La fig. 7 montre un detail en coupe ä plus Brande echelle suivant la ligne 7-7 de la fig. 5; La fig. 8 est une coupe suivant la ligne 8-8 de la fig. 6. _ L'appareil represente dans les fig. 1 ä, 4 comporte une chambre ä gaz C ä 1'interieür dune piece cylindrique 2, qui est fermee au sommet et ä la Partie inferieure, la paroi la- t6rala de la chambre ä gaz presentant une serie de trous d'injection 2e qui sont prdvus tres pres les uns des autres saivant une ligne helicoidale. La piece 2 est munie ä sa Partie inferieure d'un prolongement lateral crelzx 2a qui communique avec la chambre C, et dopt la paroi supgrieure presente pres de son ex- tr6mit6 externe une ouverture reliee par un tuyau 4b ä un tube de radlange 4. fig. 7 shows a larger scale sectional detail along line 7-7 of FIG. 5; fig. 8 is a section along line 8-8 of FIG. 6. The apparatus shown in Figs. 1 to 4 has a gas chamber C inside a cylindrical piece 2, which is closed at the top and at the bottom, the side wall of the gas chamber presenting a series of injection holes 2e which are provided very close to each other in a helical line. Part 2 is provided at its lower part with a lateral extension creelzx 2a which communicates with chamber C, and has the upper wall present near its outer end an opening connected by a pipe 4b to a radlange tube 4.

Autour de la chambre ä gaz C, c'est-ä-dire ä 1'exterieur de la pike 2, se trouve un tube .-az6ificateur 1 en forme de serpentin dont les spires ont un diamUre interne legerement superieur au diamkre externe de la paroi la terale de la pike 2 et sont placks en regard des trous 2e de fa@on que les jets de ga.z sor- tant par res trous, en brillant, chauffent res spires pour produire la gazeification du com- bustible dans 1e serpentin gazeifieateur. Around the gas chamber C, that is to say outside the pike 2, there is a serpentine-shaped gasifier tube 1 whose turns have an internal diameter slightly greater than the external diameter of the gas chamber. wall the side of the pike 2 and are placed opposite the holes 2e so that the jets of gas emerging through the holes, shining, heat the turns to produce the gasification of the fuel in the first coil gasifier.

La pike 2 presente exterieurement des nervures radiales 2b qui servent ä espacer convenablement les spires du serpentin ga.z6i- ficateur de la paroi lat6rale de la chambre ä ga.z et maintiennent res spires en Position convenable par rapport ä rette chambre. Le serpentin gazeificateur 1 est . supporte d'un cotd de la pike 2 par 1e prolongement 2a et de 1'autre par une console 29 fixee ä ladite pike comme represente en fig. d. Spike 2 has radial ribs 2b on the outside which serve to properly space the turns of the gasifier coil from the side wall of the gas chamber and maintain the turns in proper position with respect to this chamber. Gasifier coil 1 is . supported on one side of pike 2 by extension 2a and on the other by a bracket 29 fixed to said pike as shown in FIG. d.

L'extremite de la. spire la plus hasse du serpentin ga.zeificateur 1 fait corps avec un 616ment tubulaire 1d dispose verticalement et au-dessous du serpentin gazeificaleur et relie ä un robinet de r6glage <B>19</B> pour 1'arrivee du kerosene fourni par un tuyaii Ih venant du reservoir ä kerosene non represente. The extremity of the. the lowest turn of the gasifier coil 1 is integral with a tubular element 1d arranged vertically and below the gasifier coil and connected to a control valve <B>19</B> for the arrival of kerosene supplied by a Ih pipe coming from the kerosene tank not shown.

De preference, 1e kerosiene est delivre du reservoir par 1'action d'air comprim6 qui 1e refoule dans 1'eldment-tubulaire 1d quand an ouvre 1e robinet 7.g. Preferably, the kerosene is delivered from the reservoir by the action of compressed air which forces it back into the tubular element 1d when the tap 7.g is opened.

