- the present invention relates to a heating device with gas burners.
- Gas burners are widely used today, especially for air heating, especially in livestock buildings. Disadvantage major of these burners lies in their reduced power range. Indeed, their operation, based on the ignition of an air / gas mixture, requires a compliance with the proportions of the components in the mixture. It is therefore impossible to vary significantly the amount of gas in the mixing without risking extinguishing the flame. Therefore, the trend today is to use powerful burners which are frequently switched between on and off positions for temperature regulation. It results from user comfort problems due to the inertia of its burners.
- a heating device To be able to cover a large power range without having to have powerful burners, a heating device has been devised several gas burners of the same power.
- the burners are divided into a burner, called a master, equipped with a device of ignition of air / gas mixture and in burners, called slaves, free of such device.
- the transition from one power stage to another is carried out by ignition of the burner immediately adjacent to the burner previously lit. This results in the obligation to carry out the lighting of said burners in an order predetermined according to the relative positioning of the burners on the pipe common gas supply.
- this solution may cover a large power range, the number of power stages is reduced and the stages between power stages are of constant value. This is due to fact that the gas burners used are all of the same power and that only ignition of a burner, immediately adjacent to a previously burner on, can be considered. Burner combinations are therefore limited.
- An object of the present invention is to overcome the aforementioned drawbacks by offering a heating device whose design allows variation power over a wide range, the value of the steps between stages of power can be freely chosen by the user so as to offer a great number of possibilities to the latter.
- Another object of the present invention is to provide a heating device whose number of burners, although reduced, allows a variation of power within a wide range while ensuring operation optimal and perfectly safe flame control device.
- Another object of the present invention is to provide a heating device simple in design and the number of parts can be reduced without affecting the safety of the whole.
- Another object of the present invention is to provide a heating device having a large number of power stages for a given number of burners, each power stage corresponding to a combination predetermined burners arranged in any manner in the device.
- the invention relates to a heating device of the type constituted at least three burners, respectively connected to a common line gas supply, itself connected to a gas supply source, each burner can be independently supplied with gas by via a lockable link with controlled opening / closing between the gas supply source and the burner, the burners being at least two types differing in their heating power, these burners being associated according to different selectable combinations corresponding each with a power stage, the control means opening / closing of the link of each controlling burner, when transition from a power stage N to a selected power stage P, the opening of the link of the burner (s) to light on the power stage P selected and at least the opening of the connections of all the burners separating a burner lit on the power stage N from a burner to be lit at the power stage P to allow automatic ignition of the flame of each burner by contact with the air / gas mixture expelled from said burner with the flame of an adjacent burner until the burner ignites at stage P selected then selective closing of burner connections not included in the combination corresponding to the power stage P selected,
- the device flame control can be common to all burners and activated by any of the burners due to the fact that when passing through a stage of power to another, all burners work.
- a release of sufficient heat to guarantee continued operation of the flame control in the case of a device operating by infrared either the temperature rise of the probe in the case of a control device of the flame operating by ionization.
- This ignition of all burners during the transitional period thus makes it possible to pass from a stage of power to another without having any common burner lit between the two stages thus increasing the number of combinations and as a result of power possible.
- the heating device is consisting of burners 1 connected to a rigid gas supply pipe 2, generally metallic, itself connected to a power source 3 gas which can be any.
- the whole forms what one could call a gas burner burner 1.
- the burners 1 act conventionally by combustion of an air / gas mixture.
- These burners 1 can be of the type atmospheric or dynamic. In such a device, these burners 1 will be at fewer than three.
- Each burner 1 comprises, per se known, a duct comprising at least one combustion air inlet primary and containing at least the gas injector and a mixing chamber air / gas, this conduit opening into a combustion chamber of the mixture air / gas.
- the duct contains, between the injector and the air / gas mixing chamber, a venturi element. The detail of such burners will not be provided because many examples of embodiment of burners can be found in the literature.
- the heating device object of the invention, there is preferably a distinction two types of burners, namely a so-called master burner, fitted with a device 4 of the air / gas mixture ignition and of the burners 1, called slaves, which differentiate from the master burner by the fact that they are device-free ignition of the air / gas mixture.
- the device 4 for igniting the mixture air / gas will not be described in detail since it can be constituted in itself known from an electrical device of resistance, sparks or other type, from a night light or the like.
- Each burner comprises at least one device 11 for flame control. This flame control device 11 is thus common to all burners.
- This flame control device 11 can be consisting of an optical device, an ionization device, a infrared or any other means which ensures, when the flame, closing the supply to the common supply line gas from the gas supply source by means of a valve appropriate closure.
- this device 11 is a device to ionization consisting of a probe and a metal rod coming to cap the middle burner and extending along each of the burners adjoining this median burner. The cooperation of this flame control device 11 with the burner control means will be described below.
