Description

La présente invention a pour objet un poêle à combustion.The present invention relates to a combustion stove.

Les poêles à combustion connus sont dotés de deux flux d'air, à savoir un pour l'air qui alimente le foyer et un autre pour l'air qui, en circulant autour de ce foyer, se chauffe et se répand ensuite dans l'ambiance extérieure.Known combustion stoves have two air flows, namely one for the air which feeds the hearth and another for the air which, by circulating around this hearth, heats up and then spreads in the outdoor atmosphere.

Pour améliorer le rendement des poêles, on a adopté différentes solutions telles que l'insertion d'un ventilateur dans le courant d'air pour le chauffage de l'ambiance et surtout la création de courants d'air dans la chambre de combustion, ces courants favorisant la combustion.To improve the efficiency of the stoves, we have adopted different solutions such as the insertion of a fan in the air stream for heating the atmosphere and above all the creation of air currents in the combustion chamber, these currents favoring combustion.

Le but principal de la présente invention est de réaliser un poêle du type ci-dessus décrit dont la combustion donne lieu à une quantité minime de particules imbrûlées et à une présence d'oxyde de carbone très inférieure à celle des dispositifs analogues de type connu, en permettant de la sorte d'obtenir, en plus d'avantages indiscutables sur l'ambiance et sur la santé humaine, un rendement de combustion très élevé.The main object of the present invention is to produce a stove of the type described above, the combustion of which gives rise to a minimal quantity of unburnt particles and to a presence of carbon monoxide much lower than that of similar devices of known type, thus allowing to obtain, in addition to indisputable advantages on the environment and on human health, a very high combustion efficiency.

Le poêle suivant l'invention est défini à la revendication 1.The stove according to the invention is defined in claim 1.

En fait, en même temps que la combustion principale a lieu dans le foyer, on engendre une combustion secondaire dans la partie haute de la chambre ; cette combustion est amorcée par les gaz imbrûlés qui viennent au contact de l'air sous pression à température élevée.In fact, at the same time as the main combustion takes place in the hearth, a secondary combustion is generated in the upper part of the chamber; this combustion is initiated by unburnt gases which come into contact with pressurized air at high temperature.

Le dispositif qui engendre l'air chaud sous pression forme une autre caractéristique originale de l'invention. Ce dispositif est constitué par une chambre placée dans la partie haute du poêle en contact direct avec les fumées de refoulement, laquelle chambre sera par la suite désignée sous le nom de "économiseur".The device which generates hot air under pressure forms another original characteristic of the invention. This device consists of a chamber placed in the upper part of the stove in direct contact with the exhaust fumes, which chamber will subsequently be referred to as the "economizer".

La chambre en question comporte, pour l'admission et pour la sortie de l'air, des ouvertures convenablement dimensionnées afin que cet air ait le temps de se chauffer à l'intérieur de la chambre précitée et puisse, par suite de l'augmentation de son volume, sortir sous une forte pression en favorisant ainsi son mélange complet avec les gaz encore imbrûlés qui tendent à s'élever pour leur évacuation.The chamber in question has, for the admission and the exit of the air, appropriately sized openings so that this air has time to heat up inside the aforementioned chamber and can, as a result of the increase of its volume, exit under a strong pressure thus favoring its complete mixing with the still unburnt gases which tend to rise for their evacuation.

On obtient ainsi une contre-pression de l'air et une oxydation notable de la partie haute de la chambre de combustion, ces deux phénomènes abaissant jusqu'à une valeur minime le pourcentage d'oxyde de carbone présent dans les gaz refoulés dans la cheminée, sans qu'il soit nécessaire d'avoir recours à des injecteurs ou autres systèmes mécaniques de soufflage d'air.This gives a back pressure of the air and a significant oxidation of the upper part of the combustion chamber, these two phenomena lowering to a minimal value the percentage of carbon monoxide present in the gases discharged into the chimney , without the need for injectors or other mechanical air-blowing systems.

En outre, avant de sortir par le conduit d'évacuation, les gaz brûlés sont déviés par une cloison profilée de manière à les obliger à parcourir une trajectoire plus longue, en suscitant ainsi un meilleur transfert de chaleur à l'air chauffé qui est introduit dans l'ambiance et à la chambre qui génère la surpression nécessaire à la combustion secondaire.In addition, before leaving through the exhaust duct, the burnt gases are deflected by a profiled partition so as to force them to travel a longer trajectory, thereby causing better heat transfer to the heated air which is introduced in the atmosphere and in the room which generates the overpressure necessary for secondary combustion.

