ABSTRACT:
An improved stack construction for an incinerator. A layer of refractory material is disposed on the inner surface of the stack and an elongated tubular member is positioned longitudinally within the stack and spaced from the layer of refractory material to provide an annular passage therebetween. An air supply conduit is connected to one end of the tubular member, while the opposite end of the tubular member is closed. The tubular member is provided with a plurality of outlet ports disposed along a length of the tubular member with the outlet ports facing laterally outward and downwardly to direct air toward the refractory liner and in contact with the waste gases passing upwardly through the annular passage to thereby increase the turbulence of the waste gases and provide an increased efficiency of combustion.
