Abstract
Description
Die Erfindung bezieht sich auf eine Gasturbinenbrennkammer mit Brennkammerschindeln, wobei die Brennkammerschindeln an einer Tragstruktur der Gasturbinenbrennkammer befestigt sind und jeweils zumindest ein Mischluftloch aufweisen, welches fluchtend zu einem Mischluftloch der Tragstruktur angeordnet ist.The invention relates to a gas turbine combustor with combustion chamber shingles, with the combustion chamber shingles on a support structure of the gas turbine combustion chamber are attached and each have at least one mixed air hole, which arranged in alignment with a mixed air hole in the supporting structure is.
Aus dem Stand der Technik ist es bekannt, Schindeln in Gasturbinenbrennkammern einzusetzen, um die Trag- und Dichtstruktur vor der intensiven Wärmeeinstrahlung der Flamme zu schützen. Die Tragstruktur bleibt dadurch relativ kühl und behält ihre mechanische Festigkeit. Demgemäß ist es erforderlich, Mischluft durch ein Mischluftloch in der Tragstruktur sowie durch ein Mischluftloch der Brennkammerschindel von außen von einem Ringkanal nach innen in die Brennkammer zu führen.It is known from the prior art to shingles in gas turbine combustion chambers used to support and seal structure before the intense heat of the flame protect. The support structure remains relatively cool and maintains its mechanical strength. Accordingly, it is necessary Mixed air through a mixed air hole in the supporting structure and through a mixed air hole in the combustion chamber shingle from the outside from an annular channel into the combustion chamber respectively.
Derartige Konstruktionen sind beispielsweise aus der US 6,145,319 oder EP 972 992 A2 bekannt.Such constructions are for example from the US 6,145,319 or EP 972 992 A2.
Die aus dem Stand der Technik bekannten Konstruktionen sind so ausgebildet, dass der Durchmesser des Mischluftloches der Tragstruktur (Schindelträger) höchstens geringfügig größer ist, als der Durchmesser des Mischluftlochs der Brennkammerschindel. Der Größenunterschied dient beim Stand der Technik nur dazu, sicherzustellen, dass bei der ungünstigsten Kombination aller Fertigungs- und Montagetoleranzen der Rand des Mischluftlochs der Brennkammerschindel nicht vom Rand des Mischluftlochs der Tragstruktur überragt wird.The constructions known from the prior art are formed so that the diameter of the mixed air hole Support structure (shingle support) at most slightly larger is than the diameter of the mixed air hole of the combustion chamber shingle. The difference in size is used in the prior art just to make sure that the worst possible combination of all manufacturing and assembly tolerances the edge of the Mixing air hole of the combustion chamber shingle not from the edge of the Mixed air hole of the support structure is towered over.
Falls nun während des Betriebes ein Spalt zwischen dem Schindelrand und der Tragstruktur auftritt, entweicht durch diesen wegen der großen Druckdifferenz zwischen dem Schindelinnenraum und dem Mischluftloch relativ viel Kühlluft.If there is a gap between the Shingle edge and the supporting structure occurs, escapes through this because of the large pressure difference between the interior of the shingle and the mixed air hole relatively much cooling air.
Um zu verhindern, dass durch die dabei auftretende Überhitzung die Brennkammerschindel vorzeitig versagt, muss deutlich mehr Kühlluft durch die Brennkammerschindel geleitet werden. Diese zusätzliche Kühlluft steht somit nicht mehr für eine Verbesserung der Brennstoffaufbereitung und der damit verbundenen Stickoxidemissionsverminderung zur Verfügung.To prevent it from overheating the combustion chamber shingle fails prematurely must be clear more cooling air passed through the combustion chamber shingle become. This additional cooling air is therefore no longer available for an improvement in fuel processing and with it associated nitrogen oxide emission reduction available.
Der Erfindung liegt die Aufgabe zu Grunde, eine Gasturbinenbrennkammer mit Brennkammerschindeln der eingangs genannten Art zu schaffen, welche bei einfachem Aufbau, einfacher, kostengünstiger Herstellbarkeit und einfacher Montage eine hohe Lebensdauer aufweist und Überhitzungen der gesamten Konstruktion vermeidet.The object of the invention is a gas turbine combustion chamber with combustion chamber shingles of the type mentioned To create kind, which with simple construction, simpler, less expensive Manufacturability and easy assembly a high Has lifespan and overheating of the entire construction avoids.
Erfindungsgemäß wird die Aufgabe durch die Merkmalskombination des Hauptanspruchs gelöst, die Unteransprüche zeigen weitere vorteilhafte Ausgestaltungen der Erfindung.According to the invention, the object is achieved by the combination of features of the main claim, the sub-claims show further advantageous embodiments of the invention.
Erfindungsgemäß ist vorgesehen, dass der Durchmesser des Mischluftlochs der Tragstruktur deutlich größer ist, als der Durchmesser des Mischluftlochs der Brennkammerschindel.According to the invention it is provided that the diameter of the Mixed air hole of the support structure is significantly larger than that Diameter of the mixed air hole in the combustion chamber shingle.