Une autre originalité de l'invention consiste à faire en sorte qu'au lieu d'être prévu dans la partie initiale du conduit d'évacuation, le volet de réglage des fumées est complètement situé à l'intérieur du corps du poêle et est réglé depuis l'extérieur à l'aide d'un levier.Another originality of the invention consists in ensuring that instead of being provided in the initial part of the exhaust duct, the flue adjustment flap is completely located inside the body of the stove and is adjusted from the outside using a lever.

Enfin, il est avantageusement prévu un nettoyage de la face intérieure du verre transparent en céramique de la chambre de combustion, moyennant création d'une chambre disposée au-dessus de ce verre pour être léchée par les fumées de la combustion, laquelle chambre se réchauffe en engendrant des mouvements de convexion qui aspirent l'air à l'extérieur pour le guider contre la face intérieure précitée.Finally, it is advantageously provided for cleaning the inner face of the transparent ceramic glass of the combustion chamber, by creating a chamber arranged above this glass to be licked by the combustion fumes, which chamber heats up. by generating convection movements which draw the air outside to guide it against the abovementioned inner face.

Ces caractéristiques, ainsi que d'autres encore, vont être maintenant largement illustrées dans la description d'une forme particulière de réalisation, donnée à simple titre d'exemple non limitatif, avec l'aide du dessin annexé dans lequel :

  • La fig. 1 montre le poêle en perspective avec arrachement.
  • La fig. 2 est une coupe verticale de celui-ci.
  • La fig. 3 est une vue de détail de l'économiseur.
These characteristics, as well as others still, will now be widely illustrated in the description of a particular embodiment, given simply by way of nonlimiting example, with the aid of the appended drawing in which:
  • Fig. 1 shows the stove in perspective with cutaway.
  • Fig. 2 is a vertical section thereof.
  • Fig. 3 is a detailed view of the economizer.

Comme montré en fig. 1 et 2, la poêle à combustion comprend, à la façon en soi connue, un corps 1 renfermant la chambre de combustion 2 équipée d'un foyer 3 et d'une porte frontale 4 en verre céramique, une série de conduits d'air qui seront mieux spécifiés plus loin, et un conduit d'évacuation des fumées 5 pourvu d'un volet de réglage 6.As shown in fig. 1 and 2, the combustion stove comprises, in the manner known per se, a body 1 enclosing the combustion chamber 2 equipped a hearth 3 and a front door 4 made of ceramic glass, a series of air ducts which will be better specified below, and a smoke exhaust duct 5 provided with an adjustment flap 6.

Dans la partie principale du poêle à combustion sont prévus deux flux d'air, à savoir celui qui sert à alimenter la combustion et celui qui, circulant dans un espace intermédiaire disposé à l'extérieur de la chambre de combustion, permet à l'air de se chauffer et, par convection, de se répandre dans l'atmosphère ambiante extérieure.In the main part of the combustion stove are provided two air flows, namely that which is used to supply the combustion and that which, circulating in an intermediate space arranged outside the combustion chamber, allows the air to heat up and, by convection, to spread in the outside ambient atmosphere.

Comme cela est bien montré sur le dessin, le flux d'air 7 qui est destiné à alimenter la combustion principale est réglé par une clé 8, tandis que le flux d'air 9 pénètre librement dans la partie inférieure du corps du poêle et, à travers un espace intermédiaire 10, s'élève par convection naturelle ou sous l'effet d'un ventilateur 11 pour sortir vers le haut à travers une grille 12.As is well shown in the drawing, the air flow 7 which is intended to supply the main combustion is regulated by a key 8, while the air flow 9 freely penetrates into the lower part of the stove body and, through an intermediate space 10, rises by natural convection or under the effect of a fan 11 to exit upwards through a grid 12.

La caractéristique essentielle de l'invention réside dans la prévision d'un troisième flux d'air destiné à alimenter le processus de combustion.The essential characteristic of the invention resides in the provision of a third air flow intended to supply the combustion process.

Plus précisément, le flux d'air 13 qui pénètre dans la partie inférieure du poêle à travers un conduit 15, réglé par un volet 14, s'introduit dans une chambre 16, ci-après appelée "économiseur" et positionnée dans la partie supérieure de la chambre de combustion 2.More specifically, the air flow 13 which enters the lower part of the stove through a duct 15, regulated by a flap 14, is introduced into a chamber 16, hereinafter called "economizer" and positioned in the upper part of the combustion chamber 2.

Lorsque la combustion a commencé au niveau du foyer, l'air 17 renfermé dans l'économiseur 16 se chauffe et, en augmentant de volume sort à travers des ouvertures 21 pour générer un flux d'air sous pression 18, à contre-courant par rapport aux fumées de refoulement 19 qui s'élèvent en direction du conduit d'évacuation 5.When the combustion has started at the level of the hearth, the air 17 contained in the economizer 16 heats up and, increasing in volume, leaves through openings 21 to generate a flow of pressurized air 18, against the current by with respect to the discharge fumes 19 which rise in the direction of the exhaust duct 5.

