To provide a waste gasification melting system capable of completing temperature raising of the system in a short time and reducing the use of fuel excluding wastes.
This thermal decomposition gasification melting system includes a fluidized bed-type thermal decomposition gasification furnace 3 for thermally decomposing wastes, a swivel melting furnace 6 connected with the thermal decomposition gasification furnace 3 through a pyrolysis gas flow channel 5, and burning the pyrolysis gas and char produced in the thermal decomposition gasification furnace 3 to obtain a high-temperature field to melt ash in the char, and an auxiliary fuel supply pipe 21 for supplying auxiliary fuel to the pyrolysis gas flow channel 5. The pyrolysis gas flow channel 5 can be cooled by switching a water-cooling mode and an air-cooling mode.
