Description

Brûleur à gazéification Gasification burner
La présente invention concerne un brûleur à gazéification et son alimentation, adaptables à une cheminée à foyer fermé, permettant de transformer cette cheminée à bois en cheminée à combustible liquide. Une cheminée à bois, à foyer fermé, présente des contraintes de manutention du combustible et d'entretien du foyer qui nuisent à une utilisation continue.The present invention relates to a gasification burner and its supply, adaptable to a closed hearth chimney, making it possible to transform this wood chimney into a liquid fuel chimney. A wood-burning fireplace, with a closed hearth, presents fuel handling and home maintenance constraints that hinder continuous use.
Le dispositif, selon l'invention, permet de remédier à ces inconvénients, par exemple pour une puissance de 2 à 14 kw. Il comprend deux parties distinctes : La première partie est le dispositif d'amenée du combustible.The device according to the invention overcomes these drawbacks, for example for a power of 2 to 14 kw. It includes two separate parts: The first part is the fuel supply device.
Ce dispositif comprend une alimentation classique (mini-réservoir, filtre, électrovannes, cuve à niveau constant), un séparateur air-liquide, et un tube incliné à double paroi, dont l'extrémité finale terminée par deux tubes coudés vers le bas, de faible diamètre, séparés de quelques millimètres, pénètre à l'intérieur de la cheminée à travers la base arrière de l'avaloir et arrive à la verticale du centre du brûleur.This device includes a conventional supply (mini-tank, filter, solenoid valves, constant level tank), an air-liquid separator, and a double-walled inclined tube, the final end of which ends in two bent down tubes, small diameter, separated by a few millimeters, penetrates inside the chimney through the rear base of the outlet and arrives vertically from the center of the burner.
La partie externe à la cheminée du tube comprend une croix permettant le remplissage en eau distillée, à travers un tube souple transparent pour contrôler le niveau d'eau, et le contrôle continu de la pression, par un classique manomètre; le tout formant un radiateur étanche pour le refroidissement de la partie interne. La partie interne à la cheminée du tube est maintenue par un tube plus gros, terminé par une partie verticale descendante protégeant le liquide combustible après sa sortie du tube d'amenée. Pour un maximum d'efficacité, ce tube peut être doublé par un tube de diamètre plus important ou dans sa partie verticale par un refroidisseur récupérateur de chaleur air-eau de forme adaptée. Ce tube peut pivoter à l'intérieur de son support autour du tube d'amenée, afin de dégager le foyer par exemple en période d'utilisation au bois.The external part of the tube chimney includes a cross allowing filling with distilled water, through a transparent flexible tube to control the water level, and continuous pressure control, by a conventional pressure gauge; the whole forming a sealed radiator for cooling the internal part. The internal part of the chimney of the tube is held by a larger tube, terminated by a vertical descending part protecting the combustible liquid after it leaves the supply tube. For maximum efficiency, this tube can be doubled by a tube of larger diameter or in its vertical part by an air-water heat recovery cooler of suitable shape. This tube can pivot inside its support around the supply tube, in order to free the hearth, for example during periods of use with wood.
Il peut également servir, en période d'utilisation au bois pour la mise en route d'une flambée, en imprégnant le combustible solide d'une partie de combustible liquide.It can also be used, during periods of use for wood to start an outbreak, by impregnating the solid fuel with a portion of liquid fuel.
La pente continue du double tube permet d'une part l'écoulement, par gravité du combustible liquide dans le tube interne de faible diamètre, et d'autre part, le refroidissement de ce même combustible par l'effet caloduc de l'eau déminéralisée située dans le tube externe entourant le combustible. L'eau circule dans le tube et refroidit le tube injecteur.The continuous slope of the double tube allows on the one hand the flow, by gravity of the liquid fuel in the internal tube of small diameter, and on the other hand, the cooling of this same fuel by the heat pipe effect of demineralized water located in the outer tube surrounding the fuel. Water flows through the tube and cools the injector tube.
La température de ce dernier reste donc dans des limites très acceptables. Une pression d'eau à froid de l'ordre de 0,5 bar est une bonne moyenne. Cette première partie est considérée comme fixe par rapport à la cheminée.The temperature of the latter therefore remains within very acceptable limits. Cold water pressure of around 0.5 bar is a good average. This first part is considered fixed relative to the chimney.