- Each burner 1, master or slave, is connected to the power source 3 in gas via the common gas supply line 2 and a tap on said pipe 2.
- Each connecting portion 5, produced between the source 3 of gas supply and a burner 1 is provided with a member 6 such that a solenoid valve ensuring the opening or closing of the link 5 between the burner 1 and source 3 of gas supply.
- This opening / closing of the link 5 is controlled by means of a suitable control device in depending on the power stage selected.
- the heater comprises a plurality of burners 1. Among these burners, there are at least two types of burners 1 differentiated by their heating power. Of preferably, the lower power burner 1 is placed between two other burners 1.
- burners are associated in operation according to combinations any predetermined randomly selectable for example by means of a programmer, each combination corresponding to a power stage. So it can be imagined a device heater with four burners with heating output differentiated.
- the first stage corresponds to the operation of the master burner of lower power
- the second power stage to the combination of lower power burner with power burner immediately above ...
- the top floor corresponding to a combination where the whole burners are working, i.e. are lit.
- the heating device therefore further comprises means for selecting a power stage corresponding to a predetermined combination of burner (s) in operation from a plurality of stages.
- selection means can be constituted by a programmer.
- it can be chosen, for a heating device comprising four burners, respectively called B1, B2, B3, B4, to define a first power stage corresponding to a supply of air / gas mixture of B1, the connections of the other burners remaining closed.
- a second power stage can be defined in which only the burner B3 of a power different from the burner B1 is lit.
- Other combinations can thus be defined, the total number of combinations being at most equal to 2 x , x corresponding to the number of burners in the installation.
- the means 7 for controlling the opening / closing of the connection of each burner control when passing from a power stage N to any new power stage P selected at any point, the opening of all the connections 5 of the burners 1 to allow, by automatic ignition of the flame of a burner by contact of the air / gas mixture expelled from the burner with the flame of an adjacent burner, the ignition of all the burners then the selective closing of the burner links 5 not included in the combination corresponding to the new selected power stage.
- This solution makes it possible to dispense with means of memorizing the combinations of burners coupled to means 7 for controlling opening / closing links. Thus, between each passage of a stage of power to another, all the burners are put into operation by automatic opening of links 5. On the other hand, this solution allows guarantee activation of the flame control device 11 by one any of the burners, regardless of the power level selected.
- the controlled opening / closing shutter member 6 of the link 5 between a burner 1 and the gas supply source 3 is a solenoid valve.
- the opening / closing of the solenoid valves can be controlled by means of electrical signals emitted from information emanating from a central control, such as a microprocessor. This central manages information relating to the power stage selected to determine the connections in front be open or closed respectively.
- the interval between two adjacent burner heads is chosen so as to allow self-ignition two adjacent burners in less than a tenth of a second.

Description
La présente invention concerne un dispositif de chauffage à brûleurs à gaz.The present invention relates to a heating device with gas burners.
Elle concerne plus particulièrement un dispositif de chauffage du type constitué d'au moins trois brûleurs respectivement raccordés à une conduite commune d'alimentation en gaz, chaque brûleur pouvant être indépendamment alimenté en gaz par l'intermédiaire d'une liaison obturable à ouverture/fermeture commandée entre la source d'alimentation en gaz et le brûleur, les brûleurs étant d'au moins deux types se différenciant par leur puissance de chauffe, ces brûleurs étant associés suivant différentes combinaisons sélectionnables correspondant chacune à un étage de puissance, les moyens de commande d'ouverture/fermeture de la liaison de chaque brûleur commandant, lors du passage d'un étage de puissance N à un étage de puissance P sélectionné, l'ouverture de la liaison du ou des brûleur(s) à allumer à l'étage de puissance P sélectionné et au moins l'ouverture des liaisons de l'ensemble des brûleurs séparant un brûleur allumé à l'étage de puissance N d'un brûleur à allumer à l'étage de puissance P pour permettre une inflammation automatique de la flamme de chaque brûleur par contact du mélange air/gaz expulsé dudit brûleur avec la flamme d'un brûleur adjacent jusqu'à allumage du brûleur à allumer à l'étage P sélectionné puis la fermeture sélective des liaisons des brûleurs non inclus dans la combinaison correspondant à l'étage de puissance P sélectionné.It relates more particularly to a heating device of the type constituted at least three burners respectively connected to a common line gas supply, each burner being able to be independently supplied in gas via a closable opening / closing link controlled between the gas supply source and the burner, the burners being of at least two types differentiating by their heating power, these burners being combined in different selectable combinations each corresponding to a power stage, the control means opening / closing of the link of each controlling burner, when transition from a power stage N to a selected power stage P, the opening of the link of the burner (s) to light on the power stage P selected and at least the opening of the connections of all the burners separating a burner lit on the power stage N from a burner to be lit at the power stage P to allow automatic ignition of the flame of each burner by contact with the air / gas mixture expelled from said burner with the flame of an adjacent burner until the burner ignites at stage P selected then selective closing of burner connections not included in the combination corresponding to the power stage P selected.
