Definitions

  • the present invention relates to a burner / generator of hot air with internal ignition.
  • gas burners of intrinsically cold nozzle type capable of performing external combustion of a gas mixture at high speed.
  • burners of this type frequently apply to the low temperature heating of plastic film, for example polyethylene film, with a view to their retraction by means of a gaseous flow coming from the combustion of a combustible gas.
  • a gaseous flow coming from the combustion of a combustible gas such as propane and air.
  • the burner must therefore be designed to produce a gas flow having a temperature of about 120 ° to 540 ° C at a predetermined distance from the burner (distance at which the plastic film to treat must be arranged).
  • the temperature must be relatively homogeneous and the gas stream free of burning material, so as to avoid any possibility of burning, scorching and blistering of the film.
  • the diffusion means can be made from a mesh or a perforated sheet.
  • the tubular housing of the candle forms a cavity generating a turbulent regime of the gas flow emitted by the perforations of the grid.
  • a permanent self-sustaining combustion of the gas flow can be established at this cavity, causing a heating of the wall of the ignition chamber, which is contrary to the purpose.
  • an ignition device involving an ignition cavity external to the ignition chamber, and communicating with it through a reduced section passage orifice provided in the wall the ignition chamber substantially to the right of the front region of the gate, the section of this orifice being provided sufficiently small to ensure that the disturbances of the gaseous mixture flow at this orifice can not generate a focus of Parasite combustion self-maintenance likely to heat the wall of the ignition chamber.
  • this solution has a disadvantage resulting from the fact that, during ignition, the generated spark causes a sudden combustion of the gaseous mixture in the ignition chamber. The gases in combustion are ejected and then come on the flow of gas mixture coming out of the central perforations of the burner grate. This is a noisy and unpleasant solution for the operator and for those around him.
  • a major problem that must be solved in the design of a direct ignition device is that of the voltage and energy of the electrical pulses that should be applied to the electrodes d ignition, to effectively ignite the gas mixture flowing at high speed inside the burner.
  • the gap between the electrodes must be relatively large. This voltage and this instantaneous energy must therefore be relatively high so that it is appropriate to use, on the one hand, a sufficiently powerful generator and, on the other hand, an electrical connection between the generator and the electrodes which is particularly well isolated so as to avoid online losses or disruptions.
  • the object of the invention is therefore more particularly to eliminate all these disadvantages.
  • a cold nozzle gas burner of the aforesaid type in which single or multiple diffusion means comprise a central orifice into which an ignition chimney extends which extends axially inside the chamber. pressure recovery, this ignition chimney defining an ignition chamber provided with ignition electrodes in communication with the burner pressure recovery chamber through a calibrated orifice.
  • the spark generated between the ignition electrodes causes the gaseous mixture to ignite without igniting inside the ignition chamber, and a combustion that propagates axially to the combustion chamber of the burner thus causing ignition of the burner.
  • the tubular ignition chamber may be extended at one of its ends by a minimum cross-section chimney to prevent any backfire but nevertheless allow the propagation of the gas mixture during combustion for ignition , and the other end may be closed by a sleeve of insulating material provided with a coaxial ignition electrode.
  • This electrode cooperates with at least one annular portion of the body made of an electrically conductive material which constitutes a second ignition electrode surrounding the first.
  • the burner previously described may be designed so as to be equipped with an extension consisting of a tubular element, possibly telescopic can be inserted between the nozzle of the injection device and the burner head.
  • the invention therefore also aims to solve these problems.
  • an additional grid or sieve whose mesh is smaller than that of the diffusion grid but whose total passage section (sum of the sections of all the meshes) is superior to those of the means of diffusion so as to avoid a return of flames inside extender without causing a noticeable slowdown of the gas flow.
  • this additional grid may be permanently disposed within the pressure recovery chamber, against or in the immediate vicinity of the diffusion means.
  • this additional grid may be arranged between the two diffusion grids.
  • the capacity of the capacitor formed between the conductor and the extender remains within the limits of the acceptable, given the performance of the ignition device described above.
  • the oblique part of the driver causes a progressive disturbance gas flow over the entire length of the extender, and over its entire section. This disturbance, which makes it possible to obtain a homogeneous gaseous mixture, does not, however, cause a noticeable slowing down of the gaseous flow, and this, because of its progressivity along the oblique portion of the conductor.
  • the electrical conductor may be made of at least two rigid elements, one of these two elements being tubular while the other consists of a cylindrical rod which engages tightly in the element tubular. These two elements have at least partially the same oblique.
  • the burner according to the invention comprises an injection device 1 adapted to transmit to the burner head 2, a combustible gas mixture stream.
  • This device therefore forms a jet pump which drives the air coming from the opening 7 and generates in the convergent portion 4 of the tubing 3 (point I) a flow of gaseous mixture at high speed, of the order of 12 660 meters / minute.
  • the burner head 2 of tubular form, consists of two electrically conductive metal parts, which successively delimit a pressure recovery chamber 10 which connects to the tubing and an ignition chamber 11 which opens to the outdoors.
  • the pressure recovery chamber 10 has beyond its connection zone to the pipe 3, a flared shape delimited by two converging walls 12, 13, of increasing width and two diverging side walls 14, 15 of decreasing width. As this is visible on the figures 2 and 3 , the front edges 16, 17 of the two convergent walls 12, 13 have coaxial circular shapes.
  • the ignition chamber 11 has a shape also flared. However, in this example, it is delimited by two parallel walls 18, 19 which extend the two converging walls 12, 13, and two diverging side walls 20, 21 which extend the side walls 14, 15, respectively in the same orientations.
  • the front edges 22, 23 of the two walls 18, 19 are circular and extend coaxially with the borders 16, 17.
  • a double diffusion grid 24 which consists of two pieces of perforated sheet having the shape of a toric sector of substantially semicylindrical section, and whose large radius of curvature corresponds substantially to that of the front edges 16, 17 of the converging walls 12, 13.
  • the perforated plate, pressure recovery chamber side 10 has in its center a long and narrow oblong cutout.
  • the walls 18 and 19 of the ignition chamber 11 are extended by two circular deflectors 30, 31 which converge substantially towards one another and have two coaxial respective edges 32, 33 forming between them a passage space of width less than the width of the lateral sides 20, 21 of the ignition chamber 11.
  • the fuel mixture forms a succession of jets again accelerated (point N at 2400 m / min, figure 2 ).
  • these jets are oriented axially while in the lateral parts, they are substantially radial and abut on the walls 18, 19 and on the baffles 30, 31.
  • the speed of the gas flow is not homogeneous, which should, in principle, lead to a heterogeneity of the flame.
  • deflectors 30, 31 which serve to deflect the fuel mixture flow zones from the side portions of the grid 24 and to make them slightly converge towards the central region of the gas flow.
  • this ignition device involves a cylindrical ignition chamber 43 which extends coaxially with the head 2 of the burner inside the pressure recovery chamber 10 via a ignition chimney 44 which passes through the double perforated grid 24 in its center and opens into the ignition chamber 11 while in the other end of the ignition chamber, engages an insulating tubular sleeve 41 bore floor in which is disposed a cylindrical ignition electrode 42 having three successive steps 42 ', 42 ", 42"' corresponding to the steps of said bore.
