Es sind nur die für das Verständnis der Erfindung wesentlichen Elemente gezeigt; insbesondere ist nicht der an sich bekannte und unveränderte Teil der Gasturbine dargestellt.It is only essential for understanding the invention Elements shown; in particular, it is not the one known per se and unchanged part of the gas turbine shown.
Bei einer Gasturbine mit zwischen jeder Brennkammer 1.2 und
dem Turbinenlaufrad 2 angeordneten Leitschaufeln 1.1 sind
diese erfindugsgemäss in die Brennkammerwand 1.2.1 integriert
und als Teile derselben ausgebildet. Sie stellen eine im
wesentlichen monolithische Brennkammer-Leitschaufeleinheit 1
dar. Die Brennkammerwand 1.2.1 geht in die Wand jeder zugehörigen
Leitschaufel 1.1 über, ohne von ihr getrennt zu sein.
Diese Brennkammer-Leitschaufeleinheit 1 ist in eine sogenannte
kalte Tragstruktur 3.1 der Gasturbinenanlage eingesetzt und
wird von dieser getragen. Aus Gründen der Montage der ganzen
Gasturbinenanlage ist diese Brennkammer-Leitschaufeleinheit 1
geteilt ausgebildet, wodurch ein radial äusseres und ein
radial inneres Segment 1.B bzw. 1.A entsteht, wobei in jedem
Segment die Leitschaufelhälften durch korrespondierende Begrenzungswände
1.1.i voneinander getrennt sind, also jede
Leitschaufel 1.1 einen nach aussen abgeschlossenen radial
inneren und radial äusseren Teil, je in einem entsprechenden
Segment 1.A bzw. 1.B, aufweist. Jedes dieser Segmente sitzt in
einer zugeordneten kalten Tragstruktur 3.1 der Gasturbinenanlage.
Zwischen jeder dieser kalten Tragstrukturen 3.1 und
dem ihr zugeordneten Segment 1.A bzw. 1.B sind Kühlluftkanäle
4 vorgesehen, welche teilweise im Innern der Leitschaufeln 1.1
verlaufen. Dabei sind die Einströmöffnungen 4.1 der
Kuehlluftkanäle 4 in der kalten Tragstruktur 3.1 im Bereich
der Leitschaufeln 1.1 angeordnet, wodurch eine Gegenstromkühlung
der Brennkammerwand 1.2.1 verwirklicht wird. Um den
thermischen Gegebenheiten gerecht zu werden sind in den Kühlluftkanälen
4 der Leitschaufeln 1.1 Leiteinrichtungen 4.2,
z.B. Prallbleche oder Leitbleche, für die Kühlluft vorgesehen.
Die die Leitschaufel 1.1 in radialer Richtung teilenden
und einander benachbarten Begrenzungswände 1.1.i einer jeden
so gebildeten Leitschaufelhälfte ensprechender Segmente kann
wenigstens einen mit der benachbarten Begrenzungswand 1.1.i
korrespondierenden Absatz 1.1.k als Dichtelement zur Verringerung
von Leckageverlusten aufweisen. Ausserdem weist jede der
Leitschaufeln 1.1 an ihren Mantelseiten Kühlluftöffnungen
1.1.m auf, wobei diese vorzugsweise und je nach den thermischen
Gegebenheiten, laufradseitig [Hinterkante] oder im Bereich
der die Leitschaufel 1.1 in zwei radiale Segmente teilenden
Begrenzungswände 1.1.i angeordnet sind. Dabei sind
diese Kühlluftöffnungen 1.1.m in den Begrenzungswänden 1.1.i
von innerem Segment 1.A zu äusserem Segment 1.B zueinander
versetzt angeordnet.In a gas turbine with between each combustion chamber 1.2 and
the turbine impeller 2 are arranged guide vanes 1.1
this integrated into the combustion chamber wall 1.2.1 according to the invention
and formed as parts of the same. You put one in
essential monolithic combustion chamber guide vane unit 1
The combustion chamber wall 1.2.1 goes into the wall of each associated one
Guide vane 1.1 over, without being separated from it.
This combustion chamber guide vane unit 1 is in a so-called
cold support structure 3.1 of the gas turbine system used and
is carried by this. For the sake of assembling the whole
This combustor guide vane unit 1 is a gas turbine system
split formed, creating a radially outer and a
radially inner segment 1.B or 1.A arises, in each
Segment the guide vane halves through corresponding boundary walls
1.1.i are separated from each other, i.e. each
Guide vane 1.1 a radially closed to the outside
inner and radially outer part, each in a corresponding
Segment 1.A or 1.B has. Each of these segments sits in
an associated cold support structure 3.1 of the gas turbine system.
