Description
La présente invention concerne une chaudière à condensation par voie sèche. Dans la suite, on considérera plus particulièrement la réalisation d'une telle chaudière équipée d'un brûleur à gaz, bien que la chaudière suivant l'invention puisse également être utilisée avec des brûleurs à combustible liquide. The present invention relates to a dry condensing boiler. In the following, we will consider more particularly the production of such a boiler equipped with a gas burner, although the boiler according to the invention can also be used with liquid fuel burners.
En pratique, une chaudière à condensation par voie sèche est une chaudière dans laquelle les gaz de combustion, essentiellement du gaz carbonique et de l'eau, cèdent leurs calories à travers un échangeur de chaleur surdimensionné au point que la température de sortie des gaz de combustion descend au-dessous du point de rosée. A titre indicatif, une telle chaudière est décrite dans le demande de brevet FR-A-2 508 608 ou FR-A-2 515 321. In practice, a dry condensing boiler is a boiler in which the combustion gases, mainly carbon dioxide and water, transfer their calories through an oversized heat exchanger to the point that the outlet temperature of the combustion drops below the dew point. As an indication, such a boiler is described in patent application FR-A-2 508 608 or FR-A-2 515 321.
Un objet de la présente invention consiste à prévoir une chaudière à condensation qui soit d'un prix de revient faible, tout en ayant une bonne efficacité. An object of the present invention is to provide a condensing boiler which is of a low cost price, while having good efficiency.
Dans la demande de brevet FR-A-2 508 608, on a décrit une chaudière à condensation à tubes de fumée qui est légèrement inclinée par rapport à l'horizontale. La chambre de combustion de cette chaudière est en forme de pot à fond plein autour duquel est prévue une chemise annulaire d'eau qui est traversée par un faisceau de tubes d'échange de chaleur conduisant les gaz chauds de combustion de la sortie de la chambre de combustion vers le conduit de sortie des fumées. In patent application FR-A-2 508 608, a smoke tube condensing boiler has been described which is slightly inclined relative to the horizontal. The combustion chamber of this boiler is in the form of a pot with a solid bottom around which is provided an annular jacket of water which is crossed by a bundle of heat exchange tubes leading the hot combustion gases from the outlet of the chamber. combustion to the flue outlet.
Dans la demande de brevet FR-6-2 515 321, on a décrit une chaudière à condensation, également à tubes de fumée, dans laquelle la chambre de combustion est un pot cylindrique à axe vertical dont le fond laisse passer une partie des fumées directement vers une nappe d'eau de condensation. Etant donné cette disposition, l'eau de condensation est à température relativement élevée, ce qui ne permet pas une condensation poussée des fumées. In patent application FR-6-2 515 321, a condensing boiler, also with smoke tubes, has been described, in which the combustion chamber is a cylindrical pot with vertical axis, the bottom of which allows part of the smoke to pass directly towards a water table of condensation. Given this arrangement, the condensation water is at a relatively high temperature, which does not allow extensive condensation of the fumes.
Dans le certificat d'utilité FR-A-2 458 765, il est prévu une chaudière à chemise d'eau comportant des échangeurs de chaleur supplémentaires transversaux placés entre la sortie des gaz de fumée de la zone d'échange principal et le conduit de fumée. La chemise d'eau principale est en communication avec l'eau des échangeurs supplémentaires. I1 en résulte que l'eau des échangeurs supplémentaires est à une température relativement élevée. In the utility certificate FR-A-2 458 765, there is provided a water jacket boiler comprising additional transverse heat exchangers placed between the flue gas outlet of the main exchange zone and the smoke. The main water jacket is in communication with the water of the additional exchangers. As a result, the water in the additional exchangers is at a relatively high temperature.
Un autre objet de l'invention consiste à prévoir une chaudière à condensation à tubes de fumées et à chambre de combustion en forme de pot à fond plein orienté verticalement, qui permette une meilleure condensation des gaz de fumée. Another object of the invention consists in providing a condensing boiler with smoke tubes and combustion chamber in the shape of a pot with a solid bottom oriented vertically, which allows better condensation of the smoke gases.
