Abstract

A heat exchanger for cooling synthesis gas generated in a coal-gasification plant has heat-transfer pipes (1) that the gas flows through, that are secured in two slabs (2 & 3) of piping, and that are enclosed in a jacket (4). The gas intake-end piping slab (2) is protected by a layer of ceramic flooring. The flooring consists of adjacent block-shaped sockets (12), each of which has an opening (15) that tapers together conically into a pipe section (14) that extends into one of the pipes (1).
