Description
Procede perfectionne ponr produire une atmosphere chaude, <B>et</B> generateur pour <B>la</B> mise en Oeuvre de ce procede. La presente Invention se rapporte ä un procede perfectionne pour pyoduire une at- mosphere chaude, notamment une atmosphere chaude respirable, convenant ä 1'alimentation de Brands bätiments, et ä un generateur pour la mise en aeuvre de ce procede. Improved process for producing a hot atmosphere, <B>and</B> generator for <B>the</B> implementation of this process. The present invention relates to an improved method for producing a hot atmosphere, in particular a breathable hot atmosphere, suitable for supplying buildings, and to a generator for carrying out this method.
Il est de pratique courante aujourd'hui d'elever la temperatiire d'air ä im certain degre de chaleur desire, pour Palimentation de bätiments, tels que des groupes de biueaux, en brillant im combustdble Jans un fourneau et transfer%nt la chaleur ainsi generge ä Fair cl'alimentatdon ä Faide d'un echangeur de cha- leur, Fair ainsi ehauffe etant alors envoye dann les bätiments. It is common practice today to raise the temperature of the air to a certain degree of heat desired, for the supply of buildings, such as groups of stoves, by burning non-combustible in a stove and thus transferring the heat. Generates the food with the aid of a heat exchanger, the heat thus heated being then sent to the buildings.
Un tel Systeme presente plusieurs d6s-avan- tages. Ainsi, 1e transfert de chaleur dans 1'echan.geur n'est en general pas tont ä Fait efficace; ce serait plus efficace et moins cA- teux de faire passer les produits de combus- tion directement dans les bätiments, mais jus- qu'ä present, an n'a pu 1e faire, car ces pro- cluits etaient. toujours nocifs. Le caractere relativ ement toxique de ces produits de com- bustion provient du fait que 1e combustible briile dann 1e fourneau, Pest imparfaitement. Des lors, au lieu de poiivoir employer lesdits produits de combustion directement comme moyen de chauffage, il faut les faire passer ä travers un gchangeur de chaleur et les envoyer ensuite comme rebut 'a une chominee. Such a system has several disadvantages. Thus, the heat transfer in the exchanger is generally not very efficient; it would be more efficient and less costly to pass the products of combustion directly into the buildings, but so far this has not been possible because these products were. always harmful. The relatively toxic character of these combustion products comes from the fact that the fuel burned in the stove is imperfectly burning. Therefore, instead of being able to use said combustion products directly as heating means, they have to be passed through a heat exchanger and then sent as waste to a chimney.
La. presente Invention permet de rendre les produits de combustion d'un Foyer propres ä etre employes comme atmosphere meme, de Sorte que Fechangeur de chaleur usuel et la cheminee deviennent superflus. The present invention makes it possible to render the products of combustion of a hearth suitable for use as the atmosphere itself, so that the usual heat exchanger and the chimney become superfluous.
Le pröcede selon l'invention est caracte ris6 en .ce que 1'on brüle un combustible avec de Pair, en produisant d'abord ime combus tion Primaire partielle, an brille ensuite avec de fair les produits de la combustion Primaire en prodiüsant une combustion secondaire sen siblement complete en presence d'un cataly seur d'oxy dation, de preference an ajoute encore de Pair aux produits de la combustion secondäire de fa@on ä fommer une atmosphere dune temperature entre des limites pr6d6ter minAes. Quant au generateur pour la mise en cenvre de ce procede, il comprend ime cham. bre de combustion Primaire avec entrges pour fair et 1e combustible et, faisant siüte ä cette chambre de eombustion Primaire et en com munication .avec eile, une chambre de com bustion secondaire avec entree drair et conte nant un catalyseur d'oxydation, ainsi que, en av al du catalyseur, une sortie pour les gaz produits. The process according to the invention is characterized in that a fuel is burned with air, first producing a partial Primary combustion, then burning with the products of the Primary combustion producing a partial combustion. secondary combustion substantially complete in the presence of an oxidation catalyst, preferably by adding further air to the secondary combustion products so as to form an atmosphere of a temperature between predetermined limits. As for the generator for the implementation of this process, it includes a chamber. Primary combustion chamber with air and fuel inlets and, adjacent to this Primary combustion chamber and in communication with it, a secondary combustion chamber with air inlet and containing an oxidation catalyst, as well as, downstream of the catalyst, an outlet for the gases produced.
