Figuring Out Boiler Horsepower

 

Boiler horsepower is not related to mechanical horsepower. It is a boiler industry rating that predicates the amount of saturated steam a boiler will generate starting with water at 212 degrees Fahrenheit and 0 pounds per square inch gauge (psig--meaning atmospheric pressure) and ending with steam at 212 F and 0 psig. For example, if a boiler is rated at 50 bhp, then it will produce 50 bhp x 34.5 pounds per hour (lb/hr) = 1,725 lb/hr of steam under these conditions.

BHP is still used to measure boiler output in industrial boiler engineering in North America. One Boiler Horsepower (1BHP) is equal to a bolier thermal output of 33 475 BTU/h (British Thermal Units per Hour) or 9.81055407 kW (Kilowatts). This is the energy rate required to evaporate 34.5 lb (pounds) or 15.648936765 kg (kilograms) of fresh water at 212 °F (degrees Fahrenheit) or 100 °C (Celsius) in one hour (1h).

About how to figure out boiler horsepower, boiler horsepower was used in USA, Australia, and New Zealand and have been calculated in different ways.
PBoHP = A / k
where
PBoHP = boiler horsepower
A = heat transfer area (ft2)
k = standard area (ft2)
