Description
Die vorliegende Erfindung bezieht sich auf das Gebiet der Brennertechnik, wie sie insbesondere bei Gasturbinen Anwendung findet. Sie betrifft eine Brennstofflanze zum Eindüsen von flüssigen und/oder gasförmigen Brennstoffen in eine Brennkammer, welche Brennstofflanze Teil eines von einem Verbrennungsluftstrahl in einer Hauptströmungsrichtung umströmten sekundären oder tertiären Brenners ist, und innerhalb eines äusseren Lanzenmantels einen Flüssigbrennstoffkanal zur Zuführung von Flüssigbrennstoff, einen den Flüssigbrennstoffkanal umgebenden Gaskanal zur Zuführung von gasförmigen Brennstoff und einen den Gaskanal umgebenden Luftkanal zur Zuführung von Kühl- bzw. Zerstäuberluft umfasst, sowie erste Mittel zum radialen Eindüsen des Flüssigbrennstoffes aus dem Flüssigbrennstoffkanal in die Brennkammer sowie zweite Mittel zum radialen Eindüsen des gasförmigen Brennstoffes aus dem Gaskanal in die Brennkammer.The present invention relates to the field of burner technology as it is is used in particular in gas turbines. It affects a fuel lance for injecting liquid and / or gaseous fuels into a combustion chamber, which fuel lance is part of a combustion air jet in a secondary or tertiary burner with a flow around it, and a liquid fuel channel within an outer lance jacket Supply of liquid fuel, a surrounding the liquid fuel channel Gas channel for the supply of gaseous fuel and one the gas channel surrounding air duct for supplying cooling or atomizing air, and first means for radially injecting the liquid fuel from the liquid fuel channel into the combustion chamber and second means for radial injection of the gaseous fuel from the gas channel into the combustion chamber.
Eine solche Brennstofflanze ist z.B. aus einer früheren Patentanmeldung DE-A1-43 26 802 der Anmelderin bekannt.Such a fuel lance is e.g. from an earlier patent application DE-A1-43 26 802 known to the applicant.
Aus der eingangs genannten Druckschrift DE-A1-43 26 802 ist eine Brennstofflanze bekannt, die von der Anmelderin derzeit bei ihren Gasturbinen (siehe dazu auch die Druckschriften US-A-5,341,018, US-A-5,626,017 und EP-A1-0 620 362) verwendet wird. Die Düsen für gasförmigen Brennstoff und Flüssigbrennstoff (Oel etc.) sind dabei kombiniert.A fuel lance is known from the document DE-A1-43 26 802 mentioned at the beginning known by the applicant currently in their gas turbines (see also the publications US-A-5,341,018, US-A-5,626,017 and EP-A1-0 620 362) is used. The nozzles for gaseous fuel and liquid fuel (Oil etc.) are combined.
In der erwähnten Druckschrift erfolgt die Eindüsung des flüssigen Brennstoffes nach dem sogenannten Air-Blast-Prinzip, d.h. der als Film auf einer Zerstäuberlippe aufgebrachte Brennstoff wird im Scherfeld der umgebenden Luftströmung zerstäubt und als Brennstoffnebel der Verbrennungsluft beigemischt. Erfolgt die Eindüsung quer zur Strömungsrichtung der Verbrennungsluft, so wird die Eindringtiefe ausschliesslich vom Luftimpuls bestimmt. Der Eigenimpuls des flüssigen Brennstoffes wird lediglich zur Filmerzeugung, nicht aber zur Unterstützung des Brennstoffstrahles benutzt.In the mentioned publication, the liquid fuel is injected according to the so-called air blast principle, i.e. that as a film on an atomizer lip Applied fuel is in the shear field of the surrounding air flow atomized and mixed with the combustion air as a fuel mist. Does that happen Injection transverse to the direction of flow of the combustion air, so is the depth of penetration determined exclusively by the air pulse. The momentum of the liquid Fuel is used only for film production, but not to support the Fuel jet used.
Zur Erzeugung eines möglichst homogenen Brennstoff/Luft-Gemisches ist es erforderlich, dass der Brennstoff aus dem Nachlauf der Düse im Querschnitt der Verbrennungsluft verteilt wird. Bei hohen Querströmungen ist ein entsprechend hoher Strahlimpuls notwendig. Dieser hohe Strahlimpuls kann mit der Zerstäuberluft alleine nicht erreicht werden. Deshalb soll der Eigenimpuls des eingedüsten flüssigen Brennstoffes (bzw. des gasförmigen Brennstoffes) unterstützend ausgenützt werden. Der Zerfall des Brennstoffstrahles erfolgt durch Strahlinstabilitäten nach einigen Strahldurchmessern Lauflänge. To generate a fuel / air mixture that is as homogeneous as possible, it is necessary that the fuel from the wake of the nozzle in cross section of the Combustion air is distributed. In the case of high cross currents, one is appropriate high beam pulse necessary. This high jet impulse can with the atomizing air cannot be achieved alone. Therefore, the intrinsic impulse should be injected liquid fuel (or gaseous fuel) is used as a support become. The fuel jet decays due to jet instabilities after a few beam diameters.
