Description

La présente invention concerne un procédé permettant de raccorder à un conduit de fumée normal ou conventionnel, une chaudière à gaz du type étanche à tirage forcé et, tout spécialement, une chaudière étanche utilisant un corps du chauffe-échangeur à condensation associé à un brûleur à prémélange d'air et de gaz utilisant un ventilateur sur l'air de combustion.The present invention relates to a method for connecting to a normal or conventional flue, a gas boiler of the sealed type with forced draft and, especially, a sealed boiler using a body of the condensing heat exchanger associated with a burner to air and gas premix using a fan on the combustion air.

On sait qu'une des critiques principales que l'on peut faire à l'encontre du développement de l'installation des chaudières à gaz du type étanche à tirage forcé à travers une microventouse, est l'apparition de panaches de vapeur d'eau sortant plus ou moins perpendiculairement aux façades des immeubles ou maisons par l'orifice d'évacuation des produits de combustion de la microventouse.We know that one of the main criticisms that can be made against the development of the installation of gas boilers of the sealed type with forced draft through a microventacle, is the appearance of plumes of steam leaving more or less perpendicularly to the facades of buildings or houses by the orifice for evacuating the products of combustion from the micro-suction cup.

Ces panaches de vapeur, bien que n'apparaissant que dans certaines conditions de température et d'hygrométrie de l'atmosphère, sont critiqués par les architectes, qui, d'une part craignent que cette vapeur ne provoquent des condensations sur les façades et, partant de là, des risques de dégradation plus ou moins graves, préjudiciables à leur esthétique et, d'autre part, ils craignent aussi que ces jets de vapeur soient critiqués par les utilisateurs eux- mêmes ou leurs voisins immédiats qui pourraient y voir un facteur de pollution.These plumes of vapor, although appearing only under certain conditions of temperature and hygrometry of the atmosphere, are criticized by the architects, who, on the one hand fear that this vapor will cause condensation on the facades and, starting from there, risks of more or less serious degradation, detrimental to their aesthetics and, on the other hand, they also fear that these jets of vapor will be criticized by the users themselves or their immediate neighbors who could see a factor of pollution.

On sait aussi qu'avec le développement des chaudières à gaz du type étanche utilisant un corps de chauffe à condensation, développement hautement souhaitable en raison de l'importante économie d'énergie que l'on peut réaliser avec la généralisation de ce type de chaudière, l'apparition de ces panaches de vapeur interviendra beaucoup plus fréquemment en raison du fait que sur ces chaudières à condensation à très haut rendement, les produits de combustion sortent très souvent à une température voisine ou inférieure à leur température de point de rosée.We also know that with the development of gas boilers of the sealed type using a condensing heating body, a highly desirable development due to the significant energy savings that can be achieved with the generalization of this type of boiler. , the appearance of these steam plumes will occur much more frequently due to the fact that on these very high-efficiency condensing boilers, the combustion products very often exit at a temperature close to or lower than their dew point temperature.

Il serait très dommage que le développement de ces chaudières à condensation à très haut rendement, soit entravé ou freiné par les inconvénients précédemment cités et que l'on ne peut sous estimer.It would be very unfortunate if the development of these very high efficiency condensing boilers was hindered or hampered by the drawbacks mentioned above and which cannot be underestimated.

La présente invention propose un procédé qui permet d'utiliser une cheminée ou un conduit de fumée conventionnel pour à la fois alimenter la chaudière étanche en air de combustion et évacuer les produits de combustion tout en assurant également la collecte et l'évacuation de l'eau pouvant provenir de la condensation de la vapeur d'eau résiduelle contenue dans les produits de combustion.The present invention provides a method which makes it possible to use a conventional chimney or flue for both supplying the sealed boiler with combustion air and evacuating the combustion products while also ensuring the collection and evacuation of the water which may come from the condensation of residual water vapor contained in the products of combustion.

Il est connu d'utiliser deux tubes coaxiaux pour l'évacuation des produits de combustion et l'amenée d'air frais à l'appareil comme décrit dans les brevets US-A 2 619 022, US-A 2 711 683 et GB-A 1 412497, mais il s'agit de tubes rigides conçus en gros-oeuvre au moment de la construction, tandis que l'invention montre un système d'adaptation à une cheminée conventionnelle prévue à l'origine pour la seule évacuation des gaz de combustion.It is known to use two coaxial tubes for the evacuation of combustion products and the supply of fresh air to the appliance as described in patents US-A 2,619,022, US-A 2,711,683 and GB- A 1 412497, but these are rigid tubes designed for structural work at the time of construction, while the invention shows a system for adapting to a conventional chimney originally intended for the sole evacuation of exhaust gases. combustion.

