Abstract
Description
a plésente invention concerne un éconor iseir destiné à équiper les installations de chauffage comportant une chaudière à eau chaude avec son tuyau de fumée et un brûleur automatique à fuel domestique. he present invention relates to an iseir econor intended to equip heating installations comprising a hot water boiler with its smoke pipe and an automatic burner for domestic fuel.
Dans les installations connues de ce genre, l'eau de retour s'écoule en permanence par l'économ iseur, ce qui cause une déperdition de chaleur lorsque le conduit de fumée s est refroidi. Les gains de consommation obtenus n'atteignent que rarement 20 %. In known installations of this kind, the return water continuously flows through the economiser, which causes heat loss when the flue is cooled. The consumption gains obtained only rarely reach 20%.
Le dispositif selon l'invention, combinant à la fois un économiseur plus performant etun système de by-pass déviant l'eau de retour hors de l'économiseur lorsque le brûleur est à l'arrêt, permet d'obtenir des économies bien supérieures. Le texte qui suit décrit en détail une des réalisationrpossibies de cette invention. The device according to the invention, combining both a more efficient economizer and a by-pass system diverting the return water out of the economizer when the burner is off, makes it possible to obtain much greater savings. The following text describes in detail one of the embodiments of this invention.
La P 1. 1/2 fig. 1 montre une chaudière 1 avec l'économiseur 2 placé daits le conduit de fumée 3. Le bruiteur 4 fonctionne, la pompe 5 tourne et a ouvert le clapet 6. The P 1. 1/2 fig. 1 shows a boiler 1 with the economizer 2 placed in the smoke pipe 3. The buzzer 4 works, the pump 5 turns and has opened the valve 6.
L'eau s'écoule comme l'indiquent les flèches par l'économiseur 2 et rentre à la chaudière 1. La fig. 2 montre la même chaudière 1 et son économiseur 2. Le brûleur 4 est à l'arrêt. La pompe 5 est également à l'arrêt et a fermé Je clapet6. Maintenant la pompe do recyclage 7 tourte eut a ouvert le clapet 8. L'eau ne s'écoule plus par ltéco- nomiseur 2 mais par le retour de l'installation 9 vers le chaudière 1 comme l'indiquent les flèches. S i l'installation n 'est pas équipée d 'une pompe de recyclage, elle fonctionne en thermo-siphon.The water flows as indicated by the arrows through the economizer 2 and returns to the boiler 1. Fig. 2 shows the same boiler 1 and its economiser 2. The burner 4 is stopped. Pump 5 is also stopped and closed valve 6. Now the recirculation pump 7 has already opened the valve 8. The water no longer flows through the economizer 2 but through the return of the installation 9 to the boiler 1 as indicated by the arrows. If the installation is not equipped with a recycling pump, it operates as a thermo-siphon.
Pour obtenir ce fonctionnement, nous avons adapté un équipement électrique particulier. La P 1. 2/2 en montre le fonctionnement avec une pompe de recyclage. Sur cette planche est représenté un contacteur-inverseur 10 qui établira simultanément le courant soit fig. 1 sur la pompe 5 de l'économiseur pendant le fonctionnement du brûleur 4, soit fig. 3 sur la pompe de recyclage 7 de l'installation lorsque le brûleur est à l'arrêt et que le thermostat d'ambiance 11 de l'appartement est fermé. La fig. 2 montre le thermos- tatde chaudière 12 fermé. le brûleur 4 fonctionne, la pompe 5 tourne par le contacteur 10 quistestenclenché. Sur cette meme figure, le thermostat d'appartement 11 s'est fer- mé mai la pompe de l'économiseur conserve la priorité par le contacteur 10.Fig. 3 si le thernostat de chaudière 12 est ouvert, ie bru leur est à l'arrêt, le contacteur 10 s 'est mis cn repos, a stoppé la pompe 5 de l'économiseur et a mis en circulation la pompe 7 de l'installation par le thermostat 11 d'appartementquiestfermé. Fig. 4 :sile thermos taude chaudière 12 ainsi crue celui de l'appartement 11 sont ouverts, le brûleur 4 etla rompe 5 de l'économiseur sont à l'arrêt. La pompe 7 de l'installation est également a l'arrêt.La pompe 5 de l'économiseur aura toujours la priori@é par le contacteur-inver- seur 10 si le thermostat de chaudière 12 se ferme pour mettre en route le brûleur 4. Un aquastat de sécurité 13 est placé en es d'élévation anormale de la température de l'eau dans l'économiseur. Un interrupteur (dit fin de course) 14 établit le courant dans l'installation lorsque la vanne d'isolement 15 fig. 5 est en position ouverture. To achieve this function, we have adapted specific electrical equipment. P 1. 2/2 shows how it works with a recycling pump. On this board is shown a reversing contactor 10 which will simultaneously establish the current, or fig. 1 on the pump 5 of the economizer during the operation of the burner 4, or fig. 3 on the recycling pump 7 of the installation when the burner is off and the room thermostat 11 of the apartment is closed. Fig. 2 shows the boiler thermostat 12 closed. the burner 4 operates, the pump 5 rotates by the contactor 10 which is switched on. In this same figure, the apartment thermostat 11 has closed but the economizer pump retains priority by the contactor 10.Fig. 3 if the boiler thermostat 12 is open, ie the mist is stopped, the contactor 10 has come to rest, has stopped the pump 5 of the economizer and has circulated the pump 7 of the installation by the apartment thermostat 11 which is closed. Fig. 4: if thermos taude boiler 12 thus raw that of apartment 11 are open, the burner 4 and the rupture 5 of the economizer are stopped. The pump 7 of the installation is also stopped. The pump 5 of the economizer will always have priority by the contactor-inverter 10 if the boiler thermostat 12 closes to start the burner 4 A safety aquastat 13 is placed in an abnormal rise in the water temperature in the economizer. A switch (called limit switch) 14 establishes the current in the installation when the isolation valve 15 fig. 5 is in the open position.
