Abstract

The invention relates to a domestic fuel oil central heating boiler, with a fire-preventing draught cut-off flap. The invention relates to a boiler equipped with an exchanger made from copper tubing 10 resting on a perforated refractory plate, this exchanger being in circulation with a coil 6 wound at the top of the boiler around the flue 9. The invention applies to fuel-oil-fired central heating technology.

Description

La présente invention à pour objet une chaudière à fuël domestique pouvant faire une économie d'énergie de 1' ordre de 50 à 70 % suivant les oas ,cette économie par la faible tempFra- ture de sortie des fumées 40 à 45 et par I2 de C.0.2,les
Chaudières de ce type ayant actuellement des sorties de fumée variant entre 200 et 2500 ,certaines anciennes chaudière ayant des températures de sortie de fumées qui vont jusqu'à 5000 la présente comporte:Une chambre de combustion en briques refra- otaire ,une jupe en réfractaire entourant l'échangeur prinoipal en aoier(pour le chauffage central),l'échangeur secondaire en tube ouiore(pour l'eau sanitaire)reposant sur la partie supéri- eure en réfractaire perçée de trous pour le passage des calories et des fumées venant du foyer.Le foyer est constitué par 5 plaques réfractaire I) percée pour le passage du brdleur,I) plaque de sol,I plaque de fond, 2) plaques latérales,ces plaques sont accolées à la paroi intérieure en acier contenant une lame d' eau destinée al'alimentation du circuit chauffage,l'échangeur principal en aoier et en tubes est constitué par un coffre en tôle d'acier percé de trous pour le passage des calories et des fumées remontant du foyer,ce coffre est placé horizontalement sur ce ooffre est placé 2 coffres vbrtioaux dans lesquelles viennent se rejoindre les tubes du faisceau tubulaire,tout oe bloo est relié au haut de la chaudière par des tuyauteries pour permettre la circulation de l'eau du chauffage,cet ensemble est également entouré de 5 plaques réfractaire I) plaque de façade
I) plaque de fond, I plaque de dessus percée de trous pour le passage des calories,2 plaques latérales,sur la plaque réfractai- re du dessus percée de trous repose un deuxièmme échangeur en tubes cuivre , dans lesquelles circule l'eau pour le sanitaire.
The present invention relates to a domestic fuël boiler which can make an energy saving of 1 order of 50 to 70% depending on the oas, this saving by the low smoke outlet temperature 40 to 45 and by I2 of C.0.2, the
Boilers of this type currently having smoke outlets varying between 200 and 2500, some old boilers having smoke outlet temperatures which go up to 5000 this one comprises: A combustion chamber in refractory bricks, a skirt in refractory surrounding the main stainless steel heat exchanger (for central heating), the secondary heat exchanger in tube yesore (for domestic water) resting on the upper part in refractory pierced with holes for the passage of calories and fumes coming from the The hearth is made up of 5 refractory plates I) pierced for the passage of the burner, I) floor plate, I bottom plate, 2) side plates, these plates are attached to the inner steel wall containing a blade of water intended for the supply of the heating circuit, the main heat exchanger in aoier and in tubes is constituted by a sheet steel box pierced with holes for the passage of calories and fumes rising from the hearth, this box is placed horizontal ment on this ooffre is placed 2 vbrtioaux chests in which come to join the tubes of the tube bundle, all oe bloo is connected to the top of the boiler by pipes to allow the circulation of the water of heating, this set is also surrounded by 5 refractory plates I) front plate
I) bottom plate, I top plate pierced with holes for the passage of calories, 2 side plates, on the refractory plate above pierced with holes rests a second exchanger in copper tubes, in which the water circulates for sanitary.

Ces deux échangeurs et les plaques réfractaire sont entourés d'un coffre en tôle d'acier d'épaisseur appropriée,percé sur sa partie supérieure pour le passage des fumées et des calories vers la boite à fumées,autour de ce ooffre circule l'eau du circuit chauffage et de l'enveloppe extérieure également d'épaisseur appropriée.Lapartie haute de la chaudière est en relation directe
aveo la circulation d'eau entourant le coffre de la partie basse
cette eau entoure la boite à fumées et le serpentin cuivre qui sert à la fourniture d'eau sanitaire,ce serpentin est en relation par thermosiphon avec l'échangeur en cuivre l'échangeur acier tubulaire est lui aussi également en relation par thermosiphon avec le haut de la chaudière et le circuit chauffage ,la sécurité est assurée par une soupape placée sur le point haut de l'installation,d'un vase dtexpansion type flexcon à pression d'azôte, d'un aquastat de sécurité ,d'un aquastat gradué en degré pour le réglage de la température d'un thermomètre .Le départ chauffage est placé au centre du haut de chaudière avec une vanne 4 voies,le retour des radiate- urs en bas du coffre de l'échangeur principal .La porte de cette ohaudière est également à lame d'eau entre deux parois métalli@- ue,cette lame d'eau est en circulation sveo le oirouit chauffage par le raccordement de deux tuyauteries haute et basse et 4 robinets de fermeture et d'ouverture,ces robinets permettent le démontage de la porte sans vidanger l'installation de chauf- fage,pour le ramonage du foyer et des deux échangeurs,cette porte est fixée par 4 goujons
Sur la boite à fumées est placé,un clapet coupe-tirage ,qui est actionné par un vérin,lui même agissant sous la pression de la pompe à fuël du brûleur,la transmission entre clapet et vérin se fait par tringle ou autre possibilité par cable guidé par des poulies, ce clapet est muni d'un anti-déflagrant pour la sécuri- té.
These two exchangers and the refractory plates are surrounded by a sheet steel box of appropriate thickness, pierced on its upper part for the passage of smoke and calories to the smoke box, around this supply circulates water of the heating circuit and of the outer casing, also of appropriate thickness. The upper part of the boiler is in direct relation
with the circulation of water surrounding the trunk of the lower part
this water surrounds the smoke box and the copper coil which is used for the supply of sanitary water, this coil is in relation by thermosyphon with the copper exchanger the tubular steel exchanger is also also in relation by thermosyphon with the top of the boiler and the heating circuit, safety is ensured by a valve placed at the highest point of the installation, a expansion vessel of the flexcon type with azote pressure, a safety aquastat, a graduated aquastat in degrees for adjusting the temperature of a thermometer. The heating flow is placed in the center of the top of the boiler with a 4-way valve, the return of the radiators at the bottom of the trunk of the main exchanger. ohaudière is also with a sheet of water between two metal walls - this, this sheet of water is in circulation sveo the oirouit heating by the connection of two high and low pipes and 4 closing and opening taps, these taps allow disassembly of the por without draining the heating installation, for sweeping the fireplace and the two exchangers, this door is fixed by 4 studs
On the smoke box is placed a draft valve, which is actuated by a jack, itself acting under the pressure of the burner fuel pump, the transmission between valve and jack is by rod or other possibility by cable guided by pulleys, this valve is fitted with an explosion-proof device for safety.
