Abstract

The gasification device includes a pipe wall structure assembled of a plurality of pipe circuits enclosing in a gas tight manner a reactor space. A pressure jacket surrounds at a distance the pipe wall structure and delimits therewith a water filled interspace. All inlet conduits for supplying cooling water to individual pipe circuits pass through the jacket whereas the outlets of the pipe circuits open into the interspace. A common discharge conduit for cooling water is provided in the pressure jacket and communicates with the interspace. The pressure jacket is assembled of two parts interconnected by a releasable flange connection. All inlet conduits and common outlet conduits are attached to the upper part so as to enable the lifting of the entire pipe wall structure upon the lower part together with the upper part.