Les brûleurs à gaz sont aujourd'hui largement utilisés, notamment pour le réchauffage de l'air, en particulier dans les bâtiments d'élevage. L'inconvénient majeur de ces brûleurs réside dans leur plage de puissance réduite. En effet, leur fonctionnement, basé sur l'inflammation d'un mélange air/gaz, nécessite un respect des proportions des composants dans le mélange. Il est donc impossible de faire varier, de manière importante, la quantité de gaz dans le mélange sans risquer d'éteindre la flamme. De ce fait, la tendance aujourd'hui est d'utiliser des brûleurs puissants qui sont fréquemment commutés entre les positions marche et arrêt pour obtenir une régulation de la température. Il en résulte des problèmes de confort de l'utilisateur en raison de l'inertie de ses brûleurs.Gas burners are widely used today, especially for air heating, especially in livestock buildings. Disadvantage major of these burners lies in their reduced power range. Indeed, their operation, based on the ignition of an air / gas mixture, requires a compliance with the proportions of the components in the mixture. It is therefore impossible to vary significantly the amount of gas in the mixing without risking extinguishing the flame. Therefore, the trend today is to use powerful burners which are frequently switched between on and off positions for temperature regulation. It results from user comfort problems due to the inertia of its burners.
Pour pouvoir couvrir une plage de puissance importante sans avoir à disposer de brûleurs puissants, il a été imaginé un dispositif de chauffage comportant plusieurs brûleurs à gaz de puissance identique. Dans une telle installation, les brûleurs sont répartis en un brûleur, dit maítre, équipé d'un dispositif d'inflammation de mélange air/gaz et en brûleurs, dits esclaves, exempts d'un tel dispositif. Le passage d'un étage de puissance à un autre s'effectue par allumage du brûleur immédiatement adjacent au brûleur préalablement allumé. Il en résulte l'obligation d'effectuer l'allumage desdits brûleurs suivant un ordre prédéterminé fonction du positionnement relatif des brûleurs sur la conduite commune d'alimentation en gaz. Bien que cette solution puisse couvrir une plage de puissance importante, le nombre d'étages de puissance est réduit et les paliers entre étages de puissance sont de valeur constante. Ceci est dû au fait que les brûleurs à gaz utilisés sont tous de même puissance et que seul l'allumage d'un brûleur, immédiatement adjacent à un brûleur préalablement allumé, peut être envisagé. Les combinaisons de brûleurs sont donc limitées.To be able to cover a large power range without having to have powerful burners, a heating device has been devised several gas burners of the same power. In such an installation, the burners are divided into a burner, called a master, equipped with a device of ignition of air / gas mixture and in burners, called slaves, free of such device. The transition from one power stage to another is carried out by ignition of the burner immediately adjacent to the burner previously lit. This results in the obligation to carry out the lighting of said burners in an order predetermined according to the relative positioning of the burners on the pipe common gas supply. Although this solution may cover a large power range, the number of power stages is reduced and the stages between power stages are of constant value. This is due to fact that the gas burners used are all of the same power and that only ignition of a burner, immediately adjacent to a previously burner on, can be considered. Burner combinations are therefore limited.
Il en est de même du brûleur à becs multiples décrit dans le brevet FR-A-2.800.847 où le réglage de la puissance du brûleur s'opère par réglage du nombre de becs alimentés. La configuration de ce brûleur à becs multiples oblige à sélectionner toujours au moins un groupe de becs parmi un ensemble formé de deux groupes de becs quel que soit le niveau de puissance selon lequel le brûleur fonctionne. Cette obligation est due au fait que l'on détecte la présence de la flamme dans une région chevauchant les deux groupes de bacs mentionnés ci-dessus. La sélection obligatoire d'au moins l'un des groupes de becs empêche à nouveau d'obtenir avec peu de becs une variation dans une large plage de la puissance. Cette sélection parmi deux groupes est rendue obligatoire pour des raisons de sécurité du fait du mode de fonctionnement du brûleur pour le passage d'un étage de puissance à un autre. It is the same for the burner with multiple burners described in patent FR-A-2,800,847 where the burner power is adjusted by adjusting the number of spouts fed. The configuration of this burner with multiple burners always select at least one group of mouthpieces from a set formed of two groups of nozzles whatever the power level according to which the burner is operating. This obligation is due to the fact that the presence of the flame in a region overlapping the two groups of tanks mentioned above. Mandatory selection of at least one of the groups of spouts again prevents obtaining with a few spouts a variation in a wide power range. This selection from two groups is made mandatory for security reasons due to the operating mode of the burner for switching from one power stage to another.