Selon l'invention on raccorde le conduit de cheminée normal ou conventionnel existant dans la construction à la chambre d'admission d'air de la chaudière et on introduit à l'intérieur de ce conduit une tubulure flexible de plus faible diamètre qui elle-même se raccorde à l'orifice d'évacuation des gaz brûlés de l'appareil, et dont l'autre extrémité débouche de la cheminée à l'extérieur du bâtiment.According to the invention, the normal or conventional chimney flue existing in the construction is connected to the air intake chamber of the boiler and a flexible pipe of smaller diameter is introduced inside this flue which itself connects to the burnt gas outlet of the appliance, the other end of which opens out from the chimney outside the building.

Selon une caractéristique complémentaire de l'invention, le raccordement de la tubulure centrale à l'orifice d'évacuation des gaz brûlés de l'appareil est assuré de telle manière que l'eau de condensation ruisselant dans ladite tubulure soit recueillie dans l'appareil avec l'eau de condensation provenant de son échangeur.According to an additional characteristic of the invention, the connection of the central pipe to the orifice for evacuating the burnt gases from the device is ensured in such a way that the condensation water flowing in said pipe is collected in the device. with the condensed water coming from its exchanger.

La description suivante d'un mode de réalisation pris à titre d'exemple non limitatif fera ressortir les avantages de l'invention ainsi que ses autres caractéristiques. On se réfère aux dessins annexés qui représentent:

  • fig.1: une vue schématique générale d'un mode de raccordement d'une chaudière à un conduit de fumée,
  • fig. 2: une vue à plus grande échelle de la sortie de cheminée de la fig. 1,
  • fig. 3: une vue à plus grande échelle du raccordement appareiltubulure dans le cercle de la fig. 1.
The following description of an embodiment taken by way of nonlimiting example will highlight the advantages of the invention as well as its other characteristics. Reference is made to the appended drawings which represent:
  • Fig. 1: a general schematic view of a method of connecting a boiler to a smoke duct,
  • fig. 2: a view on a larger scale of the chimney outlet of FIG. 1,
  • fig. 3: a view on a larger scale of the connection of the tubing device in the circle of FIG. 1.

Une chaudière à condensation désignée dans son ensemble par la référence 1 est disposée dans un local possédant un conduit de cheminée 3 débouchant à l'extérieur de la construction ou de l'immeuble au-dessus du toit 4, par une cheminée proprement dite désignée dans son ensemble par la référence 2.A condensing boiler designated as a whole by the reference 1 is placed in a room having a chimney flue 3 opening to the outside of the construction or of the building above the roof 4, by a chimney proper designated in as a whole by reference 2.

La chaudière du type à condensation comprend essentiellement un brûleur à air soufflé 10 placé à l'intérieur d'un échangeur circulaire 11, un boîtier collecteur des gaz brûlés 12 avec son orifice d'évacuation 13, un tuyau 14 d'évacuation de l'eau de condensation prenant à la base dudit boîtier collecteur et un conduit 15 d'admission du mélange air-gaz au brûleur par l'intermédiaire du ventilateur 18.The condensing type boiler essentially comprises a blast air burner 10 placed inside a circular exchanger 11, a flue gas collecting box 12 with its discharge orifice 13, a pipe 14 for discharging the water of condensation taking up at the base of said collecting box and a duct 15 for admitting the air-gas mixture to the burner by means of the fan 18.

Ce conduit 15 est en liaison avec une chambre 16 d'admission d'air ainsi qu'avec un petit conduit d'arrivée de gaz 17, pour que le mélange s'effectue avant l'arrivée au brûleur.This duct 15 is connected with an air intake chamber 16 as well as with a small gas inlet duct 17, so that the mixing takes place before the arrival at the burner.

La chambre 16 d'admission d'air est raccordée par un manchon 19 au conduit de cheminée 3 existant dans la construction. A l'intérieur de ce conduit 3 est introduit une tubulure flexible 5, - par exemple un tuyau flexible en acier inox -, de plus faible diamètre dont l'extrémité inférieure est raccordée à l'orifice 13 d'évacuation des gaz brûlés de l'appareil, et dont l'extrémité opposée débouche de la cheminée 2 au-dessus du toit. Cette tubulure 5 sert à évacuer les gaz brûlés à l'extérieur tandis que l'air frais nécessaire à la combustion est aspiré de l'extérieur par le conduit 3 lui-même.The air intake chamber 16 is connected by a sleeve 19 to the chimney pipe 3 existing in the construction. Inside this duct 3 is introduced a flexible tube 5, - for example a flexible stainless steel pipe -, of smaller diameter, the lower end of which is connected to the orifice 13 for evacuating the burnt gases from the 'device, and whose opposite end opens from the chimney 2 above the roof. This tubing 5 serves to evacuate the burnt gases outside while the fresh air necessary for the combustion is sucked in from the outside through the pipe 3 itself.

