WebbThe amount of air supplied can be expressed alternatively as a percent excess or a percent deficiency of air. Thus, 150% of theoretical air is equivalent to 50% excess air, and 80% of theoretical air is the same as a 20% deficiency of air. For example, consider the complete combustion of methane with 150% theoretical air (50% excess air). The ...
