Abstract Apparatus for incinerating waste gas which includes a hollow outer shell having a hollow inner liner supported therein so that an air passageway is formed therebetween. Front and rear walls are provided secured to the outer shell, and an intermediate wall having an opening disposed therein is secured within the outer shell. An air inlet is formed in the outer shell adjacent to the forward end thereof for admitting combustion air into the air passageway and means for injecting fuel gas into the outer shell at a position between the rearward end of the inner liner and the intermediate wall are provided. A waste gas inlet is formed in the outer shell for admitting waste gas thereto between the rear wall and the intermediate wall.
The apparatus of claim 1 wherein the inner liner includes a frusto-conical section converging toward the rearward end thereof and a frusto-conical section converging toward the forward end thereof, and wherein the outer shell is defined further as being shaped such that the inner liner and outer shell are coaxially positioned.
