Definitions

  • the subject of the invention is a gas burner more particularly intended for liquid fuels and whose originality lies in that it comprises groups of openings for the passage of the fuel gas-primary oxidant air mixture, which are closely related to each other. and which are established at very reduced dimensions so as to ensure the unification of the flame front and thus to avoid any vibration thereof, with the simultaneous effects of eliminating a very painful factor of acoustic disturbance and giving rise to flames of greater uniformity ultimately having a better specific combustion efficiency.
  • pilot flames are provided through an empty space formed between an outer sheet perforated at the level of the flame passage and the sheet which forms the body of the burner, the latter comprising groups of relatively close and established openings to small dimensions for the passage of the combustible mixture.
  • the above-mentioned empty space is supplied with a fuel-air primary oxidant mixture, originating at low flow speed from holes with reduced cross-section, so as to obtain high flame stability.
  • the main object of the present invention is to provide a burner capable of being dimensioned even for large flame powers without producing any vibration, particularly within the range of the range sensitive to the human ear.
  • the pilot flames supplied through the lateral empty spaces contribute very significantly to the stabilization of the main flames, even at very high flame powers.
  • the burner comprises a cylindrical body 1 which is supplied with combustible gas by a nozzle 2 forming a Venturi and associated with a nozzle 3, and with primary combustion air through passages 4.
  • the lateral surface of the cylindrical body 1 is pierced with openings for the flow of the mixture, these openings being grouped into several groups of slots 5 (FIG. 2) having a minimum width and a reduced length, which slots are arranged parallel to each other. coast by forming subgroups.
  • each slot 5 can be made to have a width of 0.5 mm and a length of 6 mm with a center distance of 1.2 mm, the sub -groups being spaced 2 mm apart; at each end of the lines formed by these sub-groups is provided a series of pilot openings 6, respectively 7, which are intended to stabilize the flames._The groups of openings are spaced from each other by a distance of about 15 mm. 1.
  • the arrangement indicated above makes it possible to produce a range of flames 8 (fig. 3) having a dark blue color, the flame front 9 of which, in luminous blue tint, is unique for all the openings or group slits, with the advantages indicated above in addition to a very high primary aeration rate.
  • the burner also comprises a cylindrical body, here referenced 11 (fig. 4), which has on its upper wall groups of slots 12 very close together, in the same arrangement as that previously described with reference to fig. 1 to 3.
  • the sheet 13 On the upper part of the body 11 is welded a sheet 13 cut out of openings 14 through which pass the flames which come from the individual groups of slots 12 intended for the emission of the combustible mixture.
  • the sheet 13 can in fact be constituted by the sheet itself which forms the body 11, the latter being simply extended in its circumferential development by means of folds 15 and 16 (fig. 6) formed on the sides of the raised part. of said sheet.
  • welds 17 and 18 are provided, for example by spots, on the edges of the sheet immediately adjacent to the folds 15 and 16 mentioned above.
  • Openings 19 and 20 of relatively reduced amplitude are formed on the bottom wall of the sheet metal which constitutes the body 11 of the burner, these openings being intended to allow the supply of combustible mixture at low space flow speed. empty intermediate between the sheet or body 11 and the sheet 13. This mixture supplies the pilot flames emitted through the openings 14 to lick the sides of the main flames coming out of the slots 12.
