Air Fuel Ratio Effect on Combustion Efficiency

In most scenarios, a liquid and gas fuel burner achieves this desired balance by operating at 105% to 120% of the optimal theoretical air. For natural gas fired burners, the stoichiometric air required is 9.4-11 ft. 3 / 1.0 ft. 3 of natural gas, or approximately an air-to-gas ratio of approximately 10:1. This results in an excess oxygen level

Of course, this never happens, therefore burner combustion air fans may be sized for 25% excess air, in which case the fan would deliver 12.5 ft 3 of air per 1 ft 3 of natural gas
