Definitions

  • Fuel-operated heaters with recuperators to increase efficiency are known from the prior art.
  • the exhaust gas of a heating burner which has been cooled in a first heat exchanger, further cooled by means of cold process water. While by means of heating water, the exhaust gas can be minimally cooled to the heating return temperature, the waste gas can be cooled down to a minimum of the temperature of the cold process water during process water cooling.
  • Heaters with recuperators are known from the prior art.
  • a conventional, wall-mounted heater can be supplemented by a recuperator, which is mounted between the heater and the wall, so that the heater is attached to the wall-mounted recuperator. This creates a compact unit with few attachment points on the wall.
  • the invention has for its object to provide a compact connection for a gas-fired heater with recuperator, by means of which existing installations can be used.
  • FIGS. 1 to 3 show from above, the side and from behind a fuel-fired heater 2, which is connected to its heater housing 3 to a recuperator 5 of a recuperator 4 via the recuperator front 10 via fastening means not shown in detail.
  • a fuel-fired heater 2 which is connected to its heater housing 3 to a recuperator 5 of a recuperator 4 via the recuperator front 10 via fastening means not shown in detail.
  • At the Rekuperator Wegwand 9 not shown in detail means are mounted on the wall.
  • the heater 2 has an upwardly directed Schuungsabgasrohran gleich 6, the recuperator 4 via an exhaust gas inlet 7 and an exhaust outlet 8.
  • An exhaust gas adapter 1 connects the Schuungsabgasrohran gleich 6 of the heater 2 with the exhaust gas inlet 7 of the recuperator 4 and the exhaust gas outlet 8 of the recuperator 4 with a Adapter exhaust pipe connection 11, wherein the direction of the mouth of the Edelungsabgasrohran gleiches 6 and the direction of the mouth of the AdapterabrohrrohranInstitutes 11 form a right angle and also lie in a plane perpendicular to the Rekuperatorschreibwand 9.
  • the exhaust gas adapter 1 which connects the heater exhaust pipe connection 6 with the exhaust gas inlet 7 of the recuperator 4 and the exhaust gas outlet 8 of the recuperator 4 with the adapter exhaust pipe connection 11 by means of exhaust pipes 12, surrounds - as in FIGS FIGS. 1 to 3 shown - this exhaust pipes 12 fresh air.
  • the exhaust adapter 1 connect the Schuungsabgasrohran gleich 6 with the exhaust gas inlet 7 of the recuperator 4 and the exhaust outlet 8 of the recuperator 4 with the adapter exhaust pipe 11 in coaxial lines, the exhaust pipes 12 are surrounded by fresh air ducts 13
  • the exhaust gas adapter 1 has the same extent as a standard exhaust gas bend from the inlet connectable to the heating exhaust gas pipe connection 6 to the adapter exhaust gas pipe connection 11. This ensures that standard exhaust pipes can be used to connect the combination of heater 2 and recuperator 4 use.
  • the exhaust adapter 1 has from the connectable to the Walkerungsabgasrohran gleich 6 entrance to the adapter exhaust pipe 11 over the same horizontal extent as the sum of the depth t of the Rekuperatorgeophuses 5, resulting from the distance between Rekuperator Wegwand 9 and Rekuperatorvorderseite 10, plus a standard exhaust bend.
  • a simple supplement is possible.
  • a mounted heater 2 can be dismantled, connected to the recuperator 4 and connected via the exhaust adapter 1 again with the existing exhaust pipe.
  • For a new installation standard components can be used.
  • the exhaust gases of the heating device 2 which have delivered thermal energy to a heating circuit in a primary heat exchanger, not shown, and thus minimized to heating return temperature, through the Schuungsabgasrohran gleich 6 via the exhaust adapter 1 in the exhaust gas inlet 7 of the recuperator 4.
  • the recuperator 4 are the exhaust gas in a heat exchanger, not shown, from further thermal energy to fresh hot water.
  • the hot water heated in this way flows out of the recuperator 4 to the heating device 2, where it is further heated to the set temperature in a conventional manner.
  • the thus further cooled exhaust gas flows from the exhaust gas outlet 8 of the recuperator 4 via the exhaust gas adapter 1 to the adapter exhaust pipe connection 11 and from there via a not shown exhaust pipe into the environment.
  • Fresh air flows from the coaxial exhaust pipe via the exhaust adapter 1 directly to the heater 2.
  • Fresh air flows in the variant according to FIGS. 4 and 5 Fresh air from the coaxial exhaust pipe via the exhaust adapter 1 first in the recuperator 4 and from there to the heater 2.
  • the last-mentioned variant provides an air jacket in the recuperator 4 for heat recovery of the heat losses of the recuperator 4 in the fresh air.
  • the principle is that the warmer medium can be minimally cooled to a temperature above the temperature of the colder medium, the maximum heat transfer is achieved in a countercurrent flow.
  • Exhaust gases of conventional natural gas powered heating burner 2 have a water vapor content of about 105 grams of water vapor per dry kilogram of exhaust gas. The dew point of the exhaust gas is around 55 ° C.
  • the outside air temperature is lower than the hot water temperature, so that in the recuperator heat can be transferred from the exhaust gas to the fresh air again. Since the exhaust gases in the heat exchanger of the heating device 2 are already cooled to a temperature well below 100 ° C, there is no risk of overheating in the recuperator 3, if it can no longer absorb heat.