Un but de la présente invention est de pallier les inconvénients précités en proposant un dispositif de chauffage dont la conception permet une variation de la puissance dans une large plage, la valeur des paliers entre étages de puissance pouvant être choisie librement par l'utilisateur de manière à offrir un grand nombre de possibilités à ce dernier.An object of the present invention is to overcome the aforementioned drawbacks by offering a heating device whose design allows variation power over a wide range, the value of the steps between stages of power can be freely chosen by the user so as to offer a great number of possibilities to the latter.
Un autre but de la présente invention est de proposer un dispositif de chauffage dont le nombre de brûleurs, bien que réduit, permet d'obtenir une variation de puissance à l'intérieur d'une large plage tout en garantissant un fonctionnement optimal et parfaitement sûr du dispositif de contrôle de la flamme.Another object of the present invention is to provide a heating device whose number of burners, although reduced, allows a variation of power within a wide range while ensuring operation optimal and perfectly safe flame control device.
Un autre but de la présente invention est de proposer un dispositif de chauffage de conception simple et dont le nombre de pièces peut être réduit sans nuire à la sûreté de l'ensemble.Another object of the present invention is to provide a heating device simple in design and the number of parts can be reduced without affecting the safety of the whole.
Un autre but de la présente invention est de proposer un dispositif de chauffage disposant d'un grand nombre d'étages de puissance pour un nombre donné de brûleurs, chaque étage de puissance correspondant à une combinaison prédéterminée des brûleurs disposés de manière quelconque dans le dispositif.Another object of the present invention is to provide a heating device having a large number of power stages for a given number of burners, each power stage corresponding to a combination predetermined burners arranged in any manner in the device.
A cet effet, l'invention a pour objet un dispositif de chauffage du type constitué d'au moins trois brûleurs, respectivement raccordés à une conduite commune d'alimentation en gaz, elle-même reliée à une source d'alimentation en gaz, chaque brûleur pouvant être indépendamment alimenté en gaz par l'intermédiaire d'une liaison obturable à ouverture/fermeture commandée entre la source d'alimentation en gaz et le brûleur, les brûleurs étant d'au moins deux types se différenciant par leur puissance de chauffe, ces brûleurs étant associés suivant différentes combinaisons sélectionnables correspondant chacune à un étage de puissance, les moyens de commande d'ouverture/fermeture de la liaison de chaque brûleur commandant, lors du passage d'un étage de puissance N à un étage de puissance P sélectionné, l'ouverture de la liaison du ou des brûleur(s) à allumer à l'étage de puissance P sélectionné et au moins l'ouverture des liaisons de l'ensemble des brûleurs séparant un brûleur allumé à l'étage de puissance N d'un brûleur à allumer à l'étage de puissance P pour permettre une inflammation automatique de la flamme de chaque brûleur par contact du mélange air/gaz expulsé dudit brûleur avec la flamme d'un brûleur adjacent jusqu'à allumage du brûleur à allumer à l'étage P sélectionné puis la fermeture sélective des liaisons des brûleurs non inclus dans la combinaison correspondant à l'étage de puissance P sélectionné, caractérisé en ce que le dispositif comporte au moins un dispositif de contrôle de la flamme commun à tous les brûleurs et en ce que les moyens de commande d'ouverture/fermeture de la liaison de chaque brûleur commandent, lors du passage d'un étage de puissance à un nouvel étage de puissance sélectionné, l'ouverture des liaisons de tous les brûleurs du dispositif pour permettre, par inflammation automatique de la flamme d'un brûleur par contact du mélange air/gaz expulsé du brûleur avec la flamme d'un brûleur adjacent, l'allumage de tous les brûleurs puis la fermeture sélective des liaisons des brûleurs non inclus dans la combinaison correspondant au nouvel étage de puissance sélectionné, cette commande permettant l'activation du dispositif de contrôie de la flamme par l'un quelconque des brûleurs.To this end, the invention relates to a heating device of the type constituted at least three burners, respectively connected to a common line gas supply, itself connected to a gas supply source, each burner can be independently supplied with gas by via a lockable link with controlled opening / closing between the gas supply source and the burner, the burners being at least two types differing in their heating power, these burners being associated according to different selectable combinations corresponding each with a power stage, the control means opening / closing of the link of each controlling burner, when transition from a power stage N to a selected power stage P, the opening of the link of the burner (s) to light on the power stage P selected and at least the opening of the connections of all the burners separating a burner lit on the power stage N from a burner to be lit at the power stage P to allow automatic ignition of the flame of each burner by contact with the air / gas mixture expelled from said burner with the flame of an adjacent burner until the burner ignites at stage P selected then selective closing of burner connections not included in the combination corresponding to the power stage P selected, characterized in that the device comprises at least one device flame control common to all burners and in that the means for opening / closing the connection of each burner when switching from a power stage to a new stage, power selected, the opening of the connections of all the burners of the device to allow, by automatic ignition of the flame of a burner by contact of the air / gas mixture expelled from the burner with the flame of a burner adjacent, ignition of all burners then selective closing of links burners not included in the combination corresponding to the new stage of power selected, this command enabling the activation of the flame control by any of the burners.
