Definitions

  • the invention relates to a gas burner with several combustion heads.
  • combustion heads are inverted and the enclosure is divided into compartments between the walls of which air can circulate.
  • this does not describe an air circulation enclosure, but a separate supply by combustion head.
  • the air circulation enclosure is formed by a cover through which the pipes pass. gas inlet, a side casing provided with at least one air inlet cuff, and a base forming a support for all the combustion grids of the combustion heads while the walls forming the compartments are cylindrical and s 'extend from the cover to the base while providing a space for the passage of air in said compartments.
  • the burner includes a general gas supply to which the gas inlet pipes of the combustion heads are branched.
  • the gas inlet pipes are each provided with a solenoid valve so as to allow controlled ignitions of the various heads.
  • the invention makes it possible to design a burner easy to modulate in power, since it suffices to light the desired number of heads. In addition, starting is greatly facilitated since it is sufficient at the start to light a single head.
  • An advantageous embodiment of the invention is remarkable in that one of the combustion heads, called the ignition head, is provided with an ignition system and with a flame control system while the others so-called peripheral combustion heads are arranged around the ignition head in such a way that the combustion grids of the peripheral heads are each adjacent at least one location on the combustion grate of the ignition head so that the ignition of the peripheral heads is carried out by the flame of the ignition head and that it is therefore sufficient to light and control all the heads, of the only ignition system and of the only flame control system of said head d 'ignition.
  • a burner comprising two heads arranged side by side, an ignition head and a peripheral head, or an ignition head arranged in line between two peripheral heads, or even a central ignition head around which several peripheral heads are concentrically arranged.
  • the enclosure 1 is formed by a cover 3 (below in FIG. 3), a side wall 4, and a base 5 (FIG. 1).
  • enclosure 1 several compartments are arranged formed by spaced cylindrical walls, here two, 6a, 6b, which extend from said cover 3 towards the base 5 without touching it, and in each compartment is provided a combustion head. respectively 7a, 7b, called reverse.
  • Each head is, for example, of a type similar to that described in FR-A-2 593 270, if we consider only said head itself, each of them being, as already said, fitted in a separate and separate compartment.
  • Each combustion head comprises an annular combustion grid such as 8a and 8b for the heads 7a and 7b, the grids being fixed to the base 5.
  • each head has a mixing chamber such as 9a into which a gas inlet pipe 11a, 11b opens and which communicates by a chimney 10a with the space of the compartment of the head considered.
  • the pulsed air which arrives through the cuff 2 in a substantially tangential manner (FIG. 2) in the enclosure 1 will circulate around the walls 6a, 6b and between them, while it may pass below said walls bypassing their ends. free to reach into said mixing chambers such as chamber 9a.
  • the cover 3 has openings 12 and 13 for respectively an ignition electrode and an ionization flame control electrode which will be discussed below (not visible in FIG. 1 due to the cutting plane) and openings 14a, 14b for the passage of the aforementioned gas pipes.
  • the combustion head 7b provided with the ignition and flame control electrodes is hereinafter called the ignition head and the other head 7a, the peripheral head, these expressions being especially useful when there are more than two heads such as in the other embodiments which will be discussed below.
  • FIG. 5 shows an interesting distribution of gas on a burner of the type of that of the preceding figures provided with two combustion heads.
  • the gas comes from a general supply pipe 15 which arrives directly at the ignition head, therefore ending in the gas inlet pipe 11b and to which the gas inlet pipe 11a of the other head.
  • the pipe 11a is further provided with a solenoid valve 16.
  • the head 7b if the head 7b is supplied with gas and its ignition electrode is put into operation, said head 7b will light up and may light up by its vicinity the head 7a as soon as the solenoid valve 16 will be opened.
  • FIG. 6 shows an oblong envelope 1 ′ and diagrammatically shows an ignition head 7′b between two aligned peripheral heads 7′a and 7′c.
  • Figure 7 shows a circular envelope 1 ⁇ and shows schematically an ignition head 7 ⁇ b surrounded by four substantially concentric peripheral heads 7 ⁇ a, 7 ⁇ c, 7 ⁇ d and 7 ⁇ e.
  • the ignition heads 7′b and 7 ⁇ b are recognized by the passages for the ignition and flame control electrodes.
  • the head 7′a of FIG. 6 for example could be the ignition head and be the only one to have ignition and control electrodes insofar as it would be impossible to open the arrival of gas from head 7′c before that of head 7′b and closing the arrival of head 7′b before that of head 7′c.
