PROBLEM TO BE SOLVED: To provide a combustion control device and a combustion control method for a pyrolytic-gasification fusing furnace which controls the reduction combustion in an ash fusing furnace by directly operating an air ratio and a combustion ratio, and achieves good environment and cost reduction by reducing NOx and minimizing the use of auxiliary fuel. SOLUTION: This combustion control device 7 of the pyrolytic gasification fusing furnace 1 comprising a pyrolytic furnace 3 for thermally decomposing and gasifying wastes 2, the ash fusing furnace 4 mounted at a downstream side of the pyrolytic furnace 3, and a secondary combustion chamber 6 for combusting a waste gas 5 discharged from the ash fusing furnace 4, further comprises an operating device 28 for operating an air ratio and a combustion ratio of each of the pyrolytic furnace 3, the ash fusing furnace 4 and the secondary combustion chamber 6, and the air ratio of each of the ash fusing furnace 4 and the secondary combustion chamber 6 is controlled on the basis of a result of the operation by the operating device 28.
