    How to calculate steam boiler capacity?-Zozen Boiler

    Boiler capacity = Burner capacity * efficiency Example: efficiency = 90% & Burner capacity =11,110 kW. → boiler capacity =11,110 kW * 0.9 ~=10,000 kW. Why is boiler capacity given in ton per hour? It is sometimes difficult to understand boiler capacity terminology because not all manufacturers stick to norms when advertising boiler capacities.

    Sizing a Steam Boiler | U.S. Boiler Company

    Dec 05, 2017· Unlike a hot water boiler, a steam boiler is sized by determining the square foot of radiation connected to the steam system. Once that’s been determined, you can accurately select a boiler that’s large enough to heat the connected load (radiation). You only need enough steam to fill the system; any more could result in short cycling.

    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.
