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 oF, with feedwater at 0 Psig and 212 oF. 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.

Boiler load - The horsepower, lbs of steam per hour, or BTU is the rating indicating the maximum capacity of a boiler. When a boiler operates at its maximum rated capacity, it is referred to as maximum load. If the load varies from hour to hour, it operates at a varying load.Load and load variations can influence the amount of chemicals required for treatment and the treatment controls required.

The load factor is a dimensionless number equal to the average load divided by the peak load. For example, if the average load is 66 kWh/d (or 2.75 kW) and the peak load is 10.5 kW, the load factor is 2.75 kW/10.5 kW = 0.26.

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)

The nature of the facility’s operation will dictate whether a steam or hot water boiler should be used. Hot water is commonly used in heating applications with the boiler supplying water to the system at 180 °F to 220 °F. The operating pressure for hot water heating systems usually is 30 psig to 125 psig.

Another important factor in instantaneous boiler response is steam chest volume. All steam piping and boiler steam space will maintain a reservoir of steam. If you determine the volume of this area, you can use steam specific volume data to determine the mass of steam stored. For example, if a boiler has a steam space of 3 cubic feet and there are
