A vertical incinerator has three or more adjacent, stationary, heat-exchange sections which communicate, via respective plenums, with a common high-temperature combustion chamber positioned above them. Inlet and outlet valving to each heat-exchange section is provided and operated so that when effluent from an industrial process is fed upwardly through one of the sections to the combustion chamber, at least one other section is operating in an exhaust mode to withdraw the products of combustion downward through it thereby recapturing some of the generating heat. In order to prevent upwardly moving effluent from substantially short-circuiting the combustion chamber, each section is provided with a cover having an aperture which produces a jet effect. Thus, the relatively low velocity effluent stream from the industrial process applied through the aperture in the cover of the first section has its velocity increased, for example, 3-5 times as it enters the combustion chamber. The effluent moves in jet form toward the top of the combustion chamber causing some turbulent gas movement in the latter and insuring a prescribed minimum residence time for the effluent in that chamber.

In one embodiment, the incinerator has three or more aligned stationary, vertical adjacent structures, each of which has a heat-exchange section covered partially by respective plates which are so arranged as to provide between adjacent ones of the sections substantially uniform gas flow paths via a common combustion chamber disposed above all of the sections. In another embodiment, generally cylindrical vertical and aligned sections are provided, each having a heat-exchange bed supported on a perforated member. The level of the heat-exchange elements in each section is kept very low. The tops of the three sections communicate with one another via a generally horizontal, combustion passageway formed between them into which at least one burner is placed. All unprocessed effluents which proceed through and from the top of one bed to the top of an adjacent bed will have traversed paths at more uniform velocities and will have been subjected to high temperature processing substantially all along that path thereby preventing incomplete incineration.
