A heat exchanger for transferring heat from exhaust gasses to incoming burn air has a rotating design (5) with gas ducts parallel to the rotation axis and positioned between a hot cover (3) and a cooled cover (4). The exhaust flow (100) is from the hot cover through the ducts and out of the cooled cover, with the burn gas flow parallel but in the opposite directions. The rotating heat exchanger is fitted into a cylindrical housing which is thermally isolated from the covers by ring seals (13, 14) and by central seals (18, 19) between the rotor axis and the covers. The sealing ring include cooling ducts through which cooling air is blown, to prevent thermal distortion of the system. |
