Description

L'invention concerne une installation pour la combustion de combustible liquide, notamment du type produits pétroliers, dont les brûleur sont montés sur des appareils de combustion tels que, par exemple, chaudières, fours, etc.The invention relates to an installation for the combustion of liquid fuel, in particular of the petroleum product type, the burners of which are mounted on combustion devices such as, for example, boilers, ovens, etc.

L'invention se propose plus particulièrement de concevoir une installation permettant d'utiliser des combustibles liquides de mauvaise qualité, jusqu'à présent inutilisables de façon rentable, car contenant une proportion importante de déchets non combustibles.The invention more particularly proposes to design an installation making it possible to use liquid fuels of poor quality, hitherto unusable in a cost-effective manner, since it contains a large proportion of non-combustible waste.

L'invention est caractérisée en ce que elle comporte un premier bassin dit de décantation, alimenté en combustible et relié par un trop-plein à un second bassin dit de stockage, ce second bassin étant relié au brûleur pour son alimentation en combustible.The invention is characterized in that it comprises a first so-called settling tank, supplied with fuel and connected by an overflow to a second so-called storage tank, this second tank being connected to the burner for its supply of fuel.

Suivant une autre caractéristique de l'invention, le premier bassin dit de décantation comporte un moyen de chauffage dont le fonctionnement est contrôlé par un thermostat.According to another characteristic of the invention, the first so-called settling tank comprises a heating means, the operation of which is controlled by a thermostat.

Suivant une autre caractéristique de l'invention, le second bassin dit de stockage, comporte un détecteur de niveau relié à une pompe disposée dans le circuit d'alimentation en combustible du premier bassin dit de décantation.According to another characteristic of the invention, the second so-called storage tank comprises a level detector connected to a pump dis placed in the fuel supply circuit of the first so-called settling tank.

Suivant une autre caractéristique de l'invention, le trop-plein reliant le premier bassin dit de décantation, au second bassin dit de stockage, est constitué par une cloison séparant les deux bassins et dont le bord supérieur détermine le niveau de déversement du combustible.According to another characteristic of the invention, the overflow connecting the first so-called settling tank, to the second so-called storage tank, is constituted by a partition separating the two tanks and whose upper edge determines the level of fuel spillage.

L'invention est représentée à titre d'exemple non limitatif sur les dessins ci-joints dans lesquels :

  • - la figure 1 représente l'installation de l'invention ;
  • - la figure 2 est une vue latérale schématique du brûleur de la figure 1 ;
  • - la figure 3 est une vue schématique de gauche de la figure 2.
The invention is shown by way of nonlimiting example in the accompanying drawings in which:
  • - Figure 1 shows the installation of the invention;
  • - Figure 2 is a schematic side view of the burner of Figure 1;
  • - Figure 3 is a schematic left view of Figure 2.

La présente invention a, en conséquence, pour but de réaliser une installation de construction simple et de fonctionnement sûr, qui assure notamment la combustion de produits pétroliers de mauvaise qualité et, par exemple, les huiles de vidange de moteur et cela quelle que soit la température ambiante.The present invention therefore aims to achieve a simple construction installation and safe operation, which in particular ensures the combustion of poor quality petroleum products and, for example, engine drain oils and that whatever the ambient temperature.

Suivant l'invention, le produit combustible liquide devant être utilisé est stocké ( voir figure 1 ) dans une cuve 10 qui peut être, de façon connue, enterrée ou disposée sur le sol. Une pompe 12 assure le transfert de ce combustible, par passage au travers d'une canalisation 16, dans un bassin de décantation 18. Un filtre 14 est disposé sur cette canalisation 16.According to the invention, the liquid combustible product to be used is stored (see Figure 1) in a tank 10 which can be, in known manner, buried or arranged on the ground. A pump 12 ensures the transfer of this fuel, by passage through a pipe 16, into a settling tank 18. A filter 14 is placed on this pipe 16.