L'extremite superieure du tube ga.z6ifica- teur 1 est relik ä un coude 1i dont la section transversale decroit vers 1'extremite supd- rieure ä laquelle est visse un ajutage gicleur 1' qui est constitue par un el6ment tubulaire de falble lon.gueur 6 ferme ä sön extremite su- perieure et dont la paroi laterale presente au- d.essous de rette extremite superieure fermee un Petit orifice 1 , formant Bouche de gicla.ge, debitant 1e gaz engendre dans 1e serpentin gazeificateur 1. Cet ajutage gicleur est peu sujet ä s'obstruer etant donne que 1e carbone, susceptible d'etre entraine par les gaz arri- vant du tube gazeificateur 1 serait emprisonn6 dans la chambre 1v de 1'ajutage au-dessus de 1'orifice 1 et n'obturerait pas cet orifice de giclage. The upper end of the gasifier tube 1 is connected to an elbow 1i whose cross section decreases towards the upper end to which is screwed a nozzle nozzle 1' which is constituted by a tubular element of low length. length 6 closes at its upper end and the side wall of which has, below its closed upper end, a small orifice 1, forming a nozzle mouth, debiting the first gas generated in the gasifier coil 1. This nozzle nozzle is little subject to clogging since the carbon, likely to be entrained by the gases arriving from the gasifier tube 1, would be trapped in the chamber 1v of the nozzle above the orifice 1 and would not block not that squirt orifice.

Le RTI ID="0002.0273" WI="6" HE="4" LX="1359" LY="625"> gaz est delivre horizontalement par Porifice 1 de 1'ajutage gicleur dann 1'extre- mitA ouverte d'un tube de melange 4 et de fair etant aspire par rette extremite ouverte, penetre dans ce tube prA-s de 1'ajuta.ge gicleur pour se melanger avee 1e gaz traversant le tube de melange, les melanges gazeux Uant conduits de ce tube ä 1'pndroit d'utilisation. The RTI ID="0002.0273" WI="6" HE="4" LX="1359" LY="625"> gas is delivered horizontally through Port 1 of the nozzle nozzle into the open end A of a mixing tube 4 and being sucked in by its open end, enters this tube close to the nozzle to mix with the first gas passing through the mixing tube, the gas mixtures being led from this tube to 1 'right to use.

Le tube de melange 4 se relie par un rac- cord en T, 4a au tube 4x qui 1e prolonge, ce raccord 4x recevant 1'extremit6 superieure du tuyau 4b, qui peut servir en meme temps ä supporter 1e tube de melange 4 sur la pike 2, les organes etant disposes de faqon que los axes du tuyau 4b et de 1a. chambre C soient verticaux et de faQon que Faxe du tube de melange 4 soit horizontal. The mixing tube 4 is connected by a T-fitting 4a to the 4x tube which extends it, this 4x fitting receiving the upper end of the pipe 4b, which can serve at the same time to support the mixing tube 4 on the pike 2, the bodies being arranged so that the axes of the pipe 4b and 1a. chamber C are vertical and so that Faxe of the mixing tube 4 is horizontal.

La majeure Partie des gaz est conduite par un tuy au 4d du tube de melange A un four ä chauffer des rivets 5, comme represente ä. la fig. 1. Une autre Partie des gaz passe du tube de melange par 1e tuy au 4b dans 1a, cham- bre ä gaz C et, s'echapparit par les ouver- tures 2e de rette cha.mbre, brüle ä 1'exterieur de ladite cha.mbre pour chauffer 1e tube Olazei- ficateur 1 en y entretenant la produetion de gaz. Most of the gases are conducted through a pipe at 4d from the mixing tube A to a rivet heating furnace 5, as shown at. fig. 1. Another part of the gases passes from the mixing tube through pipe 4b into the gas chamber C and, escaping through the openings 2e of this chamber, burns outside the said chamber. chamber for heating the oleazeifier tube 1 while maintaining the production of gas therein.

