Description

La présente invention concerne un brûleur notamment destiné à la combustion d'un mélange gazeux.The present invention relates to a burner in particular intended for the combustion of a gaseous mixture.

De façon conventionnelle, un brûleur à gaz à prémélange total comprend schématiquement un mélangeur air/gaz, un ventilateur et une rampe accroche-flamme.Conventionally, a total premix gas burner schematically comprises an air / gas mixer, a fan and a flame-holding ramp.

Lors d'opérations de maintenance des brûleurs et de l'échangeur de chaleur, il est nécessaire d'accéder à la rampe accroche-flamme et au foyer en vue de son nettoyage.During maintenance operations on the burners and the heat exchanger, it is necessary to access the flame holder and the fireplace for cleaning.

Or, dans les brûleurs connus, l'accès à la rampe accroche-flamme nécessite de démonter des éléments en amont de cette dernière, tels que le ventilateur, la vanne de gaz, le mélangeur, etc...Il est alors nécessaire de reformer des connections étanches au gaz et au prémélange entre les éléments lors du remontage après nettoyage.However, in known burners, access to the flame holder ramp requires dismantling elements upstream of the latter, such as the fan, the gas valve, the mixer, etc. It is then necessary to reform gas-tight and premix connections between the elements during reassembly after cleaning.

Ceci est d'autant plus délicat et difficile à mettre en pratique que le montage est parfois hyperstatique et comprend des pièces fixes les unes par rapport aux autres. De plus, les chaudières puissantes utilisent des pièces lourdes et encombrantes à manipuler ce qui rend encore plus complexe le remontage après entretien. Documents US7824178 B1 , FR2896574 A1 , EP1925882 A1 et US6019593 A divulguent des brûleurs selon l'art antérieur.This is all the more delicate and difficult to put into practice as the assembly is sometimes hyperstatic and includes parts that are fixed relative to each other. In addition, powerful boilers use heavy and bulky parts to handle, which makes reassembly after maintenance even more complex. Documents US7824178 B1 , FR2896574 A1 , EP1925882 A1 and US6019593 A disclose burners according to the prior art.

Dans ce contexte technique, un des buts de l'invention réside à pallier l'un au moins de ces inconvénients précités.In this technical context, one of the aims of the invention lies in overcoming at least one of these aforementioned drawbacks.

A cet effet, l'invention propose un brûleur selon la revendication 1. Ce brûleur comprend un ventilateur agencé pour aspirer un mélange gazeux comprenant au moins un gaz et de l'air, une rampe accroche-flamme pourvue d'une pluralité d'ouvertures pour diffuser le mélange gazeux à l'intérieur d'un foyer, un organe de raccordement raccordant fluidiquement le ventilateur à la rampe accroche-flamme, l'organe de raccordement présentant un orifice permettant le dégagement de la rampe accroche-flamme, l'orifice étant obturé par un capot amovible, dans lequel l'organe de raccordement présente une géométrie coudée ayant un angle (a) du coude compris entre 30° et 90°, l'orifice de l'organe de raccordement étant agencé sur ce coude.To this end, the invention provides a burner according to claim 1. This burner comprises a fan arranged to suck a gaseous mixture comprising at least one gas and air, a flame-holding ramp provided with a plurality of openings for diffusing the gaseous mixture inside a hearth, a connection member fluidly connecting the fan to the flame-catching ramp, the connection member having an orifice allowing the release of the flame-holding ramp, the orifice being closed by a removable cover, in which the connection member has a bent geometry having an angle (a) of the elbow between 30 ° and 90 °, the orifice of the connection member being arranged on this elbow.

