Abstract
The present invention relates to an energy-efficient cooker or hotplate using gasified liquid fuel and having a wickless burner. The liquid fuel in the tank is pressurised and the pressure is maintained in order to provide the flow rate required for the carburetion of the liquid fuel, resulting in the complete combustion thereof. The delivery tube is placed inside the tank, in the central axis of the tank. Said tube is provided, at the bottom end thereof, with a strainer which acts as a filter through which the vaporised liquid fuel rises from the central shutoff valve which, in turn, adjusts the flow of fuel, and thus adjusts the flames as required. The continuous vaporisation of the liquid fuel is ensured by the burner using the heat generated by the combustion. The device offers an alternative to cookers and hotplates using gas or other fuels. Since lamp oil can be obtained cheaply in most developing countries and households can produce their own biofuel, everyone can use the modern and hygienic energy-efficient cookers and hotplates of the invention to preserve our ecosystem.

La présente invention n'utilise que des combustibles liquides comme le pétrole lampant, l'alcool, l'essence et la plupart des carburants et biocarburants liquides. The present invention uses only liquid fuels such as kerosene, alcohol, gasoline and most liquid fuels and biofuels.
Le terme biocarburant désigne des combustibles d'origine végétale. On parle aussi d'agrocarburant. On distingue deux grandes classes en terme de biocarburant : - Les premières : Les alcools, bioéthanol (éthanol) obtenus à partir de cultures riches en sucre ou en amidon (sorgho, canne à sucre, betterave, manioc, etc.), ils peuvent être utilisés à 100 % en
remplacement du pétrole lampant comme combustible dans la présente cuisinière éco énergétique avec des rendements éloquents The term biofuel refers to fuels of plant origin. We also talk about agrofuel. There are two main classes in terms of biofuel: - The first: Alcohols, bioethanol (ethanol) obtained from crops rich in sugar or starch (sorghum, sugar cane, beetroot, cassava, etc.), they can be 100% used in replacement of kerosene as a fuel in this eco-energetic stove with impressive yields
- Les deuxièmes : Les huiles, le biogazole, le diester, obtenues à partir des graines oléagineuses (colza, soja, tournesol, Jatropha, etc) : La fluidification de l'huile permet d'obtenir ce que certains appellent le Biogazole, d'autres le diester, d'autres encore le dieselbi. Toutes ces marques commerciales recouvrent un seul et même produit : les esters méthyliques d'huile qui peuvent être utilisés à partir de 50 à 100% en lieu et place du pétrole lampant comme combustible pour la cuisinière éco énergétique avec des rendements intéressants. - The second: The oils, the biodiesel, the diester, obtained from oilseeds (rapeseed, soybean, sunflower, Jatropha, etc): The fluidification of the oil makes it possible to obtain what some call the Biogazole, of others the diester, still others the dieselbi. All these trademarks include a single product: methyl esters of oil that can be used from 50 to 100% instead of kerosene as a fuel for the energy efficient cooker with attractive yields.
On sait que l'emploi comme combustible pour des cuisinières et réchauds du pétrole lampant et ses homologues liquides ne sont pas développés jusqu'à présent comme on pouvait s'y attendre, en raison de leur accessibilité, de leur pouvoir calorifique et de leurs avantages sécuritaires pour certains. Ce faible développement peut être attribué particulièrement au fait que les cuisinières à pétrole et autres combustibles liquides actuellement en service sont pour la plupart à mèches et elles ont fait preuve d'un rendement relativement bas et dégagent souvent une odeur qui rend peu agréable le séjour dans les locaux où ils sont installés du fait de leur combustion incomplète. It is known that the use as fuel for stoves and kerosene stoves and its liquid counterparts are not developed so far as would be expected, because of their accessibility, their calorific value and their advantages. safe for some. This low development can be attributed in particular to the fact that the kerosene kettles and other liquid fuels currently in use are mostly wicks and they have shown a relatively low yield and often give off an odor that makes it uncomfortable to stay in the premises where they are installed because of their incomplete combustion.
L'expérience a montré que la combustion dans ces réchauds et cuisinières peut être rendue difficilement complète tant que le combustible liquide est conduit au brûleur par l'intermédiaire de mèches. Experience has shown that the combustion in these stoves and stoves can be made difficult to complete as long as the liquid fuel is fed to the burner via wicks.
