Drake, D E

A system is described for the combustion of waste products for the extraction of heat energy in a clean pollutant-free medium. The system includes a swirling air-cyclonic type incinerator having means for controllably consuming fuel in the form of waste products of various grades and heating values. Incinerator outlet means are provided for transmitting gaseous combustion products to a heat exchanger, a filtering device, and ultimately to a point of beneficial utilization. Through a plurality of ducts, control valves, and pumping means, a selectably variable volume of oxygen necessary to support combustion is taken from the ambient. The remaining gas flow to the incinerator for such purposes as creation of a swirling flow and cooling is pumped from the outlet side of the heat exchanger. By thus recirculating and utilizing the oxygen depleted exhaust products for incinerator functions in lieu of ambient air, the noted functions may be obtained without adding energy to heat the ambient air and without increasing the mass flow in the overall system. The temperature extant at the outlet of the incinerator may be readily controlled and the oxygen content of the combustion supporting gases may be directly regulated in accordance with the specific requirements of the particular fuel being burned.