Es ist daher Aufgabe der Erfindung, eine Brennstofflanze für die Eindüsung von Flüssigbrennstoff und/oder gasförmigem Brennstoff in einem sekundären oder tertiären Brenner zu schaffen, welche die geschilderten Nachteile bisheriger Lanzen vermeidet und insbesondere eine Verkürzung der Aufenthaltszeit des Flüssigbrennstoffes in der Vormischstrecke und damit eine Reduzierung des zugemischten Wasseranteils ermöglicht.It is therefore an object of the invention to provide a fuel lance for the injection of Liquid fuel and / or gaseous fuel in a secondary or to create tertiary burners, which have the disadvantages described previous lances avoids and in particular a shortening of the residence time of the liquid fuel in the premixing section and thus a reduction in the admixed Allows water share.
Die Aufgabe wird durch die Gesamtheit der Merkmale des Anspruchs 1 gelöst. Der Kern der Erfindung besteht darin, den Flüssigbrennstoff mittels einer geeigneten Leitrohranordnung als Plain-Jet radial zur Hauptströmungsrichtung einzudüsen. Diese Art der Eindüsung hat zur Folge, dass die Aufenthaltszeit des Flüssigbrennstoffes in der Vormischstrecke vermindert wird und somit weniger Wasser zur Verhinderung eines Flammenrückschlages zugegeben werden muss. Ein weiterer Vorteil ist die durch diese Anordnung verbesserte Brennstoff-Luft-Mischung. Insbesondere kann so das bereits für die Gaseindüsung optimierte, vorhandene Luftströmungsfeld der Hauptströmung auch für die Zerstäubung und Mischung des Flüssigbrennstoffs ausgenutzt werden.The object is achieved by the entirety of the features of claim 1. The essence of the invention is the liquid fuel by means of a suitable Guide tube arrangement as a plain jet radially to the main flow direction. This type of injection means that the liquid fuel stays in the vehicle for a while is reduced in the premixing section and thus less water must be added to prevent a flashback. On Another advantage is the improved fuel-air mixture due to this arrangement. In particular, the existing one that has already been optimized for gas injection can be used Air flow field of the main flow also for atomization and mixing of the liquid fuel can be used.
Besonders günstige Strömungsverhältnisse ergeben sich, wenn gemäss einer ersten bevorzugten Ausführungsform der erfindungsgemässen Brennstofflanze die beiden Leitrohre bündig mit der Innenkontur des Lanzenmantels enden.Particularly favorable flow conditions result if according to a first preferred embodiment of the fuel lance according to the invention Both guide tubes end flush with the inner contour of the lance jacket.
Die Eindüsung des gasförmigen Brennstoffs und des umgebenden Luftmantels gestaltet sich besonders günstig, wenn sich gemäss eine zweiten bevorzugten Ausführungsform das zweite Leitrohr im Bereich des Luftkanals im Aussendurchmesser zur Mündung hin konisch verjüngt, und sich das erste Leitrohr im Bereich des Gaskanals im Aussendurchmesser zur Mündung hin konisch verjüngt. The injection of the gaseous fuel and the surrounding air jacket turns out to be particularly favorable if according to a second preferred Embodiment the second guide tube in the region of the air duct in the outer diameter tapered towards the mouth, and the first guide tube in the area of the gas channel tapers conically in the outside diameter towards the mouth.
Die Erfindung soll nachfolgend anhand eines Ausführungsbeispiels im Zusammenhang mit der Zeichnung näher erläutert werden. Die einzige Figur zeigt im Längsschnitt den Kopfbereich einer Brennstofflanze gemäss einem bevorzugten Ausführungsbeispiel der Erfindung mit radialer Eindüsung des gasförmigen Brennstoffes und des Flüssigbrennstoffs durch zwei konzentrisch ineinander angeordnete Leitrohre.In the following, the invention will be described in connection with an exemplary embodiment be explained in more detail with the drawing. The only figure shows in Longitudinal section of the head region of a fuel lance according to a preferred one Embodiment of the invention with radial injection of the gaseous Fuel and the liquid fuel by two concentrically arranged one inside the other Guide tubes.
