Definitions

  • the present invention relates to an ignition device, particularly for an atomizer burner of a motor vehicle heating appliance.
  • spark gaps In heating appliances, such as are used as so-called supplementary heaters or auxiliary heaters in motor vehicles, fuel is fed together with combustion air into a combustion chamber and is combusted there. The combustion is ignited by so-called spark gaps, such as also find application in heating burners in heating installations of buildings.
  • the spark gaps provided for ignition as used in particular in connection with so-called atomizer burners, in which the fuel to be burned is injected together with the combustion air at high speed and thus atomized, are comparatively expensive and thus represent a not inconsiderable cost factor, particularly for smaller kinds of heating devices.
  • the present invention has as its object to provide a cost-efficient ignition device which in particular can also be used in connection with atomizer burners.
  • an ignition device particularly for an atomizer burner of a motor vehicle heating appliance, including a glow ignition member and screening material which can take up fuel and which at least partially surrounds the glow ignition member.
  • the present invention takes the path of using an ignition device, working on the principle of a glow ignition device, which is markedly more cost-effective to obtain and to build in. This was heretofore not possible, since the removal of heat from a glow ignition member was very great due to the flow speed of the materials injected into the combustion chamber in the case of atomizer burners, so that the glow ignition member could no longer produce, even in its immediate neighborhood, the temperature required for the ignition of the combustion materials. Since however according to the invention the glow ignition member is screened by screening material, the heat transfer to the material flowing at high speed is markedly reduced.
  • the fuel injected at high speed together with combustion air and thus atomized is taken up in the screening material, so that fuel collects in the immediate surroundings of the glow ignition member, which is screened from a high speed flow, and can now be ignited by the glow ignition member.
  • the expression “material which can take up fuel” includes material which because of its design forms cavities in which the fuel can collect; a direct impingement of the fuel into the material itself does not necessarily have to take place. Nevertheless, materials are also included which have a bodily structure such that the fuel is taken up into them and thus, for example, absorbed, as is the case for a porous material.
  • the glow ignition member is substantially completely screened against direct flow onto it of material delivered by an atomizer nozzle.
  • the glow ignition member is carried by a support arrangement and that screening material is arranged spaced from the support arrangement at least in a region.
  • porous materials can be used, foamed ceramic material being a useful material here because of its thermal and mechanical resistance.
  • mesh-like material such as e.g., wire mesh, is also possible. It should be mentioned that the expression “mesh” is to express the fact that material sections are present which interengage or overlap one another in the manner of a mesh, warp knit fabric, weft knit fabric, or woven fabric. A limitation to a given manner of production of this mesh-like material is not thereby introduced.
  • FIG. 1 shows a sectional view of a first embodiment of an ignition device according to the invention
  • FIG. 2 shows a view corresponding to FIG. 1, of an alternative embodiment.
  • a glow ignition member is generally denoted in FIG. 1 by the numeral 10 .
  • the glow ignition member 10 comprises a glow plug or a glow pin 12 of conventional construction, which can thus have, for example, a heating coil and if necessary a control coil as well as insulating powder or the like, in a heat-resistant glow tube.
  • the glow pin 12 is supported in a support member 16 provided with an external thread 14 , and projects over this support portion 16 with its free end region 18 , which for example then contains the heating coil.
  • the support member 16 is supported in a substantially cylindrical support sleeve 20 with an internal thread 21 .
  • the support sleeve 20 can be installed on a housing 22 , shown schematically, of a heating burner 24 .
  • This heating burner 24 furthermore has an atomizer nozzle 26 , shown schematically.
  • Combustion air is introduced at high speed into the combustion chamber 28 of the heating burner 24 by means of the atomizer nozzle 26 .
  • the combustion air flowing in, entrains the fuel and atomizes it, so that a mixture of combustion air and very fine fuel particles, denoted by 30 in FIG. 1, is produced and flows at high speed into the combustion chamber 28 .
  • the free end region 18 projects beyond the housing wall 22 into the combustion chamber 28 .
  • a substantially cylindrical screening member 32 is provided in order to protect this free end region of the glow pin 12 from the air/particle stream flowing in at comparatively high speed. This extends, with the formation of an interspace 34 , at a spacing along the free end region 18 of the glow pin 12 , and thus along that region of the glow pin 12 which projects beyond the support member 16 .
  • the screening member 32 in its section extending along the support sleeve 20 , then abuts on, and is supported on, the inner surface of the support sleeve 20 .
  • the screening member 32 extends, together with the free end region 18 of the glow pin 12 , into the combustion chamber 28 , and in fact in the embodiment example shown, as far as the free end region 18 of the glow pin 12 extends also. In this manner, at least a portion of the air/particle stream 30 delivered from the atomizer nozzle 26 is prevented from directly striking the surface of the glow pin 12 .
  • the screening member 32 is such, or is formed of such material, that fuel which is contained in the air/particle stream 30 striking this screening member 32 can be taken up in this screening member 32 .
  • the use is possible of a member formed of wire mesh, or of a porous material such as, for example, foamed ceramic.
  • the fuel taken up in the screening member 32 or absorbed into it is transported to the inside, i.e. the side toward the glow pin 12 , of the screening body 32 , on the one hand by the fuel newly flowing on from the outside, and possibly on the other hand by capillary action. An atmosphere enriched with fuel is thus formed in this region and also in the space region 34 .
  • the glow pin 12 or its free end region 18 is now extensively screened against the air/particle stream 30 , the removal of heat from the glow pin 12 due to flow is reduced to such an extent that the glow pin 12 can produce a temperature in its surroundings which is sufficient for the ignition of the fuel present there. After the resulting ignition, the combustion immediately propagates over the whole combustion chamber 28 .
  • the present invention thus provides the possibility, even in so-called atomizer burners, of employing glow pins, which are very cost-effective in comparison with spark gaps, for the ignition of the injected air/fuel mixture, since the region of the glow pin relevant for igniting this mixture is extensively screened against the mixture flowing on at high speed and thus against an excessive removal of heat induced by flow.
  • the glow pin 12 is arranged such that it does not project into the combustion chamber 28 , or does not project so far into the combustion chamber 28 as in the embodiment according to FIG. 1.
  • the screening material surrounding the free end region 18 of the glow pin 12 i.e., the screening member 32 of substantially cylindrical constitution, however extends out over the free end region 18 of the glow pin 12 here, and if necessary even into the combustion chamber 28 .
  • a still better screening of the free end region 18 of the glow pin 12 is thus attained.
  • an extension of the screening member 32 like a hood in its region projecting beyond the free end region 18 of the glow pin 12 could also be considered, thus completely excluding the direct flow of the air/particle stream 30 onto the glow pin 12 .
  • an interspace 36 is created between the support sleeve 20 and the screening member 32 in the end region of the support sleeve 20 near to the housing wall 22 .
  • This interspace leads to an improved thermal insulation of the screening member 32 with respect to the support sleeve 20 and thus reduces the removal of heat from the region relevant for ignition.
  • the material which can take up fuel particles i.e., the screening member 32
  • the screening member 32 can contact the glow pin 12 or its free end region 18 at least over a region, so that the screening member 32 can already be brought to a markedly higher temperature. It is also of course possible to adapt both the glow pin 12 and also the screening member 32 as regards their design, dimensions, and positioning with respect to the atomizer nozzle.
  • the ignition device according to the invention working on the principle of a glow ignition, can be operated with comparatively lower electrical power.
