Abstract

Process and apparatus for the preparation of synthesis gas by the partial combustion of a carbonaceous fuel with an oxygen-containing gas in a reactor also producing molten slag, the molten slag being removed through a slag discharge in the bottom portion of the reactor and being passed by gravity into a water bath where it is solidified by quenching. Solidified slag floating on the water of the water bath is removed therefrom by lowering the water level in the water bath to a location or point below the lower end of a baffle, the baffle being arranged in the water bath and dividing the water bath into an upper quenching zone and a lower capturing zone, and by raising the water level again to above the upper end of the baffle, thereby capturing floating slag under the baffle, the captured slag being discharged from the water bath through an outlet arranged at or near the top of the capturing zone.
