Description
L'invention concerne un brûleur à gaz du type à prémélange et à contrôle de flamme.The invention relates to a gas burner of the premix and flame control type.
Cette catégorie de brûleur est d'utilisation industrielle courante.This category of burner is in common industrial use.
Le brûleur à gaz du type à prémélange et à contrôle de flamme conforme à l'invention est, de façon plus spécifique, tel qu'il comporte une arrivée de prémélange air et gaz combustible dans une chambre de répartition débouchant par une grille de stabilisation de flamme dans une chambre de combustion où le prémélange est enflammé au moyen d'une électrode d'allumage.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.
Divers travaux ont été menés en vue de résoudre les problèmes consécutifs à l'allumage de tels brûleurs et au contrôle de la flamme qui se développe.Various works have been carried out with a view to solving the problems resulting from the lighting of such burners and the control of the flame which develops.
A ce sujet, on peut notamment citer la demande de brevet français n° 83 09468 du 8 Juin 1983 déposée au nom du même demandeur pour un "brûleur à gaz du type à prémélange et à contrôle de flamme, utilisé en particulier pour une installation à tube immergé".On this subject, one can quote in particular the French patent application n ° 83 09468 of June 8, 1983 filed in the name of the same applicant for a "gas burner of the premix type and with flame control, used in particular for an installation with submerged tube ".
Les domaines industriels auxquels s'appliquent le brûleur objet de cette demande et le brûleur de l'invention sont voisins. Les problèmes spécifiques rencontrés sont comparables.The industrial fields to which the burner which is the subject of this application and the burner of the invention apply are similar. The specific problems encountered are comparable.
Dans la demande précédente en question, on prévoyait de contrôler les conditions de fonctionnement ou de combustion de la flamme au moyen d'une cellule de contrôle sensible au rayonnement ultraviolet. Cette cellule était disposée vers le fond d'un embout qui s'étendait, par rapport à la direction d'écoulement du mélange gazeux, à l'arrière de la chambre de répartition. Un faible débit d'air débouchant dans l'embout assurait un refroidissement complémentaire de la cellule. De cette façon, la cellule de contrôle de la flamme était soustraite aux contraintes thermiques particulièrement élevées dans ce type de brûleur travaillant en milieu immergé avec une chambre de combustion compacte.In the previous application in question, it was planned to control the operating or combustion conditions of the flame by means of a cell control sensitive to ultraviolet radiation. This cell was arranged towards the bottom of a nozzle which extended, with respect to the direction of flow of the gas mixture, at the rear of the distribution chamber. A low air flow opening into the nozzle provided additional cooling of the cell. In this way, the flame control cell was subtracted from the particularly high thermal stresses in this type of burner working in an immersed environment with a compact combustion chamber.
Cependant, un tel contrôle de flammes par une cellule ainsi disposée peut, dans certains cas, ne pas être approprié.However, such flame control by a cell thus arranged may, in certain cases, not be appropriate.
Des problèmes peuvent se poser, en particulier en cas de retour de flamme, c'est-à-dire dans le cas où, suite notamment à des instabilités de flamme consécutives à des fluctuations de pression, la flamme, au lieu de brûler dans la chambre de combustion, se développe accidentellement dans la chambre de répartition. En effet, la position occupée par la cellule, en arrière de la chambre de répartition, lui permet de continuer à observer l'existence de la flamme et donc à autoriser le fonctionnement normal du brûleur, sans détecter la position anormale de cette flamme dans la chambre de répartition, ce qui peut entraîner des contraintes thermiques excessives pouvant conduire à la destruction de la grille de stabilisation de flamme, endommageant par là même le brûleur.Problems may arise, in particular in the event of a flashback, that is to say in the case where, following in particular flame instabilities following pressure fluctuations, the flame, instead of burning in the combustion chamber, accidentally develops in the distribution chamber. Indeed, the position occupied by the cell, behind the distribution chamber, allows it to continue to observe the existence of the flame and therefore to authorize the normal operation of the burner, without detecting the abnormal position of this flame in the distribution chamber, which can lead to excessive thermal stresses which can lead to the destruction of the flame stabilization grid, thereby damaging the burner.
En outre, la nécessaire protection thermique que l'on doit assurer à la cellule de contrôle, en liaison avec la compacité du brûleur, requiert, en général, une conception du brûleur assez complexe, pouvant entraîner des surcoûts de fabrication et des problèmes de standardisation.In addition, the necessary thermal protection which must be provided to the control cell, in conjunction with the compactness of the burner, generally requires a fairly complex burner design, which can lead to additional manufacturing costs and standardization problems. .
Un autre moyen de contrôle des conditions de fonctionnement et de combustion de la flamme a déjà été envisagé et est utilisé. Il consiste en la prévision d'une électrode d'ionisation mise en place au niveau de la chambre de combustion.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.