In der einzigen Figur ist im Längsschnitt ein bevorzugtes Ausführungsbeispiel einer
Brennstofflanze nach der Erfindung wiedergegeben. Die Brennstofflanze 10,
die sich entlang einer Lanzenachse 24 erstreckt, die ihrerseits im wesentlichen
parallel zur Hauptströmungsrichtung 25 einer die Lanze umströmenden Verbrennungsluftströmung
liegt, ist in der Figur nur mit ihrem Kopfbereich dargestellt. In
der Brennstofflanze 10 sind konzentrisch zur Lanzenachse 24 ineinanderliegend
ein Flüssigbrennstoffrohr 16, ein Gasrohr 14 und ein Lanzenmantel 12 angeordnet.
Das Innere des Flüssigbrennstoffrohres 16 bildet einen Flüssigbrennstoffkanal
17, durch welchen Flüssigbrennstoff, insbesondere Oel oder dgl., zur Eindüsung in
Richtung des eingezeichneten Pfeiles in den Lanzenkopf 11 geführt wird. Zwischen
dem Flüssigbrennstoffrohr 16 und dem Gasrohr 14 ist ein Gaskanal 15
gebildet, durch welchen gasförmiger Brennstoff in Richtung des eingezeichneten
Pfeiles zum Eindüsen in den Lanzenkopf 11 geführt wird. Zwischen dem Gasrohr
14 und dem Lanzenmantel 12 schliesslich ist ein Luftkanal 13 gebildet, durch welchen
in Richtung des eingezeichneten Pfeiles Luft in den Lanzenkopf 11 geführt
wird. Anstelle der in der Figur gezeigten konzentrischen Anordnung der Rohre 12,
14 und 16 ist es in bestimmten Fällen denkbar und auch vorteilhaft, die Rohre so
anzuordnen, dass der Gaskanal 15 bzw. der Flüssigbrennstoffkanal 17 exzentrisch
angeordnet sind. In the single figure, a preferred embodiment is one in longitudinal section
Fuel lance reproduced according to the invention. The
Erfindungsgemäss wird der Flüssigbrennstoff aus dem Flüssigbrennstoffkanal 17
radial in Form eines Plain-Jets in die Brennkammer eingedüst, in welche die
Brennstofflanze 10 hineinragt. Zur Eindüsung ist ein erstes Leitrohr 23 vorgesehen,
welches in radialer Richtung vom Flüssigbrennstoffkanal 17 abgeht und im
Bereich einer (kreisförmigen) Mantelöffnung 22 im Lanzenmantel 12 endet. Der
gasförmige Brennstoff wird ebenfalls aus dem Gaskanal 15 radial zur Lanzenachse
24 und damit zur Hauptströmungsrichtung 25 in die Brennkammer eingedüst.
Dazu ist ein zweites Leitrohr 21 vorgesehen, welches in radialer Richtung
vom Gaskanal 15 ausgeht und ebenfalls im Bereich der Mantelöffnung 22 endet.
Beide Leitrohre 21, 23 sind mit Abstand konzentrisch ineinander angeordnet, so
dass der gasförmige Brennstoff im derart gebildeten Ringspalt zwischen den beiden
Leitrohren 21, 23 geführt wird. Der Durchmesser der Mantelöffnung 22 ist relativ
zum Aussendurchmesser des zweiten Leitrohres 21 so gewählt, dass ein
ringförmiger Spalt zur Erzeugung eines den Gasstrahl umgebenden, schützenden
Luftmantels frei bleibt. Besonders günstig sind die Strömungsverhältnisse für den
Luftmantelstrom, wenn die beiden Leitrohre 21, 23 - wie in der Figur gezeigt -
bündig mit der Innenkontur des Lanzenmantels 12 enden.According to the invention, the liquid fuel from the
Die Umlenkung der Strömungen aus dem Gaskanal 15 und dem Luftkanal 13 aus
der axialen Richtung in die radiale Richtung und die Bildung der gewünschten
Mantelströmungen kann weiter erleichtert werden, wenn sich das zweite Leitrohr
21 im Bereich des Luftkanals 14 im Aussendurchmesser zur Mündung hin konisch
verjüngt, und sich das erste Leitrohr 23 im Bereich des Gaskanals 15 im Aussendurchmesser
zur Mündung hin konisch verjüngt.The deflection of the flows out of the
Weiterhin kann, falls notwendig, in an sich bekannter Weise Luft aus dem Luftkanal
13 zur Kühlung des Kopfteils 18 und zur Erzeugung eines axialen Luftschleiers
in den Lanzenkopf geführt werden. Dazu werden auf einem konzentrischen Ring
um die Lanzenachse 24 herum axiale Bohrungen 20 angeordnet, durch die Luft in
axialer Richtung austreten kann. Die dazu erforderliche Luft wird aus dem Luftkanal
13 über einen Kopfkanal 19 herangeführt, der im Randbereich durch den Lanzenkopf
11 verläuft. Damit wird erreicht, dass auch der Lanzenkopf 11 durch die
hindurchströmende Luft gekühlt wird.Furthermore, if necessary, air from the air duct can be made in a manner known per se