Ainsi, selon l'invention, il est alors possible de retirer le capot pour avoir accès à la rampe accroche-flamme, dégager la rampe accroche-flamme du brûleur et accéder au foyer de la chaudière pour son nettoyage sans avoir besoin de démonter le ventilateur et autres pièces gênant l'accès à la rampe accroche-flamme. L'entretien est ainsi grandement facilité et il est possible de s'affranchir du contrôle d'étanchéité des connections, notamment entre l'alimentation en gaz et le ventilateur, car ces éléments du brûleur n'ont plus à être démontés. Ceci sécurise l'utilisation du brûleur, et diminue la durée de l'intervention.Thus, according to the invention, it is then possible to remove the cover to gain access to the flame-catching ramp, disengage the flame-catching ramp from the burner and access the boiler hearth for cleaning without the need to dismantle the fan. and other parts obstructing access to the flame trap. Maintenance is thus greatly facilitated and it is possible to dispense with the tightness control of the connections, in particular between the gas supply and the fan, since these elements of the burner no longer have to be disassembled. This secures the use of the burner, and reduces the duration of the intervention.

Il est entendu dans le présent document que le brûleur comprenant un ventilateur agencé pour aspirer un mélange gazeux comprenant au moins un gaz et de l'air est un brûleur à prémélange total.It is understood in this document that the burner comprising a fan arranged to suck up a gas mixture comprising at least one gas and air is a burner with total premix.

Selon l'invention, l'organe de raccordement présente une géométrie coudée, et l'orifice de l'organe de raccordement est agencé sur ce coude. Dans cette conformation, l'axe de sortie i du ventilateur n'est pas superposé à l'axe de la rampe accroche-flamme qui présente alors un accès dégagé et dont le retrait est facilité par ouverture du capot.According to the invention, the connection member has a bent geometry, and the orifice of the connection member is arranged on this elbow. In this configuration, the outlet axis i of the fan is not superimposed on the axis of the flame catching ramp which then has clear access and the removal of which is facilitated by opening the cover.

De préférence, le capot amovible présente une forme générale de calotte sphérique. Cette conformation participe alors à l'homogénéisation du mélange gazeux.Preferably, the removable cover has a general shape of a spherical cap. This conformation then participates in the homogenization of the gas mixture.

Avantageusement, l'organe de raccordement comprend une ouverture de sortie raccordée à la rampe accroche-flamme, l'axe de sortie i du ventilateur et l'axe normal ii à l'ouverture de sortie appartenant respectivement à deux plans parallèles distincts et décalés d'une distance d l'un par rapport à l'autre, de sorte que le mélange gazeux soit introduit tangentiellement dans l'organe de raccordement.Advantageously, the connection member comprises an outlet opening connected to the flame catching ramp, the outlet axis i of the fan and the normal axis ii to the outlet opening belonging respectively to two distinct parallel planes offset by d 'a distance of one relative to the other, so that the gas mixture is introduced tangentially into the connection member.

Cette configuration favorise alors la formation d'un tourbillon dans le mélange gazeux. Il en résulte une meilleure homogénéisation de la répartition du gaz et de l'air du mélange gazeux que celle obtenue dans un mélangeur traditionnel disposé en amont du ventilateur (dans le sens de circulation du mélange gazeux). L'allumage est alors plus fiable, les flammes générées à partir du mélange gazeux sont plus stables et l'émission de polluants tels que le monoxyde de carbone et les oxydes d'azote est limitée.This configuration then promotes the formation of a vortex in the gas mixture. This results in a better homogenization of the distribution of the gas and the air of the gas mixture than that obtained in a traditional mixer placed upstream of the fan (in the direction of circulation of the gas mixture). The ignition is then more reliable, the flames generated from the gas mixture are more stable and the emission of pollutants such as carbon monoxide and nitrogen oxides is limited.

Selon une disposition, l'organe de raccordement comprend un canal sur lequel se raccorde le ventilateur au niveau d'un plan de jonction, le canal débouchant selon l'axe de sortie i du ventilateur, dans le volume intérieur de l'organe de raccordement par une ouverture interne.According to one arrangement, the connection member comprises a channel on which the fan is connected at a junction plane, the channel opening along the outlet axis i of the fan, in the interior volume of the connection member through an internal opening.

