Abstract (en)
[origin: US4694897A] A heat exchanger for heat exchange between a hot gas and a flowing medium that is conveyed in tube bundle heat transfer surfaces, especially a steam generator. The heat exchanger includes a pressure tank, the heat exchanger vessel in which are disposed tube bundles, and a hot gas conduit that is connected with a gas inlet of the heat exchanger wall. Also included are a gas guidance tube, a gas outlet to a circulation fan, and inlets and outlets for the flowing medium. The gas guiding tube opens into the heat exchanger from the side, and an annular channel is disposed after the gas inlet in the heat exchanger wall. The annular channel is delimited inwardly by a riser that forms the gas outlet and is disposed concentrically relative to the walls of the pressure tank and the heat exchanger. The gas from this annular chamber enters the tube bundles and, after being deflected, enters the riser that leads to the circulation fan. The riser extends from the annular chamber in the direction of the tube bundles to the outlet ends of the latter.
