Definitions

  • the present invention relates to a burner for a torch with rapid gas flow.
  • burners for gas torches comprising an expansion chamber and a combustion chamber separated by a diffusion grid constituting the nozzle means, allowing the distribution of the gas flow in the combustion chamber where the gas is consumed, this kind of burner during the combustion of the gas has its side walls which are brought to very high temperature not admitting the possibility of gripping by the user. So as to overcome this drawback, some burners are equipped with a secondary surround offset from the side walls and provided with large recesses in order to allow ventilation.
  • 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, in its extension, an outlet end , intermediate between the two ends, a diffusion grid constituting the nozzle means is maintained and delimits an expansion chamber and a constituting chamber, the diffusion grid has a U or V-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 by virtue of the conical section extension of said chamber intended to cause an increase in the speed of Lement of the lateral gas flow, the combustion in the gas flow chamber 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 are provided with 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, in the case of using low or medium pressure gases, 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 in the lower sheet.
  • the burner 1 has two symmetrical half shells 2 and 3 fixed to each other by welding or any other known means, the end 4 is the cylindrical entry intended for s' fit and fit onto the fast-flowing gas flow supply duct, 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 a U-shaped section whose front part 11 1 is circular, the perforated sheets 9 and 10 have 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 sheet lower 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 formed by a single perforated sheet, in particular in the case of the use of high pressure gases, while for medium pressure gases 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 at high speed outside the chamber while promoting the attachment of the flame.
  • the expansion chambers 7 and combustion 8 may be of different shapes: in the shape of a parallelepiped, cylindrical, ovoid, etc., the shape of the grids 6 of section in the shape of U or V being adapted to match the shape of said chambers, in particular that of combustion.

Claims (6)

1. Brenner für Gasschweißanlagen mit hoher Strömungsgeschwindigkeit des Gasstromes, bestehend aus zwei miteinander verbundenen symmetrischen Halbschalen, die einenends einen verjüngten, streng auf die Gaszuleitung aufgepaßten Einlaßteil und andernends einen Auslaßteil bilden und einen zwischen Ein- und Auslaßteil angeordneten, innerhalb des Brennergehäuses eine Entspannüngs- von einer Brennkammer abgrenzenden, Düsenmittel bildenden Diffusorgitter, dadurch gekennzeichnet, daß das Diffusorgitter eine in U oder V Querschnittsform besitzt und über seitliche, zu den Innenflächen des Brennergehäuses geneigte Aussparungen mit diesem Düsenmittel bildet, die eine Beschleunigung des Gasstromes in den vom Gasstrom quer durchströmten Seitenbereichen und auch an der kreisrunden oder dreieckigen Frontseite des Diffusorgitters bewirken, wobei eine zusätzliche Beschleunigung der Strömungsgeschwindigkeit der seitlichen Gasströme durch eine entsprechende Verlängerung des konischen Teiles der Brennkammer ausserhalb derselben erfolgt, während die sich über die Frontseite des Diffusorgitters hin ausbreitende Flammfront innerhalb des Brennkammer bewirkt, daß sich die seitlichen Gasströme ausserhalb der Brennkammer entzünden können und somit die Zusammenfassung der Flamme insgesamt unterstützt wird.
2. Brenner nach Anspruch 1, dadurch gekennzeichnet, daß das Diffusorgitter eine in U oder V Querschnittsform und Aussparungen besitzt und daß die Gesamtoberfläche des Diffusorgitters wenigstens gleich groß, vorzugsweise größer als der Querschnitt der Auslaßöffnung der Brennkammer ist.
3. Brenner nach Anspruch 1, dadurch gekennzeichnet, daß das Diffusorgitter dem Druck des verwendeten Gases entsprechend aus einem oder zwei mit Ausnehmungen versehenen Blechen besteht, wobei bei Verwendung zweier Bleche diese im Frontbereich des Diffusorgitters zueinander deckungsgleich oder versetzt übereinanderliegend angeordnet sind, und wobei der Querschnitt der Ausnehmungen im oberen Blech wesentlich größer ist, als der Querschnitt der Ausnehmungen im unteren Blech, um ein Rückschlagen der Flamme zu unterbinden.
4. Brenner nach Anspruch 1, dadurch gekennzeichnet, daß das Diffusorgitter innherhalb des Brennergehäuses mittels seitlich auskragender, in in den Gehäuseseitenwänden vorgesehene Nuten eingreifender Verlängerungen seiner Seitenbereiche gehalten ist.
5. Brenner nach Anspruch 4, dadurch gekennzeichnet, daß die Einfügung der Verlängerungen der Seitenbereiche des Diffusorgitters in die Nuten des Brennergehäuses den Abstand der Seitenbereiche des Diffusorgitters von den Seitenwandungen des Brennergehäuses bestimmt.
6. Brenner nach Anspruch 1, dadurch gekennzeichnet, daß der Frontbereich des Diffusorgitters durch dessen Seitenbereiche verlängert ist und eine in U oder V, kreisrunde oder konische Querschnittsform bzw. eine konische Querschnittsform ohne Verlängerung durch Seitenwandbereiche ausweist.
