Definitions

  • the invention relates to a gas blower burner according to the preamble of patent claim 1.
  • Such a gas blower burner is in Handbook for Heating Technology (34th Edition, 2002, publisher: Buderus Heating Technology, ISBN 3-410-15283-0, page 242 ) under the name Logatop®.
  • This consists of a flame body with a circular cylindrical surface, wherein the flame body is closed at one of its two end faces and at the other, arranged on a burner support end face a supply for a gas-air mixture to be burned.
  • the lateral surface is provided with a plurality of outlet openings for the gas-air mixture and enclosed by a formed of metallic wires, tightly or closely resting focal surface.
  • the function of such a burner is well known and should therefore be briefly explained at this point: via the feed arranged on one end side, the gas-air mixture to be combusted is conveyed into the interior of the flame body. From there it passes through the outlet openings to the burning surface and is burned there.
  • the lateral surface is formed as a perforated plate, on which rests the actual, formed of wires burning surface.
  • This focal surface is formed in the aforementioned burner as a wire mesh.
  • the distances of the wires from each other are uneven, d. H. the mesh size varies from wire to wire. Overall, one can also speak of a confused arrangement of the relatively thin wires.
  • Wire knits for the stated purpose are relatively expensive. In addition, they have the disadvantage that they easily lose mechanical strength due to the relatively thin wires and the uneven distribution thereof, thus possibly resulting durability problems.
  • the invention has for its object to improve a gas blower burner of the type mentioned above with respect to the disadvantages of the prior art.
  • the focal surface is formed from a wire mesh.
  • the gas blower burner consists of a flame body 1 with a circular cylindrical outer surface 2 in a manner known per se.
  • the lateral surface 2 is provided with a large number provided by outlet openings 5 for the gas-air mixture.
  • the entire lateral surface 2 is provided with such openings arranged at regular intervals, so that a flame can burn on the entire outer surface of the flame body 1.
  • the jacket surface 2 is surrounded by a thin surface (distance equal to zero) of the focal surface 7 formed by metallic wires 6.
  • the flame body 1 itself is in a conventional manner at one of its two end faces 3 (gas-tight if necessary) closed and has at the other, arranged on a burner support 13 end 4 a supply for a gas-air mixture to be burned.
  • the focal surface 7 is formed of a wire mesh.
  • the burning surface is thus not designed as a so-called knitted fabric in particular. Rather, the use of a fabric provides significantly improved flame stabilization and also improved durability.
  • a type of fabric for the wire mesh is in particular the so-called linen weave (also called cloth weave: warp and weft each other at right angles) provided, which represents the simplest way of weaving a fabric and has the closest intertwining of warp and weft.
  • the wire mesh consists of warp and weft threads, which are each arranged obliquely (preferably 45 °) extending to the cylinder axis of the flame body.
  • a particularly preferred development of the gas blower burner according to the invention is provided with regard to the blank of the wire mesh.
  • a parallelogram typically properties of the parallelogram: opposite sides are parallel, opposite sides are the same length, opposite angles are the same size, two adjacent angles result in 180 °, bisecting the diagonal cut each other
  • a part of the wires 6 is parallel to two opposite sides or edges of the Parallelogrammzuites.
  • the wire cloths are made as parallelogram blanks from a continuous wire web having a defined width B, wherein two opposite sides of the wire cloth each have an outer edge of the wire cloth web and the two other opposite sides in each case form a cutting edge for each next parallelogram blank.
  • a cover-shaped element 9 is arranged.
  • This has a cylindrical peripheral edge 10, which encloses the wire mesh-carrying lateral surface 2.
  • pressure joining is called in the jargon also “clinching” or “ Clinching ": this is a procedure for joining sheets without Use of a filler material; one can count on both the joining process and the forming process, since the compound is achieved by forming the material).
  • the lid-shaped element 9 has centrally a bulge 11 pointing into the interior of the flame body 1. This can, as shown, be formed dome-like with a slight curvature.
  • the mixture feed already mentioned above is formed on the end face 4 of the flame body 1 as a cylindrical support tube 12 fastened to the burner carrier 13.
  • This encloses - as the peripheral edge 10 on the lid-shaped element 9 - the outer surface carrying the wire mesh 2, which is also provided here, that the support tube 12, the wire mesh and the lateral surface 2 (again in this arrangement order) are connected to each other by pressure.