Les mouvements de vortex qui sont ainsi engendrés par la rencontre des deux flux d'air 18 et 19 à contre-courant permettent à l'air à haute température de venir au contact des particules encore imbrûlées retenues dans les fumées de refoulement, en réalisant ainsi une combustion secondaire.The vortex movements which are thus generated by the meeting of the two air flows 18 and 19 against the current allow the high temperature air to come into contact with the still unburnt particles retained in the discharge flue gases, thereby achieving secondary combustion.

Les avantages de cette combustion secondaire sont considérables et portent sur la réduction de l'oxyde de carbone et des particules imbrûlées, en donnant ainsi lieu à une évacuation de fumées plus propres, ainsi qu'à un meilleur rendement de fonctionnement par suite de la température élevée atteinte par cette combustion ultérieure.The advantages of this secondary combustion are considerable and bring on the reduction of carbon monoxide and unburnt particles, thereby giving rise to an evacuation of cleaner fumes, as well as to a better operating efficiency as a result of the high temperature reached by this subsequent combustion.

Afin que l'économiseur 16 fonctionne de manière optimale, il est indispensable de respecter certaines caractéristiques structurelles particulières, bien visibles en fig. 3 ; l'ouie d'entrée 20 pour l'air extérieur doit être large tandis que l'évacuation de l'air à température élevée doit s'effectuer à travers des ouvertures 21 à petit diamètre qui font fonction de buses de soufflage.In order for the economizer 16 to function optimally, it is essential to comply with certain particular structural characteristics, clearly visible in FIG. 3; the inlet port 20 for the outside air must be wide while the evacuation of the air at high temperature must be carried out through small diameter openings 21 which act as blowing nozzles.

Les essais de laboratoire et les calculs thermo-dynamiques ont établi des rapport bien précis entre la puissance du poêle, le volume de l'économiseur 16, la section de l'ouie d'entrée 20 et le débit total de l'air sortant par les ouvertures 21, ces rapports permettant l'obtention d'un fonctionnement dans des conditions de combustion totale.Laboratory tests and thermodynamic calculations have established very precise relationships between the power of the stove, the volume of the economizer 16, the section of the inlet port 20 and the total flow rate of the air leaving the openings 21, these ratios making it possible to obtain operation under conditions of total combustion.

Sur le plan quantitatif, le rapport entre la puissance du foyer exprimée en Kcal/h et le volume de l'économiseur exprimé en cm³ doit être de 1 à 3 ; le rapport entre le volume de l'économiseur, exprimé en cm³, et la surface totale de la section des ouvertures de soufflage, exprimée en cm², doit être de 1 à 220, et le rapport entre la section de l'ouie d'entrée 20 et la section totale des ouvertures de soufflage 21 doit être de 1 à 3.On the quantitative level, the ratio between the power of the hearth expressed in Kcal / h and the volume of the economizer expressed in cm³ must be 1 to 3; the ratio between the volume of the economizer, expressed in cm³, and the total area of the section of the blowing openings, expressed in cm², must be from 1 to 220, and the ratio between the section of the inlet opening 20 and the total section of the blowing openings 21 must be from 1 to 3.

Une autre caractéristique de l'invention porte sur le fait de prévoir une paroi semi-circulaire 22 qui allonge le parcours des fumées de refoulement 19 en direction du conduit 5, ainsi que sur l'insertion du volet 6 pour le réglage desdites fumées à l'intérieur du corps 1 du poêle ce volet étant commandé à l'aide d'une poignée extérieure de manoeuvre 23.Another characteristic of the invention relates to the fact of providing a semi-circular wall 22 which lengthens the path of the discharge fumes 19 in the direction of the duct 5, as well as the insertion of the flap 6 for the adjustment of said fumes to the inside the body 1 of the stove, this shutter being controlled using an external operating handle 23.

L'invention concerne enfin le nettoyage continu de la face intérieure du verre céramique 4 moyennant création d'une chambre 24 prévue au-dessus dudit verre.The invention finally relates to the continuous cleaning of the inner face of the ceramic glass 4 by creating a chamber 24 provided above said glass.

L'air renfermé par cette chambre 24, dont l'entrée est réglée par le moyen d'une clé 25, est chauffé par les fumées de combustion, si bien qu'en augmentant de volume, il sort à travers un orifice 26 pour lécher ainsi la face intérieure de la porte 4 en verre céramique.The air contained by this chamber 24, the inlet of which is regulated by means of a key 25, is heated by the combustion fumes, so that by increasing in volume, it exits through an orifice 26 to thus lick the internal face of the door 4 of ceramic glass.
