Definitions
- the present invention relates to burners with liquid fuel and low emission of NO x and dust, and atomizers (or sprayers) with liquid product for such burners.
- the technical field of the invention is that of the manufacture of industrial liquid fuel burners (oil and fuel oil in particular).
- patent FR 2641365 proposes a burner comprising a primary spray part which delimits an axial mixing chamber into which the liquid fuel is introduced axially and radially or tangentially an auxiliary fluid under pressure; bedroom has primary spray nozzles each having a exit from which a jet of atomized fuel emerges; the burner has in addition to a secondary spray piece that wraps the piece of primary spraying by delimiting with it an auxiliary chamber; the secondary part carries a plurality of secondary nozzles each of which is coaxial with a primary nozzle and has a diameter greater than the orifice of exit from it; the burner has means for injecting radially in the auxiliary chamber an auxiliary fluid under pressure sufficient for it to expand in the secondary nozzles, around the jets leaving the primary nozzles, with an axial speed greater than the speed the peripheral layers of the sprayed fuel jets.
- the burner head (or end) described in this document includes, in addition to the primary and secondary nozzle holder parts, several parts removable arranged between the nozzle holder parts and the body (of the cane) of the burner: an emulsifier defining a fuel mixing chamber and auxiliary fluid, which has passages (for auxiliary fluid) equipped with fins, as well as a diaphragm (or pellet) provided with an orifice central calibrated for the introduction of fuel into the mixture, and a fuel guiding part (sometimes called an atomizer) upstream of the diaphragm; these different pieces in the general shape of discs thick are "stacked" face to face and secured to the burner head by a cap which surrounds them, which is screwed onto the burner head and which has a shoulder leaning against the periphery of the nozzle holder part spray.
- the object of the present invention is to provide burners, in particular such as those described in patent FR 97/09594 (PILLARD), that are improved.
- An objective of the invention is to simplify the production of atomizers of liquid fuel, in particular those described in the patents FR 1305391 and FR 2641365, while keeping the functions unchanged and at least equal performance.
- An objective of the invention is to allow the optimization of the Atomizer / burner “couple”, thanks to improvements concerning including the design of atomizers and removable rods atomization of liquid fuel and so the burner bodies themselves, to allow easy control of the optimization of this "Couple”.
- the invention consists, according to a first aspect, in proposing a nozzle holder part capable of being removably mounted on a rod atomization of a liquid fuel burner, which comprises a connection in rotation with said rod, which member is preferably integrated to the structure of the nozzle-holder part to increase the solidity of the connection and make it possible to avoid any relative positioning defect in particular during frequent disassembly-reassembly operations for the maintenance.
- the angle of orientation (trigonometric with respect to the axis of the burner) of the fuel jets liquid produced by the nozzle holder part can be adjusted to match precisely at the angular position of the secondary air injection nozzles.
- This allows in particular, in particular in the case of the burners illustrated Figure 2 of EP 774620 and US 5,562,437, to adjust and control the angular offset between the fuel injection port liquid and the position of the secondary nozzle, and which depends on the direction of "Rotation" printed by the burner with combustion air; the invention therefore allows to control the angular position of the room in which the liquid fuel outlet ports are drilled so that the angle orientation of the liquid fuel injection cane can be adjusted precisely, on a case-by-case basis, to optimize combustion.
- the latter has a cylindrical wall (hollow tubular) of circular section, which delimits a cylindrical cavity, which is extended and / or partially closed at one end by a transverse veil (or wall) thick (in which (which) are pierced with holes forming the nozzles of fuel spray, and which is open at its second end: the latter is provided with a notch (or cutout) extending over a part of its circumference, for example half of it; this part end thus forms the connecting member in rotation, engaging with a small clearance in a cavity or depression of complementary geometry formed at the end of the rod receiving this removable nozzle holder piece.
- Said cavity delimited by the cylindrical body of the nozzle-holder part can accommodate the other removable mounted parts on the rod of the burner which are used to form a jet of fuel, to mix it with the fluid auxiliary, as well as transporting and guiding the fluid and the fuel to the nozzles.
- the removable attachment of the nozzle holder part to the rod can be carried out, as in patent FR 2641365, using a threaded sleeve (or nut) which surrounds the nozzle holder part while resting on the periphery of its front face, which is screwed to the (threaded) end of the rod of the burner.
