Definitions

  • the present invention relates to a burner for a torch with rapid gas flow.
  • the burner which is the subject of the invention comprises two symmetrical half shells fixed to each other having an inlet end which adjusts and fits on the gas flow supply duct and an end thereof outlet, intermediate between the two ends, a diffusion grid constituting the nozzle means is maintained and delimits an expansion chamber and a combustion chamber, the diffusion grid has an omega-shaped section provided with recesses constituting the means nozzle for the flow and distribution of the gas flow both on its front part of circular or triangular shape and on its side walls, these being offset from the interior walls of the burner in order to create flow paths for the passing gas flow across them, flow taking place outside the combustion chamber thanks to the extension of the conical section of said chamber intended to cause an increase in speed flow of the lateral gas flow, the combustion in the chamber of the gas flow which flows through the front part of the grid, allowing the ignition of the lateral gas flow outside said chamber while promoting the attachment of the flame.
  • the diffusion grid consists of one or two sheets depending on the gas pressures used, the said sheet or sheets have recesses constituting the nozzle means, the surface of the recesses being at least equal to or greater than the outlet section of the combustion chamber, when using gas at low or medium pressure, two sheets are used, they are superimposed and joined or not joined at the front and this in order to avoid flashbacks, the section of the recesses of the upper sheet being larger than the section of the recesses of the lower sheet.
  • the burner 1 has two symmetrical half shells 2 and 3 fixed to one another by welding or any other known means, the end 4 is the cylindrical entry intended for s' emboften and fit on the rapid flow supply duct of the gas flow not shown, the end 5 is the outlet.
  • a diffusion grid 6, constituting the nozzle means is maintained, it delimits the expansion chamber 7 and the combustion chamber 8.
  • said grid 6 has an omega-shaped section whose front part 11 is circular, the perforated sheets 9 and 10 are provided with recesses constituting the nozzle means both on the front part 11 and on the side walls 12, the total surface of the recesses of the upper sheet 9 is approximately 50% greater than the total surface of the recesses of the lower sheet 10 and this in order to avoid flashbacks, the total surface of the recesses in the lower sheet 10 being equal to or greater than the outlet surface 5 of the combustion chamber of the burner 1, the grid 6 can be constituted ée by a single perforated sheet, in particular in the case of the use of gases at high pressure, while for gases at medium pressure two superimposed and joined perforated sheets can be used.
  • the grate 6 is held in the burner 1 by means of the extensions 13 of the side walls 12 which are inserted in the grooves 14 arranged on the shells 2 and 3, the insertion of the extensions 13 in the grooves 14 determines the position of the side walls 12 of the grid 6 relative to the interior faces of the burner 1 so as to generate corridors 15 for the flow of the gas flow passing through said walls 12, the spacing is such that it only allows the flow of the gas flow but not its combustion, this taking place outside the combustion chamber 8, thanks to the extension 16 of the chamber 8 of conical shape which causes an increase in the speed of flow of the lateral gas flow, the combustion in the chamber gas flow flowing through the front part of the grid allows the ignition of the lateral gas flow flowing at high speed outside the chamber while promoting the attachment of the flame.
  • expansion chambers 7 and combustion 8 can be of different shapes: in the shape of a parallelepiped, cylindrical, ovoid, etc., the shape of the grids 6 of omega section being adapted to marry the shape of said chambers, in particular that of combustion 8. J
