The higher the level of excess combustion air, the lower the overall boiler efficiency due to 1) a reduction in the flame temperature, lowering radiated heat transfer from flame to boiler walls, and 2) higher gas volumes passing through the boiler, increasing the flue gas velocity, reducing gas residence time, and thereby reducing the convected heat transfer to the boiler walls.
