PROBLEM TO BE SOLVED: To uniformize a flow of gas generated in a grate part and a pyrolysis residue melting part in a waste filling layer formed within a drying shaft part. SOLUTION: Gas generated in the grate part for generating pyrolysis residue and the pyrolysis residue melting part 3 for melting the pyrolysis residue by using a massive carbon-based combustible substance as a heat source is made to pass through the waste filling layer 6 formed by charging waste from a top of the drying shaft part 1 for drying and pyrolyzing the waste, to dry and pyrolyze the waste. The gas passed through the waste filling layer 6 is discharged from the top of the drying shaft part 1, and the waste dried and pyrolyzed in the drying shaft part 1 is pyrolyzed in the grate part 2 to generate pyrolysis residue. The generated pyrolysis residue is supplied from the grate part 2 to the pyrolysis residue melting part 3 and is melted. The flow of gas in the drying shaft part 1 is detected, and the air blowing amount, air blowing temperature, air blowing balance and/or grate speed of the grate part 2 is changed.