Le fait de disposer d'au moins trois brûleurs présentant des puissances de chauffe différenciées permet de disposer au maximum de 2x étages de puissance, x correspondant au nombre de brûleurs du dispositif de chauffage. Ce grand nombre de possibilités de combinaisons des brûleurs pour obtenir des puissances de chauffe variables rend un tel dispositif de chauffage approprié pour de nombreuses applications. La progressivité de la puissance peut s'effectuer de manière régulière ou non au gré de l'utilisateur, en fonction de l'étage de puissance sélectionné, cette sélection étant opérée librement par l'utilisateur.Having at least three burners having differentiated heating powers makes it possible to have at most 2 x power stages, x corresponding to the number of burners of the heating device. This large number of possibilities of combinations of the burners to obtain variable heating powers makes such a heating device suitable for many applications. The progressiveness of the power can be carried out regularly or not at the discretion of the user, depending on the power stage selected, this selection being carried out freely by the user.
Par ailleurs, du fait du mode de fonctionnement des moyens de commande d'ouverture/fermeture de la liaison de chaque brûleur, le passage d'un étage de puissance à un autre étage de puissance peut s'effectuer sans avoir à multiplier le nombre de dispositifs de contrôle de la flamme sur les brûleurs. Il en résulte ainsi une installation de conception extrêmement simple. En effet,le dispositif de contrôle de la flamme peut être commun à tous les brûleurs et activé par l'un quelconque des brûleurs grâce au fait que, lors du passage d'un étage de puissance à un autre, tous les brûleurs fonctionnent. Il en résulte, pendant la période transitoire entre deux étages de puissance, soit un dégagement de chaleur suffisante pour garantir la poursuite du fonctionnement du dispositif de contrôle de la flamme dans le cas d'un dispositif fonctionnant par infrarouges, soit la mise en température de la sonde dans le cas d'un dispositif de contrôle de la flamme fonctionnant par ionisation. Cet allumage de tous les brûleurs pendant la période transitoire permet ainsi de passer d'un étage de puissance à un autre sans avoir aucun brûleur commun allumé entre les deux étages augmentant ainsi le nombre de combinaisons et par suite d'étapes de puissance possible.Furthermore, due to the operating mode of the control means opening / closing of the connection of each burner, the passage of a stage of power to another power stage can be done without having to multiply the number of flame control devices on the burners. The result thus an extremely simple design installation. Indeed, the device flame control can be common to all burners and activated by any of the burners due to the fact that when passing through a stage of power to another, all burners work. As a result, during the transitional period between two power stages, i.e. a release of sufficient heat to guarantee continued operation of the flame control in the case of a device operating by infrared, either the temperature rise of the probe in the case of a control device of the flame operating by ionization. This ignition of all burners during the transitional period thus makes it possible to pass from a stage of power to another without having any common burner lit between the two stages thus increasing the number of combinations and as a result of power possible.
Ainsi, parallèlement, une telle conception permet d'obtenir une grande modularité du dispositif de chauffage qui couvre alors une plage de puissance importante.Thus, in parallel, such a design makes it possible to obtain a large modularity of the heating device which then covers a power range important.
L'invention sera bien comprise à la lecture de la description suivante d'exemples de réalisation, en référence à la figure unique qui représente une vue schématique d'un dispositif de chauffage conforme à l'invention, ce dispositif étant incorporé dans un générateur d'air à température contrôlée.The invention will be clearly understood on reading the following description of exemplary embodiments, with reference to the single figure which represents a schematic view of a heating device according to the invention, this device being incorporated in a temperature controlled air generator.
Comme mentionné ci-dessus, le dispositif de chauffage, objet de l'invention, est constitué de brûleurs 1 raccordés à une conduite 2 rigide d'alimentation en gaz, généralement métallique, elle-même reliée à une source 3 d'alimentation en gaz qui peut être quelconque. L'ensemble forme ce que l'on pourrait appeler une rampe à brûleurs 1 à gaz. Les brûleurs 1 agissent classiquement par combustion d'un mélange air/gaz. Ces brûleurs 1 peuvent être de type atmosphérique ou dynamique. Dans un tel dispositif, ces brûleurs 1 seront au moins au nombre de trois. Chaque brûleur 1 comprend, de manière en soi connue, un conduit comportant au moins une entrée d'air de combustion primaire et renfermant au moins l'injecteur de gaz et une chambre de mélange air/gaz, ce conduit débouchant dans une chambre de combustion du mélange air/gaz. Dans le cas de brûleurs atmosphériques, le conduit renferme, entre l'injecteur et la chambre de mélange air/gaz, un élément venturi. Le détail de tels brûleurs ne sera pas fourni car de nombreux exemples de réalisation de brûleurs peuvent être trouvés dans la littérature.As mentioned above, the heating device, object of the invention, is consisting of burners 1 connected to a rigid gas supply pipe 2, generally metallic, itself connected to a power source 3 gas which can be any. The whole forms what one could call a gas burner burner 1. The burners 1 act conventionally by combustion of an air / gas mixture. These burners 1 can be of the type atmospheric or dynamic. In such a device, these burners 1 will be at fewer than three. Each burner 1 comprises, per se known, a duct comprising at least one combustion air inlet primary and containing at least the gas injector and a mixing chamber air / gas, this conduit opening into a combustion chamber of the mixture air / gas. In the case of atmospheric burners, the duct contains, between the injector and the air / gas mixing chamber, a venturi element. The detail of such burners will not be provided because many examples of embodiment of burners can be found in the literature.
