ABSTRACT:
A distillation type incinerator generates gas containing much combustible gas owing to restricted air introduction at feeding the combustible matters thereto and minimum necessary supply of air for combustion and dry distillation, and generates residue which contains less unburned matters and can be taken out in lumps, so as to reduce the amount of waste and facilitate the recycle of useful metals. The dry distillation type incinerator comprises a feeding tower which is composed of a hopper and a body, the hopper composed of an inlet and a conveyor, the body which is composed of plural dampers, an inclined multistage furnace integrated with the feeding tower, the inclined multistage furnace composed of a first stage chamber, a middle stage chamber and a last stage chamber which are gradually inclined forward in the descending order, characterized in that a first gage is provided between the last stage chamber and the middle stage chamber and a second gate is provided at a discharge port of the last stage chamber, each chamber has furnace floor, which is inclined proportionally to the inclination of each chamber, and pushers which are provided for raking out unburned matters or residue along the inclined furnaces, the first stage chamber has an exhaust pipe fixed to an upper end thereof for exhausting a combustion gas, the second stage chamber has an air inlet for introducing air thereinto, the third stage chamber has an air inlet and a smoke duct for discharging the combusting gas.
