Unit Conversion--How to Calculate Boiler Horsepower

HP mean Horse power and BHP mean Boiler Horse power. Our clients are usually confused with the two units. Now, let us make them clear.

Boiler Horsepower - BHP

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 ℉, with feedwater at 0 Psig and 212 ℉.
“Boiler horsepower, a unit of measurement of power of steam boilers” from Wiki.
A BHP is equivalent to 33,475 BTU/Hr or 8430 Kcal/Hr and it should be noted that a boiler horsepower is 13.1547 times a normal horsepower.

Converted HP into LB
Horsepower (hp) can be converted into lbs of steam by multiplying hp with 34.5.
Example - Boiler Horsepower to lbs of Steam Conversion
200 hp x 34.5 = 6900 lbs of steam per hour
Converted LB into HP
Lbs of steam can be converted to hp by dividing lbs steam per hour by 34.5
Example - Lbs of Steam to Boiler Horsepower Conversion
5000 lbs of steam / 34.5 = 145 hp boiler
1 horsepower (boiler)= 33445.6 Btu (mean)/hr= 140671.6 calorie/min (thermo)= 140469.4 calorie (mean)/min= 140742.3 calorie (20℃)/min 9.8095x1010 erg/sec= 434107 foot-pound-force/min= 13.1548 horsepower (mech)= 13.1495 horsepower (electric)= 13.3372 horsepower (metric)= 13.1487 horsepower (water)= 9809.5 joule/sec= 9.8095 kilowatt
