Get A QuoteThe 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…
