Definitions

  • Bricks with liquefied petroleum gas, such as butane, are well known and in common use.
  • the oxidation reaction of the gas which enters the air in the form of a jet gives a colored hot zone which is commonly known as a flame.
  • This flame has the disadvantage of not resisting drafts and the use of these lighters is difficult outdoors, as soon as there is a little wind.
  • the object of the present invention is to make the combustion gases visible again. It consists in introducing into the path of the gases at high temperature, in an area close to the combustion reaction, a substance releasing metal ions under the influence of heat, so as to color these gases and obtain a visible flame.
  • the invention relates to gas burners, in particular burners intended to be used as cigarette lighters or lighters.
  • the burner according to the invention is supplied with gas and comprises means for controlling the flow of gas, a combustion chamber opening into the open air and an air-gas mixing device opening into the combustion chamber.
  • the aim is achieved by the fact that the burner comprises a salt placed on the passage of the combustion gases and capable of coloring them.
  • the metal ion donating substance can be placed either directly on a part of the wall of the combustion chamber, or on a support penetrating into the gas stream.
  • the gas from a reservoir is brought to a burner by a pipe 1 ending in a nozzle 2 directed towards a combustion chamber 3.
  • the chamber 3 has a wall frustoconical 4 whose section decreases as it approaches the duct 1 and this chamber ends in a tubular inlet channel 5 situated opposite, but at a distance from, the nozzle 2. In this way, the gas flow s' escaping through the nozzle 2 causes combustion air into the chamber.
  • the ignition is obtained by sparking a spark between two electrodes 8 and 9.
  • the inner wall of the chamber 3 has two ribs 10 covered with a deposit 11 of a salt capable of coloring the combustion gases. Inside the combustion chamber there are still two deposits 12 of a salt which may be the same or different from that constituting the deposits 11. Chamber 3 is made of ceramic and withstands very high temperatures.
  • the assembly is dimensioned in such a way that the combustion reaction takes place inside the combustion chamber 3, the hot burned gases escaping through the open end of the chamber. During this reaction, very large amounts of heat are produced which heat the walls of the combustion chamber. Under the effect of heat, the deposits 11 and 12 release metal ions which color the gases escaping from the combustion chamber.
  • the chamber 3 is constituted by a metal socket, so that the electrode 9 is deposited in an insulating sleeve 13.
  • the diffuser 6 has a slightly different shape from that shown in Figure 1, but plays exactly the same role.
  • the chamber 3 has a transverse support 14 which is constituted by a sleeve of refractory material, for example ceramic.
  • a metal wire 15 passes inside this sleeve and the ends of this wire are bent.
  • This wire constitutes a metal frame for the sleeve 14, so that in the event of the latter breaking, for example following an impact, the sleeve 14 is held in position by this frame.
  • the sleeve 14 constitutes a support for a deposit 16 of a salt constituting a substance emitting metal ions for coloring the combustion gases.
  • the metal frame could consist of several wires 15.
  • the sleeve 14 could also be replaced by a metal rod or by an alumina rod or by a support of different shape, for example a lattice in the shape of a forced disc inside the chamber 3.
  • the burners described can be suitable both for a lighter of the lighter type, in which the duct 1 is secured to a tank of liquefied gas, and to a heating nozzle connected by a flexible pipe to a tank. liquefied gas.
  • salts make it possible to color the hot gases escaping from the burner and excellent results have been obtained, in particular when the salt is a compound of sodium, lithium, strontium, potassium or copper or when the salt is mixed with a metal oxide or a metal carbide.
  • the support itself constitutes the ion-emitting salt, in particular when this support consists of a glass rod.
  • the support could be constituted by a platinum wire, a metal oxide, a metal carbide or a metal nitride or also by a porous ceramic and / or based on alumina.
