Get A Quoteboiler horsepower (bhp or BHP): Measure of a boiler's capacity to produce steam. One BHP denotes ability to produce 34.5 pounds of dry steam per hour at 100°C (212°F), and corresponds to 10 square feet of heated surface, 33479 British thermal units (BTU), or 9.809 kilowatt per hour (equal to more than 13 mechanical horsepower).

Get A QuoteOne Boiler Horsepower = the evaporation of 34.5 pounds of water in one hour from and at 212 degrees f. To really figure out how much Boiler Horsepower your boiler makes, you have to measure the steam output and have test equipment. What heating surfaces are there in a steam locomotive? It depends on what you've got. Total area of surface in
