Description

Domaine techniqueTechnical area

L'invention se rapporte à un brûleur à air soufflé, comprenant plus particulièrement une tête de combustion montée sur un carter en s'étendant suivant une direction axiale, une turbine de ventilation montée autour d'un axe de rotation fixe par rapport au carter et un diffuseur dirigeant un flux d'air comburant généré par la turbine de ventilation vers la tête de combustion.The invention relates to a forced air burner, comprising more particularly a combustion head mounted on a housing extending next an axial direction, a ventilation turbine mounted around an axis of rotation fixed relative to the housing and a diffuser directing a combustion air flow generated by the ventilation turbine to the combustion head.

Etat de la techniqueState of the art

On connaít notamment du document US 2 986 207, des brûleurs de ce type dans lesquels la turbine de ventilation et le diffuseur s'étendent dans un plan du carter perpendiculaire à l'axe de rotation et perpendiculaire à la direction axiale de la tête de combustion. Cet agencement impose un coude à angle droit au diffuseur ce qui entraíne une perte de charge importante du flux d'air soufflé à l'entrée de la tête de combustion.US Pat. No. 2,986,207 discloses burners of this type. type in which the ventilation turbine and the diffuser extend in a plane of the housing perpendicular to the axis of rotation and perpendicular to the axial direction of the combustion head. This arrangement imposes a right angle bend at diffuser which causes a significant pressure drop of the air flow blown to the inlet of the combustion head.

Pour d'autres brûleurs connus de ce type, notamment du document FR 949132, US 5 415 539 ou FR 766266, la turbine de ventilation et le diffuseur s'étendent dans un plan du carter perpendiculaire à l'axe de rotation et parallèle à la direction axiale de la tête de combustion. Cet agencement permet un bon écoulement du flux d'air soufflé vers la tête de combustion. Toutefois, il ne favorise pas l'accès à la tête de combustion : il est en général nécessaire de prévoir un mécanisme, par exemple à glissières ou à charnières, permettant au carter d'être déplacé pour dégager la tête de combustion lors d'opérations de maintenance. Dans le cas particulier du document FR 766266, on prévoit d'accéder à la tête de combustion par un tronçon du diffuseur à l'extérieur au carter et coudé à angle droit. Cet agencement introduit une perte de charge du flux d'air soufflé vers la tête de combustion et augmente l'encombrement du brûleur entre le carter et la tête de combustion.For other known burners of this type, in particular of the document FR 949132, US 5 415 539 or FR 766266, the ventilation turbine and the diffuser extend in a plane of the casing perpendicular to the axis of rotation and parallel to the axial direction of the combustion head. This arrangement allows a good flow of the blown air flow to the combustion head. However, it does not favor access to the combustion head: it is generally necessary to provide a mechanism, for example with slides or hinges, allowing the casing to be moved to disengage the combustion head during maintenance operations. In the particular case of FR 766266, provision is made to access the head of combustion by a section of the diffuser outside the housing and bent at right angles. This arrangement introduces a pressure drop of the flow of air blown towards the head of combustion and increases the size of the burner between the housing and the head of combustion.

On connaít enfin du document GB 2233439 un brûleur de ce type dans lequel le diffuseur est disposé pour une raison de compacité dans le carter sur lequel la tête de combustion est montée et s'étend dans un plan du carter perpendiculaire à l'axe de rotation de la turbine de ventilation en étant incliné par rapport à la direction axiale de la tête de combustion d'un angle d'inclinaison voisin de 45 degrés. Cet agencement permet d'accéder à la tête de combustion sans déplacer le carter sur lequel elle est montée. Toutefois, l'inclinaison du diffuseur par rapport au carter conduit là encore à augmenter la perte de charge du flux d'air soufflé par la turbine de ventilation.Finally, document GB 2233439 discloses a burner of this type in which the diffuser is arranged for a reason of compactness in the housing on which the combustion head is mounted and extends in a plane of the housing perpendicular to the axis of rotation of the ventilation turbine by being inclined by ratio to the axial direction of the combustion head of a neighboring angle of inclination 45 degrees. This arrangement allows access to the combustion head without move the casing on which it is mounted. However, the inclination of the diffuser by compared to the crankcase again leads to increase the pressure drop of the air flow blown by the ventilation turbine.

