Description

L'invention concerne une grille pour la combustion de toutes sortes de combustibles solides dans des poêles, des foyers, des chaudières de chauffage central, des fours, des fours à combustion, des séchoirs et autres, bref, une grille pour la combustion de combustibles solides dans des espaces fermés et ouverts.The invention relates to a grid for the combustion of all kinds of solid fuels in stoves, fireplaces, central heating boilers, ovens, combustion ovens, dryers and the like, in short, a grid for the combustion of fuels solid in closed and open spaces.

Le but principal de l'invention est la réalisation d'une grille qui permet un réglage parfait du feu avec une très haute température de combustion et un grand rendement, et ce quelle que soit l'espèce de combustible solide utilisé.The main object of the invention is the production of a grid which allows perfect adjustment of the fire with a very high combustion temperature and a high yield, regardless of the species of solid fuel used.

Un autre but consiste en ce que le verre à l'épreuve du feu qui se trouve dans une porte pour la fermeture par exemple d'un foyer ou d'une poële soit maintenu libre de suie, de goudron et de condensation. Encore un autre but consiste en la réalisation d'une grille de longue durée de vie.Another object is that the fireproof glass which is in a door for closing, for example, a fireplace or a stove is kept free of soot, tar and condensation. Yet another goal is to achieve a long life grid.

Connues sont les grilles que peuvent traverser, à la capacité maximale de l'appareil de combustion, la quantité totale d'air primaire et pratiquement également tout l'air secondaire. Un inconvénient de ces grilles est toutefois qu'elles laissent passer le plus d'air là où il y a le moins de résistance, en d'autres termes, aux endroits où le moins de combustible est présent et où le feu est le moins vif. Dans ce cas, l'air superflu ou en excédent est partiellement utilisé en tant qu'air secondaire, qui influe en grande partie sur le côté extérieur des flammes, ce qui donne lieu à une combustion mauvaise et trop rapide du combustible et à une évacuation trop rapide des gaz de fumée chauds vers la cheminée. Un rendement mauvais ou inefficace est alors le résultat de tels appareils de combustion.Known are the grids that can pass, at the maximum capacity of the combustion device, the quantity total primary air and almost all secondary air as well. A disadvantage of these grates, however, is that they let in the most air where there is the least resistance, in other words, in the places where the least fuel is present and where the fire is the least lively . In this case, excess or surplus air is partially used as secondary air, which largely influences the outside of the flames, resulting in poor and too rapid combustion of the fuel and evacuation. hot smoke gases to the chimney too fast. Poor or ineffective efficiency is then the result of such combustion devices.

Si l'appareil de combustion est pourvu d'une paroi ou porte en verre, il vient s'y ajouter l'inconvénient que le verre est très vite souillé de suie, de goudron et de produit de condensation, par suite de quoi le verre devient non transparent et la chaleur de rayonnement, qui est très grande au verre, diminue sensiblement. En outre, dans beaucoup de cas, le verre est surchauffé à cette occasion, de sorte que l'incrustation sur le verre y est cuite avec pour conséquence que le feu n'est plus visible qu'à peine ou plus du tout.If the combustion appliance is provided with a glass wall or door, there is the disadvantage that the glass is very quickly soiled with soot, tar and condensate, as a result of which the glass becomes non-transparent and the radiant heat, which is very large on glass, decreases appreciably. In addition, in many cases, the glass is overheated on this occasion, so that the encrustation on the glass is cooked there with the consequence that the fire is hardly visible any more than hardly or at all.

Pour y remédier, la grille se compose selon la caractéristique principale de l'invention de deux grilles placée l'une au-dessus et contre l'autre, qui sont déplaçables l'une par rapport à l'autre et auxquelles le passage de chaque ouverture de passage formée dans une des grilles est plus grand au centre de cette grille afin, lors du déplacement d'une des grilles précitées, de fermer les ouvertures de passage de l'autre grille graduellement à partir de ses extrémités.To remedy this, the grid is composed according to the main characteristic of the invention of two grids placed one above and against the other, which are movable relative to each other and to which the passage of each passage opening formed in one of the grids is larger in the center of this grid so, when moving one of the above grids, to close the passage openings of the other grid gradually from its ends.

