Abstract: A controlled thermal oxidation process for solid combustible waste. The process comprises a first combustion stage wherein the waste is burned in a downward direction from top to bottom. A first, fixed air flow of predetermined volume is passed from bottom to top of the waste. A second, modulated air flow of predetermined lesser volume is passed over the waste and through the combustion flame. The process further comprises a second combustion stage wherein products of combustion from the first stage are exposed to high temperature conditions for a short period of time under 135% to 200% overall stoichiometric air conditions.
