Description

Appareil pour 1e chauffage, ä Paide d'bydrocarbures liquides, de chaudieres tubulaires marines et de chaudieres cylindriques ä retour de flamme. Lobjet de la presente invention est un appareil pour le chauffage, ä 1'aide d'hydro- carbures liquides, par ex. du naphte, de chau- dieres tubulaires marines et de chaudieres cylindriques ä retour de flamme. Apparatus for heating, by means of liquid hydrocarbons, marine tubular boilers and cylindrical backfire boilers. The object of the present invention is an apparatus for heating, using liquid hydrocarbons, e.g. naphtha, marine tubular boilers and cylindrical flashback boilers.

Les appareils pulverisateurs d'hydrocar- bures connus jusqu'ici presentent de nombreux inconvenients, entre lesquels 1'on mentionne les suivants 1. Le lancement de la flamme en direc- tion longitudinale produit une remarquable perte de chaleur, inconvenient grave du fait que la plus grande Partie de 1'intensitd de la flamme est dirigee contre la paroi opposee de la chambre du foyer. . The hydrocarbon sprayers known up to now have many drawbacks, among which the following are mentioned: most of the flame intensity is directed against the opposite wall of the firebox. .

2. Ils ne permettent jamais d'obtenir une temperature. uniforme sur toute 1'dtendue de la chambre de chauffe, ce qui se traduit par de dangereüx coups de feu sur quelques Par ties du faisceau tubulaire. 2. They never get a temperature. uniform over the entire extent of the heating chamber, which translates into dangerous shots on some parts of the tube bundle.

3. Ils ne permettent jamais d'obtenir pen- dänt la combustion une dilatation uniforme des diffdrentes Parties de la chaudiere, ce qui produit une deterioration rapide de cette der- niere. L'appareil selon la presente invention ob- vie ä tour lesdits inconvenients et rdalise des importants avantages. Par exemple il peut fournir une chaleur intense dune fagon con- tinue et uniforme, ce qui donne pour rdsultat une rapide production de vapeur en quantites tres importantes et consequemment une rapide mise sous Pression de la chaudiere. 3. They never allow to obtain during combustion a uniform expansion of the different parts of the boiler, which produces a rapid deterioration of the latter. The apparatus according to the present invention obviates in turn said disadvantages and achieves important advantages. For example, it can supply intense heat in a continuous and uniform manner, which results in a rapid production of steam in very large quantities and consequently a rapid pressurization of the boiler.

Le dessin ci-annexe reprdsente deux formes - d'dx6cution de 1'objet de 1'invention donnees ä titre d'exemple. The attached drawing represents two forms - of execution of the object of the invention given by way of example.

La fig. 1 montre fapplication de deux appareils formant 1'objet de 1'invention ä une chaudiere du type Thornycroft, la paroi än- terieure de la chambre de chauffe etant en- levde et un desdits appareils (celui de droite) etant representd en coupe transversale. fig. 1 shows the application of two devices forming the object of the invention to a boiler of the Thornycroft type, the inner wall of the heating chamber being removed and one of the said devices (the one on the right) being represented in cross section.

La fig. 2 est une coupe suivant la ligne x-x de la fig. 1 et reprdsente un desdits appareils partiellement en coupe_ longitudinale mddiane. La fig. 3 represente, partielleinent, en coupe longitudinale mediane et ä echelle plus Brande, Pappareil formant Pobjet de 1'iriven- tion. fig. 2 is a section along line x-x of FIG. 1 and represents one of said devices partially in mid-longitudinal section. fig. 3 represents, partially, in median longitudinal section and on a larger scale, the apparatus forming the object of the invention.

Les fig. 4 et 5 sont des coupes res- pectivement suivant les lignes zv-ie et z-z de la fig. 3. Figs. 4 and 5 are sections respectively along the lines zv-ie and z-z of FIG. 3.

L'appareil comprend rin tube, coristitue de deux Parties 1 et 2 (fig. 2) en forme de gouttieres reliees ensemble dune fagon etanche ä Faide de vis de serrage 3. Dann 1e corps 1, 2 est loge un tube 4 ferme ä 1'exti-eniite interne et occuparit presque toute 1a loiigueur du corps cylindrique 1, 2. Cela a 1e but de constituer, entre le corps susdit et 1e tube 4, une chambre tubulaire 21 (fig. 5). Le tube 4 communique, ä Paide de petits tubes ra- diaux 13, avec 1e foy er 14. The device comprises a tube, consisting of two parts 1 and 2 (fig. 2) in the form of gutters connected together in a watertight fashion by means of clamping screws 3. In the first body 1, 2 is housed a tube 4 closed at 1 exti-eniite internal and occuparit almost all 1a loiigueur of the cylindrical body 1, 2. This has the first purpose of forming, between the aforesaid body and the first tube 4, a tubular chamber 21 (Fig. 5). The tube 4 communicates, by means of small radial tubes 13, with the hearth 14.

