Definitions

  • the present invention relates to an exhaust gas heat exchanger according to the preamble of the claim.
  • Such an exhaust gas heat exchanger has become known from NL-A 7 612 508. From this citation, an exhaust gas heat exchanger emerges in which the exhaust gas flow follows a loop as it passes through the exhaust gas heat exchanger element, the beginning and end of the loop being at different levels. In this case, the outlet duct cuts through the inlet duct, heat being emitted directly between the inlet and outlet of the exhaust gas duct, this heat being lost in the exhaust gas heat exchanger.
  • an exhaust gas heat exchanger that can be inserted overhung into an exhaust pipe has become known and is surrounded by a bypass line.
  • An exhaust gas shut-off valve can be provided at the beginning of the bypass line or upstream of the heat exchanger element. Since the flow direction is not diverted during the passage of the entire exhaust gas heat exchanger for the exhaust gas, there is a counterflow for condensate and exhaust gas, which is detrimental to the heat utilization.
  • the present invention is based on the object of guiding the exhaust gas flow in such a way that a thermal separation between the inlet and outlet and a rectified flow between the exhaust gas and the condensate obtained is ensured.
  • the fan should be arranged so that a promotion of both the cooled by the heat exchanger element and the uncooled exhaust gas is possible.
  • the exhaust gas heat exchanger is an integrated device which is provided with an inlet 1 at the bottom and an outlet 2 at the top, the center axes of which are aligned with one another, for installation in a vertical exhaust gas line and which can be fastened as fastening elements in a set-up wall as a separate unit.
  • the exhaust gas heat exchanger is essentially made of sheet metal parts 5.
  • the exhaust gas heat exchanger is a so-called add-on unit that can be attached and attached to an existing heating boiler by means of feet 30.
  • an inlet space 16 is adjoined by the lateral inlet duct 15, the outer walls of which are provided with the heat insulation 7, which takes place laterally with respect to the outside atmosphere and with respect to the heat exchanger element 6.
  • the inlet duct 15 merges into a further space 31, to which the heat exchanger element 6 is directly connected, which is also protected on all sides by the insulation 7 from the surrounding spaces.
  • the space 31 is shielded from the outlet 2 by a beam wall 33 provided with holes 32. Downstream of the heat exchanger element, the outlet space 34 is provided, which is provided with the insulation 7 already mentioned in the direction of the inlet 1 to the exhaust gas heat exchanger.
  • the outlet space 34 is connected to the outlet 2 via an outlet channel 35, the outlet channel 35 is in turn connected to the heat exchanger element via insulation 7, but is non-insulated from the atmosphere, only by the sheet metal wall 5.
  • the impeller 19 is provided above the jet wall 33, the motor of which is not shown.
  • the outlet of the blower is directly connected to the outlet 2.
  • the entire exhaust gas coming from the heat source passes through the heat exchanger element 6.
  • the fan with the fan is arranged at the highest point of the heat exchanger, the fan is still heated via the jet wall 33 or by hot exhaust gas escaping there, so that the fan always runs in dry conditions so that signs of corrosion are largely avoided.
  • Inlet and outlet openings 1 and 2 are aligned so that the exhaust gas heat exchanger can easily be inserted into existing exhaust pipes by separating a correspondingly long piece from the exhaust pipes.
  • the exemplary embodiment has the advantage over the prior art that power crossings are avoided, so that optimum efficiency is largely achieved without undesirably cooled exhaust gas being heated up again behind the heat exchanger. It is possible to design the device both as a wall-mounted device and without a chimney connection, i.e.
  • the room 34 is designed so that the bottom floor forms a groove in which dripping condensate collects and can be discharged to the outside via a line. This ensures that the condensate can precipitate without exposure to hot, fresh exhaust gas.