Le but de l'invention est de modifier un brûleur du type rappelé ci-dessus pour améliorer l'écoulement du flux d'air soufflé par la turbine de ventilation.The object of the invention is to modify a burner of the type recalled above to improve the flow of the air flow blown by the ventilation turbine.

Divulgation de l'inventionDisclosure of the invention

A cet effet, l'invention a pour objet un brûleur du type décrit précédemment, caractérisé en ce que le diffuseur s'étend dans le plan du carter perpendiculaire à l'axe de rotation, suivant une direction de diffusion faisant un angle de diffusion compris entre 10 et 50 degrés, de préférence entre 20 et 50 degrés, avec une projection de la direction axiale de la tête de combustion dans le plan perpendiculaire à l'axe de rotation de la turbine de ventilation. Par cet agencement, on supprime tout point d'arrêt du flux d'air soufflé dans le diffuseur tout en lui conservant l'inclinaison par rapport à la tête de combustion.For this purpose, the subject of the invention is a burner of the type described previously, characterized in that the diffuser extends in the plane of the housing perpendicular to the axis of rotation, in a direction of diffusion making a diffusion angle between 10 and 50 degrees, preferably between 20 and 50 degrees, with a projection of the axial direction of the combustion head into the plane perpendicular to the axis of rotation of the ventilation turbine. By this arrangement, it removes any stopping point of the air flow blown into the diffuser while by keeping it inclined with respect to the combustion head.

Autrement dit, on favorise à la fois l'écoulement du flux d'air soufflé vers la tête de combustion tout en permettant une bonne accessibilité de la tête de combustion ne nécessitant pas de déplacer le carter lors d'opérations de maintenance de la tête de combustion.In other words, it promotes both the flow of the air flow blown towards the combustion head while allowing a good accessibility of the head of combustion does not require the crankcase to be moved during maintenance of the combustion head.

Avantageusement, des composants de réglage ou de commande électrique sont disposés sur une face du carter parallèle au plan perpendiculaire à l'axe de rotation pour être facilement accessibles et ainsi augmenter encore l'ergonomie du brûleur. Lorsque la direction axiale de la tête de combustion s'étend horizontalement, cette face du carter inclinée par exemple entre 10 et 50 degrés par rapport à l'horizontale est très pratique pour effectuer des contrôles visuels ou des démontages.Advantageously, adjustment or control components electrical system are arranged on a face of the casing parallel to the plane perpendicular to the axis of rotation to be easily accessible and so further increase the ergonomics of the burner. When the axial direction of the combustion head extends horizontally, this face of the casing inclined for example between 10 and 50 degrees by horizontal report is very convenient for performing visual checks or disassembly.

    En référence aux figures 1 à 3, un brûleur à air soufflé, comprend une tête de combustion 1 montée sur un carter 3 en s'étendant suivant une direction axiale A, par exemple horizontale, et une turbine de ventilation 5 montée dans une volute 7 du carter autour d'un axe de rotation 9 fixe par rapport au carter. La tête de combustion et la volute communiquent entre elles par l'intermédiaire d'un diffuseur 11 du carter, par exemple formé par une partie du carter lui-même disposée en sortie de la volute, pour diriger un flux d'air comburant généré par la turbine de ventilation vers la tête de combustion.With reference to FIGS. 1 to 3, a forced-air burner comprises a combustion head 1 mounted on a housing 3 extending in one direction axial axis A, for example horizontal, and a ventilation turbine 5 mounted in a casing volute 7 about an axis of rotation 9 fixed relative to the housing. The head of combustion and the volute communicate with each other via a diffuser 11 of the housing, for example formed by a portion of the housing itself arranged in output of the volute, to direct a flow of combustion air generated by the turbine of ventilation to the combustion head.

