Definitions

  • the invention relates to a heat generator for hot water preparation and heating operation, consisting of an essentially cylindrical, vertical container with cold and hot water connections, with a heating flow and a heating return connection and with a heating device, formed from a fan burner-equipped, arranged in the container heating gas.
  • Heat generators of this type are known, for example, from DE-A-39 06 715.
  • heat generators of this type if they are not provided with an electrical heating device, are usually equipped with coils which are connected to the supply and return connections of a boiler and are placed near the boiler or are directly combined with it.
  • the tendency is on the one hand towards boilers with low output, on the other hand, one is becoming more and more demanding in terms of hot water preparation or provision of hot service water, i.e.
  • the actual heat input takes place and, with a comparatively relatively small heat transfer surface, is distributed relatively unfavorably via a pipe which is centrally penetrating the container and is equipped with a lintel burner and from which the heating gases, relatively poorly used, flow out immediately below.
  • the invention is therefore based on the object, and also taking into account the above-mentioned opposite tendency to create a compact and small-volume heat generator that can primarily fulfill the function of hot water preparation and maintenance, but on the other hand and therefore also the secondary Can take over the function of a boiler, which should be achievable with simple means by appropriate conversion of conventional heat generators, combined with the proviso that the heating gas duct should be provided with the largest possible heat transfer area.
  • a heat generator of the generic type according to the invention in that the heating gas guide from a part which extends vertically into the upper region of the container and from an adjoining part which is led out of the latter in the lower region and one with respect to the part having a substantially larger heat exchange surface is formed, with essentially the lower half of the vertical part being designed as a combustion chamber and in which the burner is arranged centrally and vertically upwards, and that in the upper region of the container above the two parts there is a heat-carrying heat exchanger with its heating feed and return connections led out of the upper region of the container.
  • the combustion chamber is formed from a part which is hemispherical in cross section and from an adjoining part which tapers upwards, and further the second part of the heating gas duct consists of a helically coiled line.
  • the heat exchanger is designed in the form of a pocket which is wound in a plane spiral, the diameter of which corresponds essentially to the inside diameter of the coil formed from the line.
  • the heat generator consists in a known manner of an essentially cylindrical, vertical container 1 with cold and hot water connections 2, 3, with a heating flow and a heating return connection 3, 4 and with a heating device, formed from a fan burner-equipped heating gas guide 5 arranged in the container 1 .
  • the heating gas guide 5 is made up of a part I which extends vertically into the upper region 1 'of the container 1 and from an adjoining part 1' of the container 1 in the lower region 1 '' formed in relation to Part I much larger heat exchange surface Part II.
  • the lower half H of part I forms the combustion chamber 6 and in this the burner 7 is arranged centrally and vertically upwards.
  • a heat exchanger 8 leading the heat transfer medium for the heater 10 with its from the upper area 1 'of the tank 1, the heating supply and return connections 3, 4.
  • the combustion chamber 6, as shown, is formed from a part 6 'which is hemispherical in cross-section and from an adjoining part 6' 'which tapers upwards, and the second part II of the heating gas guide 5 consists of a helically coiled line 9.
  • the largest diameter D of the part 6 'of the combustion chamber 6 corresponds essentially to the inner diameter D1 of the helix formed from the line 9.
  • the heat exchanger 8 is in the form of a (in plan view) plane-spiral wound pocket 8 ', the diameter D2 of which essentially corresponds to the inner diameter D1 of the coil formed from the line 9.
  • the heat exchanger 8 which is part of the heating circuit 11 equipped with a pump 12, seen in projection, covers the entire heating gas duct 5, the exhaust gas connection located in the lower region 1 ′′ of the container 1 in FIG. 1 is withdrawn from view.
