Abstract
Description
La présente invention concerne une nouvelle chambre pour la combustion pulsatoire, ladite chambre devant permettre la combustion pulsatoire d'un mélange de combustible et de comburant.The present invention relates to a new chamber for pulsating combustion, said chamber having to allow the pulsating combustion of a mixture of fuel and oxidant.
Le principe de la combustion pulsatoire et son utilisation pour la réalisation d'installations de chauffage est connu de l'Homme de l'Art. Il est en particulier décrit dans le brevet français 2 178 997 du 2 avril 1973. Dans de telles installations, la chambre principale est munie d'un ensemble de chambres latérales, d'une plaque transversale divisant la chambre principale en deux compartiments tel que le mélange de combustible et de comburant qui pénètre dans le premier de ces compartiments, en direction de la plaque transversale, soit divisé par cette plaque et soit obligé, pour passer derrière celle-ci, de traverser les chambres latérales.The principle of pulsed combustion and its use for the realization of heating installations is known to those skilled in the art. It is in particular described in French patent 2,178,997 of April 2, 1973. In such installations, the main chamber is provided with a set of lateral chambers, with a transverse plate dividing the main chamber into two compartments such as the mixture of fuel and oxidizer which enters the first of these compartments, in the direction of the transverse plate, is divided by this plate and is forced, to pass behind it, to pass through the lateral chambers.
Selon la réalisation particulière décrite dans le brevet précité, la chambre principale comporte quatre chambres latérales, réparties autour de l'axe reliant l'orifice d'entrée à l'orifice de sortie et la plaque transversale est fixée aux parois de la chambre. Cet ensemble est réalisé d'un seul tenant lors des opérations de fonderie.According to the particular embodiment described in the aforementioned patent, the main chamber has four lateral chambers, distributed around the axis connecting the inlet orifice to the outlet orifice and the transverse plate is fixed to the walls of the chamber. This set is made in one piece during foundry operations.
Il est aussi prévu que la plaque et la chambre soient solidarisées entre elles en plusieurs endroits, ce qui doit permettre un meilleur transport de chaleur à la paroi de la chambre principale. Ces zones de fixation sont réparties aux endroits de la paroi de la chambre principale qui se situent entre les chambres latérales.It is also expected that the plate and the chamber are joined together in several places, which should allow better heat transport to the wall of the main chamber. These fixing zones are distributed at the locations of the wall of the main chamber which are located between the lateral chambers.
Il est connu également par le brevet allemand DE-AI-3 337 048 un système de chauffage à combustion pulsatoire ou la chambre de combustion peut être réalisée en deux parties soudées entre elles.It is also known from German patent DE-AI-3 337 048 a pulsed combustion heating system or the combustion chamber can be made in two parts welded together.
La séparation en deux compartiments de la chambre de combustion pose un problème, fréquemment rencontré, qui est celui de dilatation différentielle qui peut exister entre la plaque de séparation et les parois de la chambre puisque ces éléments peuvent être portés à des températures très différentes. De façon à remédier à ces problèmes, on a proposé dans la demande de brevet PCT WO 81/00610 de munir la plaque transversale de zones d'affaiblissement situées le long de deux axes perpendiculaires se croisant au centre de la plaque. En fonctionnement, et en particulier lors de la mise en combustion de la chambre, la plaque est rompue selon ces lignes et accepte donc des variations dimensionelles dues aux écarts de température tout en continuant de jouer son rôle de plaque de séparation.The separation into two compartments of the combustion chamber poses a problem, frequently encountered, which is that of differential expansion which may exist between the separation plate and the walls of the chamber since these elements can be brought to very different temperatures. In order to remedy these problems, it has been proposed in PCT patent application WO 81/00610 to provide the transverse plate with weakening zones situated along two perpendicular axes crossing at the center of the plate. In operation, and in particular during the combustion of the chamber, the plate is broken along these lines and therefore accepts dimensional variations due to temperature differences while continuing to play its role of separation plate.
