### Making sense of boiler ratings - HPAC Magazine

A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (hg - hf) m (1) where. W = boiler capacity (Btu/h, kW) hg = enthalpy steam (Btu/lb, kJ/kg) hf = enthalpy condensate (Btu/lb, kJ/kg) m = steam evaporated (lb/h, kg/s)