A la partie inférieure, comme le montre la fig. 3, la tubulure 5 se raccorde à l'orifice 13 d'évacuation des gaz brûlés par l'intermédiaire d'une collerette 6 permettant à l'eau de condensation qui ruisselle dans la tubulure de pénétrer dans le boîtier collecteur 12 et d'être évacuée - comme d'ailleurs l'eau de condensation récupérée au niveau de l'échangeur 11 - par le tuyau d'évacuation 14.At the bottom, as shown in fig. 3, the tubing 5 is connected to the orifice 13 for evacuating the burnt gases by means of a collar 6 allowing the condensed water flowing in the tubing to enter the manifold housing 12 and to be evacuated - like, moreover, the condensation water recovered at the exchanger 11 - through the evacuation pipe 14.

A la partie supérieure, comme on le voit plus clairement sur la fig. 2, la tubulure 5 débouche au sommet de la cheminée 2. On scelle sur l'orifice supérieur de cette cheminée un dispositif jouant le rôle d'une microventouse équilibrée pour tous les vents soufflant d'une direction quelconque.At the top, as seen more clearly in fig. 2, the pipe 5 opens at the top of the chimney 2. A device playing the role of a balanced microventacle is sealed on the upper orifice of this chimney for all winds blowing from any direction.

Ce dispositif se présente sous la forme d'une poterie verticale à deux lanternes 20 et 23 dont les orifices supérieurs et inférieurs sont protégés de la pluie jusqu'à une incidence d'au moins 45° par des coiffes 24 et 25. La lanterne supérieure 23 est séparée de la lanterne inférieure 20 par une cloison circulaire horizontale percée en son centre d'un orifice 22 sur lequel vient se raccorder de façon étanche l'extrémité supérieure de la tubulure flexible 5. La lanterne inférieure 20 est munie de lumières latérales 21 d'admission d'air frais vers le conduit de cheminée 3, tandis que la lanterne supérieure 23 possède des lumières latérales 26 pour l'évacuation des gaz de combustion. Dans le conduit de cheminée 3, la disposition de la tubulure 5 est quelconque, c'est-à-dire qu'elle peut présenter des inflexions, suivre le dévoiement de la cheminée, ou même s'appliquer contre un bord du conduit, sans gêner en rien le passage d'air frais puisque le diamètre de la tubulure est notablement inférieur à celui du conduit. De ce fait aucune précaution particulière n'est à prendre au moment de l'introduction de la tubulure dans le conduit ce qui permet par conséquent d'utiliser une tubulure plus ou moins rigide selon la configuration de la cheminée, sans s'inquiéter de la façon dont elle se positionne à l'intérieur. En outre, ce procédé présente encore l'avantage de pouvoir même utiliser un conduit de cheminée en mauvais état puisque son rôle ne sera que de servir de conduit d'amenée d'air et que les éventuels défauts d'étanchéité qu'il peut présenter n'ont pas d'incidence fâcheuse.This device is in the form of a vertical pottery with two lanterns 20 and 23 whose upper and lower orifices are protected from rain to an incidence of at least 45 ° by caps 24 and 25. The upper lantern 23 is separated from the lower lantern 20 by a horizontal circular partition pierced in its center with an orifice 22 to which the upper end of the flexible tube 5 is tightly connected. The lower lantern 20 is provided with lateral lights 21 of fresh air to the chimney 3, while the upper lantern 23 has side lights 26 for the evacuation of combustion gases. In the chimney flue 3, the arrangement of the pipe 5 is arbitrary, that is to say that it can have inflections, follow the deviation of the chimney, or even apply against an edge of the flue, without in no way obstruct the passage of fresh air since the diameter of the tubing is significantly less than that of the duct. Therefore no particular precaution is to be taken at the time of the introduction of the tubing into the duct which therefore allows the use of more or less rigid tubing depending on the configuration of the chimney, without worrying about the the way it is positioned inside. In addition, this method still has the advantage of even being able to use a chimney flue in poor condition since its role will only be to serve as an air supply duct and as any leaks it may have have no untoward impact.

Enfin, grâce à la collerette 6, toute l'eau de condensation de la tubulure est récupérée dans l'appareil, et rejoint l'eau provenant de l'échangeur lui-même.Finally, thanks to the collar 6, all the condensation water from the tubing is recovered in the device, and joins the water coming from the exchanger itself.