De préférence, le canal est prolongé par une paroi ceinturant l'ouverture interne, la paroi se raccordant sur le volume intérieur selon une arrête vive. Ceci favorise encore davantage la formation d'un tourbillon dans le mélange gazeux et participe à améliorer le fonctionnement global du brûleur.Preferably, the channel is extended by a wall surrounding the internal opening, the wall connecting to the interior volume according to a sharp edge. This further promotes the formation of a vortex in the gas mixture and contributes to improving the overall operation of the burner.

Selon l'invention, le plan de jonction et le plan de l'ouverture de sortie de l'organe de raccordement sont orientés de sorte que leur intersection présente un angle α compris entre 30° et 90° et de préférence un angle α d'environ 60°. Cette configuration permet d'obtenir un compromis entre la perte de charge aéraulique générée par la présence de l'organe de raccordement et l'effet de tourbillon homogénéisant le mélange gazeux. Au-delà de cet angle, en effet, l'homogénéisation est améliorée au prix d'une perte de charge aéraulique, en dessous de cet angle, l'inverse se produit.According to the invention, the junction plane and the plane of the outlet opening of the connection member are oriented so that their intersection has an angle α between 30 ° and 90 ° and preferably an angle α of about 60 °. This configuration makes it possible to obtain a compromise between the air pressure drop generated by the presence of the connection member and the vortex effect homogenizing the gas mixture. Beyond this angle, in fact, homogenization is improved at the cost of a loss of air pressure, below this angle, the opposite occurs.

Selon une possibilité, l'organe de raccordement comprend un plan de jonction au niveau duquel est formée la liaison fluidique avec le ventilateur et l'organe de raccordement comprend une ouverture de sortie raccordée à la rampe accroche-flamme, le plan de jonction et le plan de l'ouverture de sortie étant configurés de sorte que leur intersection présente un angle α compris entre 30° et 90° et de préférence un angle d'environ 60°.According to one possibility, the connection member comprises a junction plane at the level of which the fluid connection with the fan is formed and the connection member comprises an outlet opening connected to the flame catching ramp, the junction plane and the plane of the outlet opening being configured so that their intersection has an angle α of between 30 ° and 90 ° and preferably an angle of about 60 °.

Selon une possibilité avantageuse, l'organe de raccordement comprend

  • un siège de clapet anti-retour entourant l'ouverture interne, le siège de clapet anti-retour présentant un angle égal ou supérieur à 90° par rapport à l'horizontale, et
  • un clapet anti-retour mobile entre une première position de repos contre le siège et obturant l'ouverture interne et une seconde position de libération de l'ouverture interne, de sorte à limiter fortement le retour des fumées générées par la combustion du mélange gazeux dans le foyer lorsque le brûleur est à l'arrêt.
According to an advantageous possibility, the connecting member comprises
  • a non-return valve seat surrounding the internal opening, the non-return valve seat having an angle equal to or greater than 90 ° relative to the horizontal, and
  • a movable non-return valve between a first rest position against the seat and closing the internal opening and a second position for releasing the internal opening, so as to greatly limit the return of the fumes generated by the combustion of the gas mixture in the fireplace when the burner is off.

L'angle formé entre le siège et le plan de l'ouverture de sortie ou le plan horizontal permet avantageusement au clapet anti-retour de reposer sur le siège par simple gravité. Cet angle, différent de l'angle α entre le plan de jonction et le plan de l'ouverture de sortie, peut être obtenu facilement par la présence du canal donnant de l'espace permettant de prévoir un siège présentant une inclinaison différente de celle du plan de jonction.The angle formed between the seat and the plane of the outlet opening or the horizontal plane advantageously allows the non-return valve to rest on the seat by simple gravity. This angle, different from the angle α between the junction plane and the plane of the outlet opening, can be easily obtained by the presence of the channel giving space allowing to provide a seat having a different inclination than that of the junction plane.

