Abstract

The blower burner for liq. fuels has a blower and motor on one side of the housing and flame tube on the far side. The rear (16) of the tube (11) projects beyond the blower housing back (28) facing the blower motor (5) and reaches into the blower housing cover (22). The tube axis (6) is parallel to the blower axis (24) and the domed cover has an inside servomotor controlled (20) sleeve (19) sliding along the tube (11), the cover thus closing off outlets (27) at the rear end of the tube. The sleeve can be pre-tensioned and split in design. The blower burner has an air/fuel ratio adjuster and a pressure regulator responding to tube inside air pressure and adjusting the rev count of the blower accordingly. The regulator has an integrated measuring tube and transducer in the flame tube.

Description

Die vorliegende Erfindung bezieht sich auf einen mit einem fluiden Brennstoff gespeisten Brenner gemäß dem Oberbegriff des Hauptanspruchs.The present invention relates to a burner fed with a fluid fuel according to the preamble of the main claim.

Solche Gebläsebrenner sind für die Brennstoffe Gas und öl bekannt. Sie weisen ein Flammrohr auf, innerhalb dessen eine Brennstoffdüse gelagert ist, die den Brennstoff zentral in das Flammrohr eingibt, wobei zwischen dem Flammrohr und der Düse ein ringförmiger Zuluftkanal angeordnet ist, der von einem Gebläse gespeist ist.Such fan burners are known for the fuels gas and oil. They have a flame tube, within which a fuel nozzle is mounted, which inputs the fuel centrally into the flame tube, an annular supply air channel being arranged between the flame tube and the nozzle and being fed by a blower.

Bei den bislang bekannten Lösungen hatte das Flammrohr eine waagerechte Lage. Da das abströmseitige Ende des Flammrohrs mit einer kegelförmigen Einziehung versehen ist, besteht die Möglichkeit, daß nach Brennschluß abtropfendes Ö1 an den Außenmantel des Flammrohres gelangt und die Kegelneigung entlangrinnt. Hierbei bewegt sich das öl in Richtung auf das einströmseitige Ende des Brennrohres, was zu Verschmutzungen an den Außenteilen des Brenners führen kann.In the solutions known so far, the flame tube had a horizontal position. Since the downstream end of the flame tube is provided with a conical indentation, there is the possibility that oil dripping after the flame cut arrives at the outer jacket of the flame tube and runs along the inclination of the cone. Here, the oil moves in the direction of the inflow end of the combustion tube, which can lead to contamination on the outer parts of the burner.

Der vorliegenden Erfindung liegt mithin die Aufgabe zugrunde, eine sogenannte Kompakteinheit aus einem Brenner und Gebläse zu schaffen,

  • . der ein Entlangrinnen von öl nach dem Brennschluß des Brenners am Außenmantel des Flammrohres verhindert werden kann.
The present invention is therefore based on the object of creating a so-called compact unit from a burner and blower,
  • . which prevents the oil from running along the burner after the burner is closed on the outer jacket of the flame tube.

Die Lösung dieser Aufgabe liegt in den kennzeichnenden Merkmalen des Hauptanspruchs.The solution to this problem lies in the characterizing features of the main claim.

Weitere Ausgestaltungen und besonders vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche beziehungsweise gehen aus der nachfolgenden Beschreibung hervor, die ein Ausführungsbeispiel der Erfindung anhand derFurther refinements and particularly advantageous developments of the invention form the subject matter of the subclaims or emerge from the following description, which illustrates an exemplary embodiment of the invention with reference to

In allen drei Figuren bedeuten gleiche Bezugszeichen jeweils die gleichen Einzelheiten.In all three figures, the same reference numerals denote the same details.

