The BTU/hour to Boiler Horsepower calculator is used to help size both steam and hot water boilers. This calculation translates the heat transfer input requirement to BHP. To do so, we divide the BTU/hour by a constant of 33,475. This constant represents water being converted to steam, which is 34.5 pounds of water multiplied by 970.3 BTU/lb, or latent energy. For this calculation, you will enter the BTU/hr of your operation along with the efficiency of your boiler.

Nov 03, 2006 · What is the boiler horsepower of a boiler generating 21,500 lbs of steam per hour at 155 psi? The factor of evaporation is 1.08. BHP = (LB/HR*fe)/34.5 BHP = (LB/HR*fe)/34.5 BHP = 21500 * 1.08 / 34.5 BHP = 673 Where, BHP boiler horsepower Lb/Hr pounds per hour Fe factor of evaporation (can be assumed to be equal to 1)