Avantageusement le clapet anti-retour est amovible.Advantageously, the non-return valve is removable.

Avantageusement, l'organe de raccordement comprend des moyens d'étanchéité permettant d'assurer l'étanchéité au moins entre l'organe de raccordement et le foyer, et entre l'organe de raccordement et le ventilateur. Ainsi, l'entretien du brûleur peut être réalisé sans démonter les connections étanches entre l'organe de raccordement et les autres éléments de la chaudière, par simple retrait du capot amovible. L'étanchéité de ces connections n'est donc pas à contrôler à la fin de l'intervention, contrairement au dispositif de l'art antérieur.Advantageously, the connection member comprises sealing means making it possible to seal at least between the connection member and the hearth, and between the connection member and the fan. Thus, maintenance of the burner can be carried out without dismantling the sealed connections between the connection member and the other elements of the boiler, by simply removing the removable cover. The tightness of these connections is therefore not to be checked at the end of the intervention, unlike the device of the prior art.

Selon une disposition, l'organe de raccordement comprend au moins un des dispositifs choisi parmi un support pour électrodes d'allumage, un viseur de flamme, un support pour électrode d'ionisation, et un organe de mesure de la pression dans le foyer. La surface extérieure de l'organe de raccordement est alors utilisée pour y disposer des fonctions secondaires du brûleur, qui sont alors facilement accessibles. De plus, l'intégration de ces fonctions secondaires directement sur une pièce de fonderie est plus économique que de prévoir ces fonctions sur de nombreuses autres pièces annexes.According to one arrangement, the connection member comprises at least one of the devices chosen from a support for ignition electrodes, a flame finder, a support for ionization electrode, and a member for measuring the pressure in the furnace. The outer surface of the connection member is then used to provide secondary functions of the burner, which are then easily accessible. In addition, the integration of these secondary functions directly on a foundry part is more economical than providing these functions on many other ancillary parts.

Plus précisément, l'angle α du coude 5 est compris entre 30° et 90° et de préférence l'angle α est d'environ 60°.The connecting member 4 has a bend 5 in which is formed an orifice closed by a removable cover 6. More precisely, the angle α of the bend 5 is between 30 ° and 90 ° and preferably the angle α is d 'about 60 °.

Cette disposition permet de retirer la rampe accroche-flamme 2 à travers l'orifice après retrait du capot amovible 6 (figure 3). Il est ainsi possible d'effectuer le nettoyage de la rampe accroche-flamme 2 et d'accéder au foyer pour son entretien sans avoir besoin de démonter le ventilateur 1, le mélangeur et la vanne de gaz alimentant le mélangeur en amont.This arrangement makes it possible to remove the flame catching ramp 2 through the orifice after removal of the removable cover 6 ( figure 3 ). It is thus possible to carry out the cleaning of the flame catching rail 2 and to access the fireplace for its maintenance without the need to dismantle the fan 1, the mixer and the gas valve supplying the mixer upstream.

L'organe de raccordement 4 illustré à la figure 2 comprend une ouverture de sortie 8, connectée à la rampe accroche-flamme 2 pour le transfert du mélange de gaz et d'air vers le foyer. L'organe de raccordement 4 comprend également un canal 10 connecté au ventilateur 1 au niveau d'un plan de jonction 18 comme visible sur la figure 6. Le canal 10 est prolongé par une paroi 17 ceinturant une ouverture interne 7, cette dernière donnant accès au volume intérieur 22 de l'organe de raccordement 4.The connecting member 4 illustrated in the figure 2 includes an outlet opening 8, connected to the flame catching rail 2 for the transfer of the gas and air mixture to the hearth. The connection member 4 also comprises a channel 10 connected to the fan 1 at a junction plane 18 as visible on the figure 6 . The channel 10 is extended by a wall 17 surrounding an internal opening 7, the latter giving access to the internal volume 22 of the connection member 4.

