ABSTRACT:
A fume incinerator having a rotary heat exchanger with a novel seal structure therefor. A rotating rotary heat exchanger wheel is positioned in the mouth of a tubular incinerator having a closed end wall opposite to the rotary heat exchanger. A baffle extends from the heat exchanger wheel to a point spaced from the closed end of the incinerator so that the fume and air mixture, after passing through one side of the heat exchanger wheel, is passed through one side of the incinerator wherein it is heated to a temperature sufficient to oxidize the fumes in the mixture, passes around the end of the baffle to the other side of the incinerator and through the other side of the heat exchanger wheel. The fume and air mixture is preheated from the heat of combustion as it passes through the heat exchanger wheel. The heat exchanger wheel is axially tapered and a seal member surrounding the heat exchanger is likewise tapered in a complementary manner. The rotary heat exchanger wheel is adjustably mounted on its axis of rotation so that the gap between the circumferential surface of the wheel and the seal member is adjustable. The heat exchanger wheel is made from a thermally stable ceramic material and the seal member surrounding the heat exchanger wheel is made from a thermally stable ceramic material having temperature expansion characteristics similar to that of the heat exchanger wheel.
