  Steam Boiler Capacity Calculation--Zozen

  W = boiler capacity (Btu/h) 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 =11,110 kW. boiler capacity =11,110 kW * 0.95. ~=10,500 kW.

  Boiler Sizing Calculators | Powerhouse

  Each boiler is given a boiler horsepower (BHP) rating based on the steam output capacity at 212°F and 0 psig. For this calculation, you will enter the steam load in pounds per hour, which will be divided by a constant of 34.5. This number represents the thermal energy rate required to turn 34.5 lbs of water at 212 °F to steam in one hour.

  Pressurised Deaerators | Spirax Sarco

  Steam flowrate to the deaerator (m_dot - body text.jpgs) has already been calculated at 334 kg/h. In this example the maximum water flowrate (the ‘actual’ capacity of the boiler) to the deaerator is 9 311 kg/h. Water valves are sized on volume flowrates, so it is necessary to convert the mass flow of 9 311 kg/h to volumetric flow in m3/ h.
