The invention relates to an incinerator. The incinerator comprises an incinerator body, a
combustion chamber arranged in the incinerator body, a feed port communicated with the
combustion chamber, and an exhaust port provided with an exhaust blower, wherein an exhaust channel which exchanges heat with a heated body is arranged in the portion, between the exhaust port and the
combustion chamber, inside the incinerator body. The incinerator is characterized in that the feed port is an air inlet and located above the
combustion chamber, the lower portion of the
combustion chamber is provided with a
smoke discharge port communicated with the exhaust channel, meanwhile, a combustion
bed which covers the
smoke discharge port is placed at the bottom of the
combustion chamber, the upper surface of the combustion bet is design into a grid, vent holes which are communicated with the
smoke discharge port are formed in two side faces, corresponding to the smoke discharge port, of the combustion
bed respectively, other side faces of the combustion
bed are closed, and therefore a combustion area above the grid and a smoke and dust discharge area below the grid are formed in the combustion chamber. By the adoption of the structure, the incinerator has the advantages that full combustion can be achieved, no
black smoke is produced,
firewood can be conveniently added, combustion is stable and controllable, and the smoke can be smoothly discharged.