- said end of the nozzle holder part (or multi-nozzle) integrating the rotating connecting member further comprises a connecting member in longitudinal translation adapted to cooperate with a complementary member provided at the end of the cane; this provision facilitates assembly and disassembly by allowing hanging (and / or hang) - cantilevered at the end of the rod - the nozzle holder part and the removable parts it contains, the common longitudinal axis of the rod and the nozzle-holder part being kept substantially horizontal; this allows the sleeve to be engaged around the multi-nozzle part without the hold, however it remains perfectly aligned and pressed against the end of the cane during this operation; preferably the organ of longitudinal connection and integrated into the multi-nozzle part and is presented under the shape of a projection - such as a rib - provided on the internal face of the uncut part of said second end, which extends over a part of its circumference; the two integrated connecting members form thus a kind of hook capable of engaging in a circumferential groove corresponding provided at the end
- the invention consists in proposing a removable atomizer for fuel spray burner rod liquid, which has a longitudinal central opening (calibrated) for the fuel passage and several longitudinal peripheral orifices (for the passage of an auxiliary spraying fluid) leading to each end in an annular groove respectively provided on each face of the atomizer, each of said faces having grooves substantially radial;
- the atomizer monobloc, further comprises on a face - called rear face - a depression surrounding said central orifice and into which tangential channels open, so that when the atomizer is mounted between the end of the cane and a nozzle holder part (removable) by a sleeve-shaped fastener, the vacuum forms with the end of the rod an upstream rotation chamber fuel transported through these channels;
- the atomizer can if necessary have a second depression capable of delimiting with the nozzle holder part a mixing (emulsion) chamber;
- the atomizer features on a second face - called front face - of the radial or
- the invention consists in proposing a part removable monobloc for liquid fuel burner rod, which includes means (comprising tangential injection channels and a tapered hollow face) for guiding the fuel flow allowing the formation of a conical jet at the outlet of a central orifice, means (longitudinal channels) for passage through the part of a fluid auxiliary and means (radial or tangential channels) for guiding the fluid downstream of the central orifice and allowing the fluid to come into contact with the fuel jet.
- This one-piece piece can be accommodated easily thanks to its low thickness inside a housing (bore) provided in the nozzle holder part.

Abstract
Description
- deux ou plusieurs voies 9 tangentielles de mise en rotation du combustible liquide,
- une paroi plate ou conique 13 se terminant par un orifice 2 cylindrique ou conique de diamètre sensiblement inférieur au diamètre de sortie des voies 9 tangentielles, débouchant dans un volume 21, dénommé « chambre d'émulsion» ; ceci provoque la sortie du combustible liquide sous la forme d'un voile conique par l'effet des vitesses générées par la pression du liquide ;
- deux ou plusieurs voies 8 radiales ou tangentielles permettant l'injection vers l'axe 20 du fluide FAA, avec un angle a de convergence de préférence compris entre 30 et 90° ; ces jets de FAA ont pour effet d'entrer en contact avec le cône de combustible liquide et de former, dans le volume 21, un mélange (FAA - combustible liquide) destiné à être injecté dans le foyer de combustion par un ou plusieurs orifices ou buses 22 reliant la chambre 21 au foyer 25 (figure 9).
- on réduit les erreurs de montage par inversion d'ordre ou de sens comparé aux cannes comportant plusieurs pièces distinctes ; la pièce 1 peut être prévue avec une dissymétrie (un détrompeur) interdisant à l'opérateur de la monter à l'envers, en particulier si ses deux faces avant et arrière 6, 7 sont parallèles (α = 90°) ;
- le démontage est facilité ;
- le nombre de surfaces en contact est réduit à deux (au lieu de six surfaces pour trois pièces), ce qui réduit le nombre de risques de fuites de combustible liquide ou de FAA, et réduit quasiment à néant les risques de déformation des pièces de faible épaisseur ;
- le coût de fabrication est plus faible, puisqu'on économise quatre usinages de faces en contact et les gorges de liaison nécessaires ;
- les erreurs de choix de pièces parmi les stocks de rechange sont réduits ou annulés ;
- l'épaisseur totale de la pièce unique est nettement plus faible que le cumul des épaisseurs de trois pièces ; ce gain d'épaisseur présente de nombreux avantages induits : le fourreau cylindrique 23 appelé « écrou de blocage » est plus court, plus facile à refroidir, plus solide, et sa longueur soumise à dilatation différentielle est réduite ; la pièce 19 de sortie percée d'orifices 22 est plus rapprochée de la pièce fixe 18 solidaire de la canne, ce qui permet de lier en rotation la canne 18 et la pièce 19 de sortie.