Une telle électrode, disposée dans l'espace où doit se développer la flamme en condition normale de fonctionnement, permet de détecter les conditions réelles de combustion et de contrôler effectivement la position de cette flamme. Elle permet ainsi de commander l'arrêt du brûleur en cas d'instabilité excessive ou de position anormale de la flamme.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.
Cependant, il est à noter que ce type de contrôle par électrode d'ionisation était jusqu'à présent utilisé sur des brûleurs (brûleurs à plaquette céramique, brûleurs de chauffe-eau) présentant des conditions de fonctionnement tout à fait différentes de celles du brûleur à prémélange et à grille de stabilisation de flamme de l'invention.However, it should be noted that this type of control by ionization electrode has hitherto been used on burners (ceramic plate burners, water heater burners) having entirely different operating conditions from those of the burner. with premix and flame stabilization grid of the invention.
Les brûleurs de chauffe-eau n'ont qu'une faible puissance de chauffe. Les problèmes de contraintes thermiques ne sont donc pas comparables. Les problèmes d'instabilité de flamme consécutifs à de fortes fluctuations de pression engendrées par la combustion d'une flamme de forte puissance en milieu compact, n'existent pas.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.
Dans les brûleurs à plaquette céramique, la flamme est "rentrante" et se développe das la plaquette. Les conditions de fonctionnement et le domaine d'application sont là encore différentes de celles du brûleur de l'invention.In ceramic plate burners, the flame is "reentering" and develops in the plate. The operating conditions and the field of application are again different from those of the burner of the invention.
On remarquera, par ailleurs, que de façon à éviter d'interférer avec l'écoulement du mélange gazeux et à ne pas perturber les conditions de fonctionnement du brûleur, l'électrode d'ionisation, lorsqu'elle était prévue, de même d'ailleurs que l'électrode d'allumage, étaient disposées de façon que leur corps et leur tête reliée à l'alimentation électrique soient placées à l'écart de l'écoulement du mélange gazeux ; seule leur pointe beignant dans le mélange.It will also be noted that, in order to avoid interfering with the flow of the gas mixture and not to disturb the operating conditions of the burner, 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.
Au contraire, dans l'invention, et de façon surprenante, on s'est aperçu que prévoir l'électrode d'ionisation et l'électrode d'allumage directement au sein du mélange gazeux sur la grille de stabilisation de flamme d'un brûleur dans lequel les problèmes d'instabilité de flamme sont particulièrement délicats à résoudre, n'entraînait aucune perturbation pouvant nuire au bon fonctionnement du brûleur.On the contrary, in the invention, and surprisingly, it has been found that providing the ionization electrode and the ignition electrode directly within the gas mixture on the stabilization grid flame of a burner in which the problems of instability of the flame are particularly difficult to solve, did not cause any disturbance which could affect the proper functioning of the burner.
C'est pourquoi, compte tenu des nombreux avantages offerts au niveau du contrôle de la flamme par l'électrode d'ionisation, et qui ont été rappelés ci-avant, l'invention prévoit un brûleur à gaz du type à prémélange, à grille et à contrôle de flamme, comprenant une électrode d'ionisation montée, comme l'électrode d'allumage, à travers la grille de stabilisation de flamme, ces deux électrodes étant disposées, d'une part, avec leurs pointes convenablement isolées, respectivement droite, et recourbée vers la grille, s'étendant dans la chambre de combustion et, d'autre part, avec leurs têtes reliées chacune à une alimentation électrique correspondante adaptée, traversant la chambre de répartition.This is why, in view of the numerous advantages offered in terms of flame control by the ionization electrode, and which have been recalled above, 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.
De cette façon, on assure un bon contrôle de la position et des conditions de combustion de la flamme, permettant d'éviter, notamment, toute extinction intempestive du brûleur en cours de combustion et tout endommagement de celui-ci consécutif à une instabilité ou retour de flamme.In this way, good control of the position and combustion conditions of the flame is ensured, making it possible to avoid, in particular, any untimely extinction of the burner during combustion and any damage to it as a result of instability or return. of flame.
L'invention s'applique également à l'utilisation de brûleurs s'adaptant à un ensemble chambre de combustion et tube immergé compact.The invention also applies to the use of burners adapting to a combustion chamber and compact submerged tube assembly.
L'invention, ses caractéristiques et avantages apparaîtront plus clairement à l'aide de la description qui va suivre faite en référence aux dessins annexés dans lesquels :
- - la figure 1 montre, de façon schématique, un brûleur à gaz conforme à l'invention, et
- - la figure 2 illustre à plus petite échelle un schéma de montage du brûleur.
- FIG. 1 schematically shows a gas burner according to the invention, and
- - Figure 2 illustrates on a smaller scale an assembly diagram of the burner.
