Abstract

The burner for burning a gaseous fuel is designed to produce an annular stream (1) of a gas containing oxygen and to generate a swirling motion in this stream (1). The burner also has a system to provide a central stream (4) of fuel which is directed to the surface of the combustion tunnel mouth. An additional central stream of fuel (5) in the form of a gas containing oxygen is supplied to the first fuel stream (4) in the zone lying outside the supply plane. This second stream of fuel has an oxygen content which lies between 1 and 25 percent of the oxygen content of the gas flowing in the annular stream (1).

Description

L'invention concerne les procédés de combustion d'un combustible et les dispositifs pour leur mise en oeuvre et a notamment pour objet les procédés de combustion d'un combUstible gazeux et les brûleurs pour leur mise en oeuvre. The invention relates to the methods of combustion of a fuel and the devices for their implementation and in particular relates to the methods of combustion of a gaseous fuel and the burners for their implementation.

Le procédé de combustion d'un combustible gazeux et le brûleur pour sa mise en oeuvre peuvent être utilisés pour le chauffage des fours a chauffer, des fou-rs thermiques ainsi que d'autres installations thermotechniques. The combustion process of a gaseous fuel and the burner for its implementation can be used for the heating of furnaces to be heated, thermal furnaces and other thermotechnical installations.

La combustion du combustible gazeux dans une torche ouverte de brûleurs à flamme laminaire ou dans une torche demi-ouvert de brûleurs a embouchure conique assure un chauffage regulier des articles, un régime hydraulique favorable des installations et la souplesse de la commande. The combustion of gaseous fuel in an open torch of laminar flame burners or in a half-open torch of burners with conical mouth ensures regular heating of the articles, a favorable hydraulic regime of the installations and the flexibility of the control.

On connaît bien un procédé de combustion d'un combustible gazeux (voir, par exemple, Erinov A.E.,Soroka B.E. A process for the combustion of a gaseous fuel is well known (see, for example, Erinov A.E., Soroka B.E.

"Ratsionalnye metody szhigania gazovogo topliva v nagrevatelnykh pechakh" ("Méthodes rationnelles de combustion de combustible gazeux dans des fours à chauffer"), Kiev, "Tekhnika ", 1970, pp. 182-215) consistant a amener un courant annulaire de gaz contenant de l'oxygène préalablement mis en tourbillon vers la surface d'une embouchure toroida- le d'un tunnel de brûleur et un courant central de combustible. La combustion du combustible se produit alors dans une torche ouverte."Ratsionalnye metody szhigania gazovogo topliva v nagrevatelnykh pechakh" ("Rational methods of combustion of gaseous fuel in heating ovens"), Kiev, "Tekhnika", 1970, pp. 182-215) of bringing an annular stream of oxygen-containing gas previously swirled to the surface of a toroidal mouth of a burner tunnel and a central stream of fuel. The combustion of the fuel then takes place in an open torch.

Le courant recirculant de produits issus de la combustion depuis l'atmosphère du volume intérieur d'une installation dans le volume intérieur de l'embouchure suivant son axe, produits qui font office de stabilisateur de la combustion, joue un rôle essentiel dans la conservation de l'état stable d'une torche ouverte. Toutefois, les produits de recyclage servent de source d'inflammation et ne stabilisent la torche du brûleur que dans des conditions déterminées, en particulier quand la temperature est suffisamment haute et la teneur en pourcentage du gaz combustible en oxygène est élevée.A une baisse du niveau thermique d'une install-ation entrainant une diminution de la tempéra ture du courant recirculant de produits de combustion depuis l'atmosphère du volume intérieur, il est indispensable d'augmenter la teneur des produits de combustion en oxydant, par exemple en aspirant l'air ambiant. Dans des installations fonctionnant aux basses températures, des fours thermiques dans lesquels on n'utilise pas l'aspiration de l'air ambiant, les conditions susmentionnées de l'inflammation et de la stabilisation d'une torche d'un brûleur ne sont pas respectées. Pour cette raison, il est impossible de brûler un combustible dans une torche ouverte dans les installations fonctionnant à des températures basses. The recirculating current of combustion products from the atmosphere of the interior volume of a facility in the interior volume of the mouthpiece along its axis, products that act as combustion stabilizers, plays an essential role in the conservation of the steady state of an open torch. However, the recycled products serve as an ignition source and stabilize the burner torch only under certain conditions, in particular when the temperature is high enough and the percentage content of the combustible oxygen gas is high. thermal level of an installation causing a reduction in the temperature of the recirculating current of combustion products from the atmosphere of the interior volume, it is essential to increase the content of the combustion products by oxidizing, for example by sucking the 'ambiant air. In installations operating at low temperatures, thermal ovens in which the suction of ambient air is not used, the above-mentioned conditions for the ignition and stabilization of a torch of a burner are not observed . For this reason, it is impossible to burn fuel in an open torch in installations operating at low temperatures.

