GASIFICATION SYSTEM AND ITS USE

A gasification system that comprises a gasification reactor and a synthesis gas cooling vessel, and its use. The gasification reactor comprises a pressure shell for maintaining a pressure higher than atmospheric pressure; a slag bath located in a lower part of the pressure shell; and a gasifier wall arranged inside the pressure shell. The gasifier wall defines a gasification chamber wherein during operation the synthesis gas can be formed, a lower open part of the gasifier wall which is in fluid communication with the slag bath and an open upper end of the gasifier wall which is in fluid communication with the synthesis gas cooling vessel via a connecting conduit. The synthesis gas cooling vessel comprises an inlet for hot synthesis gas; an outlet for cooled synthesis gas; and means to directly contact liquid water with the hot synthesis gas as formed in the gasification reactor in use.