La deuxième partie assurant la combustion, est l'ensemble posé au centre du foyer. Cet ensemble comporte deux parties distinctes.The second part ensuring combustion, is the assembly placed in the center of the fireplace. This set has two separate parts.
La première est le caisson amenant l'air frais nécessaire à la combustion.The first is the box supplying the fresh air necessary for combustion.
Ce caisson a une forme adaptée à chaque type de cheminée afin de faire correspondre l'entrée d'air de la cheminée à l'entrée d'air du caisson. Ce caisson renferme un ventilateur hélicoïde plat à axe vertical, correspondant à l'axe de chute du liquide; ce ventilateur à vitesse variable peut être un ventilateur basse tension.This box has a shape adapted to each type of chimney in order to match the air inlet of the chimney to the air inlet of the box. This box contains a flat axial fan with a vertical axis, corresponding to the axis of fall of the liquid; this variable speed fan can be a low voltage fan.
La deuxième partie est le foyer proprement dit, posé sur un support circulaire embouti à la verticale du ventilateur, en butée sur deux vis arrières de réglage situées à 120° l'une de l'autre.The second part is the hearth proper, placed on a circular support stamped vertically from the fan, abutting on two rear adjustment screws located at 120 ° from one another.
En son centre est posé un réceptacle évaporateur ayant la forme d'un "chapeau mexicain" monobloc ou en deux parties. La partie conique, à faible angle au sommet, reçoit les gouttes de liquide carburant et évite à celles-ci de gicler dans le brûleur. Le réceptacle, construit en vitrocéramique de préférence, est d'un nettoyage aisé. Son centrage est assuré par une pièce circulaire munie de six tiges, ou par un emboutissage au fond du brûleur.In its center is placed an evaporator receptacle having the shape of a "Mexican hat" in one piece or in two parts. The conical part, at a slight angle at the top, receives the drops of fuel liquid and prevents them from spurting into the burner. The receptacle, preferably made of ceramic glass, is easy to clean. Its centering is ensured by a circular part provided with six rods, or by a stamping at the bottom of the burner.
A l'intérieur du brûleur, plusieurs étages horizontaux de disques pleins ou en grillage ou métal déployé ou tôle perforée, séparés les uns des autres par des entretoises tubulaires, assurent une bonne combustion, avec un effet de braises.Inside the burner, several horizontal stages of solid or mesh discs or expanded metal or perforated sheet, separated from each other by tubular spacers, ensure good combustion, with an embers effect.
Un tube central protège les gouttes de liquide carburant du contact direct des flammes.A central tube protects the drops of fuel liquid from direct contact with the flames.
La construction la plus simple comprend l'enveloppe centrale avec fond, le tout en métal, posée sur l'enveloppe extérieure en vitrocéramique transparente. Une pièce intermédiaire assure le supportage et le centrage.The simplest construction includes the central envelope with bottom, all in metal, placed on the outer envelope in transparent glass ceramic. An intermediate piece provides support and centering.
Le pot de combustion peut être un embouti du commerce, tel qu'un autocuiseur.The burn pot can be a commercial stamp, such as a pressure cooker.
L'enveloppe extérieure permet de voir le rougeoiement du pot et la combustion ponctuellement, à travers les trous d'injection d'air du pot. La construction la plus sophistiquée comprend les deux enveloppes en vitrocéramique transparente, qui permettent une vision totale de la combustion.The outer casing makes it possible to see the reddening of the pot and the punctual combustion, through the air injection holes of the pot. The most sophisticated construction includes the two transparent glass-ceramic casings, which allow a total view of the combustion.
Des ailettes verticales disposées radialement entre les deux parois, permettent d'éliminer l'effet tourbillonna ire dû au ventilateur, cet effet amenant une mauvaise combustion. Sous le pot de combustion, une tôle située à quelques millimètres, protège le ventilateur de la chaleur due au rayonnement direct émis par le fond du pot. Une forme emboutie en tôle, favorise l'écoulement de l'air. Derrière le foyer, une portion de tôle polie en arc de cercle à axe vertical, réfléchit la lumière issue du foyer vers l'avant.Vertical fins arranged radially between the two walls, eliminate the swirling effect due to the fan, this effect causing poor combustion. Under the burn pot, a sheet located a few millimeters, protects the fan from heat due to direct radiation emitted from the bottom of the pot. A stamped sheet metal shape promotes air flow. Behind the fireplace, a portion of polished sheet metal in an arc with a vertical axis, reflects the light from the fireplace forward.
