Definitions

  • the present invention relates to a gas burner of the type comprising a shell, fitted internally with a heat-insulating lining, provided with internal projections and at the center of the concavity from which opens an injector connected to a gas supply pipe.
  • the invention aims in particular to obtain an improvement in the heat capacity, therefore a saving in gas consumption for a given job, compared with known burners.
  • the invention provides that the internal projections of the heat-insulating lining consist of ribs distributed, in principle, regularly over the internal surface of the lining, starting from the front edge and going towards the center of this internal surface and having a helical profile capable of imparting a gyrating movement to the flame.
  • Such an arrangement increases the contact surface of the flame with the hot lining and, consequently, increases the combustion rate, which very significantly improves the efficiency of the burner from which hot gases and no longer a flame emerge.
  • the ribs will preferably have a thickness which decreases from the edge towards the center of the burner.
  • the shell may be simply hemispherical, but will advantageously include an attached annular element, possibly removable, arranged so as to reduce the outlet orifice and ensure focusing of the flame.
  • the burner comprises a metal shell 1 of circular orifice and an axial injector 2.
  • the shell 1 is internally lined with a heat-insulating coating 3, for example made of mineral wool or concrete, with low thermal inertia.
  • This lining 3 has a number of ribs 4 projecting towards the inside of the burner, regularly distributed and of helical profile, the thickness of which decreases from the orifice of the burner towards the injector.
  • the flame leaving the injector is guided in the channels formed between the ribs 4 and lick a surface at high temperature much larger than in the absence of such ribs. This therefore results in an increase in the heat capacity of the burner with acceleration of the combustion of the gas-air mixture.
  • the hemispherical shell is extended forward by a tubular part 5, one of the bases of which has the same shape as the orifice of the shell 1 and the other base of which 6 has a smaller surface area.
  • This annular element can be removably attached to the shell 1.
  • This burner ensures “focusing” of the flame.
  • the outlet 1 of the shell 1 may, of course, not be circular. It can, for example, be of elongated rectangular outline, or square.