De ce fait, seul de l'air primaire passe par la grille en fonction de la quantité d'air nécessaire au centre et aux côtés extérieurs du feu. Le centre du feu peut donc recevoir plus d'air que ses côtés extérieurs, et ce selon la position des grilles l'une par rapport à l'autre. L'amenée d'air primaire est donc réglable, de sorte que le débit d'air peut être graduellement réduit vers les extrémités des ouvertures de passage dans la grille en fermant graduellement ces extrémités, et en même temps une plus grande quantité d'air peut être amenée vers le centre du feu. Un avantage secondaire de ceci est que 1à ou il y a le plus de feu sur la grille, celle-ci est refroidie le plus à cet endroit, par suite de quoi la durée de vie de la grille est considérablement allongée.Therefore, only primary air passes through the grid depending on the amount of air required at the center and at exterior sides of the light. The center of the fire can therefore receive more air than its outer sides, and this depending on the position of the grids relative to each other. The primary air supply is therefore adjustable, so that the air flow can be gradually reduced towards the ends of the passage openings in the grid by gradually closing these ends, and at the same time a greater quantity of air. can be brought to the center of the fire. A secondary advantage of this is that 1a where there is the most fire on the grid, it is cooled the most there, as a result of which the life of the grid is considerably extended.

En amenant, en cas d'utilisation d'une porte ou d'une paroi en verre dans l'appareil de combustion, de l'air secondaire par une ouverture aménagée dans la chambre de combustion sous la porte et en conduisant cet air verticalement à travers ladite chambre de combustion, on forme un rideau d'air parfaitement pur avec ± 20 % d'oxygène pur devant la porte ou paroi en verre, grâce à quoi celle-ci reste impeccablement propre. Un autre avantage de l'installation décrite ci-dessus est que la pollution de l'air par le monoxyde de carbonne est réduite et que le volume des cendres est réduit à un minimum/By supplying, if a door or a glass wall is used in the combustion appliance, secondary air through an opening in the combustion chamber under the door and by conveying this air vertically to through said combustion chamber, a curtain of perfectly pure air is formed with ± 20% of pure oxygen in front of the door or glass wall, thanks to which the latter remains impeccably clean. Another advantage of the installation described above is that the air pollution by carbon monoxide is reduced and that the volume of ash is reduced to a minimum /

A titre d'exemple sans aucun caractère limitatif, il suit ci-dessous une description plus détaillée d'une forme de réalisation de la grille choisie en conformité avec l'invention, appliquée & un foyer ouvert. Cette description renvoie aux dessins annexés, dans lesquels

  • la fig. 1 représente une coupe transversale d'un foyer ouvert à clapet économisant et porte en verre;
  • la fig. 2 représente la grille supérieure fixe en perspective;
  • la fig. 3 représente la grille inférieure déplaçable en perspective;
  • la fig. 4 représente une vue d'en haut des deux grilles placées l'une au-dessus de l'autre dans une plaque fixe; la fig. 5 représente une coupe longitudinale suivant la ligne V-V de la fig. 4;
  • la fig. 6 représente une vue d'en haut des deux grilles placées l'une au-dessus de l'autre dans la plaque fixe, mais la grille déplaçable étant partiellement déplacée.
By way of example without any limiting character, below follows a more detailed description of an embodiment of the grid chosen in accordance with the invention, applied to an open hearth. This description refers to the accompanying drawings, in which
  • fig. 1 shows a cross section of an open hearth with saving valve and glass door;
  • fig. 2 shows the fixed upper grid in perspective;
  • fig. 3 shows the lower grid movable in perspective;
  • fig. 4 shows a view from above of the two grids placed one above the other in a fixed plate; fig. 5 shows a longitudinal section along the line VV of FIG. 4;
  • fig. 6 shows a view from above of the two grids placed one above the other in the fixed plate, but the movable grid being partially displaced.

