Mar 15, 2019 · With those measurements, the following formulas can be used to calculate excess air: For example, if the oxygen dry reading in flue gas is 2.5%, then the excess-air calculation would be: 0.895 x 0.025 / (0.21-0.025) = 12.1% excess air. Too much excess air leads to lower flame temperature. That means less heat gets into the system. Also, excess air must heat up to flue gas temperature, which …
