    L.M. Grillo, in Waste to Energy Conversion Technology, 2013 6.3.4 Combustion air. Combustion air is injected into a furnace as underfire air (below the grate) and overfire air (into the flame above the grate). Generally, 50% to 70% of the total air is underfire air and the remaining portion is overfire air. Most mass burn furnaces operate with between 50% and 100% excess air.