Comme illustré à la figure 2, un joint d'étanchéité 9 est inséré entre l'organe de raccordement 4 et le capot amovible 6 pour garantir l'étanchéité de l'organe de raccordement 4 au mélange gazeux. L'organe de raccordement 4 comprend également des moyens d'étanchéité, telles que des gorges de joint 21, par exemple pour joint torique, à l'interface entre l'organe de raccordement 4 et le foyer ainsi qu'à l'interface entre l'organe de raccordement 4 et le ventilateur 1 (figures 2 et 3).As illustrated in figure 2 , a seal 9 is inserted between the connection member 4 and the removable cover 6 to guarantee the tightness of the connection member 4 to the gas mixture. The connection member 4 also comprises sealing means, such as seal grooves 21, for example for O-ring, at the interface between the connection member 4 and the hearth as well as at the interface between the connection member 4 and the fan 1 ( figures 2 and 3 ).

La figure 4 illustre le volume intérieur 22 de l'organe de raccordement 4 dans lequel l'axe du canal 10 n'est pas dans le même plan que l'axe normal ii à l'ouverture de sortie 8. Comme cela apparait sur cette figure, l'axe du canal 10 et l'axe normal ii à l'ouverture de sortie 8 appartiennent à des plans parallèles distincts décalés d'une distante d. Cette disposition permet de créer un tourbillon dans l'écoulement du mélange gazeux en l'introduisant de manière tangentielle. Cela contribue à améliorer son homogénéité. De plus, la paroi 17 se raccorde au volume intérieur 22 selon une arête vive 23 qui contribue à accentuer le mouvement de tourbillon.The figure 4 illustrates the internal volume 22 of the connection member 4 in which the axis of the channel 10 is not in the same plane as the normal axis ii at the outlet opening 8. As appears in this figure, l the axis of the channel 10 and the normal axis ii at the outlet opening 8 belong to separate parallel planes offset by a distance d. This arrangement makes it possible to create a vortex in the flow of the gas mixture by introducing it tangentially. This contributes to improving its homogeneity. In addition, the wall 17 is connected to the interior volume 22 according to a sharp edge 23 which contributes to accentuate the movement of the vortex.

L'organe de raccordement comprend un siège 19 pour un clapet anti-retour 11, le siège 19 étant orienté, grâce à la présence du canal 10, de sorte à présenter un angle égal ou supérieur à 90° par rapport à l'horizontale comme illustré à la figure 6. Le clapet anti-retour 11 peut donc reposer par simple gravité contre le siège 19, ce qui n'aurait pas été possible si le clapet 11 était accueilli dans le bord du plan de jonction 18. Ainsi le clapet 11 est conçu pour être mobile entre deux positions, une première position de repos où le clapet repose contre le siège 19 de sorte à obturer l'ouverture interne 7 et une seconde position dans laquelle le clapet 11 libère l'ouverture interne 7 telle qu'illustré sur la figure 6. Ainsi, lorsque le brûleur 100 se met à l'arrêt la présence de ce clapet anti-retour 11 permet d'éviter que les fumées provenant de la combustion du mélange gazeux ne remontent trop abondamment vers le ventilateur 1.The connection member comprises a seat 19 for a non-return valve 11, the seat 19 being oriented, by virtue of the presence of the channel 10, so as to present an angle equal to or greater than 90 ° relative to the horizontal as illustrated in figure 6 . The non-return valve 11 can therefore rest by simple gravity against the seat 19, which would not have been possible if the valve 11 was received in the edge of the junction plane 18. Thus the valve 11 is designed to be movable between two positions, a first rest position where the valve rests against the seat 19 so as to close off the internal opening 7 and a second position in which the valve 11 releases the internal opening 7 as illustrated in the figure 6 . Thus, when the burner 100 stops, the presence of this non-return valve 11 makes it possible to prevent the fumes from the combustion of the gaseous mixture from rising too abundantly towards the fan 1.

