Definitions

  • the present invention relates to a combustor assembly for a Heater, in particular vehicle heater, comprising a housing with a housing wall and a fuel supply through the housing wall therethrough.
  • Installation position generally depends on the specific vehicle type. Regardless of the installation position, however, the heating output, the noise emission and the exhaust gas emission must be constant.
  • evaporator burners where the fuel is through a porous evaporator medium is released into a combustion chamber, the problem is that by changing the installation position, the introduction of the fuel into it porous evaporator medium can be affected because of the fuel generally become porous before initiation and after initiation into it Medium is distributed due to gravity.
  • a very uneven one Distribution leads to a correspondingly uneven evaporation of Fuel into the combustion chamber, which can result in that in the Combustion chamber combustion leading to increased exhaust gas emissions leads to impaired the starting behavior of such a combustion chamber and that an excessive deposition of combustion residues in the combustion chamber occurs, which in extreme cases leads to failure of the combustion chamber can lead.
  • a Combustion chamber assembly for a heater especially a vehicle heater, comprising a housing with a housing wall and a fuel supply through the housing wall, the housing wall on the fuel distribution element covering the side facing a combustion chamber, the one together with the housing wall
  • Fuel distribution channel arrangement limited, being in the fuel distribution element a plurality of fuel inlet openings are formed is for routing fuel from the fuel distribution channel assembly towards the combustion chamber.
  • the fuel is not directly in from the fuel supply Given direction to the combustion chamber, but there is a pre-distribution instead, which is an equalization of the fuel discharge into the Combustion chamber and thus a significantly improved independence from the Installation position.
  • a pre-distribution instead, which is an equalization of the fuel discharge into the Combustion chamber and thus a significantly improved independence from the Installation position.
  • Form the fuel distribution channel arrangement in the housing wall or / and the fuel distribution element a groove-like depression is trained.
  • the at least one fuel supply opening into the fuel distribution channel arrangement in the area between two Fuel inlet openings opens.
  • the arrangement according to the invention is particularly advantageous when facing the combustion chamber Side of the fuel distribution member, a fuel from the fuel introduction ports receiving evaporator medium is provided.
  • This Evaporator medium so generally porous evaporator medium, can for example fleece material, fabric material, web material, braid material, Include foam ceramic material or any material that due to its structural composition or porosity for the promotion or distribution of fuel introduced into it Can cause capillary action.
  • the Housing is pot-shaped with a bottom wall and a ring-like Peripheral wall, the fuel distribution element ring-like is formed and the peripheral wall of the housing at least partially covered.
  • the fuel distribution element at least one Forms or contains part of a heating arrangement.
  • a combustion chamber assembly according to the invention with the Reference numeral 10 denotes.
  • the combustion chamber assembly 10 includes a Housing 12, which is generally a wall 14 with a pot-like structure forms.
  • This wall 14 comprises a wall base 16 and this then an essentially cylindrical or also ring-like Circumferential wall 18.
  • On an inner side surrounding a combustion chamber 20 22 of the peripheral wall is also cylindrical or ring-like Fuel distribution element 24 arranged on the inside 22 of the peripheral wall 18 lies flush and in the example shown is then positioned on the bottom wall 16.
  • In the peripheral wall 18 is on the inside 22 one, for example, by milling formed annular recess 26 is provided which has a fuel distribution channel forms.
  • Fuel can be introduced into this annular recess 26. In relation to a longitudinal axis L radially inwards, this depression is 26 completed by the fuel distribution element 24. In the fuel distribution element However, 24 are in several circumferential positions Fuel inlet openings 30 are provided. The in the recess 26 and in Fuel injected into the fuel distribution channel can after with a relatively low flow resistance in this recess 26 in Has distributed circumferential direction about the longitudinal axis L, through these fuel inlet openings 30 continue to flow towards the combustion chamber 20. there occurs the fuel flowing through the fuel inlet openings 30 into one on the inside 32 of the fuel distribution element 24 provided porous evaporator medium 34.
  • the combustion air is in two areas in the example shown the combustion chamber 20 initiated. Firstly, in the central area Bottom wall 16 a combustion air inlet opening 38 is provided, on the other hand it is not through the fuel distribution element 24 covered area 40 of the circumferential wall 18 in the circumferential direction distributed a plurality of combustion air inlet openings 42 are provided, so that the combustion air is also introduced very evenly into the combustion chamber 20. It should be noted that of course, the combustion air only in the area of the bottom wall 16 or only in the region of the peripheral wall 18 in the combustion chamber 20 can be initiated.
  • a glow plug trained igniter 44 is provided, which for starting the high temperatures required for combustion. This can of course also be provided at a different position be, for example, on the peripheral wall 18 and through the Projecting fuel distribution element 24 or the evaporator medium 34.
  • the combustion chamber assembly 10 has not yet been preheated by the incineration process, to accelerate the evaporation of the fuel, it is possible to have a heating arrangement ready in the fuel distribution element 24, for example in the form of a heating coil or the like, or the fuel distribution element 24 as part of such a heater, so that by energizing this electrically operated heater the porous evaporator medium 34 and thus also the one contained therein liquid fuel and therefore the rate of evaporation can be increased.
  • the recess 26 instead of or in addition to providing the same in of the peripheral wall 18 also on the outer peripheral side of the fuel distribution element 24 may be provided.
  • the Well 26 may have multiple well portions to be defined the fuel in different circumferential areas or axial areas to lead. It is also possible to have several such ring-shaped depressions to keep ready axially one after the other and for example by a single or through separate fuel supply openings supply.
  • the combustion chamber assembly 10 shown in the figures or one of these having heater is installed, for example, that basically the fuel supply opening is on the top. Even if from Such an installation position, for example, one way or the other Page is deviated in an angular range of 90 °, will continue by having the recess 26 or the fuel inlet openings ready 30 ensures a very even distribution of the fuel. This means that when defining such a device in one There is greater freedom for the vehicle without causing the mixture to form and thus the combustion is significantly affected. All this is with a very simple and therefore also inexpensive construction reachable.
