The improved incinerator is a concentric elongated tubular array, with an outer closed tubular housing or shell, an annular tubular heat exchanger in the form of a bundle of spaced open ended tubes inside the housing and spaced inwardly therefrom to define an annular air passageway therebetween and front and rear spaces, and a tubular combustion chamber having an open front end and an open rear end. The front end thereof is necked down and in the form of a small diameter tubular inlet immediately downstream of the combustion zone in the combustion chamber. A fuel line, a fluidized waste material line and an ignition system pass through the inlet into the combustion zone, along with heated air to initiate and maintain the desired complete combustion of the waste material. The air is preheated by blowing it into the passageway and around and over the heat exchange tubes, before passing it into the combustion zone. The waste gases exit the housing through an exhaust stack at the front of the incinerator, which stack can be in heat exchange with the blower duct, in order to also heat the air and cool the exhaust gases. The incinerator operates, in accordance with the present method, with improved efficiency, requiring less fuel and producing fewer exhaust gases.

An improved incinerator for hazardous and other waste materials, said incinerator comprising, in combination: (a) a generally tubular elongated, outer housing having a sidewall, a closed front end, and an opposite closed rear end; (b) a generally tubular elongated heat exchanger open at opposite front and rear ends, releasably disposed in said outer housing and spaced inwardly from said housing sidewall and end walls to provide an annular air passageway therebetween and front and rear spaces; (c) a generally tubular combustion chamber releasably disposed within said heat exchanger, said combustion chamber being open at opposite front and rear ends thereof, including a narrow diameter front inlet end extending into said front space, and a combustion zone therein adjacent to said inlet end, said housing heat exchanger and combustion chamber being concentric; (d) a fluidized waste material supply line connected to said housing and passing into said combustion zone through said inlet end; (e) at least one fuel line and a fuel ignition device connected to said housing and passing into said combustion zone through said inlet; (f) air blower means connected to the front portion of said housing for forcing air into said annular passageway and over and around said heat exchanger and thereafter in a heated condition to and through said front inlet end to said combustion zone, for efficient combustion of fluidized waste therein, exhaust gases from said combustion passing into the rear end of said heat exchanger and forwardly therethrough to the front end thereof; and, (g) exhaust gas exit means connected to said front portion of said housing for passing exhaust gases from said incinerator.
