Definitions

  • the present invention relates to improvements to a gas burner of the premix type and flame control.
  • This type of burner is commonly used in industry, allowing in particular high heating powers per unit area.
  • the gas burner of the premix and flame control type according to the invention is of the type comprising an arrival of the air + fuel gas premix in a distribution chamber opening out through a flame stabilization grid in a combustion chamber.
  • Various works have been carried out on this type of burner, and one can cite in particular French patent N ° 69.37574 of October 31, 1969 filed in the name of the same applicant for a "gas burner with high heating power".
  • this patent we were essentially targeting specific industrial applications such as the welding of large diameter pipes, sheet metal processing, etc.
  • the invention relates, on the contrary, in a more particular way.
  • the object of the invention is to solve the above-mentioned difficulties.
  • said cell in order to facilitate control of the flame by subtracting the control cell from the thermal stresses linked to the operation of the burner, said cell is placed behind said distribution chamber behind said stabilization grid. of flame with respect to the direction of flow of the combustible mixture, "Reading"
  • the operating conditions
  • the reading cell is in fact protected by the distribution grid and by the distribution chamber interposed between it and said grid. Furthermore, this arrangement allows the cell to be easily arranged when the burner is intended to equip an immersed tube. outside the heating bath.
  • the cell is placed behind a nozzle whose axis is directed substantially perpendicular to said flame stabilization grid, said nozzle communicating through an orifice in said distribution chamber, and a supply of secondary air under pressure opening into said tip.
  • additional cooling is ensured in the vicinity of said reading cell, which is therefore effectively effectively subtracted from the thermal constraints of operation of the burner.
  • an ignition electrode is mounted through said distribution chamber opening out by its electrode suitably electrically isolated through said stabilization grid and by its head connected to the power supply behind said chamber distribution.
  • the invention also applies to the use of burners adapting to a combustion chamber.
  • FIG. 1 schematically shows partly in section, partly in external view and with cutaway, a gas burner in accordance with the invention
  • Figure 2 shows on a smaller scale an assembly diagram of the burner.
  • the burner identified as a whole 1 essentially comprises a distribution chamber 2 into which arrives by a supply line 3 the air / combustible gas premixing advantageously opening into the chamber through an opening substantially tangential 4.
  • Chamber 2 which has the general shape of a cylindrical box with substantially circular section is closed on its front face by a flame stabilization grid 5.
  • This grid can be of the type described in the aforementioned French patent No. 69.37574, essentially comprising orifices of suitable diameters and distribution to ensure good hooking and good stabilization of the flames at the inlet of the combustion chamber 6 and this for the considered powers of operation of the burner.
  • the box forming the distribution chamber is closed by a wall 7.
  • the letters "front” and “rear” of the burner have been identified by the letters AV and AR, with reference to the circulation of the mixture. fuel in the burner as shown by the arrows.
  • the ignition of the burner is ensured by an electrode 8 supplied with a suitable high voltage as shown in diagram 9 and suitably isolated, the ignition being carried out by sparks between the tip 10 of the ignition electrode and the. wall next to the metal front flange 11 suitably grounded in the box forming the distribution chamber 2.
  • a flame control cell 12 radiation-sensitive ultra-vio let a flame and "reading" the information through .. orifices of the flame stabilization grid 5.
  • the cell 12 is placed behind a nozzle 13 whose axis 14 is directed substantially perpendicular to the flame stabilization grid 5, said nozzle communicating through an orifice in the distribution chamber 2.
  • the burner is supplied with combustible gas by a pipe 18 and with main air by a pipe 19, the premix being thus delivered to the pipe 3 under substantially stoichiometric conditions.
  • the air is supplied by a fan or compressor 20 which supplies not only the main air duct 19 but also the secondary air duct 16, the connections being thus made that the secondary air inlet pressure in the nozzle 13 will be greater than that of the arrival of the premix in the distribution chamber 2, so as to obtain the sweeping and cooling of the nozzle 13 by the secondary air flow arriving at 17 as desired.
  • the cell 12 is connected to the burner operating programmer 21 which controls the ignition electrode 8 the fan 20 and the controlled gas inlet valve 23 by suitable connections.
  • the distribution chamber can optionally be provided with additional grids for homogenization and suitable distribution of the premix, as indicated for example in 27.
  • a torch or an auxiliary burner can optionally be used for igniting the burner which can be arranged for example in the axis of the burner or on the combustion chamber itself on which the burner is fixed.
