Definitions

  • Self-evaporating burners in which the fuel is heated beforehand by indirect heat exchange with the burner flame, have, by the fact that the burner body acts as a heat exchanger, ratios of total length / diameter of the around 2; if such a ratio favors compactness, it leads to a certain number of drawbacks: unstable flame, impossibility of using high primary vents, very difficult ignition by electrode, requiring the use of expensive additional devices.
  • the invention relates to a burner according to claim 1. Improvements are defined in the dependent claims.
  • the burner comprises a tube in which is mounted an obstacle creating a zone of turbulence and the ignition electrode is mounted so as to make spark a spark in the turbulence zone.
  • the disturbing device may consist of a heat resistant ball with a diameter of 5 to 10 mm placed 55 mm from the bottom of the burner with a diameter of 52 mm and a length of 95 mm - the distance being taken when the mixture arrives in the burner, the electrode being placed approximately 5 mm from the walls in the turbulent zone established at approximately 65 mm from the bottom of the burner.
  • the obstacle is shaped so as to give the side wall of the burner a flat flame.
  • FIG. 1 is a diagram of a burner according to the invention
  • the burner shown in FIG. 1 comprises an accumulator 1 which can be constituted by the battery of a carrier vehicle and which supplies, via a switch 2, in parallel the coil 3 of a solenoid valve 4, and an igniter consisting successively of an oscillator 5, a power stage 6 and a step-up transformer voltage 7.
  • the solenoid valve 4 is placed on the pipe 8 supplying the fuel to a burner 9. Although this is not shown in the figure, the fuel first passes through a jacket along the body 9 of the burner before entering the burner body.
  • the transformer 7 supplies a conductor 10 with an electrode 11 for igniting the burner.
  • a steel ball 12 of 5 mm diameter placed 55 mm from the bottom of the burner, which has a diameter of 52 mm and a length of 95 mm.
  • the electrode is placed approximately 5 mm from the walls in the turbulence zone established approximately 65 mm from the bottom of the burner.
  • switch 2 When switch 2 is open, the whole system is at rest. Fuel is not sent to the burner and the ignition device does not work. But as soon as the switch 2 is closed, fuel arrives at the burner and it is ignited by the electrode 11, the ignition operations being carried out continuously as long as the switch 2 is closed at a time interval a tenth of a second.
  • FIG. 2 shows a burner in which the body 13 is rectangular and defines with the ball 14 relatively flat intervals so that the flames which exit from the burner are in the form of a veil.
  • Figure 3 which is a sectional view of a burner, we recognize the ball 12 and the body 9 of the burner. There is also provided a secondary air inlet 15 and an ionization control electrode 16 which makes it possible to verify that the combustion is well established and if not to provide corrective actions such as closing the supply.
