The wood gases of a facility for the carbonization of wood to produce a lump charcoal are passed to an afterburner. The afterburner utilizes auxiliary burner units set at an angle to the combustion chamber centerline to provide heat for increasing the temperature of the refractory liner to the combustion level. Combustion air is introduced into the chamber resulting in a rapid mixing of the air with the gas. As a result of the introduction of the combustion air, a cyclonic movement of the flame occurs resulting in continuous contact between the gas and the hot refractory during its passage through the combustion chamber. The burned wood gases are maintained at a predetermined temperature by mixture with ambient air and supplied directly for an end use comprising lumber drying kilns. The burned wood gases are thus capable of economically drying southern pine lumber to 20% moisture content in one-fifth the time required by natural air drying.
