Description

Brüleur gaz6ifieateur Whulle combustible, et autres combustibles Hquides peu volatils. Uobjet de la pr6sente inv6ni#i & n est un brüleur gazgifieateur d'huile combustible et autres combustibles liquides peu -volatils; ce brüleur comprenant une chambre dans la- quelle le liquide d6borde pour y Atre vaporis6. Burner gasifier Whulle fuel, and other low volatility liquid fuels. The object of the present invention is a gasifier burner for fuel oil and other low-volatile liquid fuels; this burner comprising a chamber into which the liquid overflows to y be vaporized.

L'invention se r6,f#re prineipalement aux moyens pour faciliter et intensifier le r6- ellauffa-,e d'une calotte formant la chambre de vaporisation, par la combustion mAme, et ä des moyens pour perfeetionner la vaporisa- tion da liquide. Dans le brüleur suivant Pin- vention le liquide ne vient jamais en contaet avee 1,1 ealotte de mani6re que toute possibi- lit6 d'inerustations, enerassage, ete. dus ä la dkomposition du liquide, soit glimink. The invention relates mainly to the means for facilitating and intensifying the heating of a cap forming the vaporization chamber, by the same combustion, and ä means for improve the vaporization of liquid. In the burner according to the invention the liquid never comes into contact with the 1.1 ealotte so that any possibility of inerustations, clogging, et. due ä to the decomposition of the liquid, or glimink.

Le fonetionnement du pr6sent brüleur est en cons6quence plus sür que celui de brüleurs eonnus dudit "enre et il ne demande qu'une manutention bien plus r#duite. The operation of the present burner is therefore safer than that of known burners of the said type and it requires much less handling.

Le dessin annexA repr6sente, ä titre d'exemple, trois formes d'exkution du brü- leur suivant Finvention. The appended drawing shows, ä by way of example, three embodiments of the burner according to the invention.

1 (fig. 1) Usigne un plateau ou cuvette au centre duquel arrive un tube 3 se prolon- geant au-dessus du phateau en un bee 2 du- quel l'huile d6borde sans pression sur le pla- teau. Sur le plateau s'appuie le bord d'un corps ereux ou ealotte 4 pourvu de pieds 5' qui le maintiennent quelque peu soulev6, de maniAre ä former, entre le bord et le plateau un passage annulaire Y'. Par ce passage s'6- chappent les vapeurs combustibles qui se for- ment dans le corps creux ou ealotte 4 lors- que l'huile d6borde du bee 2, par suite de la haute tempgra-ture qui rAgne dans la ealotte. Le r6chaufiage de celle-ei est artifieiel au commencement de la combustion et il est con- tinu6 ensuite par eifet de la combustion m9me. 1 (fig. 1) Machines a plate or basin in the center of which comes a tube 3 extending above the phateau in a bee 2 from which the oil overflows without pressure on the plate. On the plate rests the edge of a erous body or ealotte 4 provided with 5' legs which keep it somewhat raised6, in a way ä to form, between the edge and the plate an annular passage Y'. Through this passage escape the combustible vapors which form in the hollow body or ealotte 4 when the oil overflows from the bee 2, as a result of the high tempgra-ture which prevails in the ealotte. The reheating of the latter is artificial at the beginning of the combustion and it is then continued by the effect of the combustion itself.

Sur le plateau s'appuie un anneau 6 pr6- sentant des trous 6' pour le passage de Fair de combustion; ces trous gtant pratiqu6s sui- vant des rangs cireulaires superpos6s et ayant un ealibre diminuant du bas en haut, en vue de diminuer la quantitg d'air introduite sui- vant la diminution du gaz non brül6 dans des zones successives. Si los trous Maient de ealibre uniforme, la combustion, so faisant en des zones de plus en plus pauvres en gaz, deviendrait bruyante, tandis qu#avee los trous de ealibre diminuant elle est parfaitement sileneieuse. On the tray rests a ring 6 with holes 6' for the passage of Combustion air; these holes being made in superimposed circular rows and having a diameter decreasing from bottom to top, with a view to reducing the quantity of air introduced following the reduction of the unburned gas in successive zones. If the holes were of uniform caliber, the combustion, taking place in zones increasingly poor in gas, would become noisy, whereas with the holes of decreasing caliber it is perfectly silent.

Sur Fanneau 6 est enfi16 un anneau coni- quo 8, qui faeilite le raccordement du brä- leur ä la bouclie 10 de l'appareil utüisateur. On the ring 6 there is finally a conical ring 8, which facilitates the connection of the burner ä the loop 10 of the user device.

