PURPOSE:To stably and continuously carry out combustion without pelletizing the woody wastes by using a gasification-gas combustion system due to internal heating dry distillation. CONSTITUTION:A storage tank 2 provided with a material charging port 13 is stacked on a lower tank 1 provided with an ash take-out port 9, and a cylindrical stoker 3 provided with swash plates 17 formed in a spaced relationship across its entire periphery, is rotably disposed on the bordery region between the storage tank 2 and the lower tank 1, and an air supply port 4 is provided on the side of the cylindrical stoker 3, woody pulverized substances being successively dried and gasified by the radiation heat from the cylindrical stoker 3 and the peripheral side thereof while they are being piled up through the swash plates 17 of the cylindrical stoker 3 in the stationary state. Thereafter, the dry distilled gas is caused to flow into the cylindrical stoker 3 heat-accumulated and highly heated though the swash plates 17 together with supply air from the air supply port 4, whereby the distilled gas is completely burnt and subjected to heat decomposition and the cylindrical stoker 3 is rotated to thereby remove ash, and agitate and move the unburnt pulverulent. |
