Abstract
A cooler for gases generated from coal by gasification under pressure has a pressurized vessel (1) that accommodates an insert (5) with a polygonal cross-section made out of pipes (6) that are welded together gas-tight in conjunction with webs (7). The pipes in the insert are bent vertically in to create a roof (11) and parallel one another sector by sector with webs of uniform width. The pipes that abut at an angle at the edges of the sectors are united in pairs by forged crosstail butts (13). The crosstail butts are aligned along a straight line and completely occupy the spaces between the sectors.