L'invention a pour but de fournir un réchaud et une cuisinière à combustible liquide avec brûleur sans mèche procurant une combustion complète avec un rendement maximal. The object of the invention is to provide a stove and a liquid fuel cooker with a non-wicking burner providing complete combustion with maximum efficiency.
Conformément à l'invention, ce but est atteint avec un réchaud ou une cuisinière comprenant une pompe ou un compresseur qui pompe l'air dans le réservoir contenant du combustible liquide à travers un clapet sans retour. La pression acquise par compression demeure présente dans le réservoir et assure le débit nécessaire à sa carburation qui engendre sa combustion complète. Cette pression acquise peut être obtenue par le niveau de gravité du combustible liquide d'alimentation. According to the invention, this object is achieved with a stove or a range comprising a pump or a compressor which pumps air into the tank containing liquid fuel through a valve without return. The pressure acquired by compression remains present in the tank and ensures the flow rate necessary for its carburation which generates its complete combustion. This acquired pressure can be obtained by the level of gravity of the liquid feed fuel.
La vaporisation continue du combustible liquide est par la suite assurée par le brûleur au moyen de la chaleur engendrée par la combustion. Cette vaporisation se passe dans une zone prédéfinie où la température et la pression atteignent souvent des valeurs telles que les chaînes de carburants liquides sont transformées en des molécules gazeuses de type C1, C2, C3 et C4 par des réactions
dont le craquage. Les gaz obtenus sont aussitôt utilisés par le brûleur pour entretenir la combustion. The continuous vaporization of the liquid fuel is subsequently ensured by the burner by means of the heat generated by the combustion. This vaporization takes place in a predefined zone where the temperature and the pressure often reach values such that the liquid fuel chains are transformed into gas molecules of the C1, C2, C3 and C4 type by reaction reactions. including cracking. The gases obtained are immediately used by the burner to maintain combustion.
A l'intérieur, et dans l'axe central du réservoir, est placé le tube de refoulement muni à son extrémité inférieure d'une crépine qui sert de filtre par où monte le combustible liquide vaporisé après la vanne centrale d'arrêt qui sert à son tour de régulatrice de débit du combustible, donc de régulatrice à volonté des flammes. Dans les variantes à plus d'un feu, le tube de refoulement fait monter le combustible vers les conduits à travers un répartiteur dont le nombre est fonction du nombre de foyers. Inside, and in the central axis of the tank, is placed the discharge tube provided at its lower end with a strainer which serves as a filter by which vaporized liquid fuel is mounted after the central shut-off valve which serves to its regulator turn of the fuel flow, therefore regulator at will of the flames. In variants with more than one fire, the discharge tube causes the fuel to flow to the ducts through a distributor whose number depends on the number of households.
Ce réservoir dispose d'une entrée servant au remplissage du combustible. Elle est pourvue d'un bouchon et d'un régulateur de remplissage. Une autre entrée munie de vanne permet de vider l'air du réservoir à volonté. La pression interne du réservoir est mesurable par un manomètre. This tank has an inlet for filling the fuel. It is provided with a plug and a filling regulator. Another inlet equipped with a valve makes it possible to empty the air of the tank at will. The internal pressure of the tank is measurable by a manometer.
Le dispositif de gazéification proprement dit est constitué d'une ou plusieurs sources de chaleur primaire de toute sorte disposées dans la zone de préchauffage prévue spécialement à cet effet et dans laquelle (zone) le combustible comprimé dans les tubulaires est transformé en gaz par effet thermique avant sa sortie dans le gicleur. The actual gasification device consists of one or more primary heat sources of any kind arranged in the preheating zone provided for this purpose and in which (zone) the compressed fuel in the tubulars is converted into gas by thermal effect. before leaving it in the jet.
Le dispositif conçu conformément à l'invention possède plusieurs avantages. En effet, c'est un dispositif alternatif aux cuisinières et réchauds à gaz ou autres. Le pétrole lampant se trouvant bon marché dans la plupart des pays en développement et la possibilité pour les ménages de produire eux-mêmes leur biocarburant peut permettre à tous d'utiliser les cuisinières et réchauds modernes et hygiéniques selon l'invention. Par conséquent, l'utilisation du bois de chauffe et du charbon de bois peut être revue considérablement à la baisse et entraînera une préservation de notre écosystème. The device designed according to the invention has several advantages. Indeed, it is an alternative device to gas stoves and stoves or others. Since kerosene is inexpensive in most developing countries, and the ability of households to produce their own biofuel can enable everyone to use modern and hygienic stoves and stoves according to the invention. As a result, the use of firewood and charcoal can be significantly reduced and will result in the preservation of our ecosystem.