On connaît bien un brûleur destiné à la mise en oeuvre d'un procédé de combustion d'un combustible gazeux (voir, par exemple, Erinov A.E., Soroka B.E.. "Ratsionalnye metody szhigania gazovogo topliva v nagrevatelnykh pechakh" (Methodes rationnelles de combustion de combustible gazeux dans des fours à chauffer) Kiev, "Tekhnika", 1970, p.183) comportant un corps pourvu d'un tourbillonneur et se rac- cordant par son ouverture de sartie à une embouchure toroi- dale d'un tunnel de brûleur. Un tuyau à gaz est loge dans le corps coaxialement à celui-ci. Une buse est montée sur son ouverture de sortie et est orientee coaxialement audit corps.Le brûleur connu mettant en oeuvre ce procédé de combustion du combustible gazeux ne peut fonctionner de maniere stable que dans les installations fonctionnant aux hautes températures. Dans les installations fonctionnant aux basses temperatures, il ne peut fonctionner qu'a une teneur elevée en oxydant de l'atmosphère du volume intérieur des installations. Si cette condition n'est pas respectee, des régimes pulsatoires de combustion dans ce brûleur qui perturbent un travail stable, ont lieu. A burner is well known for the implementation of a process for the combustion of a gaseous fuel (see, for example, Erinov AE, Soroka BE. "Ratsionalnye metody szhigania gazovogo topliva v nagrevatelnykh pechakh" (Rational methods of combustion of gaseous fuel in furnaces to be heated) Kiev, "Tekhnika", 1970, p.183) comprising a body provided with a vortex and connected by its sartie opening to a toroidal mouth of a burner tunnel . A gas pipe is housed in the body coaxial therewith. A nozzle is mounted on its outlet opening and is oriented coaxially to said body. The known burner implementing this gaseous fuel combustion process can only operate stably in installations operating at high temperatures. In installations operating at low temperatures, it can only operate at a high oxidizing content from the atmosphere of the interior volume of the installations. If this condition is not respected, pulsating combustion regimes in this burner which disturb stable work take place.

On s'est donc propos de mettre au point un procedé de combustion de combustible gaeux et un brûleur pour la mise en oeuvre de ce procédé dans lequel l'amenée du gaz oxygené vers l'embouchure du tunnel de bruleur assurerait l'élévation de la stabilisation de la combustion lors de la combustion du combustible en régime d'une torche ouverte. It has therefore been proposed to develop a method for the combustion of cheerful fuel and a burner for the implementation of this method in which the supply of oxygenated gas towards the mouth of the burner tunnel would ensure the elevation of the stabilization of the combustion during the combustion of the fuel in the regime of an open torch.

Ce problème est résolu du fait qu'un procédé de combustion d'un combustible gazeux consistant à amener un courant annulaire de gaz oxygéné préalablement -mis en tourbillon et un courant central de combustible vers la surface d'une embouchure du tunnel d'un brûleur, est caractérise, selon l'invention, en ce qu'on amène, dans la zone située en dehors des limites du plan de l'amenée du courant central de combustible, un courant central complémentaire de gaz oxygéné, dont la teneur en oxygène est de 1 Z à 25 Z la quantité d'oxygène présente dans le courant de gaz oxygene préalablement mis en tourbillon. This problem is solved by the fact that a method of combustion of a gaseous fuel consisting in bringing an annular stream of oxygenated gas previously - put in a vortex and a central stream of fuel towards the surface of a mouth of the tunnel of a burner , is characterized, according to the invention, in that one brings, in the zone situated outside the limits of the plane of the supply of the central fuel stream, a complementary central stream of oxygenated gas, the oxygen content of which is from 1 Z to 25 Z the quantity of oxygen present in the stream of oxygen gas previously put in a vortex.

