Des chaudières à condensation sont connues. Leur intérêt réside dans le fait d' .être susceptibles de récupérer la chaleur de condensation des fumées et gaz de combustion en provoquant la condensation dans un échangeur - condenseur et récupérer ainsi une masse calorifique normalement rejetée pour la transmettre à l'eau du circuit de chauffage.Condensing boilers are known. Their interest lies in the fact of being capable of recovering the heat of condensation of smoke and combustion gases by causing condensation in an exchanger-condenser and thus recovering a calorific mass normally rejected for transmitting it to the water of the circuit of heater.
Le but de l'invention est de conférer à une telle chaudière à condensation les avantages et perfectionnements complémentaires ci-après spécifiés :The object of the invention is to confer on such a condensing boiler the additional advantages and improvements specified below:
1°) Parfaire la récupération des calories contenues dans les gaz de combustion.1 °) Perfect the recovery of calories contained in the combustion gases.
2°) Réduire les coûts de fabrication de la chaudière à condensation, l'échangeur - condenseur y inséré étant issu d'un corps de chauffe de chaudière de plus faible puissance de chauffe, produit en série industrielle dans la même matière constitutive que celui-ci et donc à moindre prix de revient.2 °) Reduce the manufacturing costs of the condensing boiler, the exchanger - condenser inserted therein coming from a boiler heating body of lower heating power, produced in industrial series in the same constituent material as that- here and therefore at a lower cost price.
D'où une appréciable économie de réalisation de cette chaudière de type industriel.Hence an appreciable saving in the production of this industrial type boiler.
3°) Rendre l'échangeur - condenseur, de par sa caractéristique modulaire, facilement interchangeable et transformable puisque, en plus, de provenance de série, d'une production non spéciale.3 °) Make the exchanger - condenser, by its modular characteristic, easily interchangeable and transformable since, in addition, from series production, from non-special production.
4°) Permettre à la chaudière a condensation, de type industriel, de fonctionner avec une sécurité de service nettement accrue, l'adjonction d'un circuit en by-pass, disposé en parallèle avec celui de l'échangeur - condenseur, assurant la continuitéde fonctionnement de l'installation de chauffage en cas .le mise hors service de l'échangeur - condenseur au moyen .le l'ouverture de la dérivation durant la période de son non Ionetionnoment.4 °) Allow the condensing boiler, of industrial type, to operate with a clearly increased service safety, the addition of a by-pass circuit, arranged in parallel with that of the exchanger - condenser, ensuring the continuity of operation of the heating system in the event .the deactivation of the exchanger - condenser by means of .the opening of the bypass during the period of its non-ionisation.
5º) En cas d'urgence, la chaudière peut fonctionner sans échangeur - condenseur. Elle- serait en panne d'économie simplement mais non en arrêt complet.5º) In an emergency, the boiler can operate without exchanger - condenser. It would simply be out of economy but not completely stopped.
La lecture de la description suivante, effectuée à titre d'exemple non limitatif et illustrée à l'aide des dessins ci-annexés de l'installation de chauffage avec chaudière modulaire a condensation, conforme à l'invention, permettra de la comprendre aisément.Reading the following description, given by way of nonlimiting example and illustrated with the accompanying drawings of the heating installation with modular condensing boiler, in accordance with the invention, will make it easy to understand it.
Dans les dessins annexés : la figure 1 représente schématiquement la chaudière a condensation vue en coupe. La figure 2 est le schéma il lustrât if des raccordements et des circuits entre le corps de chauffe, l'échangeur - condenseur et les radiateurs.In the accompanying drawings: Figure 1 schematically shows the condensing boiler seen in section. Figure 2 is the schematic diagram of the connections and circuits between the heating body, the exchanger - condenser and the radiators.
En se référant à la figure 1 représentant schématiquement une exécution possible de la chaudière à condensation selon l'invention, on reconnaît le corps de chauffe 1, réalisé de préférence en fonte, un foyer 2 , de type conventionnel, équipé d'un brûleur à gaz 3, du type atmosphérique, avec rampe 4 ou à air soufflé.Referring to Figure 1 schematically showing a possible embodiment of the condensation boiler according to the invention, we recognize the heating body 1, preferably made of cast iron, a hearth 2, of conventional type, equipped with a burner gas 3, of the atmospheric type, with rail 4 or with supply air.
