Abstract
Description
L'invention concerne une chaudière pour la combustion de combustibles liquides ou gazeux, constituée par un carter de circulation d'eau dans lequel est disposée une chambre de combustion ayant un fond éloigné du brûleur, et à partir duquel plusieurs carneaux de gaz chauds, disposés parallèlement entreeux et formant un bloc de carneaux, conduisent à une chambre de collecte des gaz de fumées, le dimensionnement et la disposition du bloc de carneaux étant fixés pour un fonctionnement en chaudière à condensation. The invention relates to a boiler for the combustion of liquid or gaseous fuels, constituted by a water circulation casing in which is disposed a combustion chamber having a bottom remote from the burner, and from which several hot gas flues, arranged parallel to each other and forming a block of flues, lead to a flue gas collection chamber, the dimensioning and arrangement of the block of flues being fixed for operation in a condensing boiler.
De telles chaudières sont suffisamment connues, de sorte qu'elles ne nécessitent pas d'autres références particulières à des documents. Par le dimensionnement et la disposition des carneaux de gaz chauds pour un fonctionnement en chaudière à condensation, il faut ici comprendre d'une part que les carneaux de gaz chauds, en raison de la grandeur de leur surface d'échange de chaleur, conduisent intentionnellement à une condensation des gaz chauds qui les traversent, la disposition des carneaux étant d'autre part réalisée de manière que le condensat qui se forme puisse s'écouler. Such boilers are sufficiently known, so that they do not require other particular references to documents. By the dimensioning and the arrangement of the hot gas flues for operation in a condensing boiler, it should be understood here on the one hand that the hot gas flues, due to the size of their heat exchange surface, intentionally lead to a condensation of the hot gases passing through them, the arrangement of the flues being on the other hand carried out so that the condensate which forms can flow.
Si une telle chaudière doit fonctionner d'une autre manière, c'est à dire selon un mode normal sans formation de condensat, le fabricant de chaudière est contraint de fabriquer une chaudière correspondante différente, et tout au moins de réaliser différemment les carneaux, à savoir le bloc de carneaux. If such a boiler is to operate in another way, that is to say in a normal mode without the formation of condensate, the boiler manufacturer is forced to manufacture a different corresponding boiler, and at least to produce the flues differently, know the block of flues.
Aussi, le but de l'invention consiste, par des mesures simples, à transformer une telle chaudière qui en soi est conçue pour un fonctionnement en chaudière à condensation, de façon à ce quelle puisse également fonctionner de manière normale, sans formation de condensat, avec un rendement élevé et une température des gaz de fumées sensiblement plus élevée. Also, the object of the invention consists, by simple measures, in transforming such a boiler which in itself is designed for operation as a condensing boiler, so that it can also operate normally, without formation of condensate, with a high efficiency and a significantly higher flue gas temperature.
Conformément à l'invention, ce but est atteint pour une chaudière du type de celle mentionnée en introduction, par le fait que la surface du fond de la chambre de combustion est d'une dimension supérieure à la surface de raccordement d'entrée du bloc de carneaux, et qutà l'extérieur du bloc de carneaux, entre la partie en saillie du fond de la chambre de combustion et la paroi de raccordement de la chambre de collecte des gaz de fumées, est disposé au moins un parcours de gaz chauds supplémentaire dans l'ouverture d'entrée duquel est disposé de manière amovible, un bouchon d'obturation. According to the invention, this object is achieved for a boiler of the type mentioned in the introduction, by the fact that the surface of the bottom of the combustion chamber is of a dimension greater than the inlet connection surface of the block. at least one additional hot gas path is arranged outside the flue block between the projecting part of the bottom of the combustion chamber and the connecting wall of the flue gas collection chamber in the inlet opening of which is removably disposed, a closure plug.
Pour le fabricant, l'investissement légèrement plus important nécessité par la fabrication d'une telle chaudière, est sans commune mesure avec l'investissement qui était à effectuer lorsque le fabricant devait fabriquer pour chacun des deux modes de fonctionnement cités, une chaudière correspondante adaptée. For the manufacturer, the slightly larger investment required by the manufacture of such a boiler is incomparable with the investment which had to be made when the manufacturer had to manufacture for each of the two operating modes mentioned, a corresponding suitable boiler. .
Dans le cas d'un fonctionnement en chaudière à condensation, les parcours de gaz chauds prévus en supplément, disposés au-dessus et/ou à côté du bloc de carneaux, et se présentant de préférence sous la forme de simples tubes, sont fermés par des bouchons d'obturation pouvant être retirés, et dans le cas où les bouchons d'obturation n'existent pas ou n'ont pas été mis en place, on obtient le mode de fonctionnement normal pour une chaudière dans laquelle la température des gaz de fumées est sensiblement plus élevée que dans le cas d'une chaudière à condensation. In the case of an operation in a condensing boiler, the hot gas paths provided in addition, arranged above and / or next to the flue block, and preferably in the form of simple tubes, are closed by blanking plugs which can be removed, and in the case where blanking plugs do not exist or have not been fitted, the normal operating mode is obtained for a boiler in which the temperature of the smoke is significantly higher than in the case of a condensing boiler.