Suivant une caractéristique de l'invention, entre les sorties des tubes de fumée et le conduit de fumée, est prévu un échangeur de chaleur alimenté par de l'eau, l'entrée de l'échangeur étant reliée à l'alimentation en eau potable et sa sortie étant reliée à l'entrée du ballon de chauffage de l'eau sanitaire. According to a characteristic of the invention, between the outlets of the smoke tubes and the flue, there is provided a heat exchanger supplied with water, the inlet of the exchanger being connected to the supply of drinking water. and its outlet being connected to the inlet of the domestic water heating tank.
Suivant une autre caractéristique, ledit échangeur est placé au-dessous des sorties des tubes de fumée. According to another characteristic, said exchanger is placed below the exits of the smoke tubes.
Suivant une autre caractéristique, l'échangeur est constitué par du tube flexible onduleux en acier inoxydable. According to another characteristic, the exchanger consists of flexible corrugated stainless steel tube.
I1 faut bien comprendre que l'utilisation d'un échangeur alimenté par l'eau froide du réseau de distribution permet d'abaisser la température des fumées sortant de la chaudière, donc d'améliorer son efficacité. De plus, comme l'échangeur se trouve sous les sorties des tubes de fumées, il reçoit partiellement les produits de condensation s'écoulant de ceux-ci et donc permet de-recueillir une partie des calories qu'ils contiennent. I1 est donc important que l'échangeur soit placé verticalement au-dessous de la partie centrale de la chaudière. It must be clearly understood that the use of an exchanger supplied with cold water from the distribution network makes it possible to lower the temperature of the fumes leaving the boiler, therefore improving its efficiency. In addition, as the exchanger is located under the exits of the smoke tubes, it partially receives the condensation products flowing from them and therefore makes it possible to collect part of the calories they contain. It is therefore important that the exchanger is placed vertically below the central part of the boiler.
Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaîtront plus clairement à la lecture de la description d'un exemple de réalisation, ladite description étant faite en relation avec les dessins joints, parmi lesquels:
la Fig. 1 est une vue schématique en coupe verticale d'une chaudière suivant l'invention, et
la Fig. 2 est une vue éclatée en perspective d'une réalisation préférée de la chaudière de la Fig. 1.The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the description of an exemplary embodiment, said description being made in relation to the accompanying drawings, among which:
Fig. 1 is a schematic view in vertical section of a boiler according to the invention, and
Fig. 2 is an exploded perspective view of a preferred embodiment of the boiler of FIG. 1.
La partie centrale de la chaudière de la Fig. 1 a une allure générale cylindrique à axe vertical et comprend une chambre de combustion 1 en forme de pot formée d'une paroi cylindrique 2 et d'un fond 3, et une chemise annulaire d'eau à chauffer 4 limitée dans le sens radial, d'une part, intérieurement par la face externe de la paroi 2 et, d'autre part, par une enveloppe cylindrique 5. La chemise d'eau 4 est traversée par deux nappes annulaires de tubes verticaux 6 conduisant les gaz de combustion. Les bouts de l'enveloppe cylidrique 5 sont fermés, d'une part, par un fond 7 sous le fond de la chambre de combustion et, d'autre part, par un couvercle 8 en face de la chambre de combustion. The central part of the boiler in FIG. 1 has a generally cylindrical appearance with a vertical axis and comprises a combustion chamber 1 in the form of a pot formed by a cylindrical wall 2 and a bottom 3, and an annular jacket of water to be heated 4 limited in the radial direction, on the one hand, internally by the external face of the wall 2 and, on the other hand, by a cylindrical envelope 5. The water jacket 4 is crossed by two annular layers of vertical tubes 6 leading the combustion gases. The ends of the cylindrical casing 5 are closed, on the one hand, by a bottom 7 under the bottom of the combustion chamber and, on the other hand, by a cover 8 opposite the combustion chamber.
Le centre du couvercle 8 est ouvert pour le passage du brûleur 9 de la chaudière. The center of the cover 8 is open for the passage of the burner 9 of the boiler.
Verticalement, la chemise d'eau 4 est limitée par une couronne circulaire 10 et un fond 11, évidemment percés de trous correspondants aux entrées et sorties des tubes 6. Les tubes 6 sont soudés aux bords des trous des plaques 10 et 11. Vertically, the water jacket 4 is limited by a circular crown 10 and a bottom 11, obviously pierced with holes corresponding to the inlets and outlets of the tubes 6. The tubes 6 are welded to the edges of the holes in the plates 10 and 11.
