• ### Steam Calculators: Boiler Calculator

Mar 17 2015 · Boiler Energy = Steam Energy Flow + Blowdown Energy Flow - Feedwater Energy Flow; Step 5: Determine Fuel Energy. Fuel Energy = Boiler Energy / Combustion Efficiency; Assumptions. Deaerator provides feedwater near the boiling temperature for the deaerator's set operating pressure. (Saturated Liquid) Steam Boiler and Blowdown Pressure are the same.

The Boiler Horsepower (BHP) is the amount of energy required to produce 34.5 pounds of steam per hour at a pressure and temperature of 0 Psig and 212 oF with feedwater at 0 Psig and 212 oF. A BHP is equivalent to 33475 BTU/Hr or 8430 Kcal/Hr and it should be noted that a boiler horsepower is 13.1547 times a normal horsepower.