An ein Gehäuse 1 einer Wärmequelle, die einen nicht dargestellten Wärmetauscher aufweist, ist im Zuge einer Öffnung 2 eine Kompakteinheit 3, bestehend aus einem Brenner 4 und einem Gebläse 5, angeflanscht. Der in die Wärmequelle hineinragende Brenner 4 besteht in seinem Inneren aus einer konzentrisch zu seiner Symmetrieachse 6 angeordneten Brennstoffzuführung 7 in Form eines Rohres; das an eine nicht dargestellte ölpumpe angeschlossen ist. Im Zuge der Rohrleitung 7 ist bei einem ölbrenner ein Ölvorwärmer 8 angeordnet.In the course of an opening 2, a compact unit 3, consisting of a burner 4 and a blower 5, is flanged to a housing 1 of a heat source which has a heat exchanger (not shown). The burner 4 protruding into the heat source consists in its interior of a fuel feed 7 arranged concentrically to its axis of symmetry 6 in the form of a tube; that is connected to an oil pump, not shown. In the course of the pipeline 7 , an oil preheater 8 is arranged in an oil burner.

Die Rohrleitung 7 endet an ihrem der Wärmequelle zugewandten Ende mit einer Brennstoffdüse 9. Die Düse beziehungsweise der Vorwärmer und das Rohr sind über vier regelmäßig im Umfang verteilte Stegbleche 10 am Innenmantel eines Flammrohres 11 gelagert, das tief in das Gehäuse 1 der Wärmequelle hineinragt. Das Flammrohr ist konzentrisch zur Achse 6 aufgebaut und ist wie das Rohr, der Vorwärmer 8 und die Düse 9 ein Zylinderbauteil. An dem der Wärmequelle zugewandten Ende 12 des Flammrohres ist eine Stauscheibe 13 angeordnet, die eine zentrale Ausnehmung 14 aufweist. In den Raum zwischen der Ausnehmung 14 und der Düse 9 ist eine Zündelektrode"15 gerichtet. Das Flammrohr ist auf seinem der Wärmequelle abgewandten rückwärtigen Ende 16 von einem Gehäuse 17, das Teil der Baueinheit 3 ist, umgeben und in ihm schräg in einem Winkel von 3° so gelagert, daß der tiefste Punkt 30 des Flammrohres dort liegt, wo sich das Flammrohr an seinem der Wärmequelle zugewandten Ende zu einem Kegel 31 einzieht. Zwischen dem Gehäuse 17 und dem Außenmantel des Flammrohrs 16 bildet sich ein zylindrischer Ringraum 18, in dem in Verlängerung des Flammrohres 11 eine Hülse 19 in Richtung der Achse 6 auf dem Flammrohr verschiebbar gelagert ist. Das Flammrohr 11 ist an seinem rückwärtigen Ende 16 mit Ausnehmungen 27 versehen, die radial über den Mantel verteilt werden. Durch Verschieben der die Ausnehmungen 29 mehr oder weniger verdeckenden Hülse mittels eines schematisch angedeuteten Stellmotors 20 ist es möglich, einen mehr oder weniger großen Durchtrittsquerschnitt aus dem Ringraum 18 in den Innenraum 21 zwischen dem Rohr und dem Innenmantel des Flammrohrs freizugeben.The pipe 7 ends at its end facing the heat source with a fuel nozzle 9. The nozzle or the preheater and the pipe are supported by four regularly spaced web plates 10 on the inner jacket of a flame tube 11 which extends deep into the housing 1 of the heat source. The flame tube is constructed concentrically to the axis 6 and, like the tube, the preheater 8 and the nozzle 9, is a cylinder component. At the end 12 of the flame tube facing the heat source, a baffle plate 13 is arranged, which has a central recess 14. In the space between the recess 14 and the nozzle 9 is an ignition electrode "15. The flame tube is surrounded on its rear end 16 facing away from the heat source by a housing 17, which is part of the structural unit 3, and is mounted in it obliquely at an angle of 3 ° so that the lowest point 30 of the flame tube lies where the flame tube retracts at its end facing the heat source to form a cone 31. A cylindrical annular space 18 is formed between the housing 17 and the outer jacket of the flame tube 16, in which a sleeve 19 in extends the flame tube 11 Is displaceably mounted on the flame tube in the direction of the axis 6. The flame tube 11 is provided at its rear end 16 with recesses 27 which are distributed radially over the jacket by displacing the sleeve more or less covering the recesses 29 by means of a schematically indicated servomotor 20 it is possible to un more or less large cross section from the annular space 18 into the interior 21 between the tube d to release the inner jacket of the flame tube.