La fonction du catalyseur d'oxydation est de favoriser la combustion secondaire,'de telle Sorte que les produits quittant 1e generateur soient eomplUement brüles, et en outre, soient propres ä etre respires. De pref4rence, il est prevu ime troisieine entree d'air dann 1e generateiir, entre 1e cata- lyseur et la sortie du generateur, par laquelle de Pair atmospherique peut etre ajoute de fa- @on contrölable aux produits de eombustion relativement chauds, de fa@on ä former une atmosphere finale ayant tonte temperature desiree. The function of the oxidation catalyst is to promote secondary combustion, so that the products leaving the generator are fully burned, and furthermore, are fit to breathe. Preferably, there is provided a third air inlet to the generator, between the catalyst and the generator outlet, through which atmospheric air can be controllably added to the relatively hot combustion products, thereby a final atmosphere having any desired temperature is formed.
0n deerira maintenant une forme d'exe- eution preferee du generateur pour la mise en aeuvre du proced#- selon Finvention, en reference au dessin schematique annexe, dans lequel: Fig. 1 est une vue en section axiale du generateur, et fig. 2 est ime section par la ligne II-II de fig.1. We will now describe a preferred embodiment of the generator for implementing the process according to the invention, with reference to the appended schematic drawing, in which: FIG. 1 is an axial sectional view of the generator, and fig. 2 is ime section by the line II-II of fig.1.
Le generateur represente est indique, de fa@on generale, par 10 et comprend une cham- bre de combustion primaire eylindrique 11, ayant une entree pour 1e combustible saus forme d'un brüleur contröle par une valve 13, dopt Fouverture est contrölable par un sole- noide 14. Autour du briileur 12 se trouve une ouverture 15 d'entree de Fair; 1'arrivee de celle-ei est contrölee par im registre 16, de telle manAre que 1a. combustion primaire dann la chambre 11 ne se fasse qu'incompletement. L'extremite de sortie de la chambre priinaire 11 est formee d'un manchon ou goulot de sec- tion transversale allant progressivement en decroissant, de Sorte que les produits de eom- bustion. primaire passent au travers, en pro- duisant un effet de trampe. L'air secondaire arrive autour de ce manchon par une ouver- ture 18; il est regle par un rejstre 19; de la Sorte, les produits de la combustion primaire sont soumis ä ime combustion secondaire dans une chambre secöndaire 20, disposee du cöte de sortie dudit manchon 17. En vue d'assurer que la combustion seeondaire soit complete, an a dispos4 dans la chambre 20 une Batterie de eatalyseurs d'oxydation 21, qui favorisent la combustion dans cette ehambre d'oxydation secondäire, de Sorte que des produits nocifs qui pourraient saus cela rester dann les gaz sortant de la chambre secondaire, sont eom- pletement oxydes et rendus inoffensifs pour la respiration. Par exemple, du monoxyde de carbone, qui pourrait rester dann les produits de la combustion secondaire, est, gräee aux catalyseurs d'oxydation, completement oxyde en dioxyde de carbone. The generator shown is indicated generally at 10 and comprises an eylindrical primary combustion chamber 11, having a fuel inlet in the form of a burner controlled by a valve 13, the opening of which is controllable by a solenoid 14. Around the burner 12 is an air inlet opening 15; the arrival of the latter is controlled by register 16, in such a way that 1a. primary combustion dann chamber 11 is done only incompletely. The outlet end of the primary chamber 11 is formed by a sleeve or neck of progressively decreasing cross-section, so that the combustion products. primary pass through, producing a tramp effect. The secondary air arrives around this sleeve through an opening 18; it is regulated by a rejster 19; In this way, the products of the primary combustion are subjected to a secondary combustion in a secondary chamber 20, arranged on the outlet side of said sleeve 17. In order to ensure that the secondary combustion is complete, an a a battery of oxidation catalysts 21, which promote combustion in this secondary oxidation chamber, so that harmful products which could otherwise remain in the gases leaving the secondary chamber, are completely oxidized and rendered harmless to breathing. For example, carbon monoxide, which might remain in the products of secondary combustion, is, due to oxidation catalysts, completely oxidized to carbon dioxide.
L'extremite de sortie de la chambre d'oxy- dation secondaire est aussl formee dun man- chon ou goulot 22 de section transversale allant en decroissant progressivement, de Sorte que les produits de la combustion secondaire passent au- travers en produisant aussi un effet de trampe. Autour du manchon 22 est disposee une tuyere de sortie 23, dans laquelle RTI ID="0002.0273" WI="14" HE="4" LX="1126" LY="807"> dAbouche un troisieme conduit d'arrivee d'air 24, contr814 par iui registre 25. De Pair atmospherique relativement froid est amene de fagon contrölable pour etre melange aux produits finals de combustion, lesquels etant tres chauds, doivent etre refroidis avant d'etre aptes ä etre utilises pour des buts tels que Pair de conditiönnement de bätiments. The outlet end of the secondary oxidation chamber is also formed of a sleeve or neck 22 of progressively decreasing cross-section, so that the products of the secondary combustion pass therethrough also producing an effect. tramp. Around the sleeve 22 is arranged an outlet nozzle 23, in which RTI ID="0002.0273" WI="14" HE="4" LX="1126" LY="807"> dAbouche a third inlet duct air 24, controlled by damper 25. Relatively cold atmospheric air is brought in in a controllable manner to be mixed with the final products of combustion, which being very hot, must be cooled before they are suitable for use for purposes such as conditioning of buildings.
