermal Design calculation 4. A starting point is always to determine the heat load for the exchanger, using the basic thermodynamic equation Q = m.Cp. (delta T). A heat balance must be achieved. TEMA has guidelines for the maximum permissable deviation (I speak under correc but I think it is 2%).

Boiler efficiency, in the simplest terms, represents the difference between energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units will result in substantial fuel savings.

Boiler Efficiency 76.7% 75.1% 76.6% 74.0% 74.8% 71.4% Calculated Average Boiler Efficiency 75% Formula = Boiler Efficiency (ŋ) = Steam Quantity x ( Steam Enthalpy - Feed Water Temperature) Coal Consumption Quantity x Calorific Value of Coal

This method calculates boiler efficiency by using the basic efficiency formula-η=(Energy output)/(Energy input) X 100.
