Definitions

  • the invention relates to a burner especially for heating systems with a Combustion chamber in which a gas-air mixture is combustible in a burner body is, wherein the burner body made of a hollow wire material consists.
  • the invention further relates to a method for producing a such a burner body.
  • DE 195 27 583 describes a burner which has a combustion chamber.
  • the combustion chamber is with a pack of heat-resistant Wire material filled out.
  • the gas / air mixture can be placed in this pack initiated and ignited here.
  • the combustion chamber is surrounded by a heat exchanger.
  • a temperature gradient occurs in the burner body.
  • the combustion temperature inside the burner body is very high.
  • edge regions facing heat exchangers are relatively low Temperatures.
  • In the strongly heated core area of the burner body there is a high one Given nox pollutant development, while in the highly chilled The edge area mainly produces CO.
  • This object of the invention is achieved in that in the wire material or several cooling elements are incorporated, which are in direct surface contact stand with the wire material.
  • the cooling elements are arranged inside the wire material, the decoupling of the temperature and thus the distribution of the temperature in the Control inside the burner body. It can also be used to set a temperature where there is both low NOx and CO evolution.
  • the cooling tubes over soldering is attached to the wire material.
  • the wire material consists of at least a first and a second material web, which in their Longitudinal extension transverse to the parallel tubular Cooling elements are arranged that the material webs the cooling elements border laterally, and that the material webs in the area between the Contact cooling elements with each other.
  • the wire material is made of there is at least a first material layer and a second material layer that the cooling elements are tubular and run parallel to one another, that the material web on the longitudinal sides of the cooling elements create, the first web of material substantially parallel to the is second web of material, and that the webs of material in which the cooling elements adjoining area by means of constrictions are.
  • the voids within the wire material can be covered with steel wool or the like to be filled out.
  • the porosity of the steel wool is chosen so that combustion takes place within the burner body.
  • a method of manufacturing an at least partially from a wire material existing torch body for a torch provides that in the wire material Cooling elements are installed, and then the wire material is pressed.
  • the degree of compression depends on the desired size of the cavities within the wire material. The cavities then allow combustion inside the burner body.
  • the burner body for a gas burner.
  • the burner body has a plurality of cooling elements 13 running parallel to one another on.
  • the cooling elements 13 are designed here as water-carrying pipes, surrounded by a wire material.
  • the wire material essentially has a first and a second material web 11 and 12.
  • the material webs 11, 12 extend transversely to the cooling elements in their longitudinal extent 13.
  • the material webs are alternately on the top and bottom sides of the adjacent cooling elements 13.
  • the two material webs 11, 12 intersect in the areas between the Cooling elements 13 (intersections 15). Form between the material webs 11, 12 Cavities 14.
  • the cavities 14 are made with a filling material 16 lined.
  • the filling material 16 can be steel wool, a steel mesh or a Steel mesh.
  • The, acc. Fig. 2 prefabricated burner body can then be pressed. This becomes the material webs 11 and 12 existing wire material and the filling material 16 pressed such that a Defined cavity geometry is created within the burner body.
  • the Pore size of the cavities is chosen so that combustion of the supplied Gas-air mixture takes place inside the burner body.
  • FIG. 3 shows a further embodiment variant of a burner body shown.
  • the wire material from a first and a second layer of material 17 and 18.
  • the first Material layer 17 is placed on the mutually parallel cooling elements 13.
  • the second layer of material rests on the underside of the cooling elements 13.
  • Constrictions 19 used to one firm connection of the cooling elements 13 to the wire material.
  • the constriction 19 can be a wire that the connects upper material web 17 to lower material web 18.
  • a filling material 16 arranged in the area between the two material webs 17 and 18.
  • To manufacture the burner body first go to the lower one Material web 18 applied the filler 16. Then the filling material 16 are covered with the upper layer of material 17.
  • the cooling elements 13 For introduction the cooling elements 13, a channel is pushed into the wire material with a mandrel. The cooling element 13 can be inserted through this channel. Subsequently the cooling element 13 can be fixed with the constrictions 19. Before the cooling elements 13 are introduced, they can optionally be soldered be wrapped. The burner body thus prefabricated can in turn press so that a predeterminable pore size inside the burner plate arises. If the cooling elements 13 were wrapped with a solder foil, so in the subsequent soldering process a material connection made between the wire material and the cooling elements 13.