Pour utiliser ces chambres de combustion dans des chaudières complètes, on réunit tous les éléments entre eux par des opérations de soudure et de brasage, ce qui peut occasionner certains problèmes lors du fonctionnement, en particulier au niveau de la liaison entre l'échangeur tubulaire et la corne qui assure le passage des gaz brûlés et chauds entre la chambre et l'échangeur.To use these combustion chambers in complete boilers, all the elements are joined together by welding and brazing operations, which can cause certain problems during operation, in particular at the connection between the tubular exchanger and the horn which ensures the passage of burnt and hot gases between the chamber and the exchanger.
Un premier but de l'invention est de prévoir une chambre de combustion qui permette une réalisation simple et qui, une fois montée, ne présente pas de problèmes d'étanchéité.A first object of the invention is to provide a combustion chamber which allows a simple realization and which, once assembled, does not present sealing problems.
Un deuxième but de l'invention est de prévoir une chambre de combustion qui résolve aussi le problème de la dilatation différentielle entre la plaque et la chambre.A second object of the invention is to provide a combustion chamber which also solves the problem of differential expansion between the plate and the chamber.
Pour cela, l'invention prévoit un nouvel ensemble pour la combustion pulsatoire comportant au moins une chambre de combustion pulsatoire se présentant sous la forme d'une chambre principale et d'au moins deux chambres latérales caractérisé en ce qu'il est constitué par au moins deux coquilles conformées par emboutissage et reliées entre elles par soudage, chacune desdite coquilles comportant, au niveau de la chambre principale, des moyens de fixation constitués par des cavités embouties dans lesquelles est ajustée une plaque de séparation avec un jeu minimum autorisant son déplacement transversal.For this, the invention provides a new assembly for pulsating combustion comprising at least one pulsating combustion chamber in the form of a main chamber and at least two side chambers characterized in that it is constituted by at at least two shells shaped by stamping and connected together by welding, each of said shells comprising, at the level of the main chamber, fixing means constituted by stamped cavities in which a separation plate is adjusted with a minimum clearance allowing its transverse displacement .
Selon un mode particulier de réalisation, ledit ensemble comporte aussi au moins une partie d'un échangeur tubulaire plat et une corne de liaison entre ladite chambre et ladite partie de l'échangeur, il est alors caractérisé en ce qu'il est réalisé en deux coquilles qui sont assemblées selon le plan général de l'échangeur.According to a particular embodiment, said assembly also comprises at least part of a flat tubular exchanger and a connecting horn between said chamber and said part of the exchanger, it is then characterized in that it is produced in two shells which are assembled according to the general plan of the exchanger.
Selon une caractéristique complémentaire de l'invention, l'ensemble comporte la totalité de l'échangeur plat, cet échangeur comportant une chambre de découplage dans laquelle débouchent tous les tubes de l'échangeur tubulaire.According to an additional characteristic of the invention, the assembly comprises the entire flat exchanger, this exchanger comprising a decoupling chamber into which open all the tubes of the tubular exchanger.
On comprend donc que selon l'invention on peut réaliser.facilement un ensemble complet, monobloc, par réunion de deux plaques embouties.It is therefore understood that according to the invention it is possible to easily make a complete, monobloc assembly, by joining two stamped plates.
Selon un mode préféré de réalisation, ces moyens de fixation sont constitué par des cavités réalisées lors de l'emboutissage où peut être montée la plaque intermédiaire.According to a preferred embodiment, these fixing means consist of cavities produced during stamping where the intermediate plate can be mounted.
En outre, selon un mode particulier de réalisation de l'invention, la chambre de combustion comporte quatre chambres latérales réparties autour de la chambre principale, chaque chambre latérale étant située à proximité immédiate de deux autres chambres, de sorte que chaque paroi d'une chambre est sensiblement en contact avec une paroi d'une chambre voisine, la zone de contact de ces deux parois définissant chacune une partie de la paroi de la chambre centrale, et les cavités sont situées dans lesdites parties de la paroi de la chambre principale.In addition, according to a particular embodiment of the invention, the combustion chamber comprises four lateral chambers distributed around the main chamber, each lateral chamber being located in the immediate vicinity of two other chambers, so that each wall of a chamber is substantially in contact with a wall of a neighboring chamber, the contact zone of these two walls each defining a part of the wall of the central chamber, and the cavities are located in said parts of the wall of the main chamber.