Between each of these cold support structures 3.1 and
their assigned segments 1.A and 1.B are
Die Höhe der Teilung in das radial innere und das radial äussere Segment 1.A bzw. 1.B kann je nach speziellen Anlagegegebenheiten, d.h. bei optimaler Fertigung [Giesstechnik] und den Kühlverhältnissen zwischen radial ganz innen oder radial ganz aussen (0% und 100% der Kanalhöhe) liegen.The height of the division into the radially inner and the radially outer Depending on the specific investment situation, segment 1.A or 1.B i.e. with optimal production [casting technology] and the cooling conditions between radially inside or radially are completely outside (0% and 100% of the channel height).
Die die Leitschaufeln 1.1 teilenden und einander benachbarten Begrenzungswände 1.1.i jeder Leitschaufelhälfte entsprechender Segmente kann zur Rotorachse beliebig geneigt angeordnet sein.The dividing the guide vanes 1.1 and adjacent to each other Boundary walls 1.1.i corresponding to each guide vane half Segments can be arranged at any inclination to the rotor axis.
Mit dieser integrierten Ausbildung der Leitschaufeln stellen sie eine Fortsetzung der Brennkammer dar mit der zusätzlichen Aufgabe, die Gasströmung zu den Laufschaufeln des Turbinenrades umzulenken. Damit kann die im allgemeinen sehr komplex strukturierte, separat aufgebaute und separat zu montierende Leitschaufelreihe entfallen. Dies bewirkt auch, dass Kühlluftverluste [Leckage] durch die montagebedingten Spalte reduziert bzw. eliminiert werden.With this integrated formation of the guide vanes they are a continuation of the combustion chamber with the additional one Task, the gas flow to the blades of the turbine wheel redirect. This can be very complex in general structured, separately constructed and to be assembled separately Guide vane row not required. This also causes loss of cooling air [Leakage] reduced by the assembly-related column or eliminated.
Ausserdem wird die Kühlluft wieder fast vollständig dem Verbrennungskreislauf zugeführt, wobei sie durch die Gegenstromführung schon sehr gut vorgewärmt ist. Durch die integrierte Bauweise können die Kühlluftverluste sehr stark reduziert werden. Ausserdem wird durch die Gegenstromführung der Külluft sichergestellt, dass die thermisch sehr hoch belasteten Leitschaufeln die frische und damit kältere Kühlluft erhalten, somit besser gekühlt werden. Ausserdem kann die Länge der Brennkammer mit integrierter Leitschaufel um etwa die axiale Erstreckung der ersten Leitschaufelreihe gekürzt werden. Ausserdem ergibt sich dadurch der Vorteil, dass die Külluft für die erste Laufschaufelreihe der ersten Turbine nicht mehr durch die Leitschaufelreihe, sondern direkt vom Verdichter kommend der Laufschaufelreihe zugeführt werden kann. Dies ergibt somit eine deutliche Verkürzung des Kühlluftweges und somit eine Verringerung der Strömungsverluste und der zu kühlenden Oberfläche; auch eine einfachere konstruktive Ausbildung der entsprechenden Anlageteile. Durch die Teilung in die beiden Segmente der Brennkammer-Leitschaufeleinheit 1 lässt sich zudem der Vorteil verwirklichen, dass die Kühllufterwärmung zwischen den radial äusseren und den radial inneren Segmenten etwa gleichmässig verteilt wird.In addition, the cooling air is almost completely again Combustion cycle supplied, passing through the counterflow is already very well preheated. Through the integrated Design can greatly reduce the cooling air loss become. In addition, the countercurrent Cooling air ensures that the thermal loads are very high The fresh and colder cooling air is guided by guide vanes preserved, thus be cooled better. In addition, the Length of the combustion chamber with integrated guide vane by approx the axial extent of the first row of guide vanes has been shortened become. In addition, there is the advantage that the Cooling air for the first row of blades of the first turbine no longer through the guide vane row, but directly from Compressors coming into the row of blades can. This results in a significant shortening of the cooling air path and thus a reduction in flow losses and the surface to be cooled; also a simpler constructive Training of the corresponding system parts. Through the Division into the two segments of the combustion chamber guide vane unit 1 can also realize the advantage that the cooling air heating between the radially outer and the radially inner segments is distributed approximately evenly.
Da die Kühlluftströme erfindungsgemäss im wesentlichen in Serie geschaltet sind, ergeben sich gegenüber der Parallelschaltung der Kühlluftströme nach dem Stand der Technik auch wesentliche Vorteile betreffend dem Wirkungsgrad der Kühlung. Ausserdem entfallen bei der integrierten Leitschaufelausbildung die Leckageverluste an Kühlluft durch die Spalten in der Umgebung der separat gefertigten und eingesetzten Leitschaufeln. According to the invention, the cooling air flows essentially in Series connected, arise compared to the parallel connection the cooling air flows according to the prior art also significant advantages in terms of cooling efficiency. In addition, there is no need for integrated guide vane training the leakage of cooling air through the gaps in the Surroundings of the separately manufactured and used guide vanes.
