The cooling of cracked gas is served by a heat exchanger having a tube bundle held between two tube plates (2), and two terminal chambers (4) which adjoin the tube plates (2) and narrow to form a socket (5).

The rings (7) are arranged at a distance from the tube plate (2) in an extension of the socket (5) on the inlet side, and preferably along the surface of a cone pointing with the apex towards the gas inlet, on a surface which essentially corresponds to the cross-sectional surface of this socket (5). …IMAGE…