Le bassin de décantation 18 est pourvu d'un moyen de chauffage permettant de maintenir la température nécessaire à la décantation. Dans cette exemple de réalisation, ces moyens de chauffage sont constitués par une résistance chauffante 20, contrôlée par un thermostat 22. Grâce à cette disposition, la décantation, dans ce bassin 18, s'effectue par une précipitation des particules lourdes ( déchets ) vers le bas. Les déchets sont récupérés dans la partie inférieure, de forme conique, du bassin 18, et on les évacue périodiquement par les orifices 24.The settling tank 18 is provided with a heating means making it possible to maintain the temperature necessary for settling. In this exemplary embodiment, these heating means consist of a heating resistor 20, controlled by a ther mostat 22. Thanks to this arrangement, decantation in this basin 18 is carried out by precipitation of the heavy particles (waste) downwards. The waste is collected in the lower conical part of the basin 18, and is periodically removed through the orifices 24.

Les produits combustibles plus légers se maintiennent dans la partie supérieure du bassin de décantation et ils passent, par déversement, au-dessus d'une cloison 30, dans un bassin de stockage 26. Le niveau, dans ce bassin 26, est maintenu à une valeur constante. A cet effet, le fonctionnement de la pompe 12 est asservi à la valeur de ce niveau par l'intermédiaire d'un niveau-contact 28. Toute diminution de la hauteur du combustible épuré dans le bassin 26, détectée par le niveau-contact 28, provoque la mise en marche de la pompe 12, qui assure aussitôt la compensation. Pour assurer une vidange de ce bassin 26, on prévoit des orifices 24' à son extrémité inférieure.The lighter combustible products are maintained in the upper part of the settling tank and they pass, by pouring, over a partition 30, into a storage tank 26. The level in this tank 26 is maintained at a constant value. To this end, the operation of the pump 12 is controlled by the value of this level via a contact level 28. Any reduction in the height of the purified fuel in the tank 26, detected by the contact level 28 , causes the pump 12 to start up, which immediately ensures compensation. To ensure emptying of this basin 26, holes 24 ′ are provided at its lower end.

Le bassin de stockage 26, maintenu à un niveau constant, alimente en combustible débarrassé d'impuretés un brûleur 32. Cette alimentation s'effectue de la façon suivante.The storage tank 26, maintained at a constant level, supplies fuel freed of impurities to a burner 32. This supply takes place as follows.

Le bassin de stockage 26 est relié au brûleur 32 par une canalisation d'alimentation 34, sur laquelle sont interposés une vanne 36, à commande manuelle ou électrique, permettant l'obstruction de la canalisation en cas de besoin, un filtre mécanique 40 et un filtre magnétique 38 terminant la filtration du combustible alimentant le brûleur 32.The storage tank 26 is connected to the burner 32 by a supply pipe 34, on which are interposed a valve 36, with manual or electrical control, allowing the obstruction of the pipe if necessary, a mechanical filter 40 and a magnetic filter 38 terminating the filtration of the fuel supplying the burner 32.

Une canalisation de retour 42, pourvue d'un clapet anti-retour 44, assure le retour du combustible non consommé par le brûleur au bassin de stockage 26.A return line 42, provided with a non-return valve 44, ensures the return of the fuel not consumed by the burner to the storage tank 26.

L'installation comporte, en outre, une armoire électrique 46 renfermant les diverses commandes des différentes opérations, ainsi que les voyants de contrôle indispensables.
Sur le bassin de stockage 26 est fixé une jauge 48, permettant de vérifier à tout moment le niveau du combustible épuré dans le bassin de stockage.The installation further comprises an electrical cabinet 46 containing the various controls for the various operations, as well than the essential control lights.
A storage tank 48 is fixed on the storage tank 26, making it possible to check the level of purified fuel in the storage tank at any time.

Le brûleur, fonctionnant avec le circuit d'alimentation décrit, se compose ( voir figures 2 et 3 ) d'un cône 51 au centre duquel débouche le gicleur 52 au travers du disque déflecteur 53 d'accrochage de flamme.The burner, operating with the supply circuit described, consists (see FIGS. 2 and 3) of a cone 51 at the center of which opens the nozzle 52 through the deflector disc 53 for catching the flame.

