Air Fuel Ratio Effect on Combustion Efficiency - Sage Natural Gas

Combustion efficiency is dependent upon using the right amount of air to consume the fuel. In fuel-fired process heating, the largest source of energy loss is through the exhaust stack, which is why managing air flow is essential to combustion efficiency. When fuel burns in the presence of oxygen it is converted to carbon dioxide, water and heat.

Boiler Combustion | CleanBoiler.org

As a safety factor to assure complete combustion, boilers are fired with excess air. One of the factors influencing NOx formation in a boiler is the excess air levels. High excess air levels (>45%) may result in increased NOx formation because the excess nitrogen and oxygen in the combustion air entering the flame will combine to form thermal NOx.

Boiler/Burner Combustion Air Supply Requirements and Maintenance

A periodic boiler flue-gas analysis is the best indicator that an adequate supply of combustion air exists. This, and any necessary burner adjustments, should be performed by a trained technician with the proper equipment to measure the amount of excess oxygen and/or carbon dioxide and ppm of carbon monoxide.

The requirements are about 15 cubic feet of combustion air and 15 cubic feet of dilution air for every cubic foot of gas burned. Since a cubic foot of natural gas contains about one thousand BTUs, a furnace that fires at the rate of 120,000 BTUs per hour would use 120 cubic feet of gas if it fired constantly for 60 minutes.
