Abstract

The generator or projector has an ignition system comprising converters supplying two electrodes to generate electric arc between the electrodes that are spaced from each other. The system simultaneously generates another electric arc at the side of the former electric arc during the emission of a spray obtained from liquid hydrocarbon. Each electric arc is supplied independently by its own converter. An independent claim is also included for utilization of a flame generator or projector for the production of flames of large length for a show.

Description

DESCRIPTIONDESCRIPTION

L'invention se rapporte à un système d'allumage pour les générateurs ou projecteurs de flammes pour le spectacle qui sont construits suivant le procédé permettant de produire de flammes en enflammant un spray d'hydrocarbure.  The invention relates to an ignition system for generators or flame projectors for the show which are constructed according to the method for producing flames by igniting a hydrocarbon spray.

Les générateurs de flamme, construit suivant ce procédé présentent l'inconvénient d'être équipé d'un système d'allumage par un arc électrique qui est sensible à certaines conditions d'exploitation.  Flame generators, built according to this method have the disadvantage of being equipped with an ignition system by an electric arc that is sensitive to certain operating conditions.

Le principal inconvénient de ce système à un arc électrique est que le réglage de la distance d'écartement des deux électrodes de l'arc est souvent modifié de façon fortuite lors des manipulations de montage et de démontage qui sont consubstantielles à l'usage en spectacle dudit procédé et dès lors le système d'allumage à un arc présente des performances altérées en raison de ce mauvais réglage.  The main disadvantage of this system with an electric arc is that the adjustment of the spacing distance of the two electrodes of the arc is often modified fortuitously during the handling of assembly and disassembly which are consubstantial with the use in spectacle said method and therefore the arc ignition system has impaired performance due to this poor setting.

Un autre inconvénient est que ce réglage de la distance d'écartement des deux électrodes de l'arc se trouve modifié en raison d'une usure des électrodes et dès lors le système d'allumage à un arc présente des performances altérées en raison de ce mauvais réglage.  Another disadvantage is that this adjustment of the spacing distance of the two electrodes of the arc is modified due to wear of the electrodes and therefore the arc ignition system has impaired performance due to wrong setting.

Par ailleurs, i l arrive également que l'arc ne se forme pas parce q u e les électrodes sont isolées électriquement en raison de la présence entre leurs pointes d'une goutte d'humidité voire d'hydrocarbure.  Furthermore, it also happens that the arc is not formed because the electrodes are electrically insulated due to the presence between their tips of a drop of moisture or even hydrocarbon.

Enfin, en cas de stockage en extérieur en milieu humide, il peut se produire une perte de l'alimentation électrique en raison d'un courtcircuit dû à un défaut d'isolement des électrodes de l'arc électrique, ceci pouvant aller jusqu'à mettre irrémédiablement hors d'usage le transformateur alimentant les électrodes. T 2  Finally, in the case of outdoor storage in a humid environment, a loss of the power supply may occur due to a short circuit due to a lack of isolation of the electrodes of the electric arc, this being able to go up to irreparably put out of use the transformer feeding the electrodes. T 2

L'inventibn résout tous ces inconvénients en proposant un procédé d'allumage sécurisé qui consiste en l'ajout d'au moins un autre arc électrique à côté du premier arc électrique.  The invention solves all of these disadvantages by providing a secure ignition method which consists of adding at least one other electric arc next to the first electric arc.

La présente invention fournit un générateur ou projecteur de flammes et notamment des flammes de grande longueur pour le spectacle, utilisant un spray obtenu à partir d'hydrocarbures liquides et caractérisé par un système d'allumage composé de plusieurs arcs électriques.  The present invention provides a flame generator or projector and in particular flames of great length for the show, using a spray obtained from liquid hydrocarbons and characterized by an ignition system composed of several electric arcs.

De ce fait, on obtient la présence simultanée de plusieurs arcs électriques lo et l'on observe en cas de déréglage de l'écartement de deux électrodes la formation d'arcs supplémentaires en direction des électrodes des arcs mitoyens, ce phénomène étant alors à même de garantir la présence, d'un arc au moment de l'émission du spray d'hydrocarbure.  As a result, the simultaneous presence of several electric arcs lo is obtained and, in case of misalignment of the spacing of two electrodes, the formation of additional arcs in the direction of the electrodes of the adjoining arcs is observed. to guarantee the presence of an arc at the moment of emission of the hydrocarbon spray.

De plus, ce système permet de contourner les pannes d'allumage dues à 15 la rupture d'un transformateur puisque chaque arc est alimenté" indépendamment l'un de l'autre par son propre transformateur.  In addition, this system makes it possible to circumvent ignition failures due to the breakage of a transformer since each arc is supplied "independently of one another by its own transformer.