La P 1. 1/2 fig. 1 montre le dess@. d'une chaudière 1 . L'économiseur 2 est placé dans le tuyau de fumée 3 qui se raccorde directement sur la buse 16 de la chaudière 1. The P 1. 1/2 fig. 1 shows the dess @. of a boiler 1. The economizer 2 is placed in the smoke pipe 3 which is connected directly to the nozzle 16 of the boiler 1.
Par un té 17 sur lequelestplacé en dérivation un tuyau de fumée 18 avec son volet 19 permettant de faire un réglage de débit des gaz sur l'économiseur 2.By a tee 17 on which is placed in derivation a smoke pipe 18 with its flap 19 making it possible to adjust the gas flow rate on the economizer 2.
La Pi. 2/2 fig. 5, 6, 7, montre cet économiseur. Pour sa grande transmission de la chaleur, il est entièrement réalisé en cuivre rouge. Il comprend un tube d'entrée 20 dans un tube en forme d'anneau 21, son tube de sortie 22 partant d'un second anneau 23. The Pi. 2/2 fig. 5, 6, 7, shows this economizer. For its great heat transfer, it is made entirely of red copper. It comprises an inlet tube 20 in a ring-shaped tube 21, its outlet tube 22 starting from a second ring 23.
Le diamètre extérieur de ces deux anneaux est sensiblement égal au diamètre intérieur du tuyau de fumée utilisé. Reliant les deux anneaux perpendiculairement, plusieurs tubes, 24, forment un cylindre au centre duquelestplacé fig. 6 un serpentin conique 25 dont la base est soudée à l'anneau 23 et le sommet à l'anneau 21. Autour des tubes 24 fig. 5 formant un cylindre, sont enroulés plusieurs serpentins 26 fig. 7, chacun étant relié aux anneaux 21, 23. L'eau circule à l'intérieur de chacun de ces trois éléments bien distincts 24 fig. 5, 25 fig. 6, 26 fig. 7. L'économiseur est également équipé de deux raccords démontables 27 et 28, d'un doigt de gant 29 destiné à recevoir laquas- tat de sécurité 13 fig. 4 et une vanne dont la poignée 15 repose sur un interrupteur fin de course 14 fig. 4 et établit le courant dans l'installation seulement en position ouverture.The outside diameter of these two rings is substantially equal to the inside diameter of the smoke pipe used. Connecting the two rings perpendicularly, several tubes, 24, form a cylinder in the center of which is placed fig. 6 a conical coil 25 whose base is welded to the ring 23 and the top to the ring 21. Around the tubes 24 fig. 5 forming a cylinder, several coils 26 are wound. 7, each being connected to the rings 21, 23. The water circulates inside each of these three very distinct elements 24 fig. 5, 25 fig. 6, 26 fig. 7. The economizer is also equipped with two removable connectors 27 and 28, a thermowell 29 intended to receive the safety status 13 fig. 4 and a valve whose handle 15 rests on a limit switch 14 fig. 4 and establishes the current in the installation only in the open position.
Les tests pratiqués sur une installation ainsi équipée mortrentque 55 mn sont nécessaires pour élever la températeure de l'eau de 120 à 600 C . Avec ce dispositif, 31 mn suffisent. The tests carried out on an installation thus equipped with a death rate of 55 min are necessary to raise the water temperature from 120 to 600 C. With this device, 31 minutes are enough.
Sur une seconde installation, pour la même opération, sans le dispositif, 262 cl de fuel sont utilisés, avec ce dispositif, objet de l'invention, 138 cl suffisent. On a second installation, for the same operation, without the device, 262 cl of fuel are used, with this device, object of the invention, 138 cl is sufficient.
On peut donc conc lure une économ ie d 'environ 40 % . A savings of around 40% can therefore be calculated.
