Definitions

  • the invention relates to a gas burner, in particular for liquefied petroleum gas, for upright installation in a heat exchanger or a space heater according to the preamble of patent claim 1.
  • Gases with a low ignition speed require an additional air supply to mix with the gas emerging from a nozzle.
  • this requirement is met in that a tubular burner housing forms an air chamber, a mixing tube and a burner mouthpiece. Because of their different tasks and design, these sections are usually made as individual parts from different materials. In addition to the large amount of material, effort and complicated and extensive assembly, these burners have the further disadvantage of a large overall height, which in turn has an unfavorable effect on the size of the combustion chamber of the heater.
  • the invention is based on the object of creating a gas burner, in particular for liquefied petroleum gas, which is distinguished by a low overall height and is particularly suitable for standing installation in a heat exchanger.
  • the simple gas burner shown in FIG. 1 consists of a burner mouthpiece 1 with a burner cone 2 that widens outwards and is spanned by a metal sieve 3.
  • the mouthpiece which consists of a rotating body, has an attachment sleeve 4 at the other end.
  • An annular groove 5 also serves to receive an end plate or fastening plate 6.
  • a mixing tube 8 is inserted tightly into the attachment sleeve 4 and is provided with annular ribs 9 at least on its inner surface.
  • a gas nozzle 12 with a gas guide tube 13 is arranged at its inlet opening 10.
  • An ignition electrode 15 and optionally a thermocouple (not shown) is located above the metal screen 3.
  • the main advantage of the mixing tube according to the invention with a corrugated or corrugated inner surface is obtained if a flexible metal hose 20 is used, which according to FIG. 2 can be folded over to further reduce the overall height.
  • a metal hose has like the mixing tube 8, has a corrugated or ribbed inner surface 22, which usually continues helically. This ribbing also causes the mixture flow to form a flow screw, which results in a further intensification of the mixing action.
  • the mixing tube 20 is traversed at its air inlet opening 21 by a gas guide tube 24 with a nozzle opening 25, so that the so-called primary air can flow into the mixing tube on both sides thereof.
  • a burner cap 30 This consists of a flat annular surface 31 which engages in the groove 5 in the burner mouthpiece and thus holds the burner. 3, a plurality of holes 32 are provided in this ring surface, which are directed towards the burner flame and in this way act like nozzles for the secondary air flowing up the outside of the mixing tube and sucked into the combustion chamber 36.
  • the burner cap also forms a fitting cylinder 34 for attaching a flame tube 35 or other heat exchanger forming the combustion chamber. By means of a base 38 with a mounting flange 39 adjoining this fitting cylinder 34, this burner cap is fastened to an intermediate floor 40 which seals off the circulating air or hot air area from the fresh air or combustion area.
  • a pre-chamber 42 accommodating the mixing tube can be formed.
  • the mixing tube E t is fastened to the intermediate floor, for example by means of a holding clamp 41.
  • a blower (not shown) for conveying fresh air is advisable.
  • the fresh air enters the pre-chamber 42, partly flows into the mixing tube 20, where it mixes with the gas emerging from the nozzle 25 before the gas-air mixture on the metal screen is ignited, and on the other hand past the mixing tube and mouthpiece through the nozzle holes 32 as secondary air to the flame.
  • the burner mouthpiece can have any other usual shape and design.
  • the mixing tube can also narrow towards the burner mouthpiece, just as its corrugated inner surface can be limited to one or more sections. Smooth inner wall sections can be of advantage if a longer mixing tube is required for constructional reasons or is desired for other reasons and a corrugated inner surface that is too long would impair the flow conditions if a fan for supplying the fresh air is not available.
  • the mixing tube according to FIG. 2 could consist of a flexible, corrugated or corrugated and a smooth tube part.
  • the burner parts can also have cross sections other than circular.
  • simple slits or roof hatch-shaped openings can also be formed in the annular surface 3i. It is particularly advantageous if this second air openings are directed with their longitudinal planes angle, for example 45 0, relative to the radial direction inwards.