La calotte 4 est pourvue d'un rebord ou saillie 9 qui, Mant Mcli# par la flamme, com- munique au corps 4 la chaleur n6cessaire ä la vaporisation du coinbustible; dans cette premi & e forme d'exkution. le rebord 4' est solidaire, du corps de la ealotte, en vue d'ob- tenir une transmission plus parfaite et com- plAte de la chaleur. The cap 4 is provided with a rim or projection 9 which, Mant Mcli# by the flame, communicates to the body 4 the heat necessary ä for the vaporization of the fuel; in this first form of exkution. the rim 4' is integral with the body of the shell, with a view to obtaining a more perfect and complete transmission of heat.

La sortie des gaz ou des vapeurs combus- tibles selfeetuant par le bord infirieur de la ealotte, et le combustible liquide ne ve- nant jamais en contaet avee los parois de la ealotte, on 6vite tout d6pöt d'incrustatious dü ä la condensation ou ä, la d6coinposition du combustible. The exit of combustible gases or vapors killing by the lower edge of the shell, and the liquid fuel never coming into contact with the walls of the shell, any deposit of incrustation due to ä< is avoided. /B> condensation or ä, decomposition of the fuel.

Aussi los gaz ou vapeurs sortent par la partie la plus large de la ealotte, ce qui per- met d'6tablir une ouverture de sortie tr#s basse, pour laminer los gaz, en vue d'en favo- riser le mdlange avee Pair. Also the gases or vapors come out through the widest part of the shell, which makes it possible to establish a very low outlet opening, to laminate the gases, with a view to favoring their mixing with the air. .

Los vapeurs so forment dans la ealotte hors du contaet avee Pair et so rencontrent avee celui-ei seulement au moment ou elles brülent, 6vitant ainsi toute condensation. The vapors are formed in the shell out of contact with the air and are encountered with the latter only when they are burning, thus avoiding any condensation.

Dans un ioyer de liaute puissa.nce (fig. 2), Pair n'arriverait pas en quantit6 suffisante par le manclion perfor6,6, ä eause de l'inten- sitg de la vaporisation du combustible, de maniAre quo la combustion so produirait dans uDe ambiance trap rinhe en gaz. Cet incon- v6nient est 61imin6 par le fait que la ealotte conique est munie d'un canal central 4" qui s'appuie sur le plateau 1 et qui est pourvu en liaut dun c'hapeiu 12' muni de perfora- tions. Avee cette disposition, une certaine quantitd d'air additionnel p6n6tre par Pouver- ture centrale 11 du plateau 1, et sort par los trous du chapeau. 1-52' 6panouissant et alimen- taut la flamme en air comburant. Ce dispchsitif est comp16t6 par une cuvette infirieure 25 dans laquelle sont recueillies los gouttes de combustible en exc#s. Ce d6pöt est aspir6 en grande partie par l'air d'alimenta- tion, et il est brül6 avec los vapeurs combus- Übles. In a high power furnace (fig. 2), the air would not arrive in sufficient quantity through the perforated sleeve6,6, ä because of the intensity of the vaporization of the fuel, in such a way that combustion would take place in a gas-free atmosphere. This drawback is eliminated by the fact that the conical shell is fitted with a 4" central channel which rests on the plate 1 and which is provided in connection with a 12' cap provided with With this arrangement, a certain amount of additional air enters through the central opening 11 of the tray 1, and exits through the holes in the bonnet. -52" expands and supplies the flame with combustive air. This device is completed by a lower basin 25 in which the excess fuel drops are collected. This deposit is largely aspirated by the supply air, and is burned with the combustible vapours.

Pour des loyers de puissance moyenne, le brüleur peut Atre 6tabli suivant la forme d'exkution rel)r6sent6e ä la fig. 3. Dans ce eas la calotte est tronconique, comme dans le cas de la fig. 1 et pourvue d'une saillie 40 et d'un canal 4". L'air qui parcourt ce dernier sort dans la cliambre de, combustion au travers des trous 12", pere#s en partie sous le bord 4' et en partie dans l'6paisseur mAme de ce bord. For rents of average power, the burner can be established according to the form of execution rel) represented ä in fig. 3. In this case the cap is tapered, as in the case of fig. 1 and provided with a 40 protrusion and a 4" channel. The air passing through the latter exits into the combustion chamber through holes 12 ", pere#s partly under the 4' edge and partly in the very thickness of this edge.

Dans los trois formes d'exkution d6eri- tes, en peut pr6voir des moyens pour r6gler la hauteur de la calotte sur le plateau, ces moyens pouvant Atre des vis, petites colonnes d'appui, etc. In the three typical execution forms, means can be provided for adjusting the height of the cap on the plate, these means being able to be screws, small support columns, etc.