Dans le dispositif de chauffage, objet de l'invention, on distingue de préférence deux types de brûleurs, à savoir un brûleur, dit maítre, équipé d'un dispositif 4 d'inflammation de mélange air/gaz et des brûleurs 1, dits esclaves, qui se différencient du brûleur maítre par le fait qu'ils sont exempts de dispositif d'inflammation du mélange air/gaz. Le dispositif 4 d'inflammation du mélange air/gaz ne sera pas décrit en détail car il peut être constitué de manière en soi connue d'un dispositif électrique de type résistance, étincelles ou autre, d'une veilleuse ou similaire. Chaque brûleur comporte au moins un dispositif 11 de contrôle de la flamme. Ce dispositif 11 de contrôle de la flamme est ainsi commun à tous les brûleurs. Ce dispositif 11 de contrôle de la flamme peut être constitué d'un dispositif optique, d'un dispositif à ionisation, d'un dispositif à infrarouge ou de tout autre moyen qui assure, lors d'une extinction de la flamme, la fermeture de l'alimentation de la conduite commune d'alimentation en gaz à partir de la source d'alimentation en gaz et ce, au moyen d'une vanne de fermeture appropriée. De préférence, ce dispositif 11 est un dispositif à ionisation constitué d'une sonde et d'une tige métallique venant coiffer le brûleur du milieu et s'étendant le long de chacun des brûleurs jouxtant ce brûleur médian. La coopération de ce dispositif 11 de contrôle de la flamme avec les moyens de commande des brûleurs sera décrite ci-après.In the heating device, object of the invention, there is preferably a distinction two types of burners, namely a so-called master burner, fitted with a device 4 of the air / gas mixture ignition and of the burners 1, called slaves, which differentiate from the master burner by the fact that they are device-free ignition of the air / gas mixture. The device 4 for igniting the mixture air / gas will not be described in detail since it can be constituted in itself known from an electrical device of resistance, sparks or other type, from a night light or the like. Each burner comprises at least one device 11 for flame control. This flame control device 11 is thus common to all burners. This flame control device 11 can be consisting of an optical device, an ionization device, a infrared or any other means which ensures, when the flame, closing the supply to the common supply line gas from the gas supply source by means of a valve appropriate closure. Preferably, this device 11 is a device to ionization consisting of a probe and a metal rod coming to cap the middle burner and extending along each of the burners adjoining this median burner. The cooperation of this flame control device 11 with the burner control means will be described below.
Chaque brûleur 1, maítre ou esclave, est raccordé à la source 3 d'alimentation en gaz par l'intermédiaire de la conduite 2 commune d'alimentation en gaz et d'un piquage sur ladite conduite 2. Chaque portion de liaison 5, réalisée entre la source 3 d'alimentation en gaz et un brûleur 1, est pourvue d'un organe 6 tel qu'une électrovanne assurant l'ouverture ou la fermeture de la liaison 5 entre le brûleur 1 et la source 3 d'alimentation en gaz. Cette ouverture/fermeture de la liaison 5 est commandée au moyen d'un dispositif de commande approprié en fonction de l'étage de puissance sélectionné. En effet, le dispositif de chauffage comporte une pluralité de brûleurs 1. Parmi ces brûleurs, on distingue au moins deux types de brûleurs 1 se différenciant par leur puissance de chauffe. De préférence, le brûleur 1 de plus faible puissance est disposé entre deux autres brûleurs 1.Each burner 1, master or slave, is connected to the power source 3 in gas via the common gas supply line 2 and a tap on said pipe 2. Each connecting portion 5, produced between the source 3 of gas supply and a burner 1, is provided with a member 6 such that a solenoid valve ensuring the opening or closing of the link 5 between the burner 1 and source 3 of gas supply. This opening / closing of the link 5 is controlled by means of a suitable control device in depending on the power stage selected. Indeed, the heater comprises a plurality of burners 1. Among these burners, there are at least two types of burners 1 differentiated by their heating power. Of preferably, the lower power burner 1 is placed between two other burners 1.
