Definitions

  • the invention relates to a heating device with a burner arranged in a combustion chamber having a double jacket and provided with a flue gas discharge and a lamella heat exchanger, the double jacket of the combustion chamber having an outwardly directed flange and the lamella heat exchanger in a rotating, congruent with the inner wall or the inner walls of the double jacket formed jacket is held, which is provided with flanges with which the jacket is connected to the double jacket and the flue gas outlet.
  • EP-OS 315 577 it is also known to provide a double-walled combustion chamber with a circumferential flange on which a heat exchanger bracket, which also has a flange, is mounted.
  • the two flanges lie snugly on top of one another and are connected to one another in a conventional manner by means of a complex weld seam or conventional fastening bolts.
  • the main disadvantage here is a remaining residual uncertainty with regard to the tightness of the connection despite considerable installation effort.
  • the aim of the invention is to avoid these disadvantages and to propose a heating device of the type mentioned at the outset, which is distinguished by a simple structure in which there are no problems with the mounting of the fin heat exchanger.
  • this is achieved in that the flanges of the jacket are connected to the flanges of the double jacket by squeezing tooth-like sections of the flanges which are separated from one another by cuts in the outer edge regions, the tooth-like sections being bent out of the parting plane of the flanges.
  • bushings through the double jacket of the combustion chamber for holding the fin heat exchanger are unnecessary.
  • the bushings can be designed and manufactured much easier in the jacket of the finned heat exchanger than in the double jacket of the combustion chamber, as was the case with a previous solution.
  • there is a very easy to produce connection of the double jacket with the finned heat exchanger which can be produced with little manufacturing effort.
  • the mutually adjacent sections of the flanges which are poisoned with one another are bent out of the parting plane of the flanges in opposite directions.
  • a metal seal is interposed between the flanges of the combustion chamber and the jacket of the finned heat exchanger.
  • a circumferential groove is incorporated in the contact surface of the flange of the flue gas outlet, which groove serves to accommodate a seal.
  • the heating device according to FIG. 1 has a combustion chamber 1, which is surrounded by a double jacket 2, through which a medium to be heated, mostly water, flows. At its end faces, the double jacket 2 is provided with flanges 3 which protrude outwards.
  • a hood 5 At the upper end of the combustion chamber 1 there is a hood 5, likewise having a flange 4, in which a burner 6 is held.
  • This hood is provided on one end face with a nozzle 7, which serves to supply a combustible mixture.
  • a circumferential groove 8 is incorporated in the flange 4, in which an elastically deformable seal 9 is inserted.
  • the flanges 4 and 3 of the hood 5 or the double jacket 2 can be connected in the usual manner by means of screws and nuts passing through the flanges or produced by clamping.
  • the double jacket 2 also has a flange 3 against which a flange 10 of a jacket 11 abuts, in which is held a fin heat exchanger 12.
  • This jacket has a clear cross section corresponding to the clear cross section of the double jacket 2.
  • the feed and discharge lines 13, 14 penetrate opposite walls of the jacket 11.
  • a metallic seal (not shown) is interposed between the flanges 3 and 10, the service life of which is essentially designed for the service life of the entire heating device.
  • the connection of the two flanges 3 and 10 is designed to be operationally inseparable. This connection takes place in such a way that congruent cuts 18 are arranged in the edges of the flanges 3 and 10, which separate different sections 15, 16 from one another.
  • the individual sections 15, 16 of the flanges 3, 10 are potted together, at least one of these sections 15, 16 being bent out of the parting plane of the flanges 3, 10, as can be seen from FIG. 3. In principle, it is also possible to bend the sections 15, 16 in opposite directions from the parting plane of the flanges 3, 10.
  • a flange 4 of a flue gas outlet 17 On the lower flange 10 of the jacket 11, there is a flange 4 of a flue gas outlet 17. It is in the flange 4 of the flue gas 17 as well as in the flange 4 of the hood 5, a groove 8 for receiving a seal 9 is provided, wherein the connection of the flanges 10 and 4 can also be made by means of screws and nuts.
