Boiler Horsepower - Engineering ToolBox
Boiler horsepower - a power unit from the 19 th-20 th centuries - was used to rate the capacity of a boiler to deliver steam to steam engines.. A common definition of one boiler horsepower is the amount of energy required to produce 34.5 pounds (15.65 kg) of steam per hour at pressure and temperature 0 psig (0 bar) and 212 o F (100 o C) - with feed water at pressure 0 psig and temperature 212 o F.
boiler horsepower - Sizes
Each 10 square feet of surface represented 1 boiler horsepower, so a boiler with 100 square feet of heating surface would be rated at 10 boiler horsepower. Because boilers vary greatly in design and efficiency, this is a very inadequate way of rating them.
ABMA Five Sq. Ft per Bhp White Paper - POST BOARD 1
related the Boiler Horsepower to square feet of heating surface, only to the net output generated by the boiler, with steam boilers expressed in measurements of 34.5 pounds per Boiler Horsepower from and at 212° F, and with hot water boilers expressed in measurements of 33,475 Btu/hr per Boiler Horsepower.

Definition of boiler horsepower. Convert between boiler horsepower and other major units of power. A unit of power, 19 th – 20 th centuries, defined by the . Determining Boiler Capacity from Heating Surface. Hi There: I was once told that there is an equivalence between boiler capacity (steaming rate) and the heat exchange surface area.
Determining Boiler Capacity from Heating Surface Area - Heat ...
The nameplate states that the surface area is 3089 sq ft. The burners I know are oversized, but I am trying to determine by how much they are oversized. I think the surface area is the answer, but I need to convert this area into boiler horsepower, or kW or MMBTU/hr. Any input much appreciated. Thanks.
