ABSTRACT:
An exhaust gas treatment unit of the combustion type is capable of effectively carrying out the decomposing treatment of an exhaust gas while at the same time allowing the unit to be reduced in size. The exhaust gas treatment unit includes a treatment drum, a combustion air introduction tube attached at one end of the treatment drum to introduce combustion air to the inside of the treatment drum, a fuel gas introduction tube disposed inside the combustion air introduction tube to introduce fuel gas to the inside of the treatment drum, and an exhaust gas introduction tube disposed inside the fuel gas introduction tube to introduce exhaust gas to the inside of the treatment drum. A flame tube extends from an end portion of the combustion air introduction tube on the air outlet side to the vicinity of the other end of the treatment drum, and a cooling air introduction port is provided for introducing cooling air into a space between the side wall of the treatment drum and the flame tube. By virtue of the presence of the flame tube, the fuel gas flame is kept for a longer period of time, thereby improving its contact efficiency with the exhaust gas.
