1. 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.
