Definitions

  • the invention relates to a radiant burner in which pressurized fuel is injected into a chamber and combustion air is mixed in, while the derived combustion gases heat up the inner wall of a downwardly diverging reflector and recuperatively transmit sensible heat to at least the combustion air.
  • Such a radiation burner is known from DE-OS 21 07 514.
  • the truncated cone-shaped reflector terminates with an apex plane formed by a burner plate.
  • a cone In the reflector chamber there is a cone, which starts in the middle of the base plane and opens upwards, which redirects the combustion gases within the reflector chamber and guides them through the multi-layer reflector wall, the combustion gases emitting sensible heat in counterflow to the combustion air, which is conveyed by a fan
  • the combustion gases first give off their heat to the walls of the reflector, which radiate the energy absorbed according to their temperature. After that, the remaining energy of the combustion gases, as described, is still used.
  • the known embodiment requires a complicated reflector and, due to the multilayer structure, also a complex design of the reflector walls.
  • direct heat radiation from the burner plate is not possible because the cone inserted into the reflector shields this radiation. There is therefore radiation reflection and ultimately a reduction in the radiation temperature, so that the radiation is considerably impaired.
  • the invention is therefore based on the object of designing a radiant burner of the type described in such a way that, on the one hand, the advantages of utilizing the waste heat of the combustion gases are retained, and on the other hand, the radiation output is significantly improved.
  • This problem is solved by the invention as characterized in dpn Pat p nt claims.
  • the radiation from the burner is in no way impaired.
  • this is made from fuel, usually from fuel gas, and the combustible mixture consisting of air is heated particularly effectively within the mixing chamber.
  • the walls of the combustion chamber are directly exposed to the hot combustion gas, so that the heat transfer is particularly effective.
  • the mixing chamber is exposed to heat radiation which emanates from the walls of the reflector.
  • a connecting tube for the fuel gas designed for the self-suction of the combustion air
  • this connecting pipe is designed as a Venturi pipe, in which gaseous fuel acts on the central nozzle, so that the required amount of combustion air is drawn in.
  • the mixing chamber designed in one piece with the burner is completely accommodated within the reflector space. This purpose is served in particular by webs with which the mixing chamber is fastened to the apex of the reflector.
  • the attachment can also be carried out by means of one or more connecting tubes which lead to a connecting tube attached to the outer wall of the reflector. This not only saves the webs, but also further preheats the mixture flowing through the connecting pipes.
  • the vertex of the reflector opening downwards is expediently an essentially horizontal surface for the reasons of fastening the mixing chamber.
  • the latter can also be expediently clad with a ceramic plate with good thermal insulation properties.
  • a ceramic plate has the advantage of emitting heat with a very high emission coefficient when the surface is heated. Accordingly, the burner plate as the primary Radiant surface acts, the ceramically clad apex of the reflector can act as a secondary heating surface. The latter effect can be increased if the surface forming the apex of the reflector or the ceramic plate mentioned is made larger than the plate of the burner delimiting the mixing chamber at the bottom. This means that a larger proportion of heat radiation is transferred to the mixing chamber.
  • a circulating flow of the combustion gas occurs within the reflector space, which flows continuously from the burner and, after having filled the reflector space, emerge from the latter along one of the lower edges.
  • the walls of the mixing chamber which extend from the burner plate and extend in the direction of the apex are expediently made concave. In this way, they adapt geometrically to the flow being formed and further increase the heat exchange surface.
  • a further increase in heat radiation can be achieved in that the reflector walls also experience considerable heating.
  • they are advantageously made of sheet metal panels that are thermally insulated on the outside.
  • FIGS. 1 and 2 To further illustrate the invention, reference is made to exemplary embodiments shown schematically in FIGS. 1 and 2.
  • a reflector 6 can be seen, which is formed from reflector walls 12 diverging downwards.
  • the front end wall lying in the plane of the drawing is not shown.
  • the plan of the reflector 6 is therefore rectangular.
  • the plate of the burner 1 and the mixing chamber 2 are of rectangular plan. The latter is connected with webs 8 to the horizontal surface 9 of the apex of the reflector chamber 3.
  • a flow of the combustion gases can form in the reflector space 3, which flows according to the streamlines 13.
  • the walls of the mixing chamber are made concave, as indicated in the dashed representation, the convex can Increase active heat transfer as described.
  • the combustion gases finally flow out of the reflector chamber 3 along the lower edges 4, 5 of the reflector 6 after they have largely transferred their sensible heat to the mixing chamber 2, the reflector walls 12 and the ceramic plate 10 provided in the reflector apex.
  • the connecting pipe for the supply of fuel gas and combustion air can, as denoted by 7 ', penetrate one of the narrow sides of the reflector. But it can also be attached to the outside, as shown at 7. In a manner not shown, fuel gas is introduced in the direction of arrow 14, which draws in the combustion air. Instead of the webs 8, connecting pipes 7 can also extend from the connecting pipe, which lead into the mixing chamber 2 and at the same time allow the latter to be fastened in the apex of the reflector chamber 3.
  • the reflector can also have a wall which is parabolic in cross section.
  • this has the advantage that it can be easily bent from a single rectangular sheet metal blank.
  • the reflector is asymmetrical. If this is done in the form shown in FIG. 2, for example, a particularly broad radiation field is created.
  • a reflector wall 15 which carries a burner 1 with a mixing chamber 2 or also a second burner 1 'with a second mixing chamber 2', is arranged inclined. At the upper edge 16 of the burner wall 15 there is a broad reflector wall 17 in the downward direction, while at the lower edge 18 of the reflector wall 15 there is an only relatively narrow reflector wall 19.
