At this time, multiple material conveying tanks 4 can move along the distribution trajectory of the conveying chain 3, so that the unmelted materials can enter from the top port of the smoke exhaust pipe 6 in turn, and then enter the gasification furnace 5. In this process, the high-temperature exhaust gas generated by the melting of the material in the gasification furnace 5 enters the interior of the smoke exhaust pipe 6, and then moves upward along the smoke exhaust pipe 6.
