Abstract:
An apparatus for abatement of waste components comprising:a thermal oxidation apparatus sized and adapted to receive an amount of an oxygen component, a controlled amount of fresh air, a controlled amount of a fuel component, and an amount of a gaseous component to be thermally oxidized and to provide a location for the combustion of said oxygen component and said fuel component, at least the partial thermal oxidation of said gaseous component and the formation of a gaseous effluent; an abatement retention chamber, connected to said thermal oxidation apparatus, to which said gaseous effluent is passed and where said gaseous effluent is maintained at conditions effective to thermally oxidize said gaseous component, thereby producing an exhaust gas; said abatement retention chamber being capable of accepting secondary pollutants for incineration therein; a fuel control assembly to control the amount of fuel component passed to said thermal oxidation apparatus based on the temperature in said abatement retention chamber so as to maintain the temperature in said abatement retention chamber at at least a predetermined, minimum value; a Stirling cycle engine located downstream from said abatement retention chamber and to which said exhaust gas is passed; said engine being capable of further thermal oxidation of said exhaust gas and other secondary pollutants and generating a useful product; and a heat transfer assembly located so as to receive said exhaust gas to transfer heat from said exhaust gas, thereby generating a useful product.