La surface extérieure disponible de l'organe de raccordement 4 peut être utilisée pour agencer des dispositifs secondaires au fonctionnement du brûleur 100, tel qu'un support pour électrode d'allumage 12, un viseur de flamme 13, un support pour électrode d'ionisation 14 et un organe de mesure de la pression 15 du foyer, comme illustré sur la figure 5. De plus, un transformateur d'allumage 16 est disposé sur le capot amovible 6.The available external surface of the connection member 4 can be used to arrange devices secondary to the operation of the burner 100, such as a support for ignition electrode 12, a flame finder 13, a support for ionization electrode 14 and a member for measuring the pressure 15 of the hearth, as illustrated in the figure 5 . In addition, an ignition transformer 16 is arranged on the removable cover 6.

Au cours du fonctionnement du brûleur 100, un ratio déterminé de gaz et d'air est tout d'abord reçu dans un mélangeur, par exemple de type venturi, pour former le mélange gazeux de combustion. Ce dernier est aspiré par le ventilateur 1 qui le propulse vers l'organe de raccordement 4. Le plan de jonction 18 et le plan de l'ouverture de sortie 8 pour le mélange gazeux sont orientés selon un angle d'environ 60°, et les ouvertures 7,8 étant également décalées d'une distance d, une trajectoire en tourbillon du mélange gazeux est générée. Ainsi, le mélange gazeux est très bien homogénéisé à l'entrée de la rampe accroche-flamme 2. Son allumage est alors plus fiable et les flammes générées sont plus stables, ce qui contribue à un bon fonctionnement du brûleur 100. De plus, cette homogénéité du mélange gazeux permet de diminuer l'émission de fumées polluantes dans le foyer.During the operation of the burner 100, a determined ratio of gas and air is firstly received in a mixer, for example of the venturi type, to form the gaseous combustion mixture. The latter is sucked in by the fan 1 which propels it towards the connection member 4. The junction plane 18 and the plane of the outlet opening 8 for the gas mixture are oriented at an angle of approximately 60 °, and the openings 7,8 also being offset by a distance d, a vortex path of the gas mixture is generated. Thus, the gaseous mixture is very well homogenized at the entrance to the flame catching rail 2. Its ignition is then more reliable and the flames generated are more stable, which contributes to the proper functioning of the burner 100. In addition, this homogeneity of the gas mixture reduces the emission of polluting fumes in the home.

La forme générale de calotte sphérique du capot amovible 6, participe à l'homogénéisation du mélange gazeux tout en minimisant la perte de charge.The general shape of the spherical cap of the removable cover 6 participates in the homogenization of the gas mixture while minimizing the pressure drop.

Ainsi, la présente invention apporte une amélioration déterminante à l'état de la technique antérieure en proposant un organe de raccordement 4 doté d'un capot amovible 6, disposé entre le ventilateur 1 et la rampe accroche-flamme 2 du brûleur 100. Ceci permet d'accéder plus facilement à la rampe accroche-flamme 2 et au foyer pour leur entretien. Du fait qu'il n'est plus nécessaire de démonter les éléments en amont de la rampe accroche-flamme 2 et leurs connections étanches, l'entretien est plus rapide et sécurise le fonctionnement du brûleur 100. Ce dernier est par ailleurs amélioré par l'obtention d'un mélange gazeux de combustion plus homogène en sortie de l'organe de raccordement 4.Thus, the present invention provides a decisive improvement in the state of the prior art by proposing a connecting member 4 provided with a removable cover 6, arranged between the fan 1 and the flame-catching ramp 2 of the burner 100. This allows easier access to the flame-holding ramp 2 and to the hearth for their maintenance. Due to the fact that it is no longer necessary to dismantle the elements upstream of the flame-arresting ramp 2 and their sealed connections, maintenance is faster and secures the operation of the burner 100. The latter is also improved by the obtaining a more homogeneous combustion gas mixture at the outlet of the connection member 4.
