The BTU/hour to Boiler Horsepower calculator is used to help size both steam and hot water boilers. This calculation translates the heat transfer input requirement to BHP. To 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

A natural gas burner rated at 40,000 BTUs per hour divided by 1,000 BTUs per cubic foot uses approximately 40 cubic feet of natural gas in one hour. Exact Gas Consumption Step 1 Multiply the burner efficiency by the energy content of the gas being used. Natural gas contains 1,075 BTUs per cubic foot; propane contains 2570 BTUs per cubic foot. Step 2

The boiler gas consumption calculation need the following parameters: such as natural gas calorific value 8500kcal/m3, pressure 8-10Kpa, and theoretically, the gas consumption of boiler heat = boiler calorific value÷(Calorific value of natural gas x Boiler thermal efficiency )= 2400 000 Kcal / (8500Kcal * 0.94) =297m3/h, here we take 4 tons of
