Determine boiler horsepower from heat transfer area
Sponsored Links
Boiler horsepower is used rating a boiler's capacity to deliver steam to a steam engine.
The amount of energy needed to produce 34.5 pounds (15.65 kg) of steam, per hour, at a pressure and temperature of 0 Psig (0 bar) and 212oF (100oC), with feed water at 0 Psig and 212oF. One boiler horsepower is about 33,479 Btu per hour (about 9,810 watts, 8430 Kcal/Hr).
Boiler horsepower can be determined from the heat transfer area
PBoHP = A / 17 (1)
where
PBoHP = boiler horsepower
A = heat transfer area (ft2)
