### Boiler Capacity Calculation with Heating Surface Area--ZBG

The commonly used calculation formula is: hot water boiler load D MW = T * S / 215000 which T for indoor and outdoor temperature difference S for heating area 215000 for the set heating equivalent.

To do so we divide the BTU/hour by a constant of 33475. This constant represents water being converted to steam which is 34.5 pounds of water multiplied by 970.3 BTU/lb or latent energy. For this calculation you will enter the BTU/hr of your operation along with the efficiency of your boiler.

Nov 02 2017 · hg = enthalpy steam (Btu/lb) hf = enthalpy condensate (Btu/lb) m = steam evaporated (lb/h) Calculate the boiler capacity for example: Boiler capacity = Burner capacity * efficiency. Example: efficiency = 95% & Burner capacity =11110 kW. boiler capacity =11110 kW * 0.95. ~=10500 kW.

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