A ventless, combustible waste reduction process and apparatus which can utilize any type of combustion means for disposing of hazardous, as well as non-hazardous, burnable waste. Such wastes include toxic combustible liquids, oil slurries, soils contaminated with dioxin, PCBs, creosote, or any other potentially harmful or toxic combustible material. In particular, the present invention relates to a ventless, combustible waste reduction process in which the operating pressure is slightly below atmospheric pressure and which employs no venting or stack discharge of pollutants whatsoever. The entire flue gas stream is scrubbed, enriched with oxygen and recycled to the combustion chamber in varying amounts in response to pressure and temperature measurements taken in the combustion chamber to maintain the pressure and temperature in the combustion chamber within pre-selected ranges.

A process for combusting waste material comprising the steps of: (a) loading combustible waste into an air-tight combustion chamber where the waste is combusted; (b) passing a resulting flue gas stream from the combustion chamber to a heat reduction chamber where the temperature of the flue gas stream is reduced; (c) passing the flue gas stream from the heat reduction chamber to a heat exchanger where the temperature of the flue gas stream is further reduced; (d) passing the flue gas stream from the heat exchanger to a gas cleaning chamber where some acids contained within the flue gas stream are neutralized and particulates are removed; (e) enriching the flue gas stream from the cleaning chamber with oxygen; and (f) injecting the oxygen enriched flue gas stream into the combustion chamber in varying amounts in response to pressure and temperature measurements taken in the combustion chamber to maintain the pressure and temperature in the combustion chamber within pre-selected ranges.
