To provide a method and a device for waste disposal by a stoker furnace which performs DXN reduction and resource recovery by reforming main ash without raising the temperature of the stoker furnace in the waste disposal by the stoker furnace.
This device for waste disposal by the stoker furnace comprises: a hopper 11; a stoker 12; a primary combustion area 14 which forms a furnace body to cover the total upper area of the stoker 12; a secondary combustion area 15 which is provided above the primary combustion area and demarcates a molten exhaust gas flow passage downstream of the stoker in the primary combustion area from a combustion exhaust gas flow passage of the gasified gas upstream of the stoker via a bulkhead 16b; an ash-discharging chute 13 provided on an end of the stoker 12; primary heating air 17a to be blown into a most lower part from the upstream side to the downstream side of the stoker 12; and oxygen-enriched air 18 to be blown from the remaining lower part on the downstream side.
