<p>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. In order to prevent upwardly moving effluent through one heat-exchange section from substantially short-circuiting the combustion chamber and going rapidly down through an adjacent heat-exchange section, 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. Thus its noxious components will have been thoroughly oxidized before they are sucked out through a second section operating in the exhaust mode.</p> |
