What is a boiler horsepower (BHP), a measurement unit of power

Boiler horsepower is a power measurement unit. One Boiler Horsepower (1BHP) is equal to a bolier thermal output of 33 475 BTU/h (British Thermal Units per Hour) or 9.81055407 kW (Kilowatts). This is the energy rate required to evaporate 34.5 lb (pounds) or 15.648936765 kg (kilograms) of fresh water at 212 °F (degrees Fahrenheit) or 100 °C (Celsius) in one hour (1h).

Steam Calculators: Boiler Calculator

Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

EFFICIENCY AND CAPACITY OF BOILERS - gutenberg.org

Hence, one boiler horse power is equal to an evaporation of 34.5 pounds of water per hour from and at 212 degrees Fahrenheit. The term boiler horse power, therefore, is clearly a measure of evaporation and not of power. A method of basing the horse power rating of a boiler adopted by boiler manufacturers is that of heating surfaces.