Le gicleur 52 est disposé sur la ligne porte-gicleur 54 et comporte par ailleurs un clapet 63 et un ressort taré à 19 bars¡64. L'allumage est assuré par l'électrode 55 alimentée par un transformateur haute tension 56, une cellule photorésistante 78 étant prévue pour le contrôle de la flamme.The nozzle 52 is disposed on the nozzle holder line 54 and furthermore comprises a valve 63 and a spring calibrated at 19 bars ¡ 64. The ignition is provided by the electrode 55 supplied by a high voltage transformer 56, a photoresist cell 78 being provided for flame control.

Le circuit d'alimentation en fluide entre le flexible 34 d'aspiration du combustible et le flexible 42 de retour du combustible comprend la pompe 60 et l'électrovanne 57, cette pompe 60 étant entraînée par la liaison 73 à partir du moteur 75 qui entraîne également la turbine 74. La liaison entre la pompe 60 et le gicleur 52 comporte le ballon réchauffeur 67 pourvu d'une résistance de réchauffage du combustible 66 et d'un calorifugeage 65. Ce ballon comporte également un filtre micro-mailles 68 pour l'alimentation du gicleur, un thermostat 69 pour la régulation de la température du combustible et un thermomètre 70 pour le contrôle de la température de ce combustible.The fluid supply circuit between the fuel suction hose 34 and the fuel return hose 42 comprises the pump 60 and the solenoid valve 57, this pump 60 being driven by the link 73 from the motor 75 which drives also the turbine 74. The connection between the pump 60 and the nozzle 52 comprises the heating tank 67 provided with a fuel heating resistor 66 and a thermal insulation 65. This tank also includes a micro-mesh filter 68 for the power supply to the nozzle, a thermostat 69 for regulating the temperature of the fuel and a thermometer 70 for controlling the temperature of this fuel.

La purge du circuit de combustible du brûleur est assurée par la vis 71, tandis que la vis 72 assure le réglage de la pression de la pompe.The purge of the burner fuel circuit is ensured by the screw 71, while the screw 72 ensures the adjustment of the pump pressure.

La mise en service du brûleur est assurée par l'interrupteur 77 tandis que le boîtier électronique 76 assure le contrôle du cycle de fonctionnement.The burner is put into service by the switch 77 while the electronic unit 76 ensures the control of the function cycle ment.

Le fonctionnement de ce brûleur alimenté par le circuit de la figure 1, est le suivant.The operation of this burner supplied by the circuit of FIG. 1 is as follows.

Au premier temps, le réchauffage du combustible dans le ballon réchauffeur 67 est assuré par la résistance 66. Le thermostat est réglé pour se déclencher à une température d'au moins 100° et, de préférence, 110° et le contrôle de la montée en température du combustible est assuré par le thermomètre 70. A ce stade, le combustible est au repos.At first, the heating of the fuel in the heating tank 67 is ensured by the resistor 66. The thermostat is set to trigger at a temperature of at least 100 ° and, preferably, 110 ° and the control of the rise in fuel temperature is ensured by the thermometer 70. At this stage, the fuel is at rest.