L'air est fourni saus pression pour les trois arrivees d'air 15, 18 et 24, par im venti- lateur 26 envoyant Pair dann un distributelir 27, et actionne par un moteur electrique 28. Celiü-ei est alimente en courant dune source 29 ä travers un commutateur ä main 30. L'un des Pils d'amende du eourant au moteur eom- prend un interrupteur de circuit 31, eom- inande par un solenoide 32. Lorsque 1e foyer est mis en action, ie commutateur 30 et 1'interrupteur 31 sont tous deux fermes, de Sorte que 1e moteur 28 fonctionne. Quand 1e g4nerateur a atteint 1e point de pleine marehe, 1'energie cinetique des ga.z produits sortant par la tuyere 23 peut etre utilisee pour action- ner un generateur de courant 33 place dans 1e retrecissement de sortie de la tuyere 23. Le courant fourni par ce generateur est alors envoye au moteur 28, par les conduits A et B, en agissant Sur 1e commutateur 30 pour aetionner 1e ventilateur 26, en remplacement de la source de eourant 29. The air is supplied under pressure for the three air inlets 15, 18 and 24, by a fan 26 sending air into a distributor 27, and actuated by an electric motor 28. This is supplied with current from a source 29 through a hand switch 30. One of the motor current feeders includes a circuit switch 31 controlled by a solenoid 32. When the firebox is actuated, the switch 30 and switch 31 are both closed, so that motor 28 operates. When the generator has reached the full operating point, the kinetic energy of the produced gases exiting nozzle 23 can be used to drive a current generator 33 located in the outlet constriction of nozzle 23. The current supplied by this generator is then sent to the motor 28, through the ducts A and B, by acting on the first switch 30 to aetion the first fan 26, replacing the current source 29.
Dans Pappareil repr6sente, il est prevu un dispositif de seeurite ä Paide duquel 1a. fourniture de combustible et/ou d'air au gen6- rateur est automatiquement arretee si pour une raison qüelconque il reste des substances nuisibles dans les produits finals de com bustion. In the apparatus shown, there is provided a safety device with the aid of which 1a. The supply of fuel and/or air to the generator is automatically stopped if for any reason harmful substances remain in the final combustion products.
La proportion de ces substances délétères est fonction de la différence entre les tempé ratures régnant de part et d'autre du cata lyseur 21 dans la chambre de combustion secondaire. Cette différence est mesurée à l'aide d'une paire de thermocouples 34 et 35, les courants développés dans ceux-ci étant appliqués à un galvanomètre différentiel 36 d'un genre connu, ayant deux cadres mobiles et un. secteur oscillant 37, qui est déplacé angul.airement d'une quantité et dans un sens déterminés par la grandeur et le sens de la différence 'entre les deux courants appliqués au galvanomètre. Un palpeur 38, appuyant contre le bord incurvé du secteur 37, est monté sur un pivot fixe 39 et porte une extension vers l'arrière 40 poussée de faon permanente vers le haut par un ressort 41, de manière que la paire de contacts 42 et 43 sont maintenus normalement séparés. Ces contacts sont en circuit avec le solénoïde 32. En 44 est une came qui tourne à. une vitesse uni forme, commandée par exemple par un mé canisme contrôlé par une pendule. La dispo sition est telle que, si la différence des tem pératures mesurées par les thermocouples reste entre des limites prédéterminées, le sec teur 37 reste en contact avec le tâteur 38, et dans ces conditions, quand la portion de plus grand diamètre de la came 44 presse contre le tâteur, les contacts 42 et 43 restent séparés parce que l'extrémité gauche du tâteur ne peut s'élever; mais si le secteur 37 se déplace dans un sens ou dans l'autre hors de contact avec le tâteur 38, chaque fois que la came tourne, elle soulève l'extrémité gauche du tâ- teur 38, et abaisse son extrémité de droite 40, à l'encontre de l'action du ressort 41, de sorte que le contact 42, 43 est fermé; le solénoïde 32 reçoit alors du courant, l'interrupteur 31 est ouvert, et le moteur 28 est privé de cou rant, de sorte que le ventilateur est arrêté. En même temps le solénoïde 14 est excité et feigne la valve d'alimentation en combustible 13. The proportion of these deleterious substances depends on the difference between the temperatures prevailing on either side of the catalyst 21 in the secondary combustion chamber. This difference is measured by means of a pair of thermocouples 34 and 35, the currents developed therein being applied to a differential galvanometer 36 of a known kind, having two movable frames and one. oscillating sector 37, which is moved angularly by an amount and in a direction determined by the magnitude and direction of the difference between the two currents applied to