Der Außenmantel des Gehäuses 17 beinhaltet eine Gehäuseschnecke 23 des Gebläses 5, dessen Mittelachse 24 um 3° geneigt und im Abstand zur Achse 6 steht. Bei dem Gebläse handelt es sich um ein Radialgebläse mit einem Lüfterrad 25, dessen Achse gleichermaßen zur Achse 24 fluchtet.The outer casing of the housing 17 contains a housing screw 23 of the fan 5, the central axis 24 of which is inclined by 3 ° and is at a distance from the axis 6. The blower is a radial blower with a fan wheel 25, the axis of which is equally aligned with the axis 24.

Das Gehäuse 17 ist auf der der Wärmequelle abgewandten Seite von einem schräg im Winkel von 3° auf ihm angeordneten Gehäusedeckel 22 abgedeckt, der topfförmig vertieft gestaltet ist. Die Innenwandung des Topfes ist hierbei sowohl dem Ringraum 18 als auch dem Innenraum 21 zugewandt. In diesem Deckelinnenraum ist die Hülse 19 gelagert, am Deckel ist auch der Stellmotor 20 für die Hülse befestigt. Die Hülse nimmt demgemäß sowohl einen Teil des Ringzwischenraums 18 als auch einen Teil des zentralen Innenraums des Flammenrohrs 11 auf.The housing 17 is covered on the side facing away from the heat source by a housing cover 22 arranged on it at an angle of 3 °, which is recessed in a pot-shaped manner. The inner wall of the pot is both the ring room 18 and the interior 21 facing. The sleeve 19 is mounted in this lid interior, and the servomotor 20 for the sleeve is also attached to the lid. The sleeve accordingly receives both a part of the annular space 18 and a part of the central interior of the flame tube 11.

Statt des im Ausführungsbeispiel der Figur gewählten Radialgebläses kann auch ein Querstromgebläse verwendet werden. In diesem Falle würde die Achse 24 des Motors beziehungsweise auch die der dann zur Anwendung kommenden Walze zur Achse 6 parallel und zu ihr im Abstand stehen.Instead of the radial fan chosen in the exemplary embodiment of the figure, a cross-flow fan can also be used. In this case, the axis 24 of the motor or that of the roller then used would be parallel to the axis 6 and at a distance from it.

Die Baueinheit 3 besitzt etwa Quadergestalt und dient in ihrem Inneren als Luftführung für das Gebläse. Die Baueinheit weist zwei große einander gegenüberliegende Seiten auf, von denen die Seite 27 die Frontseite bildet, die dem Gehäuse 1 der Wärmequelle zugewandt ist, während die Rückseite 28 die Seite ist, auf der der Deckel 22 und der Motor des Gebläses 5 angeordnet sind. Deckel 22 und Gebläse 5 mit Antriebsmotor überragen die Rückseite 28, während das Vorderende des Flammrohrs, das in das Gehäuse 2 der Wärmequelle 1 ragt, die Vorderseite 27 überragt.The unit 3 is roughly cuboid in shape and serves as an air duct for the blower inside. The assembly has two large opposite sides, of which the side 27 forms the front side which faces the housing 1 of the heat source, while the rear side 28 is the side on which the cover 22 and the motor of the fan 5 are arranged. Cover 22 and blower 5 with drive motor protrude beyond the rear 28, while the front end of the flame tube, which projects into the housing 2 of the heat source 1, projects beyond the front 27.

Durch die schräge Lagerung des Flammrohrs im Gehäuse 17 liegt das einströmseitige Ende des Flammrohres auf einem höheren Niveau als das abströmseitige Ende. Hierdurch ist es dem etwa noch nach Brennschluß abtropfenden öl unmöglich, in Richtung auf das Gehäuse 17 aufwärts zu wandern und die Außenseite des Gehäuses 17 oder das Gebläse zu verschmutzen.Due to the inclined mounting of the flame tube in the housing 17, the inflow end of the flame tube is at a higher level than the downstream end. As a result, it is impossible for the oil to drip, even after a short-circuit, to move upwards in the direction of the housing 17 and to contaminate the outside of the housing 17 or the fan.