Dans ces figures, on remarque le foyer ouvert 1 à clapet économisant 2, qui est fermé par une porte en verre 3. En bas dans le foyer ouvert 1, une grille fixe 5 est placée dans une plaque fixe 4 et est pourvue d'ouvertures de passage 6 oblongues à bords longitudinaux parallèles. Sous et contre cette grille, il y a une deuxième grille 7 de la même dimension que la grille 5, suspendue d'une manière déplaçable dans deux profilés guides 8-9, qui sont fixés au côté inférieur de la plaque 4. Dans cette deuxième grille 7 sont également prévues des ouvertures de passage 10 oblongues, mais dont chaque fois un des bords longitudinaux a la forme d'un V obtus, de sorte que chaque ouverture de passage est le plus large dans sa partie centrale et est plus large que la distance entre les bords longitudinaux des ouvertures de passage 6 de la première grille 5. Ces ouvertures de passage 6-10 dans les deux grilles 5-7 devraient aussi pouvoir avoir d'autres formes et peuvent se trouver sous la forme de petits trous, ouvertures ovales, rondes ou sous d'autres formes, placés en triangle, à condition qu'il soit veillé à ce que le passage de chaque ouverture de passage 10 formée dans la grille 7 soit plus grande au centre de cette grille. C'est ainsi que cette grille pourrait être pourvue au centre d'ouvertures qui sont plus grandes que celles prévues près des côtés latéraux de la grille, ou bien on pourrait prévoir au centre de la grille plus d'ouvertures que près des bords latéraux de celle-ci. Cette grille 7 est pourvue au devant d'une manette 11, qu'on peut actionner sur le devant du foyer ouvert pour déplacer ladite grille 7 par rapport à la grille 5. Le passage de l'air est maximal quand les ouvertures de passage 6-10 des deux grilles 5-7 sont juste superposées. Mais quand la grille inférieure 7 est déplacée jusqu'à ce que les ouvertures de passage 6 de la grille 5 sont fermées, l'air ne peut plus passer. La grille 7 peut aussi être déplacée partiellement dans les profilés de guidage 8-9 jusqu'à ce que les extrémités des ouvertures de passage 6 de la grille 5 sont fermées et que seule la partie centrale en reste libre. Dans ce cas, chaque ouverture de passage a la forme d'un triangle. La partie centrale de la grille reçoit alors plus d'air que ses côtés latéraux, de sorte que la combustion du combustible sur la grille est le plus vive au centre du combustible. Un réglage efficace de l'air est donc possible en fonction de la taille du feu qu'on désire obtenir. Sous la porte en verre 3, de préférence une ouverture oblongue 12 est prévue pour laisser pénétrer de l'air secondaire dans la chambre de combustion 13, et dans cette chambre de combustion 13, un profilé 14 guidant l'air est placé devant ladite ouverture pour faire dévier l'air verticalement contre le côté intérieur de la porte en verre 3, où les gaz non brûlés sont mélangés dans la chambre de combustion 13 à l'air secondaire fraîchement amené. De ce fait, un rideau d'air parfaitement pur avec ± 20 % d'oxygène pur est formé contre la porte en verre 3, grâce à quoi celle-ci reste impeccablement propre.In these figures, we note the open hearth 1 with a saving valve 2, which is closed by a glass door 3. Below in the open hearth 1, a fixed grid 5 is placed in a fixed plate 4 and is provided with openings 6 oblong passageways with parallel longitudinal edges. Under and against this grid, there is a second grid 7 of the same dimension as the grid 5, suspended in a movable manner in two guide sections 8-9, which are fixed to the lower side of the plate 4. In this second grid 7 are also provided with oblong passage openings 10, but each of which one of the longitudinal edges has the shape of an obtuse V, so that each passage opening is the widest in its central part and is wider than the distance between the longitudinal edges of the passage openings 6 of the first grid 5. These passage openings 6-10 in the two grids 5-7 should also be able to have other shapes and may be in the form of small holes, openings oval, round or in other forms, placed in a triangle, provided that care is taken to ensure that the passage of each passage opening 10 formed in the grid 7 is greater in the center of this grid. Thus this grid could be provided in the center with openings which are larger than those provided near the lateral sides of the grid, or else one could provide in the center of the grid with more openings than near the lateral edges of this one. This grid 7 is provided at the front with a lever 11, which can be actuated on the front of the open hearth to move said grid 7 relative to the grid 5. The passage of air is maximum when the passage openings 6-10 of the two grids 5-7 are just superimposed. But when the lower grid 7 is moved until the passage openings 6 of the grid 5 are closed, the air can no longer pass. The grid 7 can also be partially displaced in the guide profiles 8-9 until the ends of the passage openings 6 of the grid 5 are closed and only the central part remains free. In this case, each passage opening has the shape of a triangle. The central part of the grate then receives more air than its lateral sides, so that the combustion of the fuel on the grate is most intense in the center of the fuel. An effective air regulation is therefore possible depending on the size of the fire you want to obtain. Under the glass door 3, preferably an oblong opening 12 is provided to allow secondary air to enter the combustion chamber 13, and in this combustion chamber 13, a profile 14 guiding the air is placed in front of said opening. to deflect the air vertically against the inner side of the glass door 3, where the unburned gases are mixed in the combustion chamber 13 with the freshly supplied secondary air. As a result, a perfectly pure air curtain with ± 20% pure oxygen is formed against the glass door 3, thanks to which the latter remains impeccably clean.

Il va de soi que la forme et les dimensions des parties décrites ci-dessus ainsi que leur position mutuelle peuvent différer et qu'également quelques-unes des parties décrites ci-dessus pourraient être remplacées par d'autres qui visent le même but, tout en restant dans le cadre de l'invention.It goes without saying that the shape and dimensions of the parts described above as well as their mutual position may differ and that also some of the parts described above could be replaced by others which aim at the same goal, whatever remaining within the scope of the invention.