Le deuxième temps de fonctionnement est déclenché lorsque le thermostat 69 constate que la température du combustible a atteint la valeur affichée. Ce thermostat 69 commande alors le démarrage du moteur électrique 75 par l'intermédiaire du boîtier électronique 76. Le moteur 75 entraîne alors la turbine 74 pendant la période de préventilation qui est d'une durée de 20 secondes, ainsi que la pompe 60 qui aspire le combustible par le flexible 34 et le refoule dans le ballon réchauffeur 67 où il est constamment maintenu en température. Le combustible en circulation passe alors au travers du filtre micromail- les 68 pour être épuré des derniers résidus et traverse la ligne porte gicleur 54 qui est fermée pour retourner au bassin de stockage 26 par l'intermédiaire du flexible de retour 42 et de l'électrovanne 57 restée ouverte.The second operating time is triggered when the thermostat 69 finds that the fuel temperature has reached the displayed value. This thermostat 69 then controls the starting of the electric motor 75 via the electronic unit 76. The motor 75 then drives the turbine 74 during the pre-purging period which is 20 seconds long, as well as the pump 60 which sucks the fuel through the hose 34 and discharges it into the heating tank 67 where it is constantly maintained at temperature. The fuel in circulation then passes through the micromail filter 68 to be purified of the last residues and crosses the nozzle holder line 54 which is closed to return to the storage tank 26 via the return hose 42 and the solenoid valve 57 remained open.

La pression du combustible en circulation est de l'ordre de 16 bars.The pressure of the fuel in circulation is of the order of 16 bars.

A la fin de cette période de préventilation de 20 secondes, les électrodes 55 sont alimentées et commence alors le troisième temps de fonctionnement où est assurée la pulvérisation du combustible.At the end of this 20 second pre-ventilation period, the electrodes 55 are supplied with power and then the third operating time begins when the fuel is sprayed.

Pour cela, le boîtier électronique 76 commande la fermeture de l'électrovanne 57. Ce blocage du circuit du combustible entraîne une élévation de pression jusqu'à 21 bars et commande alors l'ouverture de la ligne porte gicleur 54 par l'action du combustible sur le clapet 63 qui comprime le ressort 64 taré à 19 bars.For this, the electronic unit 76 commands the closing of the solenoid valve 57. This blocking of the fuel circuit causes a pressure rise up to 21 bars and then controls the opening of the nozzle holder line 54 by the action of the fuel on the valve 63 which compresses the spring 64 calibrated to 19 bars.

Le réglage du débit d'air s'effectue par ouverture ou fermeture progressive du volet 58.The air flow is adjusted by gradually opening or closing the flap 58.

Le fonctionnement correct de cette installation est assuré par la décantation du combustible dans le bassin 18, alors que ce combustible est chauffé par la résistance chauffante 20, ce combustible décanté étant amené par le trop-plein 30 dans le bassin de stockage 26 à niveau constant. Le combustible ainsi préparé est alors amené au brûleur 32, ce brûleur assurant une circulation du fluide à pression élevée ( supérieure à 19 bars En outre, la pompe 60 est déterminée pour assurer un débit au moins deux fois supérieur à la consommation du combustible par le brûleur, ce combustible amené étant porté à une température élevée ( de l'ordre de 110° ) ce qui contribue avec la pression importante de ce fluide à assurer le fonctionnement du brûleur tandis que le combustible en excédant est ramené à cette température élevée dans le bassin de stockage 26.The correct functioning of this installation is ensured by the decantation of the fuel in the tank 18, while this fuel is heated by the heating resistor 20, this decanted fuel being brought by the overflow 30 into the storage tank 26 at constant level . The fuel thus prepared is then brought to the burner 32, this burner ensuring a circulation of the fluid at high pressure (greater than 19 bars. In addition, the pump 60 is determined to ensure a flow rate at least twice greater than the consumption of the fuel by the burner, this supplied fuel being brought to a high temperature (of the order of 110 °) which contributes with the high pressure of this fluid to ensure the operation of the burner while the excess fuel is brought back to this high temperature in the storage tank 26.

Il demeure bien entendu que cette invention n'est pas limitée à l'exemple de réalisation décrit et représenté, mais qu'elle en englobe toutes les variantes.It remains to be understood that this invention is not limited to the embodiment described and shown, but that it encompasses all variants thereof.

En particulier, il y a lieu de prévoir, suivant l'importance des puissances calorifiques, un ou plusieurs bacs 18 de décantation successifs ainsi qu'un ou plusieurs bacs de stockage.In particular, it is necessary to provide, depending on the importance of the calorific powers, one or more successive settling tanks 18 as well as one or more storage tanks.
