REGLABLEADJUSTABLE
La présente invention concerne les récupérateurs de calories pour le feu de bois dans les cheminées à foyer ouvert utilisant les fluides caloporteurs.The present invention relates to heat recuperators for wood fires in open fireplaces using heat transfer fluids.
Le problème technique posé est celui de récupérer et de restituer de façon optimale l'énergie dégagée par un feu de bois dans une cheminée à foyer ouvert tout en préservant l'esthétique et les caractéristiques de la cheminée.The technical problem posed is that of optimally recovering and restoring the energy released by a wood fire in an open hearth fireplace while preserving the aesthetics and characteristics of the fireplace.
Actuellement, la majeure partie de ces calories se perd dans la nature ou e^t médiocrement récupérée par des récupérateurs d'énergie qui offrent de mauvais rendements liés à une esthétique très contecstable.Currently, most of these calories are lost in nature or are poorly recovered by energy recuperators which offer poor yields linked to a very contecstable aesthetic.
Le problème du rendement médiocre des récupérateurs de chaleur est dû à leur mauvaise position par rapport à la source de chaleur, position liée à des considérations esthétiques. De plus, statiques, ils ne tiennent pas compte de l'évolution du feu.The problem of the poor performance of heat recovery units is due to their poor position in relation to the heat source, a position linked to aesthetic considerations. In addition, static, they do not take into account the evolution of the fire.
La position idéale se situe au dessus et au plus près du feu d'âtre de la cheminée, dans la partie la plus apparente nu fayer.The ideal position is located above and as close as possible to the hearth fire in the fireplace, in the most visible part of the fireplace.
Une approche dans ce sens a été présentée dans le brevet N° 2484 613 qui propose un dispositif de chaudron destiné au chauffage central. Cependant, celui-ci n'offre pas de caractéristique novatrice réelle et le manque de performances est évident car, un chaudron ne peut en aucune façon obtenir le rendement d'une chaudière, d'autant plus qu'il est statique.An approach in this direction has been presented in patent N ° 2484 613 which proposes a cauldron device intended for central heating. However, it does not offer any real innovative characteristic and the lack of performance is obvious because, a cauldron cannot in any way obtain the performance of a boiler, especially since it is static.
Les caractéristiques des revendications concernant ce brevet sont les suivantes :The features of the claims relating to this patent are as follows:
1er "La qualité d'eau contenue dans le chaudron permet l'alimentation de plusieurs radiateurs."1st "The quality of water contained in the cauldron allows the supply of several radiators."
Or cette caractéristique étant commune à tous les récupérateurs d'âtre à fluide, elle n'apporte pas d'élément novateur.This characteristic being common to all fluid heaters, it does not provide any innovative element.
2e "L'amovibilité du couvercle permet uniquement la production d'eau chaude sanitaire."2nd "The removability of the cover only allows the production of domestic hot water."
Or dans le dispositif selon notre invention, la production d'eau chaude sanitaire n'est en aucune façon liée à l'amovibilité d'un couvercle.However, in the device according to our invention, the production of domestic hot water is in no way linked to the removable nature of a cover.
3e "Le chaudron est muni d'une anse pour être accroché à une crémaillère".3rd "The cauldron is provided with a handle to be hung on a rack".
Or cette caractéristique étant le propre de tout chaudron, cette revendication n'apporte pas d'innovation.However, this characteristic being the characteristic of any cauldron, this claim does not bring innovation.
Les caractéristiques des 4e et 5e revendications sont sans objet en ce qui concerne le dispositif selon notre invention.The characteristics of the 4th and 5th claims are not applicable with regard to the device according to our invention.
Les vertus essentielles d'une chaudière récupérateur de chaleur sont de capter, de canaliser, de concentrer en son coeur la chaleur, les flammes, les gaz de combustion dégagés par le feu de bois dans l'âtre et de restituer cette chaleur, sans altérer l'esthétique de la cheminée.The essential virtues of a heat recovery boiler are to capture, channel, concentrate in its heart the heat, the flames, the combustion gases released by the wood fire in the hearth and restore this heat, without altering the aesthetics of the fireplace.
Le dispositif selon l'invention nermet de concilier ces impératifs techniques et esthétiques tout en offrait de hautes performances. Il a en effet la particularité de se situer à l'aplomb du fover au coeur même de la source de chaleur et constitue avec le feu d'âtre une véritable chaudière à haut rendement .The device according to the invention makes it possible to reconcile these technical and aesthetic imperatives while offering high performance. It has the particularity of being located directly above the fover at the very heart of the heat source and, together with the hearth fire, constitutes a real high-efficiency boiler.
La chaudière, objet de rotre invention présente les caractéristiques et les avantages suivants c'est une chaudière d'âtre à foyer ouvert utilisant les fluides comme agent caloporteur. La combustion interne s'effectue dans de nombreuses chambres de combustion dont la forme conique ouverte vers le bas a été retenue pour f reiner les gaz de combustion et les fumées chaudes, les obligeant à lécher leur paroi interne, valorisait ainsi la comhustion et augmentant l' échange calorique. Le fond de la chaudière se caractérise par sa forme parabolique ainsi conçu pour capter, canaliser et concentrer les gaz de combustion, les flammes et les fumées chaudes à l'intérieur de la chaudière où s'effectue l'échange.The boiler, object of our invention has the following characteristics and advantages: it is an open hearth boiler using fluids as heat transfer agent. Internal combustion takes place in numerous combustion chambers, the conical shape of which, open downwards, has been retained to refine the combustion gases and hot fumes, forcing them to lick their internal wall, thus enhancing the combustion and increasing the caloric exchange. The bottom of the boiler is characterized by its parabolic shape, thus designed to capture, channel and concentrate the combustion gases, flames and hot fumes inside the boiler where the exchange takes place.
