So how exactly do we calculate the amount of natural gas used to burn natural gas boilers? 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 = calorific value÷(Calorific value of natural gas x Boiler thermal efficiency )= 2400 000 Kcal / (8500Kcal * 0.94)
24/03/2021 · Under normal conditions, the dew point for natural gas is around 57 degrees Celsius. Hence, in order for the boiler to work in condensing mode, the coolant temperature in the reverse loop should not exceed 57 degrees Celsius. If the above conditions are not reached, then the efficiency rate of the condensing boiler will decrease.

2. Fuel calorific value and price The calorific value of different types of fuels will also vary. The calorific value of natural gas combustion is 8600 kcal/m3, and the calorific value of diesel is 10240 kcal/kg. However, the cost of fuel should also be considered. comprehensive. 3. Boiler thermal efficiency The thermal efficiency of the boiler

25/06/2018 · CV calorific value of natural gas 38.76MJ/m 3 (1040 BTUs) 3.6 converts Mj into kW; Appliance Input (kW) = (3600/t) x 1040/3412
Gas rate = 3600/122 x 0.088 x 10.76 = 27.94kW gross, or 27.94/1.11 = 25.17kW net. The manual gives 24.49kW net maximum pretty close, but is the boiler slightly over-gassed (under is better than over)? If we stop at stage 2 above, we simply leave out the 10.76 figure: Gas flow rate = 3600/122 x 0.088 = 2.597m 3
