Each boiler is given a boiler horsepower (BHP) rating based on the steam output capacity at For this calculation you will enter the steam load in pounds per hour which will be divided by a constant of 345 This number represents the thermal energy rate required to turn 345 lbs of water at 212 °F to steam in one hour

Read MoreThe from and at rating is widely used as a datum by shell boiler manufacturers to give a boiler a rating which shows the amount of steam in kg/h which the boiler can create from and at 100°Cat atmospheric pressure Each kilogram of steam would then have received from the boiler

Read MoreThe Boiler Horsepower (BHP) is the amount of energy required to produce 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 131547 times a normal horsepower