Le tube gazeificateur 1 e.st enferme Gans une bogte G qui est supportee par 1a Partie superieure de la pike 2 et dont les parois verticales entourent ce tube et se prolongent jusqu'au-dessous de la chambre C, comme re- pr6sent6 par les dessins. Cette enveloppe presente sur un röte une ouverture plaede pres de 1'a.juta.ge gieleur 1' en vue de permettre de diriger la flamme d'un chalumeau ou dune lampe ä souder vers 1e tube gazeifica- teur 1 dans 1e but de chauffer ce tuyau au debut et d'amorcer la production de gaz. Tout autrc dispositif approprie -pourrait eire em- hloy6 pour chauffier 1e tube gazeificateur 1 au debüt de 1'operation. The gasifier tube 1 is enclosed in a box G which is supported by the upper part of the pike 2 and whose vertical walls surround this tube and extend to below the chamber C, as represented by the drawings. This envelope has on one side an opening placed close to the gasifier tube 1' in order to allow the flame of a torch or a blowtorch to be directed towards the gasifier tube 1 in order to heat the gasifier. this pipe at the beginning and to initiate the production of gas. Any other suitable device could be employed to heat the gasifier tube 1 at the start of the operation.

La construction decrite est remarquable par la forme en serpentin helicoidal du tube gazeificateur. La Partie superieure - de la chambre ä gaz C est cylindrique, et an peut de la sorte Bonner une Brande longueur au tube gazeificateur 1. Da.ns la construction re- pr6sentee, 1e kerosene est en pratique trans- forme en gaz (au lieu d'etre simplement ou principalement vaporise) et Fon obtient -un Brand volume de-gaz combustible pour nne qiiantite donnee de kerosene. En outre, ce gaz se m61ange facilement avec une graiide quan- tite d'air et 1e m61ange de gaz et d'air de qualite parfaite ainsi obtenu produit une cha- leur plus intense qu'un melange d'hiüle va- porisee et d'air. The described construction is remarkable for the helical serpentine shape of the gasifier tube. The upper part of the gas chamber C is cylindrical, and in this way it can extend a brand length to the gasifier tube 1. In the construction shown, the kerosene is in practice converted into gas (instead of to be simply or mainly vaporized) and Fon obtains a Brand volume of combustible gas for a given amount of kerosene. Moreover, this gas mixes easily with a large quantity of air and the mixture of gas and air of perfect quality thus obtained produces a more intense heat than a mixture of vaporized oil and oil. 'air.

Dans 1e brüleur represente aux fig. 1 ä 3, oü 1e raccord en T 4a du tube de melange est relie ä la chambre ä gaz, si du kerosene liquide venait ä etre refoule ä travers 1'aju- tage-gicleur 1' dans 1e tube de melange, ce li quide descendrait ä 'travers ce raccord dann la- dite chambre et remplirait celle-ei en empe- chant ainsi le fonctionnement convenable de 1'appareil jusqu'ä ce que ce liquide ait ete kar- t4 ou brüle. In the first burner represented in FIGS. 1 to 3, where the T-fitting 4a of the mixing tube is connected to the gas chamber, if liquid kerosene should be forced through the nozzle 1' into the mixing tube, this liquid would descend through this connection into the said chamber and would fill the latter, thereby preventing the proper functioning of the apparatus until this liquid has been emptied or burned.

Pour empecher ce remplissage de la cham- bre ä gaz par du liquide, an peut se servir de 1a forme d'execution representee par les fig. 5 ä 8, etablie de maniere ä empecher dune fagon efficace 1'introduction de kero- sAne liquide dann la chambre ä gaz et ä per inettre en outre de regler tres exactement et suivant qu'on 1e desire 1'admission de gaz ä ladite chambre. To prevent this filling of the gas chamber with liquid, the embodiment shown in FIGS. 5 to 8, so designed as to effectively prevent the introduction of liquid kerosene into the gas chamber and to further enable the admission of gas to said chamber to be regulated very exactly and as desired. .