Die erfindungsgemäße Ausgestaltung zeichnet sich durch eine Reihe erheblicher Vorteile aus.The configuration according to the invention is characterized by a A number of significant advantages.
Durch die erfindungsgemäße Wahl der Durchmesserverhältnisse steht der Schindelrand, von der Außenseite der Tragstruktur aus gesehen, deutlich sichtbar in den freien Durchmesser des Mischluftloches vor. Hierdurch bildet sich ein Staudruck auf dem verdickten Schindelrand. Weiterhin wird der Durchflusskoeffizient des Mischluftloches erhöht. Tritt nun im Betrieb ein Spalt zwischen dem Schindelrand und dem der Tragstruktur auf, dann wirkt der oben genannte Staudruck einem Ausströmen von Kühlluft aus dem Schindelinnenraum entgegen. Bei entsprechender Wahl des Durchmessers des Mischluftloches der Tragstruktur ist der Staudruck auf dem Schindelrand gleich dem Druck im Schindelinnenraum. Somit wird ein Ausströmen von Kühlluft aus dem Schindelinnenraum gänzlich verhindert.Through the choice of diameter ratios according to the invention stands the edge of the shingle from the outside of the supporting structure seen from clearly visible in the free diameter of the Mixed air hole before. This creates a dynamic pressure the thickened edge of the shingle. Furthermore, the flow coefficient of the mixed air hole increased. Now occurs in operation a gap between the edge of the shingle and that of the supporting structure then the above-mentioned dynamic pressure acts on an outflow of cooling air from the interior of the shingle. With appropriate Choice of the diameter of the mixed air hole Supporting structure, the dynamic pressure on the edge of the shingle is the same the pressure inside the shingle. Thus there is an outflow completely prevented by cooling air from the interior of the shingle.
Erfindungsgemäß kann bei einer entsprechenden Abstimmung der Durchmesser des Mischluftlochs der Tragstruktur und des Mischluftlochs der Brennkammerschindel erreicht werden, dass durch den starken Staudruck auf dem verdickten Rand der Brennkammerschindel beim Auftreten eines Spalts zwischen der Brennkammerschindel und der Tragstruktur, welcher durch eine Überhitzung der Schindel hervorgerufen wird, zusätzliche Kühlluft aus dem Mischluftloch in den Schindelinnenraum fließt und damit die Kühlung der Brennkammerschindel intensiviert.According to the invention can with a corresponding vote Diameter of the mixed air hole of the support structure and the Mixing air hole of the combustion chamber shingle can be achieved that due to the strong back pressure on the thickened edge of the Combustion chamber shingle when there is a gap between the Combustion chamber shingle and the supporting structure, which by a Overheating of the clapboard is caused, additional Cooling air from the mixed air hole into the interior of the shingle flows and thus intensifies the cooling of the combustion chamber shingle.
Erfindungsgemäß ist somit eine adaptive Kühlung realisiert, bei welcher die Kühlluftmenge selbsttätig an die Temperaturbelastung der Brennkammerschindel angepasst wird.Adaptive cooling is thus implemented according to the invention, in which the amount of cooling air automatically depends on the temperature load the combustion chamber shingle is adjusted.
Erfindungsgemäß wird der verdickte Rand der Brennkammerschindel durch ein gesondertes Muster von Effusionslöchern gekühlt. Die Effusionslöcher können dabei auf der Rückseite der Oberfläche der Brennkammerschindel oder im Schindelrand beginnen, wobei sie auf der dem Schindelinnenraum oder der Tragstruktur zugewandten Seite eintreten können. Die Effusionslöcher enden auf der Oberfläche der Brennkammerschindel oder an der Innenseite des Mischluftlochs der Brennkammerschindel. Die Effusionslöcher können ohne oder mit einer Umfangskomponente um die Achse des Mischluftloches zur. Heißgasseite der Brennkammerschindel verlaufen.According to the thickened edge of the combustion chamber shingle through a separate pattern of effusion holes cooled. The effusion holes can be on the back the surface of the combustion chamber shingle or in the edge of the shingle begin, being on the inside of the shingle or the Support structure facing side can enter. The effusion holes end on the surface of the combustion chamber shingle or on the inside of the mixed air hole in the combustion chamber shingle. The effusion holes can be without or with a peripheral component around the axis of the mixed air hole. Hot gas side the combustion chamber shingle.
Es ergibt sich somit, dass die Kühlluftmenge im Ausgangszustand der Gasturbinenbrennkammer so gewählt werden kann, dass sie für den normalen Betrieb gerade ausreichend ist. Somit steht die maximale Luftmenge für die Schadgasreduzierung zur Verfügung. In Extremsituationen, bei denen die Brennkammerschindel thermisch stärker belastet wird, wird selbsttätig die Kühlung erhöht, sodass ein langanhaltender und sicherer Betrieb möglich ist.It follows that the amount of cooling air in the initial state the gas turbine combustion chamber can be selected that it is just sufficient for normal operation. The maximum amount of air thus stands for the reduction of harmful gas to disposal. In extreme situations where the Combustion chamber shingle is subjected to greater thermal stress automatically increases the cooling, so that a long-lasting and safe operation is possible.
