Abstract

The invention relates to a device which makes it possible to recover heat via a storage magazine brazier/hearth with triple combustion,upright,horizontal and inverted. It consists of an exchanger 1 which is situated in its lower part in the brazier/hearth 2 and in the upper part in the combustion chamber 3. It comprises a secondary air inlet 6 bis equipped with a fan controlled by thermostat which makes it possible to avoid risks of overheating. At the required temperature, the embers which are maintained by inlet of primary air 6 are activated by restarting the fan and automatically relight the wood stored in the storage magazine brazier/hearth 2. A perforated angle 47 for inlet of primary air makes possible a horizontal and inverted fire, and the same applies for the secondary air inlets 6 ter. A hood with two smoke outlets makes possible a normal decorative fire and a continuous fire.

Description

La présente invention a pour objet une addition au brevet principal 8302614 et concerne un récupérateur de chaleur', economiseur d'énergie, muni d'un brasier foyer étanche dont les inclinaisons permettent de récupérer les braises et un maximum d'énergie produitent par celles-ci. The present invention relates to an addition to the main patent 8302614 and relates to a heat recuperator ', energy saver, provided with a tight fire brazier whose inclinations make it possible to recover the embers and a maximum of energy produced by them. this.

Un double conduit de cheminée muni d'un avaloir avec trappe de fermeture permet le fonctionnement à feu ouvert décoratif ou à feu continu.A double chimney flue provided with a gully with closing hatch allows operation with decorative open fire or continuous fire.

Les avantages du récupérateur sont multiples, il permet de récu perer la chaleur par le rayonnement du feu normal et décoratif bois par les braises et par les gaz en combustion montante. Il s'installe dans une cheminée traditionnelle décorative, il sert aux particuliers, à la petite et moyenne industrie. Il est constitué par un triple foyer à triple combustion, feu decoratif normal sur chenets, feu par les braises tombant dans le brasier - chambre de combustion aui récu pere en combustion montante, feu par chambre de combustion charbon, gaz, fuel ou électrique. The advantages of the recuperator are multiple, it makes it possible to recover heat by the radiation of normal and decorative wood fire by embers and by gases in rising combustion. It is installed in a traditional decorative fireplace, it is used for individuals, small and medium industry. It is constituted by a triple hearth with triple combustion, normal decorative fire on crawlers, fire by embers falling in the brazier - combustion chamber which is recuperated in rising combustion, fire by combustion chamber with coal, gas, fuel or electric.

La figure 1 représente la vue en coupe de l'échangeur (1) nour la production d'eau chaude ou d'air chaud, ou mixte eau chaude - air chaud (fig 3). L'échangeur (1 et lbis) est à l'intérieur de la chambre de combustion (3). Le brasier-foyer (2) est un magasin de stokage des braises et du bois ou du charbon à feu continu. Sur le dessus du brasier - foyer (2) le feu est décoratif normal sur chenets et récupère par rayonnement. Au fur et à mesure de la combustion du bois les braises descendent dans le brasier-foyer (2) vers la grille (17) à ce moment la la combustion est montante0 Le placement des ventilations secondaires (6ter) permet la combustion horizontale, la position de ltéchangeur (17 bi s) retenant le bois permet la combustion inversée et horizontale. Figure 1 shows the sectional view of the exchanger (1) for the production of hot water or hot air, or mixed hot water - hot air (fig 3). The exchanger (1 and lbis) is inside the combustion chamber (3). The brazier-hearth (2) is a store for storing embers and wood or charcoal at continuous fire. On the top of the brazier - hearth (2) the fire is normal decorative on crawlers and recovers by radiation. As the wood burns the embers descend into the fire pit (2) towards the grate (17) at this time the combustion is rising 0 The placement of the secondary ventilation (6ter) allows horizontal combustion, the position the exchanger (17 bi s) retaining the wood allows reverse and horizontal combustion.

Donc trois combustions à la fois. Toutes les énergies sont récupérées. So three combustions at a time. All energies are recovered.

L'air secondaire arrive par ltentrée (6bis) ou par la partie arrière.Secondary air comes in through the inlet (6bis) or through the rear.

Un ventilateur controlé par un thermostat d'ambiance ou un aquastat peut être placé à cette entrée (6bis) pour pulserl'air secondaire, ce qui évite les risques de surchauffe.A fan controlled by a room thermostat or an aquastat can be placed at this inlet (6bis) to pulsate the secondary air, which avoids the risk of overheating.

Dans la chambre de combustion (3bis) un bruleur à mazout ou à gaz peut être placé. Les portes t14) peuvent être remplacees par une plaque coulissante pour réglage du débit de l'air primaire de la cor niére perforée (47). In the combustion chamber (3bis) an oil or gas burner can be placed. The doors t14) can be replaced by a sliding plate for adjusting the primary air flow rate from the perforated corner (47).

Pour les barbecues ou rotissoires une grille (17ter) légèrement inclinée peut être placée afin de retenir les braises et permet ltéva- cuation des cendres vers la grille (17). For barbecues or roasters a slightly inclined grid (17ter) can be placed in order to retain the embers and allows the evacuation of the ashes towards the grid (17).

La figure 2 représente une vue intérieure et extérieure du brasierfoyer (2) on y remarque le-tiroir 7 avec l'arrivée d'air primaire ou secondaire (6) pour feu montant, le four (32), la porte de chargement à feu continu (28), la grille (17), les arrivees d'air secondaire (6ter) et une cornière perforée (47) pour arrivée d'air primaire pour feu horizontal et inversé. Le caisson (48) du brasier-foyer (2) permet l'emboîtement de l'échangeur (1 et lbis) et de son enveloppe (19) (Pig3) qui est fermé par une trappe de visite pour nettoyage (19bis - Fig 5). FIG. 2 represents an interior and exterior view of the fire pit (2), there is the drawer 7 with the primary or secondary air supply (6) for rising fire, the oven (32), the loading door for fire continuous (28), the grid (17), the secondary air inlets (6ter) and a perforated angle iron (47) for primary air inlet for horizontal and inverted fire. The box (48) of the fire pit (2) allows the interlocking of the exchanger (1 and lbis) and its casing (19) (Pig3) which is closed by an inspection hatch for cleaning (19bis - Fig 5 ).

La figure 3 représente les échangeurs (1 et 1 bis) qui sont fermes par un embout (21) démontable pour le nettoyage des sorties des fumes (34). Les échangeus(let 1 bis) sont munis d'une entrée non figurée d'air frais ou pulsé par un ventilateur, cet air sort par la sortie (22). Figure 3 shows the exchangers (1 and 1a) which are closed by a removable tip (21) for cleaning the smoke outlets (34). The exchangers (let 1 bis) are provided with a non-figured inlet of fresh air or pulsed by a fan, this air exits through the outlet (22).

La figure (4) représente un avaloir (44) avec deux sorties de fumée, la sortie (49). pour le feu décoratif normal, la sortie (50) pour le feu continu bois, charbon, fuel ou gaz. Une trappe (43) peut fermer la sortie, (49). Figure (4) shows a drain (44) with two smoke outlets, the outlet (49). for normal decorative fire, the outlet (50) for continuous wood, coal, fuel or gas fire. A hatch (43) can close the outlet, (49).
