Zusammenfassung:An ash melting system of the present invention includes a slagging combustion furnace ( 10 ) for melting ash into molten slag; and a slag separating apparatus ( 50 ) for bringing the molten slag ( 121 ) discharged from the slagging combustion furnace into contact with slag cooling water ( 152 ) to produce water-quenched slag ( 122 ), and separating the water-quenched slag from the slag cooling water. The ash melting system further includes a gas blowing means for blowing air or inert gas ( 132 ) between a slag discharge port ( 14 ) of the slagging combustion furnace and the surface of the slag cooling water.