L'extremite posterieure du tobe 4 est ren- due solidaire d'un pivot creux 5 supporte par un coussinet 11 monte nur un support 12. The rear end of tube 4 is secured to a hollow pivot 5 supported by a bearing 11 mounted on a support 12.

Un arbre 22 pourvu dune bride 23 est fixe ä Faide de boulons 25 ä rine bride 24 de 1'extrernite anterieure du tobe 1, 2. La bride 23 est pourvue de trous 17 (fig. 7). Sur 1'arbre 22 est mont6e la roue dune tur- bine 6 renfei#mee Jans une boite cylindrique 7, des distributeurs 15, 16 sont pi-evus sur la boite 7 et par ces distributeurs 15, 16 Fhydrocarbure ä brüler est fourni sous Pres sion. La boite 7 est montee sur un Sup port 10. A shaft 22 provided with a flange 23 is fixed by means of bolts 25 to a flange 24 of the front end of the tube 1, 2. The flange 23 is provided with holes 17 (fig. 7). On the shaft 22 is mounted the wheel of a turbine 6 enclosed in a cylindrical box 7, distributors 15, 16 are seen on the box 7 and through these distributors 15, 16 the hydrocarbon to be burned is supplied under pressure. if we. Box 7 is mounted on a Support 10.

Le tube 1, 2 est inuni de renforcements 18 avec des trous radiaux 19 dont la section diminue de Pinterieur vers 1'exterieur. Les renforcemeiits sont eritoures de manchons cylindriques 20 de toile metallique ä mailles tres fines. Les marichons 20 ont un diametre plus grad que celui des renforcements 18 et sont pourvus ä leurs extremit6s de brides dirigees vers 1'iiiterierir. Le diametre de la lumiere de ces brides est egal ü celui du tube 1, 2. Cela permet de maintenir les manchons 20 r6gulierement ecartes de maniere ä etablir des chambres tubulaires autour des renforcements. The tube 1, 2 is provided with reinforcements 18 with radial holes 19 whose section decreases from the inside outwards. The reinforcements are made of cylindrical sleeves 20 of very fine mesh wire mesh. The sleeves 20 have a larger diameter than that of the reinforcements 18 and are provided at their ends with flanges directed towards the interior. The diameter of the opening of these flanges is equal to that of the tube 1, 2. This makes it possible to maintain the sleeves 20 regularly spaced apart so as to establish tubular chambers around the reinforcements.

L'appareil fonctionne de la maniere sui- vante: L'hydrocarbure est refou1e sous Pression au travers de distributeürs 15 et 16 (fig. 1) et par des lumieres 15' de la paroi plane de la boite 7, va actionner la rorie de la turbine 6. Celle-ci tournera et eiitrainera en rotation ]es Parties 1, 2 et 4. L'hydrocarbure, mele ä de Pair de carburation, remplira la boite 7 et au travers des trous 17 de la beide 23 Passera dans la chainbre annulaire 21. De cette chambre, par effet de la force centri- fuge due ä la rotation des tubes, Phydrocar- bure, diüment chauffe par de Fair ehaud cir- culant darin la tube 4, Sera projete sous forme de jet conique (fig. 6) au travers des trous 19 dans les chambres 26 d'oü, ä travers les manchons 20, il arrivera dass Je foyer 14 dann lequel il sera allume, donnant lieu ä une flaiiiine reguliere nurRTI ID="0002.0270" WI="8"HE="4" LX="1696" LY="974"> toute 1'etendrie du foyer. The apparatus operates in the following manner: The hydrocarbon is discharged under pressure through distributors 15 and 16 (fig. 1) and through openings 15' in the flat wall of box 7, will actuate the throttle valve. the turbine 6. This will turn and drive parts 1, 2 and 4 in rotation. ring 21. From this chamber, by the effect of the centrifugal force due to the rotation of the tubes, the hydrocarbon, duly heated by the heat circulating through the tube 4, will be projected in the form of a conical jet (fig. 6) through the holes 19 in the chambers 26 from where, through the sleeves 20, it will reach the hearth 14 in which it will be lit, giving rise to a regular flame nurRTI ID="0002.0270" WI="8" HE="4" LX="1696" LY="974"> the entire area of the hearth.