Ces brûleurs sont associés en fonctionnement suivant des combinaisons prédéterminées quelconques sélectionnables à volonté et de manière aléatoire par exemple au moyen d'un programmateur, chaque combinaison correspondant à un étage de puissance. Ainsi, il peut être imaginé un dispositif de chauffage comportant quatre brûleurs à puissance de chauffage différenciée. Le premier étage correspond au fonctionnement du brûleur maítre de plus faible puissance, le deuxième étage de puissance à la combinaison du brûleur de plus faible puissance avec le brûleur de puissance immédiatement au-dessus..., le dernier étage correspondant à une combinaison où l'ensemble des brûleurs fonctionnent, c'est-à-dire sont allumés.These burners are associated in operation according to combinations any predetermined randomly selectable for example by means of a programmer, each combination corresponding to a power stage. So it can be imagined a device heater with four burners with heating output differentiated. The first stage corresponds to the operation of the master burner of lower power, the second power stage to the combination of lower power burner with power burner immediately above ..., the top floor corresponding to a combination where the whole burners are working, i.e. are lit.
Le dispositif de chauffage comporte donc en outre des moyens de sélection d'un étage de puissance correspondant à une combinaison prédéterminée de brûleur(s) en fonctionnement parmi une pluralité d'étages. Ces moyens de sélection peuvent être constitués par un programmateur. Ainsi, il peut être choisi, pour un dispositif de chauffage comportant quatre brûleurs, respectivement appelés B1, B2, B3, B4, de définir un premier étage de puissance correspondant à une alimentation en mélange air/gaz de B1, les liaisons des autres brûleurs demeurant fermées. Il peut être défini un deuxième étage de puissance dans lequel seul le brûleur B3 de puissance différente du brûleur B1 est allumé. Il peut être ainsi défini d'autres combinaisons, le nombre total de combinaisons étant au plus égal à 2x, x correspondant au nombre de brûleurs de l'installation. Ainsi, avec trois brûleurs, il peut être possible de définir 8 étages de puissance ou 8 vitesses de chauffe (en incluant l'état zéro où tous les brûleurs sont éteints), avec quatre brûleurs, 16 étages de puissance, etc. Pour permettre d'une part la réduction du nombre de pièces d'un tel dispositif de chauffage et en particulier limiter le nombre de dispositifs 4, 11 d'inflammation de mélange air/gaz et de contrôle de la flamme nécessaires, d'autre part optimiser le fonctionnement du dispositif 11 de contrôle de la flamme, les moyens 7 de commande d'ouverture/fermeture de la liaison de chaque brûleur commandent, lors du passage d'un étage de puissance N à un nouvel étage de puissance P quelconque sélectionné, l'ouverture de l'ensemble des liaisons 5 des brûleurs 1 pour permettre, par inflammation automatique de la flamme d'un brûleur par contact du mélange air/gaz expulsé du brûleur avec la flamme d'un brûleur adjacent, l'allumage de tous les brûleurs puis la fermeture sélective des liaisons 5 des brûleurs non inclus dans la combinaison correspondant au nouvel étage de puissance sélectionné. Ainsi, le fonctionnement peut être résumé comme suit.The heating device therefore further comprises means for selecting a power stage corresponding to a predetermined combination of burner (s) in operation from a plurality of stages. These selection means can be constituted by a programmer. Thus, it can be chosen, for a heating device comprising four burners, respectively called B1, B2, B3, B4, to define a first power stage corresponding to a supply of air / gas mixture of B1, the connections of the other burners remaining closed. A second power stage can be defined in which only the burner B3 of a power different from the burner B1 is lit. Other combinations can thus be defined, the total number of combinations being at most equal to 2 x , x corresponding to the number of burners in the installation. Thus, with three burners, it may be possible to define 8 power stages or 8 heating speeds (including the zero state where all the burners are off), with four burners, 16 power stages, etc. To allow on the one hand the reduction in the number of parts of such a heating device and in particular to limit the number of devices 4, 11 for ignition of air / gas mixture and flame control required, on the other hand optimizing the operation of the flame control device 11, the means 7 for controlling the opening / closing of the connection of each burner control, when passing from a power stage N to any new power stage P selected at any point, the opening of all the connections 5 of the burners 1 to allow, by automatic ignition of the flame of a burner by contact of the air / gas mixture expelled from the burner with the flame of an adjacent burner, the ignition of all the burners then the selective closing of the burner links 5 not included in the combination corresponding to the new selected power stage. Thus, the operation can be summarized as follows.
