Complete Combustion - an overview | ScienceDirect Topics

Notice that for each kg of fuel entering combustion, there is 16.7 kg of air required as a minimum! In reality, more air than this must be supplied, since some excess air is required to insure complete combustion.For natural gas, an efficient boiler would use about 15 percent excess air, or roughly 19 kg per kg of fuel.