Le probleme est résolu aussi du fait qu'un bruleur mettant en oeuvre en procédé de combustion du combustible gazeux comportant un corps pourvu d'un tourbillonneur et se raccordant par son ouverture de sortie à une embouchure du tunnel du brûleur, un tuyau à gaz logé dans le corps, une buse etant montée sur l'ouverture de sortie dudit tuyau coaxialement au corps, est caractérisé, selon l'invention en ce que l:e brûleur est muni en ou-tre, d'un dispositif pour l'amenée de gaz oxygéné, disposé en dehors des limites de la buse du tuyau à gaz. The problem is also solved by the fact that a burner using a gaseous fuel combustion process comprising a body provided with a swirler and connected by its outlet opening to a mouth of the burner tunnel, a gas pipe housed in the body, a nozzle being mounted on the outlet opening of said pipe coaxially with the body, is characterized, according to the invention in that the burner is provided in addition with a device for supplying oxygenated gas, disposed outside the limits of the gas pipe nozzle.

I1 est avantageux que, dans le but de simplifier- la construction du brûleur, le moyen d'amenée de gaz oxygéné soit exécuté sous la forme d'un tuyau disposé coaxiabement au corps et que l'ouverture de sortie dudit tuyau soit disposée en dehors de la buse du tuyau à gaz. It is advantageous that, in order to simplify the construction of the burner, the means for supplying oxygenated gas is executed in the form of a pipe arranged coaxially to the body and that the outlet opening of said pipe is arranged outside. from the gas pipe nozzle.

Le procédé revendique de combustion du combustible gazeux et le brûleur réalisant ce procéde permettent de brûler le combustible dans des torches ouvertes et demiouvertes des installations de chauffage de différents types y compris dans des installations fonctionnant aux basses temperatures en utilisant l'atmosphère du volume intérieur, dont la teneur en oxygène est faible.  The claimed process for combustion of gaseous fuel and the burner carrying out this process make it possible to burn the fuel in open and half-open torches of heating installations of different types including in installations operating at low temperatures using the atmosphere of the interior volume, with a low oxygen content.

En utilisant le procéde decrit de combustion du combustible gazeux et le brûleur pour sa mise en oeuvre on élargit le domaine de l'utilisation des brûleurs à torches ouvertes et demi-ouvertes, on diminue les bruits produits par le fonctionnement des brûleurs et on élève la stabilité du fonctionnement et la fiabilité du fonctionnement. By using the described procedure for combustion of gaseous fuel and the burner for its implementation, the field of use of open and half-open torch burners is widened, the noises produced by the operation of the burners are reduced and the operational stability and operational reliability.

L'invention sera mieux comprise et d'autres buts, details et avantages de celle-ci apparaitront mieux à la lumière de la description explicative qui va suivre d'un mode de réalisation donné uniquement à titre d'exemple non limitatif, avec références à un dessin unique non limitatif dans lequel est illustre en coupe partielle longitudinale, un brûleur mettant en oeuvre le procéde revendiqué de combustion d'un combustible gazeux, selon l'invention. The invention will be better understood and other objects, details and advantages thereof will appear better in the light of the explanatory description which follows of an embodiment given solely by way of nonlimiting example, with references to a single nonlimiting drawing in which is illustrated in partial longitudinal section, a burner implementing the claimed method of combustion of a gaseous fuel, according to the invention.

Le procede de combustion du combustible gazeux consiste en ce qui suit. The gaseous fuel combustion method consists of the following.