Deux thermocouples, en partie haute du foyer, assurent la sécurité du système, en agissant sur deux électro vannes normalement fermées, placées en série sur le circuit combustible. Un contacteur permet d'ouvrir les deux électro vannes au moment de l'allumage.Two thermocouples, in the upper part of the hearth, ensure the safety of the system, by acting on two normally closed solenoid valves, placed in series on the fuel circuit. A contactor allows the two solenoid valves to be opened at the time of ignition.
L'alimentation par gravité, peut aussi être remplacée par un système utilisant une micro-pompe à débit variable. Le séparateur air-liquide n'est alors plus nécessaire. L'ensemble complet brûleur-amenée du combustible peut être un système autonome de chauffage, sans être implanté obligatoirement dans une cheminée.Gravity feed can also be replaced by a system using a variable flow micro-pump. The air-liquid separator is no longer necessary. The complete burner-fuel supply assembly can be an independent heating system, without necessarily being installed in a chimney.
Il est bien entendu conseillé d'avoir un système récupérateur de chaleur sur les gaz brûlés, afin de conserver un rendement correct à installation. Cela peut être un refroidisseur récupérateur de chaleur air-eau, directement installé dans les flammes du foyer qui réduira alors la température du combustible avant combustion.It is of course advisable to have a heat recovery system on the burnt gases, in order to maintain correct performance at installation. This can be an air-water heat recovery cooler, directly installed in the flames of the fireplace which will then reduce the temperature of the fuel before combustion.
Tous les éléments seront construits en matériaux résistants à la corrosion, par exemple : - accessoires avant tube injecteur : cuivre.All elements will be made of corrosion resistant materials, for example: - accessories before injector tube: copper.
- tube injecteur plus refroidisseurs : cuivre ou mieux acier inox.- injector tube plus coolers: copper or better stainless steel.
- accessoires de maintien des refroidisseurs : acier inox.- cooler holding accessories: stainless steel.
- caisson : alliage d'aluminium.- housing: aluminum alloy.
- composants foyer : acier inox réfractaire ou vitrocéramique, acier inox. - écran réfléchissant : aluminium poli.- fireplace components: refractory or glass ceramic stainless steel, stainless steel. - reflective screen: polished aluminum.
La construction modulaire permet un échange aisé de certaines pièces. Les éléments internes du pot étant simplement posés dans ce pot, et celui-ci étant posé sans fixation sur le caisson, il s'ensuit une manutention très aisée pour un nettoyage facile du foyer. L'extrémité du tube injecteur du carburant, étant située au fond du tube protecteur vertical, elle n'est pas atteinte par les produits de combustion et reste ainsi propre très longtemps. Cette extrémité étant terminée par deux tubes coudés vers le bas de faible diamètre, l'écoulement du combustible se fait sans dispersion quelque soit le débit affiché (dans les limites fixées initialement). Lors de la mise en route, il est nécessaire d'utiliser un carburant complémentaire, comme de l'alcool à brûler, pour assurer le préchauffage du brûleur.The modular construction allows easy exchange of certain parts. The internal elements of the pot being simply placed in this pot, and the latter being posed without attachment to the box, it follows very easy handling for easy cleaning of the hearth. The end of the fuel injector tube, being located at the bottom of the vertical protective tube, it is not reached by the combustion products and thus remains clean for a very long time. This end being terminated by two bent downward tubes of small diameter, the flow of fuel is done without dispersion whatever the displayed flow rate (within the limits initially set). When starting up, it is necessary to use an additional fuel, such as methylated spirits, to ensure the preheating of the burner.
Par la suite, il suffit d'adapter la vitesse de rotation du ventilateur, au débit du liquide carburant, pour assurer la meilleure combustion (sans fumée ni flamme importante).Thereafter, it suffices to adapt the speed of rotation of the fan, to the flow rate of the fuel liquid, to ensure the best combustion (without significant smoke or flame).