Aus der Figur zwei geht nun eine erste mögliche Form der Lagerung der Hülse 19 auf dem Außenmantel 31 des Flammrohres 11 hervor, der die Aufgabe zu Grunde liegt, eine exakte Führung der Hülse am Flammrohr zu gewährleisten und Leckluftmengen auszuschließen.FIG. 2 shows a first possible form of mounting the sleeve 19 on the outer jacket 31 of the flame tube 11, which is based on the task of ensuring an exact guidance of the sleeve on the flame tube and excluding leakage air quantities.

Während das Flammrohr ein Hohlzylinder ist, der konzentrisch zur Achse 6 aufgebaut ist, ist die Hülse 19 in zwei Hülsenhälften 32 und 33 geteilt, die zwischen sich zwei Teilfugen 34 und 35 bilden. Die beiden Teilfugen werden von Abdeckelementen 36 und 37 überdeckt, die Zylinderwölbung aufweisen, wobei der Innenmantel dieser Abdeckungen in seiner Krümmung dem Außenmantel der Hülsenhälften entspricht. Die Abdeckung 36 ist mittels einer Schweißstelle 38 mit der Hälfte 33, die Abdeckung 37 mittels einer Schweißstelle 39 mit der Hälfte 32 verbunden. An den beiden Abdeckelementen 36 und 37 ist je ein Haken 40 und 41 angebracht, in den jeweils eine Zugfeder 42 beziehungsweise 43 eingehängt ist. Das Widerlager für die Federn bildet ein zweiter Haken 44 beziehungsweise 45, der an der jeweils anderen Hälfte 32 oder 33 befestigt ist. Die in ihrer Zugkraft recht kräftig bemessenen Federn haben das Bestreben, die beiden Hälften 32 und 33 der Hülse fest an den Außenmantel 31 des Flammrohres 11 anzulegen, so daß zwischen dem Außenmantel des Flammrohres und dem Innenmantel der Hülse beziehungsweise der Hülsenhälften kein Spalt für Leckluft entstehen kann. Etwaige noch vorhandene Leckreste im Bereich der Teilfugen 34 und 35 können nach außen nicht abgeleitet werden, da die Teilfugen ihrerseits vom Innenmantel der Abdeckelemente 36 und 37 abgedeckt sind. Durch die federnde Anpressung der Hülsenhälften an den Außenmantel des Flammrohres ist auch ein Ausgleich etwaiger Unrundheiten gewährleistet.While the flame tube is a hollow cylinder, which is constructed concentrically to the axis 6, the sleeve 19 is divided into two sleeve halves 32 and 33, which form two parting joints 34 and 35 between them. The two parting joints are covered by cover elements 36 and 37 which have cylinder curvature, the curvature of the inner jacket of these covers corresponding to the outer jacket of the sleeve halves. The cover 36 is connected to the half 33 by means of a weld 38, the cover 37 is connected to the half 32 by means of a weld 39. A hook 40 and 41 is attached to each of the two cover elements 36 and 37, in each of which a tension spring 42 or 43 is suspended. The abutment for the springs forms a second hook 44 or 45, which is attached to the other half 32 or 33. The springs, which are quite powerful in their tensile force, endeavor to apply the two halves 32 and 33 of the sleeve firmly to the outer jacket 31 of the flame tube 11, so that there is no gap for leakage air between the outer jacket of the flame tube and the inner jacket of the sleeve or the sleeve halves can. Any leakage residues still present in the area of the parting joints 34 and 35 cannot be drained outwards, since the parting joints are themselves covered by the inner jacket of the cover elements 36 and 37. Due to the resilient pressure of the sleeve halves on the The outer jacket of the flame tube also ensures compensation for any out-of-roundness.