L'échange se fait par fluide selon un circuit forcé par des chicanes à travers tout le corps de la chaudière autour de chambres multiples de combustion ce qui permet d'obtenir une surface calorique importante par rapport au diamètre de la chaudière. Les chambres de combustion débouchent dans un collecteur de fumées situé au sommet de la chaudière. Dans sa partie postérieure, le collecteur est doté d'un dispositif de tirage à réglage automatique par thermostat de type spirale qui, en se dilatant, agit sur la clé de tirage située au-dessus de l'appareil. Ce réglage favorise la consommation rationnelle du combustible. Une position manuelle permet, grâce à l'obturation complète du tirare, l'utilisation de la cheminée en feu continu.The exchange is done by fluid according to a circuit forced by baffles through the whole body of the boiler around multiple combustion chambers which allows to obtain a large caloric surface compared to the diameter of the boiler. The combustion chambers open into a smoke collector located at the top of the boiler. In its rear part, the collector is equipped with a drawing device with automatic adjustment by a spiral type thermostat which, when expanding, acts on the drawing key located above the device. This setting promotes rational fuel consumption. A manual position allows, thanks to the complete closure of the tirare, the use of the chimney in continuous fire.
L'étude technique des forces (fond de la chaudière chambres de combustion, conduit d'évacuation des fumées vers le fond du foyer) permet d'améliorer sensiblement le tirage défectueux de certaines cheminées.The technical study of the forces (bottom of the combustion chamber boiler, smoke evacuation duct towards the bottom of the hearth) makes it possible to appreciably improve the defective draft of certain chimneys.
La partie supérieure de lachaudière constitue une trappe de visite donnant accès au dispositif de tirage automatique et manuel, au collecteur de fumées, aux chambres de combustion, à un purgeur automatique et à une soupane de sécurité.The upper part of the boiler constitutes an inspection hatch giving access to the automatic and manual drafting device, the smoke collector, the combustion chambers, an automatic vent valve and a safety valve.
Un dispositif de suspension, solidaire de la chaudière permet à c el l e-c i de se positionner automatiquement d'elle-même, au plus près et à l'aplomb de la source de chaleur par gravité en fonction de l'évolution du feu dans la cheminée.A suspension device, integral with the boiler allows it to position itself automatically, as close as possible and directly below the heat source by gravity according to the evolution of the fire in the fireplace.
Ce dispositif de suspension à coulisse est compensé par un ressort qui diminue la pression verticale de la chaudière sur les bûches. Il dissimule les tuyaux de raccordement. II comporte un verrouillage qui permet de maintenir la chaudière en position haute pour l'alimentation de l'âtre en combustible.This sliding suspension device is compensated by a spring which reduces the vertical pressure of the boiler on the logs. It conceals the connecting pipes. It includes an interlock which keeps the boiler in the high position for fuel supply to the hearth.
Une potence articulée supporte le dispositif de suspension à coulisse, solidaire de la chaudière par ses tuyaux d'alimentation. Elle est fixée sur le mur du fond de la cheminée dans la partie haute de la hotte. L'articulation de cette potence permet un déplacement latéral de la chaudière ce qui offre la possibilité à l'utilisateur de mieux suivre l'évolution horizontale du feu de bois ou de dégager une partie de l'âtre à d'autres fins (tournebroche, grill...) Ces déplacements horizontaux et verticaux de la chaudière sont possibles car elle est raccordée au circuit de chauffage central par l'intermédiaire de tuyaux flexibles éprouvés aux conditions de chaleur et de pression. Le branchement de ces flexibles se fait au moyen de raccords hydrauliques étanches dits de type rapide ; ce qui permet la dépose et la remise en place instantanées de la chaudière et de son dispositif de suspension, procurant les avantages suivants : dégagement du foyer our l'utilisation d'un grill, tournebroche , ramonage, utilisation de la même chaudière dans diverses cheminées préalablement dotées du même dispositif de raccordement (résidences secondaires)An articulated bracket supports the sliding suspension device, secured to the boiler by its supply pipes. It is fixed to the back wall of the chimney in the upper part of the hood. The articulation of this bracket allows a lateral displacement of the boiler which offers the user the possibility of better following the horizontal evolution of the wood fire or clearing part of the hearth for other purposes (rotisserie, grill ...) These horizontal and vertical displacements of the boiler are possible because it is connected to the central heating circuit by means of flexible pipes tested under the conditions of heat and pressure. The connection of these hoses is made by means of watertight hydraulic connections called rapid type; which allows instant removal and replacement of the boiler and its suspension device, providing the following advantages: clearing the fireplace for the use of a grill, rotisserie, sweeping, using the same boiler in various chimneys previously equipped with the same connection device (second homes)