On a représenté sur la figure 1, un ensemble (1) réalisé selon l'invention. Il comporte une chambre de combustion (2), un échangeur tubulaire (3) plat, dont on n'a représenté que la partie supérieure. La chambre de combustion (2) et l'échangeur tubulaire sont reliés entre eux par une corne (4) établissant un passage pour les gaz de combustion.FIG. 1 shows an assembly (1) produced according to the invention. It comprises a combustion chamber (2), a flat tubular exchanger (3), of which only the upper part has been shown. The cham combustion flue (2) and the tubular exchanger are connected together by a horn (4) establishing a passage for the combustion gases.
La chambre de combustion (2) comporte quatre chambres latérales, telles que (5) et une chambre centrale (6) située entre la tubulure d'entrée (7) et la corne (4).The combustion chamber (2) has four lateral chambers, such as (5) and a central chamber (6) located between the inlet pipe (7) and the horn (4).
La figure 2 est une demi-vue de dessus de la chambre (2). Entre les chambres latérales telles que (5), (5a) et (5b), on a représenté les parois supérieures (10) et (11) des zones pincées. Ainsi qu'il apparaît mieux sur la coupe de la figure 3, chaque paroi supérieure telles que (10) et (11 ) est associée à une paroi inférieure telle que (12) et définit avec elle le logement (14) dans lequel est logée la plaque de séparation (13). Le longement (14) a la forme d'une cavité réalisée par emboutissage.Figure 2 is a half top view of the chamber (2). Between the lateral chambers such as (5), (5a) and (5b), the upper walls (10) and (11) of the pinched areas are shown. As it appears better on the section of FIG. 3, each upper wall such as (10) and (11) is associated with a lower wall such as (12) and defines with it the housing (14) in which is housed the separation plate (13). The extension (14) has the shape of a cavity produced by stamping.
Chaque chambre latérale telle que (5) et (5a) comporte des parois latérales (51, 52, 53 et 54), ou encore (54a). Les parois consécutives (53) et (54a) se rejoignent dans la zone (55) qui définit partiellement la paroi de la chambre centrale (6).Each side chamber such as (5) and (5a) has side walls (51, 52, 53 and 54), or also (54a). The consecutive walls (53) and (54a) meet in the area (55) which partially defines the wall of the central chamber (6).
Les logements tels que (14) sont situés dans la zone (55) et s'étendent chacun entre deux parois consécutives (53 et 54a).The housings such as (14) are located in the zone (55) and each extend between two consecutive walls (53 and 54a).
La plaque (13) est ajustée de façon à avoir un jeu minimum entre ses éxtrémités et les fonds des logements (14). Selon la réalisation présentée le contact entre la plaque et le logement (14) est quasi linéaire mais on pourrait donner toute forme aux parois (10) et (12) qui permettrait une surface de contact plus ou moins étendue.The plate (13) is adjusted so as to have a minimum clearance between its ends and the bottoms of the housings (14). According to the embodiment presented the contact between the plate and the housing (14) is almost linear but one could give any shape to the walls (10) and (12) which would allow a more or less extensive contact surface.
On obtient ainsi une fixation ferme de la plaque mais qui autorise les mouvements transversaux. Par exemple, la plaque peut se dilater puisque sous l'effet d'une telle dilatation les parois (10) et (11) des logements (14) vont s'écarter.A firm fixing of the plate is thus obtained, but which allows transverse movements. For example, the plate can expand since under the effect of such expansion the walls (10) and (11) of the housings (14) will move apart.
Pour réaliser l'ensemble représenté en perspective sur la figure 1 et en vue de face et de côté sur les figures 4 et 5, on part de deux plaques d'acier inoxydable que l'on emboutit selon les techniques usuelles pour réaliser deux demi-ensembles (18) et (19).To make the assembly shown in perspective in FIG. 1 and in front and side view in FIGS. 4 and 5, one starts with two stainless steel plates which are stamped according to the usual techniques to produce two half sets (18) and (19).