La face interne du couvercle 8 est doublée d'une couche 12 de matière isolante, telle que des fibres d'alumine. Le bord libre 13 de la paroi 2 se trouve à une certaine distancé de la face interne de la couche isolante 12. La couronne circulaire horizontale 10 a son bord interne soudé au bord libre 13. Entre la couche 12 et la partie externe de la couronne 10, est placée une couronne 14 de matière isolante du même type que la couche 12. Les faces des couches 12 et 14 en regard de la chambre de combustion 1 doivent pouvoir résister aux températures des gaz de combustion très chauds. Autour de la paroi 5, est prévu un revatement isolant 15 en matière adéquate, laquelle n'est pas en contact direct avec les gaz chauds, mais sert à isoler la chemise 4. The internal face of the cover 8 is lined with a layer 12 of insulating material, such as alumina fibers. The free edge 13 of the wall 2 is located at a certain distance from the internal face of the insulating layer 12. The horizontal circular crown 10 has its internal edge welded to the free edge 13. Between the layer 12 and the external part of the crown 10, a crown 14 of insulating material of the same type as the layer 12 is placed. The faces of the layers 12 and 14 facing the combustion chamber 1 must be able to withstand the temperatures of very hot combustion gases. Around the wall 5, an insulating flap 15 is provided in suitable material, which is not in direct contact with the hot gases, but serves to insulate the jacket 4.
Près de la couronne 10, l'enveloppe 5 comporte un orifice sur les bords duquel est soudée une tubulure 16 pour le départ d'eau chaude. Près du fond 11, l'enveloppe 5 comporte un orifice sur les bords duquel est soudée une tubulure 17 servant au retour d'eau froide. Near the crown 10, the casing 5 has an orifice on the edges of which is welded a tube 16 for the departure of hot water. Near the bottom 11, the casing 5 has an orifice on the edges of which is welded a tube 17 serving for the return of cold water.
Entre le fond 3 de la chambre de combustion et le fond 11 de la chemise d'eau, existe un espace également rempli d'eau communiquant avec la chemise. Between the bottom 3 of the combustion chamber and the bottom 11 of the water jacket, there is a space also filled with water communicating with the jacket.
Entre le fond 11 et le fond 7, est prévu un espace relativement haut 18 sur la paroi duquel est prévue une ouverture 19 qui est raccordée au tuyau d'évacuation des fumées. Dans l'espace 18, est monté un échangeur secondaire 20 constitué par un tube bobiné à la façon d'un ressort à boudin, dont une extrémité 21 est raccordée à l'alimentation en eau domestique froide et dont l'autre extrémité 22 est raccordée à l'entrée d'un ballon d'eau chaude sanitaire. Between the bottom 11 and the bottom 7, there is provided a relatively high space 18 on the wall of which is provided an opening 19 which is connected to the smoke evacuation pipe. In the space 18, is mounted a secondary exchanger 20 constituted by a tube wound in the manner of a coil spring, one end of which 21 is connected to the supply of cold domestic water and the other end of which is connected at the entrance to a domestic hot water tank.
A la Fig. 1, on a représenté, au-dessus du fond 7, une nappe 23 d'eau de condensation des gaz de combustion. Une portion de tuyau 24 plongeant dans la nappe 23 permet l'évacuation d'une partie de celle-ci vers ltextérieur. En pratique, le tube 24 traverse horizontalement la paroi 5, à un ou deux centimètres au-dessus du fond 7, et se termine, à l'intérieur, par un coude plongeant dans la nappe 23. In Fig. 1, there is shown, above the bottom 7, a sheet 23 of condensation water of the combustion gases. A portion of pipe 24 plunging into the ply 23 allows the evacuation of a part of it towards the inside. In practice, the tube 24 crosses the wall 5 horizontally, one or two centimeters above the bottom 7, and ends, inside, by a bend plunging into the ply 23.
