The hot gas line serves to conduct a product gas, which contains hydrogen and carbon monoxide and which is at temperatures in the range from 600 to 1500.degree.C. The hot gas line comprises an outer sheath tube, an inner protective tube, which is subdivided into sections, and a protective layer, which consists of a heat-insulating protective compound and is disposed between the protective tube and the sheath tube. At least one section of the protective tube comprises a compensator, which consists of metal bellows, which will take up the length change of the section of the protective tube.
