What is the Air Fuel Ratio Effect on Combustion Efficiency?

Feb 13, 2020 · Simply put, an air-to-fuel ratio is the measure of air compared to fuel involved in the combustion process. For safety reasons, knowing what the air-to-fuel ratio curve is on your burner system is critical. This curve measures the lowest amount of excess air that can be in the flue gas without producing carbon monoxide.

Proper maintenance includes keeping the air/fuel ratio at the manufacturer's specified setting, having the proper air and fuel pressures at the burner, and maintaining the atomizing air pressure on oil burners at the correct levels. An improperly maintained boiler/burner package can result in VOC levels over 100 times the normal levels.

Combustion Air Requirements For Oil Burners | Beckett Corp.

When combustion is deprived of the necessary oxygen, the correct ratio between the air and fuel changes to a fuel-rich, air-lean ratio. This causes an oil flame to become bright, orange, and soot-producing. In the case of a tightly sealed building, a burner which is operating cleanly might generate smoke as soon as another air using appliance
