The invention relates to a device for cooling a solid matter from a coal gasification, wherein said device comprises a container with a feed part, cooling part and venting part. Lines arranged transversal to the flow direction are located inside of the cooling part that are grouped in two kinds, wherein the one kind comprises liquid carrying lines and the other comprises gas carrying lines. The liquid carrying lines are closed in the interior of the cooling part and are provided for the heat exchange. The other kind comprises gas carrying lines that are gas permeable into the interior of the cooling part in such a way that solid matter comprising primarily cooled slag, ash and flue dust is cooled and the remaining gas present in and between the solid matter particles is exchanged. The invention also relates to a method for cooling down the solid matter and for removing the remaining gas from the particles. |
