Definitions

  • the invention relates to a wall heater for combustion liquid fuels, consisting of a the exhaust gases for exhaust gas extraction leading housing in which a burner arranged with its axis horizontally oriented combustion chamber is that of a while forming a flow gap helically coiled, with flow and return connections hydraulically connected pipe as a heat exchanger is limited and by a rear wall, the Combustion chamber closed with a cover receiving the burner is.
  • Heaters of this type are, for example, according to FR-A-2 700 608 or also known from DE-A-199 12 572 A1, which are but not wall heating devices.
  • the highly effective heat transfer principle on which these heaters are based according to which the heating gases through the narrow flow gap of coiled heat exchanger to the flue gas outlet, however, as far as known, but not documented, also already used on wall heaters on the market, So especially for an installation in the living area provided on a wall and usually on the installation grid of Built-in furniture is parked, which is possible from the outset compact design of such devices.
  • the aforementioned wall heaters already on the market with a coiled heat exchanger correspond essentially the heater according to FR-A-2 700 608, i.e. the heating gases flow through here only as a continuous flow heater acting heat exchanger coil and arrive without essential further heat emission possibility via the heat exchanger surrounding Collecting room directly to the exhaust fume hood, which is the heat exchanger forming, coiled tube (usually has one flat-rectangular cross-section) with its ends directly the Forms flow and return connections of such a device.
  • This is disadvantageous due to the relatively low flow volume of the heat exchanger inevitably with it connected switching frequency of the burner, what with consideration accepted the installation of such devices in the living area had to become. You probably saw the compactness to be striven for such devices so far as an obstacle, such, coiled Wall units using heat exchangers with an additional volume to train for the heat transfer medium.
  • the invention has for its object while maintaining the most compact design possible improve that a larger volume of water with a larger overall Heat exchange surface is available and thus the Switching frequency of the burner for liquid fuels reduced is ultimately the same with every burner start counter associated, increased pollutant emissions.
  • the wall heater for burning liquid fuels still consists of a the exhaust gases to the exhaust gas exhaust 2 leading housing 1, in which a populated with burner 3, with their axis A horizontally oriented combustion chamber 10 is arranged is.
  • the combustion chamber is one with the formation of one Flow gap 4 helically coiled, with pre-and Return connections 5, 6 are in hydraulic connection Tube 7 limited as a heat exchanger WT.
  • the combustion chamber 10 bounded to the rear by a rear wall 8 and is closed at the front with a cover 9 receiving the burner 3, which of course can be opened in a suitable manner or to decrease.
  • FIG. 1 For such a wall heater, reference is now made to FIG. 1 essential that the coiled, connected to the return 6 Tube 7 with its leading end 11 in a the exhaust gases leading housing 1 surrounding, provided with the flow connection 5, water-bearing housing 12 opens out.
  • This water-bearing Housing 12 also forms the rear wall 8 of the Combustion chamber 10 and is exhaust gas exhaust 2 penetrated.
  • the volume the size of the housing 12 corresponds preferably about twice the volume of the heat exchanger WT.
  • the one Rear wall 8 of the combustion chamber 10 forming part of the housing 12, 1 also in the form of a volume the combustion chamber 10 enlarging dome 14, whose Diameter D essentially the inner diameter D1 Combustion chamber 10 corresponds.
  • This is so-called cathedral 14 dimensioned with a depth T that a complete burnout
  • the flame guarantees a precise and concrete in this regard Requirement, for example in relation to the length L of the combustion chamber 10 understandably not possible.
  • the representation of the ratio depth T to length L in 1 serve.
  • the two housings 1, 12 advantageously cylindrical.
  • an air guide space 24 is formed (see FIG. 1 and in particular Fig. 4) through an air duct 25 (Fig. 2) with a combustion air blower arranged above the housing 12 26 is connected.
  • This combustion air blower 26 is, as can be seen from Fig. 2, on the suction side of a combined Combustion air and exhaust silencers 27 with air preheating connected, in which the exhaust hood 2 on and empties and one separate from the exhaust gas duct Air intake opening 28 to the fan connection extends the air intake duct contains what is not particularly shown because easily imaginable.
  • This silencer and air preheater sits just above the housing 12, and the blower 26 is also advantageous using the corner gusset arranged laterally on the air preheater 27, as shown in FIG. 2 is shown.
  • the cover 9 consists of the annular part 15 and the centrally circular part 16. All burner components are mounted on part 15 as described and can therefore be completely removed with part 15 and be subjected to maintenance, for example.
  • the ring-shaped, with the heat exchanger WT firmly connected part 16 sits on studs 29 of the burner-side end wall 31 of the water-carrying Housing 12.
  • the coiled tubing with a suitable cleaning device can be cleaned. After cleaning, the nuts 32 tightened again and part 15 with its burner components is put back on and fixed by means of screw connections 33.