    La volute 7 et le diffuseur 11 s'étendent dans un plan P du carter perpendiculaire à l'axe de rotation 9 et incliné par rapport à la direction axiale A de la tête de combustion 1. Le plan P perpendiculaire à l'axe de rotation 9 et la direction axiale A forment de préférence entre eux un angle a d'inclinaison compris entre 10 et 50 degrés. D'une façon connue en soi, la tête de combustion 1 est alimentée en combustible liquide ou gazeux par un circuit d'alimentation non représenté. Dans le cas d'un combustible liquide, ce circuit comprend une pompe débitant dans un système d'atomisation du combustible liquide à l'intérieur de la tête de combustion 1.The volute 7 and the diffuser 11 extend in a plane P of the casing perpendicular to the axis of rotation 9 and inclined with respect to the axial direction A of the combustion head 1. The plane P perpendicular to the axis of rotation 9 and the axial direction A preferably form between them an angle of inclination incl between 10 and 50 degrees. In a manner known per se, the combustion head 1 is supplied with liquid or gaseous fuel by a non-feed circuit represent. In the case of a liquid fuel, this circuit comprises a pump debiting in a liquid fuel atomization system inside the head of combustion 1.

    Selon l'invention, le diffuseur 11, dans le plan P perpendiculaire à l'axe de rotation 9, s'étend suivant une direction de diffusion D faisant un angle de diffusion b compris entre 10 et 50 degrés, de préférence entre 20 et 50 degrés, avec la projection de la direction axiale A de la tête de combustion 1 dans le plan P.According to the invention, the diffuser 11, in the plane P perpendicular to the axis of rotation 9, extends in a diffusion direction D making an angle of diffusion b between 10 and 50 degrees, preferably between 20 and 50 degrees, with the projection of the axial direction A of the combustion head 1 in the plane P.

    Un angle de diffusion supérieur à 50 degrés augmente trop la perte de charge du diffuseur en comparaison du gain de compacité suivant la direction axiale de la tête de combustion. Un angle de diffusion inférieur à 10 degrés augmente trop à l'inverse l'encombrement suivant la direction axiale de la tête de combustion en comparaison de la réduction de la perte de charge du diffuseur. An angle of diffusion greater than 50 degrees increases the loss of charge of the diffuser in comparison with the compactness gain in the axial direction of the combustion head. An angle of diffusion less than 10 degrees increases too much conversely the space in the axial direction of the combustion head in comparison of the reduction of the pressure drop of the diffuser.

    Des composants 13 de réglage, de commande électrique ou d'alimentation en combustible sont disposés sur une face 15 du carter 3 parallèle au plan P perpendiculaire à l'axe de rotation 9.13 control components, electrical control or fuel supply are arranged on a face 15 of the casing 3 parallel to the plane P perpendicular to the axis of rotation 9.

    Application industrielleIndustrial application

    Le brûleur selon l'invention est assemblé à partir d'un carter par exemple fabriqué d'une seule pièce par un procédé de fonderie. Après avoir disposé le turbine de ventilation dans la volute autour de l'axe de rotation, le carter est fermé par un couvercle formant la face opposée à celle qui est destinée à recevoir les composants de réglage, de commande électrique ou d'alimentation en combustible.The burner according to the invention is assembled from a housing by example manufactured in one piece by a foundry process. After having arranged the ventilation turbine in the volute around the axis of rotation, the housing is closed by a cover forming the face opposite to that which is intended to receive the adjusting, electrical control or fuel supply components.

    L'air soufflé par la turbine de ventilation est dirigé par le diffuseur vers la tête de combustion pour être mélangé à un combustible. Le mélange du combustible et du comburant est enflammé.
