• ### Combustion Efficiency and Excess Air

The combustion efficiency increases with increased excess air - until the heat loss in the excess air is larger than the heat provided by more efficient combustion. Typical excess air to achieve the highest possible efficiency for some common fuels: 5 - 10% for natural gas. 5 - 20% for fuel oil.

• ### How to Calculate the Gas Consumption of the Gas Fired Boiler?

It is known that the power of 1t/h gas fired boiler is 0.7MW assuming the low heat value of natural gas is 35MJ/m3 (the specific number can be detected) assuming that the minimum efficiency of the gas boiler is 92% and output is required. Then the natural gas consumption per hour: L= Q÷qL÷92%×3600 = 0.7÷35÷92%×3600 = 78.26m³/h. This makes it clear that to achieve the output heat of 1000kg/h boiler
