Definitions

  • the invention relates to a burner of a vehicle heating device, which has:
  • a blower for supplying combustion air b) a combustion chamber which has a porous lining on part of its inner surface; c) means for supplying fuel to the liner; d) and an electric glow plug to ignite the fuel evaporated from the lining or to ignite the
  • the glow plug has been arranged either in a nozzle protruding radially outward from the combustion chamber peripheral wall. Or you have positioned the glow plug behind the combustion chamber floor.
  • the invention has for its object to design the burner with respect to the arrangement of the glow plug so that favorable ignition conditions result and the glow plug is accommodated in a particularly space-saving manner.
  • the burner is characterized according to the invention in that e) the glow plug is arranged such that its longitudinal axis lies essentially in a tangential plane of the peripheral wall of the combustion chamber.
  • This arrangement of the glow plug brings a large part of its glow area into favorable proximity to the interior of the combustion chamber. At the same time, particularly little space is required around the combustion chamber.
  • the position and arrangement of the glow plug can also be expressed in such a way that its longitudinal axis runs essentially in the tangential direction relative to the combustion chamber circumferential wall, this should not mean that the longitudinal axis of the glow plug necessarily lies in a plane that is perpendicular to the longitudinal axis of the combustion chamber runs. Rather, the longitudinal axis of the glow plug can assume any position in a tangential plane of the peripheral wall of the combustion chamber, and can run parallel to the longitudinal axis of the combustion chamber in the even favorable limit case.
  • the plane in which the longitudinal axis of the glow plug lies can be compared to the plane which, in the mathematical sense, is the tangential plane of the
  • Combustion chamber peripheral wall is to be slightly shifted towards the interior of the combustion chamber or away from the interior of the combustion chamber, as is also shown by the exemplary embodiments described below.
  • the glow area of the glow plug is preferably arranged in an outer secondary chamber of the combustion chamber and the secondary chamber is connected to the combustion chamber via an opening. In this way, the glow plug is protected against impairments due to the conditions prevailing in the combustion chamber, in particular with regard to exposure to flame and contamination.
  • Said opening preferably leads through the lining of the combustion chamber, it being particularly expedient if the lining has a surface area facing the auxiliary chamber next to the opening or around the opening.
  • the glow area of the glow plug is arranged in a recess space of the lining which is connected to the combustion chamber via an opening. This also results on the one hand, favorable ignition conditions and, on the other hand, a partitioning of the glow plug against the effects of the conditions in the combustion chamber.
  • the lining has a circumferential area and a bottom area as an integral built-in part.
  • the training as a holistically manufactured built-in part allows a particularly efficient production and leads to an optimal distribution of the supplied fuel in the lining.
  • Particularly well suited materials for the lining or the built-in part are metal web, metal mesh, metal sintered body and porous ceramic materials.
  • metal web, metal mesh or the like one can in particular start from a disk-shaped blank, which is then e.g. cup-shaped is pulled or pressed.
  • the lining can also be made from a blank. Any openings required may e.g. can be easily manufactured by punching.
  • At least one is preferably in a wall which is adjacent to the rear side of the lining facing away from the combustion chamber
  • Inflow opening provided for combustion air.
  • the combustion air flowing through these inflow opening (s) then passes through the lining and promotes the removal of fuel vapors from the lining into the combustion chamber; the combustion air flowing in there desirably enters the combustion chamber in finely divided form. As a rule, it is only part of the total combustion air that flows into the combustion chamber in this way.
  • the means for supplying fuel have a fuel supply channel opening out to the liner and that the opening is at a fairly short distance from the point where the glow plug glow region is close to the liner.
  • the lining is particularly highly saturated with fuel.
  • the mouth can conveniently lie essentially in the same cross-sectional plane of the combustion chamber as the glow plug, the angular distance between the mouth and the point at which the glow area of the glow plug is close to the lining being less than 90 °, preferably less than 60 ° .
  • an air supply prechamber of the combustion chamber can be provided.
  • One or more combustion air supply pipes are preferably provided, which open into the air supply prechamber. It is particularly favorable if this feed tube or these feed tubes run essentially tangentially to a peripheral wall of the air feed prechamber.
  • an essentially axially running combustion air supply pipe can be provided, which opens into the air supply prechamber, wherein - preferably at the transition between the prechamber and the combustion chamber - a baffle is provided for generating a swirl component of the air supply.
  • the described ways of supplying the combustion air using an air supply pre-chamber aim to allow combustion air to flow into the combustion chamber with swirl, which is favorable for complete combustion and for safe burner operation over a larger output range. If several, tangentially running combustion air supply pipes are provided, these preferably open out into the prechamber distributed around the circumference.
  • a glow plug sometimes also called a rod candle, is preferably provided as the glow plug.
  • glow plugs have a coated filament.
  • the essentially cylindrical glow plug, rounded at its free end, is made of ceramic or metallic material. The glow plug reaches high temperatures very quickly and is less sensitive. In addition, the power consumption per ignition process is lower.
  • Vehicle heaters for which the burner according to the invention is intended are intended in particular for installation in passenger cars, trucks, ships, mobile homes, caravan trailers, bulldozers and the like.
  • the heater can be integrated into the liquid circuit which is usually provided for cooling the internal combustion engine and heating the interior of the vehicle.
  • the vehicle heater can either be a so-called water heater, which emits the generated heat to a liquid circuit, or a so-called air heater, which emits the generated heat directly as a warm air flow.
  • Petrol or diesel are primarily considered as fuels.
  • the burner according to the invention can also be used as a heat generator for the thermal regeneration of particle filters, in particular in

  • annular partition wall 22 running transversely to the longitudinal axis 24 of the burner.
  • a porous lining 24 is then arranged on the combustion chamber side, which is overall pot-shaped or cup-shaped and has a base region 26 and has a peripheral region 28.
  • the bottom area 26 has such a large central opening that it just fits around the insert 16.
  • the left end face of the base region 26 in FIG. 1 abuts the partition 22.
  • the outer circumferential surface of the circumferential region 28 lies against the inner circumference of the combustion chamber 2. In the axial direction, the lining 24 is shorter than the insert 16.
  • the porous lining 24 is preferably made of metal web, metal mesh, porous sintered metal or porous, ceramic material. In the illustrated embodiment, the liner 24 is an integral part.
  • a tangential or peripheral glow plug socket 30 is attached to the side of the outer circumference of the peripheral wall 20 of the combustion chamber 2 and runs vertically in the embodiment shown.

  • the glow plug 4 designed here as a glow plug, is screwed into the socket 30.
  • the glow area of the glow plug 4 is designated 32 (FIG. 2).
  • the longitudinal axis of the glow plug extends in the tangential direction relative to the combustion chamber peripheral wall 20, as can be clearly seen in FIG. 2.
  • the peripheral wall 20 is broken.
  • the lining 24 also has an opening, which, however, is somewhat smaller than the opening in the peripheral wall 20.
  • An opening 34 is thus formed as a transition between the interior of the connector 30 and the interior of the combustion chamber 2.
  • a first part of the combustion air required by the fan 8 enters the prechamber 14 via two pipes 36.
  • the two tubes 36 run tangentially to

  • the combustion air flows from the pre-chamber 14 into the insert 16 and flows from there, partly through radial openings 38 into the space between the insert 16 and the peripheral wall 20 of the combustion chamber 2, and partly out of the right end of the insert 16.
  • Insert 16 are provided in the peripheral wall 20 of the combustion chamber 2.
