A heat exchanger, in particular for use in the contact group of a sulfuric acid plant, includes a chamber (2) in which a tube bundle (12) is arranged on a circular ring, wherein between the tube bundle (12) and a chamber casing (13) surrounding the tube bundle (12) a gas space (15) is formed, a gas supply opening (6) provided in the chamber casing (13) for introducing a gas into the gas space (15) substantially radially relative to the tube bundle (12), and a gas outlet opening which adjoins an interior space (16) enclosed by the tube bundle (12) in substantially axial direction. A uniform approach flow of the tube bundle (12) is achieved in that the center (ZR) of the tube bundle (12) is offset with respect to the center (ZK) of the chamber casing (13) in a direction opposite to the gas supply opening (6). |