Les fumées et gaz de combustion sont dirigés par un renvoi vers un échangeur - condenseur 5 en fonte. Le fond de ce compartiment intermédiaire 6 sert de bac de récupération 7 des condensats avec évacuation au réseau d'assainissement. Ce fond communique avec une collecte 8 prévue sur ie support de l'échangeur - condenseur 5. Ce dernier, réalisé en fonte, est un corps de chauffe de chaudières existantes, de puissance de chauffe inférieure, produites également en grande série.The smoke and combustion gases are directed by a return to a heat exchanger - condenser 5 in cast iron. The bottom of this intermediate compartment 6 serves as a condensate recovery tank 7 with evacuation to the sewerage network. This bottom communicates with a collection 8 provided on the support of the exchanger - condenser 5. The latter, made of cast iron, is a heating body of existing boilers, of lower heating power, also produced in large series.
Les fumées sont dirigées et asnirées dans un compartiment supérieur 9 équipé d'un groupe d'extraction 10 pour être évacuées, à faible température, éventuellement après déshydratation, à travers un conduit de fumées 11 puis une cheminée gainée 12. On décrira maintenant le schéma des circuits en se référant à la figure 2.The fumes are directed and sucked into an upper compartment 9 equipped with an extraction group 10 to be evacuated, at low temperature, possibly after dehydration, through a flue pipe 11 then a sheathed chimney 12. We will now describe the circuit diagram with reference to Figure 2.
Le corps de chauffe 1 possède une boucle vie circulation extérieure 14 assurée par la pompe 15 qui permet de répartir uniformément la température dans son voIlume intérieur.The heating body 1 has an external circulation life loop 14 provided by the pump 15 which makes it possible to uniformly distribute the temperature in its internal volume.
Sur cette boucle de circulation extérieure se greffe le circuit 16 de l'installation qui comprendOn this external circulation loop is grafted the circuit 16 of the installation which includes
I'échangeur-condenseur 5 monté en série dans le trajet retour de l'eau des radiateurs 13 en vue de son préchauffage.The heat exchanger-condenser 5 mounted in series in the return path of the water from the radiators 13 for preheating.
Ce circuit, monté de part et d'autre de la pompe 15, comprend une vanne mélangeuse 17 à trois voies, un circulateur 18, les radiateurs 13 et I'échangeur- condenseur 5 court-circuité par une dérivation 19 avec vanne de sectionnement 20.This circuit, mounted on either side of the pump 15, comprises a three-way mixing valve 17, a circulator 18, the radiators 13 and the exchanger-condenser 5 short-circuited by a bypass 19 with sectioning valve 20 .
La branche comprenant l'échangeur 5 possède deux vannes d'isolement 21 et 22 permettant sa mise hors service et son remplacement sans arrêter le fonctionnement de l'installation en raison de la branche de dérivation 19.The branch comprising the exchanger 5 has two isolation valves 21 and 22 allowing it to be taken out of service and replaced without stopping the operation of the installation due to the branch branch 19.
Cette disposition permet aussi, pour des causes et raisons diverses, dé faire fonctionner l'installa- tion sans échangeur. On se trouve alors en panne d'économie mais non de fonctionnement. Outre ces avantages, cette disposition ou cet aménagement du circuit hydraulique permet un bon dégazage de l'eau de chauffage.This arrangement also makes it possible, for various reasons and reasons, to operate the installation without an exchanger. We are then out of economy but not functioning. In addition to these advantages, this arrangement or arrangement of the hydraulic circuit allows good degassing of the heating water.
L'invention a été décrite à propos d'une réalisation particulière. Il est bien entendu, toutefois, que diverses modifications simples, substitutions par des moyens équivalents et autres variantes directes ne sauraient échapper à la présente protection. The invention has been described in connection with a particular embodiment. It is understood, however, that various simple modifications, substitutions by equivalent means and other direct variants cannot escape this protection.
