Definitions
- the invention relates to a gas burner of the premix and flame control type.
- This category of burner is in common industrial use.
- the gas burner of the premix and flame control type according to the invention is, more specifically, such that it includes an air and combustible gas premix inlet in a distribution chamber opening out through a stabilization grid. flame in a combustion chamber where the premix is ignited by means of an ignition electrode.
- Another means of controlling the operating conditions and combustion of the flame has already been envisaged and is used. It consists of the provision of an ionization electrode placed at the level of the combustion chamber.
- Such an electrode placed in the space where the flame must develop in normal operating condition, makes it possible to detect the actual combustion conditions and to effectively control the position of this flame. It thus allows the burner to be stopped in the event of excessive instability or an abnormal flame position.
- the water heater burners have only a low heating power.
- the thermal stress problems are therefore not comparable.
- the problems of flame instability resulting from large pressure fluctuations caused by the combustion of a high power flame in a compact medium do not exist.
- the ionization electrode when it was provided, likewise elsewhere than the ignition electrode, were arranged so that their body and their head, connected to the electrical supply, were placed away from the flow of the gas mixture; only their donut point in the mixture.
- the invention provides a gas burner of the premix type, with a grid. and flame control, comprising an ionization electrode mounted, like the ignition electrode, through the flame stabilization grid, these two electrodes being arranged, on the one hand, with their tips properly insulated, respectively straight , and bent towards the grate, extending into the combustion chamber and, on the other hand, with their heads each connected to a corresponding suitable electrical supply, passing through the distribution chamber.
- the invention also applies to the use of burners adapting to a combustion chamber and compact submerged tube assembly.
- the burner identified as a whole 1 comprises essen tially a distribution chamber 2 into which arrives, by a supply line 3, the air / combustible gas premix, advantageously opening into chamber 2 through a substantially radial opening 4.
- Chamber 2 which has the general shape of a cylindrical box with a substantially circular section is closed, on its front face, by a metal flame stabilization grid 5.
- This grid which is therefore relatively sensitive to thermal stresses (compared to ceramic plates) under certain operating conditions of the burner may in particular be of the type described in the above-mentioned French application no. 83 09468. More specifically, it will include orifices of suitable diameter and distribution to ensure good attachment and good stabilization of the flames at the entrance to the combustion chamber 6 , and this for the considered operating powers of the burner.
- the box forming the distribution chamber 2 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 fuel mixture in the burner as shown by the arrows.
- the ignition of the burner is ensured by an electrode 8 supplied with high voltage suitable as shematized at 9 and suitably isolated, the ignition taking place by sparks between the curved tip 10 ⁇ of the ignition electrode and the wall next to the grid 5 or the metal front flange 11 on which the grid 5 is fixed and which is grounded to the box forming the distribution chamber 2.
- an ionization electrode 12 is also provided, also supplied under suitable voltage as shown in diagram 10 and suitably isolated, the flame development conditions being detected between the tip 13 of the electrode 12 and the neighboring mass of the grid 5.
- the tip 13 of the ionization electrode 12 is, as illustrated, substantially straight and directed substantially parallel to the direction of flow of the gas mixture.
- the two electrodes 8 and 12 are mounted, also substantially parallel to the direction of flow of the fuel mixture, so as to pass through the flame stabilization grid 5 towards the central part thereof and with their respective points 10 and 13 s extending into the combustion chamber.
- the electric power cables 9 and 10 of the electrodes extend, as illustrated, in the distribution chamber 2 and pass through the wall of the latter, sealingly at the operating pressures considered, at 14 and 15. Sealing can in particular be ensured by cable glands.
- the burner is supplied with combustible gas via a pipe 16, the premix being thus delivered to the pipe 3 under substantially stoichiometric conditions.
- the air necessary for combustion is supplied by a fan or compressor 17 which supplies the main air duct 18.
- the fan is supplied with electrical energy by 24.
- the burner described above makes it possible to equip installations with immersed tubes (or more generally with a combustion chamber immersable in the liquid 19 to be heated) of particularly compact construction.
- the shutdown of the burner is controlled by the ionization electrode 12 as soon as the latter detects an absence of flame.