Un courant annulaire 1 de gaz oxygéné prealablement mis en tourbillon est amene sur la surface de l'embouchure 2 du tunnel d'un brûleur 3. Un courant central 4 de combustible est amené à la surface de l'embouchure 2 du tunnel de brûleur 3. Complémentairement, on amene dans la zone disposee en dehors du plan de l'amenée du courant cen-tral 4 du combustible, un courant central 5 de gaz oxygené dans lequel la quantité d'oxygene est de 1 Z à 25 %.la quantité d'oxygène présente dans le courant annulaire de gaz oxygéné- préalablement mis en tourbillon. Ce courant central 5 de gaz oxygéne empêche le courant 6 de produits de combustion recirculants de pénétrer dans la zone saturée de combustible dans laquelle le courant annulaire 1 de gaz oxygéné préalablement mis en tourbillon t le courant 4 de combustible interagit avec le courant 6 de produits de combustion recirculants et sature également ladite zone d'un oxydant complémentaire ce qui contribue à un allumage stable du courant 7 du mélange combustible-gaz oxygené.  An annular stream 1 of oxygenated gas previously swirled is brought to the surface of the mouth 2 of the burner tunnel 3. A central stream 4 of fuel is brought to the surface of the mouth 2 of the burner tunnel 3 In addition, the central current 4 of the fuel, a central current 5 of oxygenated gas in which the quantity of oxygen is from 1% to 25%, is brought into the area provided outside the supply plane. of oxygen present in the annular stream of oxygenated gas - previously put in a vortex. This central stream 5 of oxygenated gas prevents the stream 6 of recirculating combustion products from entering the saturated fuel zone in which the annular stream 1 of oxygenated gas previously swirled t the stream 4 of fuel interacts with the stream 6 of products of recirculating combustion and also saturates said zone with a complementary oxidant which contributes to a stable ignition of the stream 7 of the fuel-oxygenated gas mixture.

C'zest ainsi qu'on maintient separé de manière stable un courant 8 de produits de combustion, qu'on effectue la combustion stable du combustible independamment des condi
tions thermiques et de la quantité d'oxydant libre dans
l'espace utile d'une installation.It is thus that a stream 8 of combustion products is kept stably separated, that stable fuel combustion is carried out regardless of the conditions.
thermal ions and the amount of free oxidant in
the useful space of an installation.

Les limites de la teneur quantitative d'oxydant amené dans le courant central complementaire 5 de gaz oxygéné, sont definies en partant des faits suivants. L'amenee du courant central complémentaire 5 de gaz oxygéne dans lequel la quantité d'oxygene est inférieure à 1 Z de la quantité d'oxygene contenue dans le courant annulaire 1 de gaz oxygéné prealablement mis en tourbillon vers la zone dans laquelle le courant 7 du mélange combustible-gaz oxygéne interagit avec le courant 6 de produits de combustion recirculants, ne modifie pas la natune du processus qui se produit. The limits of the quantitative content of oxidant supplied to the additional central stream of oxygenated gas are defined on the basis of the following facts. The supply of the complementary central current 5 of oxygenated gas in which the quantity of oxygen is less than 1 Z of the quantity of oxygen contained in the annular current 1 of oxygenated gas previously swirled towards the zone in which the current 7 of the oxygen-fuel gas mixture interacts with the stream 6 of recirculating combustion products, does not modify the nature of the process that occurs.

L'augmentation de la quantité d'oxygène dans le courant central complémentaire 5 de gaz oxygene au-dessus de 25 Z de la quantite d'oxygene presente dans le courant annulaire 1 de gaz oxygène préalablement mis en tourbillon provoque un refroidissement de la zone de stabilisation de l'inflammation du combustible et change la direction du deplacement du courant 6 de produits de combustion recirculants et du courant 8 de produits de combustion. The increase in the quantity of oxygen in the complementary central stream 5 of oxygen gas above 25 Z of the quantity of oxygen present in the annular stream 1 of oxygen gas previously put in vortex causes a cooling of the zone of stabilizes the ignition of the fuel and changes the direction of movement of the stream 6 of recirculating combustion products and of the stream 8 of combustion products.