Dans un exemple préféré de réalisation de l'invention, le tube 20 est une tube flexible onduleux. Un tel tube a une paroi dont la section longitudinale est ondulée, ce qui crée une meilleure surface d'échange entre les gaz chauds sortant de -la chemise d'eau 4 et l'eau domestique. Dans l'exemple montré à la Fig. 1, les spires de la bobine du tube 20 sont jointives, mais on doit comprendre qu'elles ne le sont pas nécessairement. C'est le cas quand le tube 20 est un flexible onduleux. Egalement, à la Fig. 1, on n'a représenté qu'une seule couche de spires, mais il doit être bien entendu que la bobine du tube 20 peut comporter plusieurs couches enroulées les unes par-dessus les autres. In a preferred embodiment of the invention, the tube 20 is a flexible corrugated tube. Such a tube has a wall whose longitudinal section is corrugated, which creates a better exchange surface between the hot gases leaving the water jacket 4 and domestic water. In the example shown in FIG. 1, the turns of the coil of the tube 20 are contiguous, but it should be understood that they are not necessarily so. This is the case when the tube 20 is an undulating hose. Also, in FIG. 1, only one layer of turns has been shown, but it should be understood that the coil of the tube 20 may have several layers wound one on top of the other.
Dans la vue éclatée de la Fig. 2, on reconnaît la paroi externe 5 de la partie centrale cylindrique de la chaudière, au-dessus de laquelle sont successivement montrés la couronne 14 de matière isolante, la couche de matière isolante 12 et un couvercle 39. Les faces externes des éléments 14, 12 et 39 se projettent horizontalement suivant des carrés. Les éléments 12 et 39 présentent chacun une ouverture centrale circulaire pour le passage du col du brûleur. In the exploded view of FIG. 2, the external wall 5 of the central cylindrical part of the boiler is recognized, above which the crown 14 of insulating material, the layer of insulating material 12 and a cover 39 are successively shown. The external faces of the elements 14, 12 and 39 project horizontally along squares. The elements 12 and 39 each have a circular central opening for the passage of the burner neck.
Au-dessous de la partie centrale de la chaudière, sont montrés une bride carrée 25, les parois latérales d'une enceinte 26 et un socle 27, les bords externes de ces éléments se projetant suivant pratiquement le même carré que le couvercle 39. Une fois les éléments assemblés, l'enceinte 26 délimite l'espace relativement haut 18 mentionné plus haut. L'enceinte 26 est pourvue de llouverture rectangulaire 19 sur laquelle se fixe, avec un joint intermédiaire 28, une plaque 29 portant le tuyau d'évacuation des fumées 30. Below the central part of the boiler are shown a square flange 25, the side walls of an enclosure 26 and a base 27, the external edges of these elements projecting in practically the same square as the cover 39. A once the elements have been assembled, the enclosure 26 delimits the relatively high space 18 mentioned above. The enclosure 26 is provided with the rectangular opening 19 on which is fixed, with an intermediate seal 28, a plate 29 carrying the smoke evacuation pipe 30.
L'enceinte est encore pourvue d'une ouverture sur laquelle se monte, avec un joint 31, une plaque 32 portant le tube de débordement 24. The enclosure is also provided with an opening on which is mounted, with a seal 31, a plate 32 carrying the overflow tube 24.
Les parois latérales externes de la chaudière sont constituées par quatre panneaux rectangulaires 33 à 36, dont l'un, 36, est pourvu de découpes pour le passage des tubulures 16 et 17. Ces panneaux sont de préférence en feuille de métal poli. Les arêtes du bloc formé par les panneaux 33 à 36 sont recouvertes de couvre-joints 37. The external side walls of the boiler consist of four rectangular panels 33 to 36, one of which, 36, is provided with cutouts for the passage of the pipes 16 and 17. These panels are preferably made of polished metal sheet. The edges of the block formed by the panels 33 to 36 are covered with joint covers 37.
Enfin on a encore montré un tube de turbulence 38 destiné à être introduit dans un tube de fumées 6. Finally, a turbulence tube 38 has also been shown intended to be introduced into a smoke tube 6.
Il faut noter que l'installation de l'échangeur 20 dans l'enceinte 26 est facultative, bien qu'elle soit recommandée pour améliorer le rendement. It should be noted that the installation of the exchanger 20 in the enclosure 26 is optional, although it is recommended to improve the efficiency.
