ABSTRACT:
A furnace afterburner consisting of an elongated combustion chamber through which the exhaust effluvia of a furnace is drawn, and in which a series of sets of air jet nozzles are arranged in longitudinally spaced relation along the chamber, which inject air tangentially into the chamber to generate vortices of air and exhaust spinning in alternately opposite angular directions. The injected air may be preheated. The central core area of the chamber is filled and obstructed to prevent inefficient combustion which would otherwise occur in the "eyes" of the vortices. Damper controls are provided to induce and reinforce other variations of conditions within the chamber, such as those capable of producing better retention time, better turbulence, air-gas mix proportions and temperature, all with the purpose of providing better combustion with a high degree of controllability in a wide variety of operating conditions.