Comme 1e montrent les fig. 5 ä 8, le raccord 4a taraude ä ses extremites opposees en vue de sa jonction avec lfa tube de melange 4 et 1e tube de prolongement 4x presente, dass sa Partie superieure, un orifice 4 (fig. 7 et 8). per- mettant au gaz de passer Jans. un conduit 4c forme dass la paroi du raccord, s'etendant partiellement autoirr de celui-ei et communi- quant avec une tubulure 4d dost l'extremite inferieure est vissee sirr 1'extremite superieure du tuyau 4b; la tubulure 4d ne communique avec 1'interieur du raccord 4a que par 1'inter- mediaire du conduit 46. As shown in Figs. 5 to 8, the connector 4a taps at its opposite ends for its junction with the mixing tube 4 and the first extension tube 4x has, in its upper part, an orifice 4 (Figs. 7 and 8). allowing the gas to pass Jans. a duct 4c formed in the wall of the fitting, extending partially around the latter and communicating with a pipe 4d where the lower end is screwed onto the upper end of the pipe 4b; the tubing 4d only communicates with the interior of the connector 4a via the conduit 46.

Comme represente dans les fig. 7 et 8, 1'orifice 4a prevu pour 1e Passage du gaz se trouve ä la Partie superieure du raccord *4a. Il s'ensuit que si du kerosene liquide venait ä etre projete dans 1e tube de melange, ce li quide ne pourrait couler dans 1e tuyau 4 et penetrer dans laRTI ID="0003.0275" WI="13" HE="4"LX="1278" LY="557"> chambre ä gaz-C. Si du ke- rosene liquide venait ä etre refoule dans le tube de melange 4, il ne pourrait que se ren- dre au four 5 dans lequel il n'aurait aucun effet nuisible, serait rapidement briile et n'ar- reterait ou ne retarderait en aucune fagon 1e f onetionnement du brüleur. As represented in Figs. 7 and 8, the orifice 4a provided for the passage of gas is located at the upper part of the fitting *4a. It follows that if liquid kerosene were to be projected into the mixing tube, this liquid could not flow into the pipe 4 and enter the RTI ID="0003.0275" WI="13" HE="4"LX= "1278" LY="557"> gas chamber-C. If liquid kerosene were to be forced back into the mixing tube 4, it could only go to the furnace 5 where it would have no deleterious effect, would burn rapidly and would not stop or delay the process. in any way the operation of the burner.

Dans 1e but de regler la quantite de gaz pouvant passer du tube de m61ange 4 dann la chambre ä gaz C, des moyens de reglage sont prevus pour faire vagier la section de Passage de 1'orifice 4 et 1e volume , de gaz Passant e, travers cet orifice et 1e tuyau 4b. Ces moyens comportent un pointeau 40 (fig. 7) moste de fagon ä pouvoir coulisser dass une chamke 4w' formee dass 1e raccord ä 1a Partie superieure de celui-ei et la Position de ce poiuteau peut etre reglee (comme indique par les lignes pointillees de la fig. 7) de fagon ä regler la quantite de gaz Passant du tube de m61ange dass la chambre ä gaz C. Le pointeau est maintenu dass la chambre 4v' par un cou- vercle visse 4u et la tige 4s dudit pointeau traverse un presse-etoupe 4. Ces moyens de reglage peuvent etre de toute autre construc- tion appropriee pourvu qu'ils permettent -de regler la quantite de gaz Passant ä travers 1'ouverture 4 de fagon ä maintenir 1e serpen- tin gazeificateur 1 ä la temperature donnant les meilleurs resultats. In order to adjust the quantity of gas that can pass from the mixing tube 4 into the gas chamber C, adjustment means are provided to vary the passage section of the orifice 4 and the first volume of passing gas, through this hole and the first pipe 4b. These means comprise a needle 40 (fig. 7) moste so as to be able to slide in a chamke 4w' formed in the first connection at the upper part of the latter and the position of this needle can be adjusted (as indicated by the dotted lines of Fig. 7) so as to regulate the quantity of gas passing from the mixing tube into the gas chamber C. stuffing box 4. These adjustment means may be of any other appropriate construction provided that they make it possible to adjust the quantity of gas passing through the opening 4 so as to maintain the gasifying coil 1 at the temperature giving the best results.
