Definitions

  • the invention relates to a gas burner, in particular for flaming or coating a surface.
  • the invention is therefore based on the object to provide an improved gas burner, in particular for the flame treatment and coating of surfaces.
  • An inventive gas burner for coating surfaces comprises a base body which surrounds a cavity. At least one fuel gas can be supplied to the main body. At least one metal foil stack can be used gas-tight in the base body.
  • the metal foil stack comprises at least two first metal foils and at least one second metal foil.
  • the first metal foil is formed comb-like with pointing to a gas outlet recesses and lands. From the main body at least fuel gas can be flowed into the partially projecting into the cavity metal foils.
  • traction metal foil stack is between in each case two first metal foils each inserted a second metal foil.
  • the webs of the first metal foils are each supported on the adjacent second film, which is continuous in the clamped area.
  • the main body On its side facing a surface to be fired or coated, the main body has a recess into which the metal foil stack is inserted in a gas-tight manner.
  • the fuel gas flows out through the recesses of the first metal foils.
  • the gas stream thus obtained is very homogeneous. Flaming or coating with the gas burner according to the invention takes place at a relatively short distance, in particular in a range from 1 mm to 20 mm.
  • the gas consumption compared to conventional gas burners is considerably reduced. The short distance causes flaming of the surface to occur, ignoring any thermal from both above and below.
  • the low energy consumption leads to a particularly low thermal load, so that the gas burner barely warps.
  • the required effort for the discharge of exhaust gases is reduced, since correspondingly less.
  • the achieved short flames are less prone to disturbing air currents.
  • the Ausström characterizing of the gas burner can be influenced by the number of first and second metal foils in the metal foil stack, the width and arrangement of the recesses and the geometry of the webs of the first metal foil. Preferably, a number n of first metal foils and a number n-1 of second metal foils are provided. By removing the metal foil stack and separating it into the individual metal foils, it can be cleaned particularly easily in comparison with conventional compact burners. A scaling of the burner according to the invention to a desired length, width and shape is structurally possible in a simple manner. The simple structure results in low production costs.
  • the second metal foil in the region projecting into the cavity has a slot through which at least fuel gas can flow between the recesses of the adjacent first films.
  • the supply of further lying inside first films with fuel gas only on the slots of intermediate second films is possible.
  • the homogeneity of the flame increases the use of the slot.
  • the metal foil stack can be clamped between two solid retaining cheeks, which can be inserted gas-tight into the base body.
  • the retaining cheeks are in particular screwed together and designed so that they do not deform under heat as possible.
  • the retaining cheeks form with the metal foil stack easy to insert into the body and exchangeable module.
  • the retaining cheeks can either clamp only a part of the metal foil stack in the vicinity of the gas outlet, while a protruding into the cavity part of the metal foil stack remains free.
  • the retaining cheeks may also each have an opening which allows lateral inflow of the fuel gas into the metal foil stack.
  • a particularly high homogeneity of the exiting flame is achieved if the recesses of adjacent, separated from a second metal foil first metal foils are each offset from each other.
  • the offset in two first metal foils may be designed such that always one ridge of a first metal foil is adjacent to a center of a recess of the other first metal foil.
  • the recesses and / or the elongated hole are preferably produced by means of laser cutting, since such a burr formation is prevented, which can lead to undesired turbulence.
  • the sides of the metal foils facing the gas outlet and / or the retaining cheeks and / or the base body are preferably correspondingly shaped, so that no inhomogeneities of the coating result.
  • the metal foils and / or the retaining cheeks are preferably formed of brass and / or stainless steel, since these materials oxidize or deform only slightly under the action of heat.
  • the metal foils each have a thickness of at most 1 mm.
  • the gas burner is used for coating, preferably at least one precursor can be supplied to the main body and can be flowed out of the recesses.
  • the good homogenization of the fuel gas in the gas burner also causes a correspondingly homogeneous distribution of the precursor in the fuel gas, which in turn leads to a homogeneous coating.
  • FIG. 1 shows a metal foil stack 1 with two first metal foils 2.1, 2.2 and a second metal foil 3 for a gas burner 4, the in FIG. 2 will be shown.
  • FIG. 1a shows the first metal foil 2.1, which is formed comb-like with webs 5 of the width y and intervening recesses 6 of the width x.
  • the first metal foil 2.2 is also comb-like with webs 5 and recesses 6 of corresponding width x, y formed, but webs 5 and recesses 6 are each offset by a width .DELTA.x relative to those of the first metal foil 2.1.
  • Figure 1c shows a second metal foil 3, which is provided with a slot 7.
  • a module 8 is shown with a formed from the first metal foils 2.1, 2.2 and the second metal foil 3 metal foil stack 1, which is held together by two solid retaining cheeks 9 non-positively.
  • the second metal foil 3 lies between the two first metal foils 2.1, 2.2.
  • FIG. 2a is a cross-sectional view of the gas burner 4 with a module 8 shown in FIG. 2b a corresponding perspective view of the module 8.
  • a cavity 10 enclosing the base body 11 has in the direction of a gas outlet (above) on a recess into which the module 8 is inserted gas-tight.
  • the retaining cheeks 9 are screwed together and fix and thereby clamp the intermediate metal foil stack 1 positively and non-positively.
  • an opening 12 is laterally provided, can flow through the fuel gas in the recesses 6 of the first metal foils 2.1, 2.2.
  • a gas exchange between the recesses 6 is possible in the region of the slot 7.
  • the fuel gas flows upward from the recesses 6.
  • the fuel gas may be added to a precursor or another layer-forming substance.
  • first metal foils 2.1 to 2.n can be provided in a metal foil stack 1 more than two first metal foils 2.1 to 2.n and more than a second metal foil 3.
  • a number n of first metal foils 2.1 to 2.n and a number n-1 of second metal foils 3 are provided and arranged alternately.
  • the arrangement of first metal foils 2.1 to 2.n can also be done with a different offset or without offset.
  • the frictional cohesion of the metal foils 2.1 to 2.n, 3 in the metal foil stack 1 can be supported by a positive connection.
  • the assembly can be facilitated by means of the metal foils 2.1 to 2.n, 3 inserted pins or screws.
  • the recesses 6 and the elongated holes 7 are preferably produced by means of laser cutting.
  • the metal foils 2.1 to 2.n, 3 and / or the retaining cheeks 9 are preferably formed of brass or stainless steel.
  • the thickness of the metal foils 2.1 to 2.n, 3 is preferably at most 1mm.
  • the gas outlet side of the metal foils 2.1 to 2.n, 3 and / or the retaining cheeks 9 and / or the base body 11 may be designed to be odd according to a non-planar surface to be coated or flamed.
  • the metal foil stack 1 can alternatively be tensioned directly in the main body 11 without the use of retaining cheeks 9.