Par ailleurs, l'invention fourni un dispositif plus sécuritaire que les dispositifs utilisant un stock de combustibles gazeux en C1 , C2, C3 et C4 plus volatiles, plus explosifs et donc plus dangéreux. Moreover, the invention provides a safer device than devices using a stock of gaseous fuels C1, C2, C3 and C4 more volatile, more explosive and therefore more dangerous.
Afin d'exposer plus clairement toutes les caractéristiques de la cuisinière éco énergétique, une variante, celle à un feu est décrite ci-après, ce qui synthétise au mieux la compréhension et les fonctionnements parmi toutes celles qui sont possibles, cela à titre d'exemple non limitatif, avec référence aux dessins joints. In order to more clearly set out all the characteristics of the energy-efficient stove, a variant, that of a fire, is described below, which best summarizes the understanding and the functioning of all those that are possible, as non-limiting example, with reference to the accompanying drawings.

Le brûleur assure le réchauffement recyclé du pétrole lampant à pulvériser qui constitue ainsi un élément de catalyse pour la gazéification au moyen de la chaleur engendrée par les sources thermiques pouvant être graduées avec la plus grande précision en ce qui concerne le dégagement de chaleur qu'elle peut produire et dont le rendement est par conséquent constamment uniforme. The burner ensures the recycled heating of the kerosene to be sprayed, which thus constitutes a catalytic element for the gasification by means of the heat generated by the heat sources which can be graduated with the greatest precision with regard to the release of heat which it can produce and whose performance is therefore consistently uniform.
Cette caractéristique peut-être considérée comme d'une importance capitale en ce qui concerne la transformation régulière du combustible qui passe ainsi de l'état liquide à l'état gazeux, par un changement d'état physique, car c'est de cette transformation que dépend, en substance, la combustion totale et , par ricochet, l'élimination des phénomènes de cracking et décomposition du
combustible liquide lui-même sous l'effet de la chaleur , phénomène qui provoque, comme on le sait, le changement d'état du combustible initial. This characteristic can be regarded as of paramount importance with regard to the regular transformation of the fuel which thus passes from the liquid state to the gaseous state, by a change of physical state, since it is this transformation. that depends, in essence, the total combustion and, in turn, the elimination of the phenomena of cracking and decomposition of liquid fuel itself under the effect of heat, a phenomenon which causes, as is known, the change of state of the initial fuel.
Dans la cuisinière éco énergétique, le pétrole lampant liquide est soumis à une pression convenable capable d'être ajusté à volonté lorsque la pression normale de fonctionnement tend à diminuer. In the energy-efficient cooker, the liquid lamp oil is subjected to a suitable pressure that can be adjusted at will when the normal operating pressure tends to decrease.
L'idée de faire brûler le pétrole lampant, les biocarburants, agro carburants, carburant vert" et "carburant végétal" de première, et de future génération, et les paraffines liquides, gazéifiés avec brûleur sans mèche n'avait jamais trouvé jusqu'à maintenant d'application très décisive dans le domaine des cuisinières avec un rendement sensiblement meilleur par rapport à celui des cuisinières à pétrole à mèche et avec la garantie d'une combustion parfaite complètement dépourvue de résidus fuligineux. The idea of burning kerosene, biofuels, agro-fuels, green fuel "and" vegetable fuel "first, and future generation, and liquid paraffins, gasified with burner without wick had never found now of very decisive application in the field of stoves with a significantly better performance compared to that of the stoves with oil wick and with the guarantee of a perfect combustion completely devoid of sooty residues.
Selon une forme de réalisation préférentielle, la cuisinière selon l'invention peut être pourvue de plusieurs foyers dont les variantes les plus simplifiées et les plus usitées sont celles de un à quatre feux. According to a preferred embodiment, the stove according to the invention can be provided with several fireplaces whose most simplified and most used variants are those of one to four fires.
D'autres encore peuvent s'ajouter à ceux déjà mentionnées en vue de, soit mieux maîtriser le modèle dans son fonctionnement, soit perfectionner le dispositif selon le modèle dont le bon agencement des différents éléments constitutifs représente le principe et son bon fonctionnement.
Still others may be added to those already mentioned in order to either better control the model in its operation or to perfect the device according to the model, the good arrangement of the various constituent elements represents the principle and its proper operation.
