The combustion gas at temperatures in the range from about 1000 to 1800°C comes from the combustion chamber of a Claus process plant and immediately after the combustion chamber is conducted through an indirect heat exchanger. The first section of the indirect heat exchanger comprises numerous narrow tubes, which have a small diameter d from 5 to 50 mm and are flown through by the combustion gas. In the tubes of the first section the combustion gas is cooled to a temperature which is not in excess of 800°C within a residence time which is not in excess of 0.05 second. A succeeding second section of the heat exchanger comprises tubes which have a diameter D which is at least 2d.