Après mise en place de la plaque de séparation (13) à l'intérieur d'une demi-chambre par insertion dans les cavités (14) et (14a), on immobilise la plaque (13) dans une des cavités en réalisant un point de soudure. Les deux demi-ensembles emboutis sont ensuite réunis et soudés à la molette sur toute leur longueur selon une bande (25) représentée figure (1After placing the separation plate (13) inside a half-chamber by insertion into the cavities (14) and (14a), the plate (13) is immobilized in one of the cavities by making a point Welding. The two stamped half-assemblies are then joined and welded to the wheel over their entire length according to a strip (25) shown in figure (1
Selon une variante, dans la partie supérieure cylindrique (26) correspondant à la tubulure d'entrée (7), on supprime la languette (25) et effectue la liaison par une soudure TIG (Tungsten Inert Gas) qui permet de reconstituer un cylindre parfait et simplifie la liaison de l'ensemble ainsi obtenu avec les autres organes de la chaudière. L'ensemble réalisé est ainsi parfaitement étanche.According to a variant, in the cylindrical upper part (26) corresponding to the inlet pipe (7), the tongue (25) is removed and the connection is made by a TIG (Tungsten Inert Gas) weld which makes it possible to reconstitute a perfect cylinder. and simplifies the connection of the assembly thus obtained with the other members of the boiler. The assembly produced is thus perfectly sealed.
Lors de cette opération, on réalise avantageusement l'échangeur (3) dont une coupe selon l'axe VI. VI de la figure 5 est représentée figure 6. Les bords (20) et (21) sont soudés par le même cordon de soudure T.I.G. (30). Les deux demi-plaques ont été embouties de façon à définir chacune une série de demi-tubes tels que (31, 33) et (37, 34), chaque demi-tube tel que (31,37) étant séparé du demi-tube voisin tels que (33, 34) par une bande plate (35, 36). Pour réaliser l'étanchéité de l'échangeur et éviter que les tubes ne communiquent entre eux, on effectue sur chaque bande plate une soudure à la mollette.During this operation, the exchanger (3) is advantageously produced, including a section along the axis VI. VI of Figure 5 is shown in Figure 6. The edges (20) and (21) are welded by the same weld bead T.I.G. (30). The two half-plates have been stamped so as to each define a series of half-tubes such as (31, 33) and (37, 34), each half-tube such as (31.37) being separated from the half-tube neighbor such as (33, 34) by a flat strip (35, 36). To seal the exchanger and prevent the tubes from communicating with each other, a seam weld is made on each flat strip.
Mais selon l'invention, on peut avantageusement encore réaliser un ensemble comportant un échangeur complet constitué par la partie supérieure (3), la partie centrale (30), la partie inférieure (31) et une chambre de découplage (32).However, according to the invention, it is advantageously still possible to produce an assembly comprising a complete exchanger constituted by the upper part (3), the central part (30), the lower part (31) and a decoupling chamber (32).
La chambre de découplage (32) est constituée par une paroi cylindrique, une paroi circulaire constituant un fond et une paroi de liaison entre les tubes et l'intérieur de la chambre. Elle est perpendiculaire au plan général de l'échangeur.The decoupling chamber (32) consists of a cylindrical wall, a circular wall constituting a bottom and a connecting wall between the tubes and the interior of the chamber. It is perpendicular to the general plane of the exchanger.
La chambre est réalisée comme le reste de l'ensemble lors de l'emboutissage des demi-plaques et la plaque de fond est rapportée et soudée. Elle comporte une tubulure (50) pour la sortie des gaz.The chamber is made like the rest of the assembly during the stamping of the half-plates and the bottom plate is attached and welded. It comprises a tube (50) for the outlet of the gases.
L'intérêt d'une telle réalisation est d'avoir une liaison continue entre les tubes et la chambre.The advantage of such an embodiment is to have a continuous connection between the tubes and the chamber.
La partie centrale (30) de l'échangeur peut avoir toute forme et par exemple on pourra prévoir une forme telle que la chambre de découplage soit située en dessous de la chambre (5) et ne soit pas décalée comme cela est représenté figure 4.The central part (30) of the exchanger can have any shape and, for example, a shape could be provided such that the decoupling chamber is located below the chamber (5) and is not offset as shown in FIG. 4.
Il est bien entendu que l'on peut utiliser tout autre mode de fixation des demi-plaques sans sortir du cadre de l'invention. On peut aussi réaliser l'ensemble à l'aide de plus de deux plaques.It is understood that one can use any other method of fixing the half-plates without departing from the scope of the invention. We can also make the assembly using more than two plates.
