Definitions

  • the invention relates to a radiant burner in which a burner for pressurized fuel and a one-piece mixing chamber of rectangular plan are attached to a flat and horizontally in the installed state vertex of a reflector, which reflector diverges from the vertex downwards while a Connection pipe designed for self-suction of the combustion air penetrates one of the narrow end faces of the reflector.
  • Such a burner is known from US-A-3 805 736.
  • the entire bottom surface of the mixing chamber is connected to the top surface of the reflector.
  • the reflector is to be air-cooled by means of a fan in order to prevent an increase in temperature due to heating by means of the combustion gases.
  • the latter are discharged downwards with the exiting fan air, whereby they mix with it while cooling noticeably.
  • the invention is based on the object of designing the radiant burner in such a way that waste heat utilization of the combustion gases is made possible and that the radiant power is thereby substantially improved.
  • recuperative air preheating is created, in which the combustion gases are acted directly on the mixing chamber of the burner and on all sides thereof, since the burner and mixing chamber are completely accommodated within the reflector space.
  • the reflector is held at a distance from the apex of the reflector, so that the apex surface is used to allow a flow around the mixing chamber.
  • the size of the apex area leads to an increased heat transfer both for the radiation into the room to be heated and for the radiation to the mixing chamber to be heated for the purpose of preheating.
  • the connecting pipe for the self-priming of the combustion air is advantageously attached to the outside wall of the reflector.
  • the top of the reflector can be provided with a ceramic plate with good heat insulation properties.
  • a ceramic plate When heated on the surface, such a ceramic plate can emit heat with a very high emission coefficient. Accordingly, while the burner plate acts as the primary radiation surface, the vertex of the reflector, which is ceramic-clad in the manner mentioned, can act as a secondary heating surface.
  • 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 is 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.
  • 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 plates of the burner 1 and the mixing chamber 2 are also of a rectangular plan.
  • a flow of the combustion gases can form in the reflector space 3, which flows according to the streamlines 13. If the walls of the mixing chamber are made concave, as indicated in the broken line, the convective heat transfer can be increased 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 provided in the reflector apex.
  • the connecting pipe for the supply of fuel gas and combustion air passes through, as denoted by 7 ', one of the narrow sides of the reflector. It can be attached to the outside in a continuation, as shown with 7. In a manner not shown, fuel gas is introduced in the direction of arrow 14, which draws in the combustion air.
  • 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.
