<p>A gasification and slagging combustion system comprises a gasification furnace (2) for gasifying wastes at a relatively low temperature, and a slagging combustion furnace (7) for combusting a gas and char produced by the gasification furnace (2) at a high temperature. The slagging combustion furnace (7) comprises combustion chambers (8, 9, 10) for combusting a gas produced by the gasification furnace (2) at a high temperature. A slag discharge port (11) is provided at a bottom portion (91) of the combustion chamber (9) for discharging molten slag produced by combustion at a high temperature. An introducing groove (93) is provided at the bottom portion (91) of the combustion chamber (9) for introducing the molten slag flowing downwardly on the bottom portion (91) into the slag discharge port (11). The introducing groove (93) has a passage which is reduced in width gradually from the upstream side of the bottom portion (91) toward the slag discharge port (11).</p> |