Dans la suite, la chaudière conforme à l'invention, va être explicitée plus en détail, au regard d'un exemple de réalisation représenté de manière schématique sur les dessins annexés qui montrent:
Fig. 1 : une coupe longitudinale de la chaudière le long de la ligne I-I de la figure 2, et
Fig. 2 : une coupe le long de la ligne II-II de la chaudière selon la figure 1.In the following, the boiler according to the invention will be explained in more detail, with regard to an embodiment shown schematically in the accompanying drawings which show:
Fig. 1: a longitudinal section of the boiler along line II of FIG. 2, and
Fig. 2: a section along line II-II of the boiler according to FIG. 1.
Comme le montre la figure 1, la chaudière est constituée par un carter de circulation d'eau 1 dans lequel est disposée une chambre de combustion 2 dont le fond 3 est éloigné du brûleur. A partir du fond 3, plusieurs carneaux de gaz chauds 4 disposés parallèlement entre-eux et formant un bloc de carneaux 4', conduisent à une chambre de collecte des gaz de fumées 5, le dimensionnement et la disposition des carneaux de gaz chauds étant fixés pour un fonctionnement en chaudière à condensation. As shown in FIG. 1, the boiler consists of a water circulation casing 1 in which a combustion chamber 2 is arranged, the bottom 3 of which is remote from the burner. From the bottom 3, several hot gas flues 4 arranged parallel to each other and forming a block of flues 4 ', lead to a flue gas collection chamber 5, the dimensioning and arrangement of the hot gas flues being fixed for operation in a condensing boiler.
La configuration particulière, représentée à titre d'exemple, des carneaux de gaz chauds qui sont conçus dans l'optique d'un fonctionnement en chaudière à condensation, ne nécessite pas dans ce cas, d'explications particulières; on remarquera simplement que la disposition inclinée des ondulations de parois 9 des carneaux et l'inclinaison des carneaux sont prévues de manière telle que le condensat puisse s'écouler, à savoir vers la chambre de collecte des gaz de fumées 5 et/ou vers la chambre de combustion 2, qui dans ce cas doit alors être pourvue d'une conduite de condensat 10 menant à la chambre de collecte des gaz de fumées 5, tel que cela est représenté. The particular configuration, shown by way of example, of the hot gas flues which are designed with a view to operating in a condensing boiler, does not require in this case, particular explanations; it will simply be noted that the inclined arrangement of the wall corrugations 9 of the flues and the inclination of the flues are provided in such a way that the condensate can flow, namely towards the flue gas collection chamber 5 and / or towards the combustion chamber 2, which in this case must then be provided with a condensate line 10 leading to the smoke gas collection chamber 5, as shown.
Pour une chaudière d'une telle configuration, il est à présent essentiel que la surface (F) du fond 3 de la chambre de combustion soit d'une dimension supérieure à la surface de raccordement (F1) d'entrée, à savoir la surface amont du bloc de carneaux 4' formés par tous les carneaux 4, et qu'à l'extérieur du bloc de carneaux 4', entre le fond 3 de la chambre de combustion et la chambre de collecte des gaz de fumées 5, soit disposé au moins un parcours de gaz chauds supplémentaire 6 de forme tubulaire, dans l'ouverture d'entrée 7 duquel est disposé de manière amovible, un bouchon d'obturation 8. For a boiler of such a configuration, it is now essential that the surface (F) of the bottom 3 of the combustion chamber is of a dimension greater than the connecting connection surface (F1), namely the surface upstream of the flue block 4 'formed by all the flues 4, and that outside the flue block 4', between the bottom 3 of the combustion chamber and the flue gas collection chamber 5, is disposed at least one additional hot gas path 6 of tubular shape, in the inlet opening 7 of which is removably disposed, a closure plug 8.
Dans l'exemple de réalisation, la chaudière est équipée de trois parcours de gaz chauds supplémentaires 6 de forme tubulaire (voir figure 2), qui s'étendent entre la partie en saillie 11 du fond de la chambre de combustion et la paroi de raccordement de la chambre de collecte des gaz de fumées 5. Les bouchons d'obturation 8 réalisés en un matériau réfractaire, sont logés, en étant de dimension appropriée, dans les ouvertures d'entrée 7 de ces parcours de gaz chauds 6, seuls les carneaux de gaz chauds 4 étant alimentés en gaz chauds lors du fonctionnement en chaudière à condensation. In the exemplary embodiment, the boiler is equipped with three additional hot gas paths 6 of tubular shape (see FIG. 2), which extend between the projecting part 11 of the bottom of the combustion chamber and the connection wall of the smoke gas collection chamber 5. The closure plugs 8 made of a refractory material, are housed, being of appropriate size, in the inlet openings 7 of these hot gas paths 6, only the flues of hot gases 4 being supplied with hot gases during operation in a condensing boiler.