Supposons un dispositif comportant 4 brûleurs B1 à B4, de puissance
différente disposés côte à côte, 0 correspond à une liaison 5 ouverte du
brûleur, F à une liaison 5 fermée. Ainsi, l'étage de puissance N correspond à un
étage où seul le brûleur B1 fonctionne tandis que l'étage de puissance P
correspond à un étage où seul le brûleur B3 fonctionne. Au cours du passage
de l'étage de puissance N à l'étage de puissance P, il est nécessaire d'ouvrir la
liaison 5 des brûleurs B2, B3, B4 pour permettre l'inflammation de B3 puis de
fermer sélectivement les liaisons 5 des brûleurs B1, B2 et B4 pour obtenir la
combinaison de brûleur(s) retenue à l'étage de puissance P.
Cette solution permet de s'affranchir de moyens de mémorisation des combinaisons de brûleurs couplés aux moyens 7 de commande de l'ouverture/fermeture des liaisons. Ainsi, entre chaque passage d'un étage de puissance à un autre, l'ensemble des brûleurs est mis en fonctionnement par ouverture automatique des liaisons 5. D'autre part, cette solution permet de garantir l'activation du dispositif 11 de contrôle de la flamme par l'un quelconque des brûleurs, quel que soit le niveau de puissance sélectionné. En effet, lorsque le niveau de puissance sélectionné correspond à l'allumage d'un brûleur de faible puissance et que ce brûteur se trouve à l'opposé du brûleur allumé à l'étage de puissance N-1, il n'est pas garanti, si l'on procède simplement à un allumage de proche en proche des brûleurs en ne mettant en fonctionnement que les brûleurs séparant le brûleur de l'étage de puissance N-1 du brûleur de l'étage de puissance N, que le dispositif de contrôle de la flamme présente une température suffisante après extinction des brûleurs une fois la transition opérée. En conséquence et pour garantir la mise en température de ce dispositif de contrôle de la flamme quels que soient les étages de puissance sélectionnés, le fait de mettre en fonctionnement l'ensemble des brûleurs au cours de la période de transition et le passage d'un étage de puissance à un autre permet d'assurer cette mise en température du dispositif de contrôle de la flamme ou de dégager une chaleur suffisante pour permettre un fonctionnement optimal de ce dispositif de contrôle de la flamme. Il devient ainsi possible, grâce à ce mode de fonctionnement, de passer d'un étage de puissance à un autre en choisissant un premier brûleur positionné à l'étage de puissance N-1 et un brûleur positionné de manière très éloignée du premier brûleur à l'étage de puissance N, ce second brûleur étant un brûleur de faible puissance.This solution makes it possible to dispense with means of memorizing the combinations of burners coupled to means 7 for controlling opening / closing links. Thus, between each passage of a stage of power to another, all the burners are put into operation by automatic opening of links 5. On the other hand, this solution allows guarantee activation of the flame control device 11 by one any of the burners, regardless of the power level selected. In effect, when the power level selected corresponds to the ignition of a low-power burner and this burner is opposite the burner lit on power stage N-1, it is not guaranteed, if one proceeds simply a lighting step by step near the burners by not putting in operation as the burners separating the burner from the power stage N-1 of the burner of the power stage N, that the device for controlling the flame has a sufficient temperature after extinguishing the burners a once the transition has taken place. Consequently and to guarantee the implementation temperature of this flame control device whatever the selected power stages, switching on all of the burners during the transition period and the passage of a power stage to another ensures this warming up of the flame control device or give off sufficient heat to allow optimal operation of this flame control device. It thus becomes possible, thanks to this operating mode, to switch from one power stage to another by choosing a first burner positioned at the power stage N-1 and a burner positioned very far from the first burner on the power stage N, this second burner being a burner of weak power.
L'organe 6 d'obturation à ouverture/fermeture commandée de la liaison 5 entre un brûleur 1 et la source 3 d'alimentation en gaz est une électrovanne. L'ouverture/fermeture des électrovannes peut être commandée au moyen de signaux électriques émis à partir d'informations émanant d'une centrale de commande, telle qu'un microprocesseur. Cette centrale gère les informations relatives à l'étage de puissance sélectionné pour déterminer les liaisons devant être ouvertes ou respectivement fermées.The controlled opening / closing shutter member 6 of the link 5 between a burner 1 and the gas supply source 3 is a solenoid valve. The opening / closing of the solenoid valves can be controlled by means of electrical signals emitted from information emanating from a central control, such as a microprocessor. This central manages information relating to the power stage selected to determine the connections in front be open or closed respectively.
Pour permettre un fonctionnement optimisé d'un tel dispositif, l'intervalle entre deux têtes de brûleurs adjacents est choisi de manière à permettre l'auto-inflammation de deux brûleurs adjacents en moins de un dixième de seconde.To allow optimized operation of such a device, the interval between two adjacent burner heads is chosen so as to allow self-ignition two adjacent burners in less than a tenth of a second.

également être constitué des fumées de la chambre 8 de combustion. Lorsque
la première hypothèse est retenue, les fumées, contenues à l'intérieur de la
chambre 8 de combustion, sont canalisées et rejetées dans l'atmosphère.In the examples shown in Figure 1, the burners 1 are arranged at
