WebbExcessive excess air can cause carbon monoxide generation and reduced efficiency, and it can also disturb some types of flame- sensing technologies. Excessive excess air can increase the volume of the flue gases, which will increase their speed as they travel through the appliance’s heat exchanger. 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 ...
