Read MoreA 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)

Read MoreTo do so, we divide the BTU/hour by a constant of 33,475. 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.

Read MoreThe enthalpies can be taken from tables: m& AIR φ APH = m& FUEL ⋅ ⋅ (hAPH 2 − hAPH 1 ) (8) m& FUEL m& AIR where m& FUEL is the mass flow rate of fuel fed into the boiler [kg/s], the mass flow rate of m& FUEL combustion air divided by the mass flow rate of fuel fed into the boiler, h APH 1 the specific enthalpy of combustion air before

Read MoreFeb 12, 2021 · 4-A Coal fired boiler having total heating surface area 5200 M2 produces 18 kg of steam per square meter per hour of heating surface, then calculate the Boiler capacity in TPH. Boiler Capacity = (Heating g surface area X Steam generation per square meter) Boiler Capacity = 5200 X 18 = 93600 kg/hr =93600 / 1000 = 93.6 TPH

Read MoreBoiler horsepower - a power unit from the 19 th-20 th centuries - was used to rate the capacity of a boiler to deliver steam to steam engines.. A common definition of one boiler horsepower is the amount of energy required to produce 34.5 pounds (15.65 kg) of steam per hour at pressure and temperature 0 psig (0 bar) and 212 o F (100 o C) - with feed water at pressure 0 psig and temperature 212 o F.
