ABSTRACT:
An incinerator/combustor, comprising an elongated combustion chamber surrounded by an afterburner which is in turn surrounded by a housing, the afterburner and housing being coaxial with, and cooperating to provide redundant heating for, the combustion chamber, is disclosed. The combustion chamber is generally cylindrical with a horizontal axis, one end being adapted to receive materials to be burned. An ash chamber is spaced from the other end of the combustion chamber to define a circumferential opening which serves as an exhaust outlet. The two chambers are relatively movable to permit the flow of exhaust gases to be controlled. Air under controlled pressure is introduced to the combustion chamber to produce a cyclonic flow to enhance burning. A fuel supply may be provided to initiate combustion, but the system is designed to require no fuel other than the material being incinerated during normal continuous operation.
The afterburner extends over both the exhaust outlet and a major portion of the combustion chamber. Air under pressure directed across the exhaust outlet produces a Venturi effect to draw exhaust gases out of the combustion chamber and direct them into the afterburner. The outer housing receives exhaust gases from the afterburner and directs them back over the outside surface of the afterburner in a second redundant flow, carrying them to an outlet stack.