En se reportant, tout d'abord à la figure 1, le brûleur repéré dans son ensemble 1 comporte essen tiellement une chambre 2 de répartition dans laquelle arrive, par une conduite 3 d'alimentation, le prémélange air/gaz combustible débouchant avantageusement dans la chambre 2 par une ouverture sensiblement radiale 4. La chambre 2 qui a la forme générale d'un caisson cylindrique à section sensiblement circulaire est obturée, sur sa face avant, par une grille métallique de stabilisation de flammes 5. Cette grille qui est donc relativement sensible aux contraintes thermiques (comparée aux plaquettes céramiques) dans certaines conditions de fonctionnement du brûleur peut en particulier être du type décrit à la demande française sus-mentionnée n, 83 09468. De façon plus spécifique, elle comportera des orifices de diamètre et de répartition convenables pour assurer un bon accrochage et une bonne stabilisation des flammes à l'entrée de la chambre de combustion 6, et ce pour les puissances considérées de fonctionnement du brûleur.Referring first to Figure 1, the burner identified as a whole 1 comprises essen tially a
Sur sa face arrière, le caisson formant la chambre de répartition 2 est fermée par une paroi 7. Sur la figure 1 on a repéré par les lettre AV et AR le côté respectivement "avant" et "arrière" du brûleur, en faisant référence à la circulation du mélange combustible dans la brûleur tel que shématisé par les flèches.On its rear face, the box forming the
Tel qu'illustré, l'allumage du brûleur est assuré par une électrode 8 alimentée sous haute tension convenable comme shématisé en 9 et convenablement isolée, l'allumage s'effectuant par étincelles entre la pointe recourbée 10ʹ de l'électrode d'allumage et la paroi voisine de la grille 5 ou du flasque avant 11 métallique sur laquelle est fixée la grille 5 et qui est mise à la masse du caisson formant la chambre de répartition 2.As illustrated, 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 10ʹ of the ignition electrode and the wall next to the
Pour contrôler le bon fonctionnement du brûleur, c'est à dire en particulier les conditions de combustion de la flamme qui se développe dans la chambre de combustion, ainsi que la position de cette flamme, on a prévu une électrode d'ionisation 12 également alimentée sous tension convenable comme schématisé en 10 et convenablement isolée, la detection des conditions de développement de la flamme s'effectuant entre la pointe 13 de l'électrode 12 et la masse voisine de la grille 5.To control the proper functioning of the burner, that is to say in particular the conditions of combustion of the flame which develops in the combustion chamber, as well as the position of this flame, an
La pointe 13 de l'électrode d'ionisation 12 est, telle qu'illustrée, sensiblement droite et dirigée sensiblement parallèlement à la direction d'écoulement du mélange gazeux.The
Les deux électrodes 8 et 12 sont montées, également sensiblement parallèlement à la direction d'écoulement du mélange combustible, de façon à traverser la grille 5 de stabilisation de flammes vers la partie centrale de celle-ci et avec leurs pointes respectives 10 et 13 s'étendant dans la chambre de combustion. Les cables d'alimentation électriques 9 et 10 des électrodes s'étendent, tel qu'illustré, dans la chambre de répartition 2 et traversent, de façon étanche aux pressions de fonctionnement considérées, la paroi de celle-ci respecvement en 14 et 15. L'étanchéité peut notamment être assurée par des presse-étoupes.The two
Vers l'arrière de la chambre de répartition 2, vers le fond d'un embout 22 débouchant dans cette chambre, apparaît un voyant 23 de contrôle visuel de la flamme. On notera que le voyant 15 est disposé de façon tout à fait appropriée et bien protégé des contraintes thermiques.Towards the rear of the
En se référant maintenant à la figure 2, on voit que le brûleur est alimenté en gaz combustible par une conduite 16, le prémélange étant ainsi délivré au conduit 3 dans des conditions sensiblement stoechiométriques. L'air nécessaire à la combustion est délivré par un ventilateur ou compresseur 17 qui alimente le conduit d'air principal 18. Le ventilateur est alimenté en énergie électrique par 24.Referring now to FIG. 2, it can be seen that the burner is supplied with combustible gas via a
Tel qu'illustré sur cette figure 2, on notera que le brûleur décrit ci-dessus permet d'équiper des installations de tubes immergés (ou plus généralement à chambre de combustion immergeable dans le liquide 19 à chauffer) de construction particulièrement compacte.As illustrated in this FIG. 2, it will be noted that the burner described above makes it possible to equip installations with immersed tubes (or more generally with a combustion chamber immersable in the
En 20 à la figure 2 est illustré le tube immergé dans lequel débouchent les produits de combustion s'échappant de la chambre de combustion 6 vers la sortie 21 des fumées.At 20 in FIG. 2 is illustrated the submerged tube into which the combustion products emerging from the combustion chamber 6 open towards the outlet 21 fumes.
Sur les figures schématiques on n'a pas représenté les organes de mise en marche/arrêt du brûleur.In the schematic figures, the burner start / stop members have not been shown.
Cependant, comme on le comprend, l'arrêt du brûleur est commandé par l'électrode d'ionisation 12 dès que celle-ci détecte une absence de flamme .However, as can be understood, the shutdown of the burner is controlled by the