Es wäre im übrigen möglich, die Hülse auch nur mit einer Teilfuge 34 oder 35 auszugestalten und nur eine einzige Abdeckung 36 oder 37 und entsprechend eine einzige Zugfeder 42 oder 43 vorzusehen.It would also be possible to design the sleeve with only one parting joint 34 or 35 and to provide only a single cover 36 or 37 and correspondingly a single tension spring 42 or 43.

8eim Ausführungsbeispiel gemäß Figur drei bildet nicht die Hülse 19 das außenliegende Teil, vielmehr ist die Hülse an den Innenmantel 46 des Flammrohres 11 angelegt. Somit liegt der Außenmantel 31 des Flammrohres frei.In the exemplary embodiment according to FIG. Three, the sleeve 19 does not form the outer part, rather the sleeve is applied to the inner jacket 46 of the flame tube 11. The outer jacket 31 of the flame tube is thus exposed.

Genau wie im Ausführungsbeispiel der Figur zwei ist auch beim Ausführungsbeispiel der Figur drei das Flammrohr mit Ausnehmungen 27 versehen, die mehr oder weniger von der Hülse 19 abgedeckt werden. Die im Ausführungsbeispiel gemäß Figur drei innenliegenden Hülsenhälften 32 und 33 weisen Ansätze 47, 48, 49 und 50 auf, die jeweils zu beiden Seiten einer Teilfuge 34 beziehungsweise 35 liegen. Zwischen zwei sich bezüglich einer Teilfuge 34 oder 35 gegenüberliegenden Ansätzen 47, 48 beziehungsweise 49, 50 ist je eine Druckfeder 51 beziehungsweise 52 verspannt, die das Bestreben hat, im Ruhezustand die Hülsenhälften 32 und 33 an-den Innenmantel 46 des Flammrohres 11 anzupressen. Somit gelingt es auch mit dieser Lösung, den Leckspalt zwischen dem Innenmantel des Flammrohres und dem Außenmantel der Hülse nahezu zum Verschwinden zu bringen. Hierbei ergibt sich bei dieser Konstruktion der Vorteil, daß die entstehenden Teilfugen 34 und 35 von Haus aus vom Flammrohr abgedeckt sind, damit können die Abdeckelemente 36 und 37 bei dieser Ausführungsart entfallen. Auch beim Ausführungsbeispiel gemäß Figur drei ist es möglich, statt zwei Teilfugen 34 und 35 nur eine der Teilfugen 34 oder 35 vorzusehen, so daß die Hülse einteilig wird und nur eine einzige Druckfeder 51 oder 52 zum Auseinanderdrücken der Teilfuge vorgesehen sein muß.Just as in the exemplary embodiment in FIG. 2, in the exemplary embodiment in FIG. Three the flame tube is provided with recesses 27 which are more or less covered by the sleeve 19. The three inner sleeve halves 32 and 33 in the exemplary embodiment according to FIG. Have projections 47, 48, 49 and 50, which are located on both sides of a parting joint 34 and 35, respectively. Between two approaches 47, 48 and 49, 50 opposite each other with respect to a parting line 34 or 35, a compression spring 51 or 52 is clamped, which strives to press the sleeve halves 32 and 33 against the inner jacket 46 of the flame tube 11 in the idle state. With this solution, the leakage gap between the inner jacket of the flame tube and the outer jacket of the sleeve almost disappears bring. This construction has the advantage that the resulting parting lines 34 and 35 are covered by the flame tube, so that the cover elements 36 and 37 can be omitted in this embodiment. In the exemplary embodiment according to FIG. Three it is also possible to provide only one of the joints 34 or 35 instead of two joints 34 and 35, so that the sleeve becomes one piece and only a single compression spring 51 or 52 has to be provided for pushing the joint apart.

Bei einer einteiligen, innen- oder außenliegenden Hülse mit einer Teilfuge ist es möglich, auf die gesonderte Spannvorrichtung zu verzichten, indem die Hülse selbst federnd ausgebildet ist.In the case of a one-piece, inner or outer sleeve with a parting line, it is possible to dispense with the separate tensioning device in that the sleeve itself is resilient.