Le brûleur destiné à mettre en oeuvre le procedé de combustion du combustible gazeux comporte un corps 9 pourvu d'un tourbillonneur 10-, fixé sur la surface latérale du corps 9. L'ouverture de sortie 11 du corps 9 se raccorde à l'embouchure 2 du tunnel du brûleur 3. Le brûleur comprend un tuyau à gaz 12, logé dans le corps 9. Une buse 14 est montée dans l'orifice de sortie 13 dudit tuyau à gaz coaxialement au corps. Un moyen d'amenée de gaz oxygéne constitué par un tuyau 15, dont l'ouverture de sortie 16 est logee en dehors de la buse 14 dans la zone du début de stabilisation de l'inflammation de la torche, est monté coaxialement au corps 9. The burner intended to carry out the process of combustion of the gaseous fuel comprises a body 9 provided with a swirl 10-, fixed on the lateral surface of the body 9. The outlet opening 11 of the body 9 is connected to the mouth 2 of the burner tunnel 3. The burner comprises a gas pipe 12, housed in the body 9. A nozzle 14 is mounted in the outlet orifice 13 of said gas pipe coaxially with the body. A means of supplying oxygenated gas constituted by a pipe 15, the outlet opening 16 of which is housed outside the nozzle 14 in the area of the start of stabilization of the ignition of the torch, is mounted coaxially with the body 9 .

Le brûleur mettant en oeuvre le procédé de combustion du combustible gazeux fonctionne de la manière suivante. The burner implementing the gaseous fuel combustion method operates in the following manner.

Le courant de gaz oxygene parvient dans le tourbillonneur 10 du corps 9. Le courant de gaz oxygéné est alors mis en tourbillon par le tourbillonneur 10. Le courant central 4 de combustible debouche de la buse 14 dans le courant annulaire 1 de gaz oxygéne préalablement mis en tourbillon. En conséquence, il se forme un mélange combustible-gaz oxygené en aval du plan de la buse 14. A une certaine distance par rapport à la buse 14, on introduit, suivant l'axe du corps 9 depuis le tuyau 15, le courant 5 de gaz oxygéné à la rencontre du courant 6 des produits de combustion recirculants. Ce courant empeche le courant 6 de produits de combustion recirculants de pénétrer suivant l'axe du corps 9 et sature en oxydant la zone d'interaction du courant 7 de melange combustible-gaz oxygéné et du courant 6 de produits de combustion recirculants. On crée ainsi les conditions pour la présence constante de la zone de stabilisation de l'inflammation et on garantit par cela meme l'indépendance du caractère de fonctionnement du brûleur vis-à-vis des conditions thermiques règnant dans l'espace utile d'une installation de chauffage. The stream of oxygen gas arrives in the swirl 10 of the body 9. The stream of oxygenated gas is then put in a swirl by the swirl 10. The central stream 4 of fuel opens out from the nozzle 14 into the annular stream 1 of oxygen gas previously put in a vortex. Consequently, a fuel-oxygenated gas mixture is formed downstream of the plane of the nozzle 14. At a certain distance from the nozzle 14, the current 5 is introduced along the axis of the body 9 from the pipe 15. of oxygenated gas meeting the current 6 of the recirculating combustion products. This current prevents the current 6 of recirculating combustion products from penetrating along the axis of the body 9 and saturates by oxidizing the interaction zone of the current 7 of fuel-oxygenated gas mixture and of the current 6 of recirculating combustion products. This creates the conditions for the constant presence of the ignition stabilization zone and thereby guarantees the independence of the operating character of the burner from the thermal conditions prevailing in the useful space of a heating installation.

L'application du procede de combustion d'un combustible gazeux et du brûleur pour sa mise en oeuvre dans des fours de chauffage et des fours thermiques assurent une combustion stable d'un combustible gazeux en régime d'une torche ouverte et, par conséquent, un chauffage regulier et faiblement oxydant des pieces à chauffer ce qui contribue à l'élévation de la qualité des pièces chauffées et à la réduction des pertes du métal dont elles sont fa briquets.  The application of the method of combustion of a gaseous fuel and of the burner for its implementation in heating ovens and thermal ovens ensure stable combustion of a gaseous fuel in the regime of an open torch and, consequently, regular and weakly oxidizing heating of the parts to be heated, which contributes to raising the quality of the heated parts and reducing the losses of the metal from which they are made.