the galvanometer. A feeler 38, pressing against the curved edge of sector 37, is mounted on a fixed pivot 39 and carries a rearward extension 40 permanently urged upwards by a spring 41, so that the pair of contacts 42 and 43 are normally kept separate. These contacts are in circuit with solenoid 32. At 44 is a cam which rotates. a uniform speed, controlled for example by a mechanism controlled by a pendulum. The arrangement is such that, if the difference in temperatures measured by the thermocouples remains between predetermined limits, the sector 37 remains in contact with the feeler 38, and under these conditions, when the larger diameter portion of the cam 44 presses against the feeler, the contacts 42 and 43 remain separated because the left end of the feeler cannot rise; but if sector 37 moves in either direction out of contact with feeler 38, each time the cam rotates it raises the left end of feeler 38, and lowers its right end 40, against the action of the spring 41, so that the contact 42, 43 is closed; the solenoid 32 then receives current, the switch 31 is open, and the motor 28 is deprived of current, so that the fan is stopped. At the same time the solenoid 14 is energized and simulates the fuel supply valve 13.
Le combustible fourni au générateur peut être un hydrocarbure liquide, Le catalyseur d'oxydation peut être de tout genre connu ou convenable, par exemple du genre décrit au brevet français N 1018100, et dans ce cas la matière catalytique peut consister en une substance finement divisée choisie parmi les suivantes: platine, ruthé nium, palladium, argent,` cuivre, argent- chrome, cuivre-chrome, nickel et cobalt, ou un mélange de ces substances. Cette matière finement divisée est déposée sur une subs tance de base choisie entre les suivantes: oxyde d'aluminium, oxyde de magnésium, oxyde de béryllium, et oxyde de thorium, ou des mé langes de ces substances. Cette substance de base est portée par un support de porcelaine. The fuel supplied to the generator can be a liquid hydrocarbon, the oxidation catalyst can be of any known or suitable kind, for example of the kind described in French patent N 1018100, and in this case the catalytic material can consist of a finely divided substance selected from the following: platinum, ruthenium, palladium, silver, copper, silver-chromium, copper-chromium, nickel and cobalt, or a mixture of these substances. This finely divided material is deposited on a base substance chosen from the following: aluminum oxide, magnesium oxide, beryllium oxide, and thorium oxide, or mixtures of these substances. This basic substance is carried by a porcelain support.
Le poids de la substance catalysante est d'environ 5 % de celui de la substance de base, et le poids de la base elle-même est très faible comparé à celui du support. The weight of the catalyst substance is about 5% of that of the base substance, and the weight of the base itself is very low compared to that of the carrier.
On constatera que le procédé et l'appareil décrits présentent plusieurs avantages sur les systèmes connus. Par exemple, la combustion est poussée jusqu'à achèvement complet, de sorte que son efficacité est aussi élevée que possible, tandis que le catalyseur non seule ment assure cette combustion complète, mais encore contribue à éliminer toute substance délétère des produits de combustion. En outre, l'énergie cinétique des produits de combustion est utilisée pour la fourniture d'air sous pression au générateur, et, d'autre part, grâce à l'introduction d'air en aval du catalyseur, le volume et la température de l'atmosphère produite peuvent être amenés à toute valeur voulue. L'appareil est mis auto matiquement hors d'action si les produits de combustion, pour une raison quelconque, de viennent impropres à leur but. L'emploi d'échangeurs de chaleur et de cheminées est évité, de sorte que tout le système est à la fois efficace et économique. It will be seen that the described method and apparatus have several advantages over known systems. For example, the combustion is pushed to complete completion, so that its efficiency is as high as possible, while the catalyst not only ensures this complete combustion, but also helps to eliminate any deleterious substances from the products of combustion. In addition, the kinetic energy of the combustion products is used for the supply of pressurized air to the generator, and, on the other hand, thanks to the introduction of air downstream of the catalyst, the volume and temperature of the atmosphere produced can be brought to any desired value. The appliance is automatically put out of action if the products of combustion, for any reason, become unsuitable for their purpose. The use of heat exchangers and stacks is avoided, so the whole system is both efficient and economical.
