Boiler Horsepower

A unit of measurement of the ability of a boiler to EVAPORATE WATER.

To evaporate 15.6 kg/hr or 34.5 lb/hr of water an hour.

1 Boiler Horsepower = 33,475 Btu/hr, 9.8 kW
                                      = 10 ft2 Heating Surface

500 hp = 500 x 34.5 lb/hr = 17,250 lb/hr
             = 500 x 15.6 kg/hr = 7,824 kg/hr
