PURPOSE:To provide the title apparatus capable of stably and continuously discharging a slag without affecting operating conditions of a gasifying oven and gasifying performance, by incorporating a heater in a molten slag discharging portion in a spouted bed coal gasifying oven. CONSTITUTION:A spouted bed coal gasifying oven in which a coal and a gasifying agent are fed into a gasifying oven 1 to form a gas by gasification while an ash produced is molten in a high-temp. atmosphere to form a molten slag 5 which is in turn discharged into the outside of the furnace 1, characterized in that the furnace 1 is equipped with a slag hole 12 at the bottom thereof the outer side of which is surrounded by a water-cooled wall 2 branched from the end of a water-cooled wall inlet tube 15 and to which a fireproofing material 11 and a refractory and thermal insulating material 13 are applied and that a heater 14 is incorporated in the refractory and thermal insulating material 13. The above slag discharging apparatus can prevent the slag from being cooled and solidified without affecting operating conditions of the gasifying oven 1 and gasification performance.
