Abstract (en)
[origin: US5088551A] A heat exchanger for cooling hot reaction gas with a coolant. It rests on a gas-supply compartment (4) and has gas-conveying pipes (9) inside a jacket (1). It is separated from the gas-supply compartment by a tube sheet (6) that accommodates the gas-conveying pipes (9). The pipes extend loosely through the tube sheet, leaving annular gaps (10) and are connected tightly to the tube sheet on the side where the gas enters. The heat exchanger has at least one line (12) for supplying coolant to the side of the tube sheet that faces away from where the gas enters. The diameter of the tube sheet is shorter than that of the jacket. The tube sheet is connected to the lower edge of the jacket by way of an upward-tapering cone (7). The tube sheet is provided with cooling channels (15) that are open at least at one end and communicate with the lines that supply the coolant.
