Description

Die vorliegende Erfindung betrifft eine Auskleidung für Innenwände von Brennkammern mit unter Spaltbelassung an der Innenwand anzuordnenden, im wesentlichen plattenförmigen Abschirmelementen. Weiterhin betrifft die Erfindung Strömungsbarrieren zum Einsatz in entsprechenden Auskleidungen.The present invention relates to a lining for interior walls of combustion chambers with gaps left on the inner wall to be arranged, essentially plate-shaped shielding elements. The invention further relates to flow barriers for use in appropriate linings.

Auskleidungen für Innenwände von Brennkammern, insbesondere auch solche für Gasturbinen, auf welche sich die vorliegende Erfindung auch bezieht, sind an sich bekannt. Die Brennkammern werden mit im wesentlichen plattenförmigen Abschirmelementen ausgekleidet, welche temperaturbeständig sind und wobei "plattenförmig" die Grunddimension beschreibt. Die Abschirmelemente können auch als Hohlelemente ausgebildet sein. Um unterschiedliche bzw. instationäre Wärmeausdehnungen aufnehmen zu können, werden üblicherweise zwischen benachbarten Abschirmelementen Spalte belassen. Da in diese Spalte aus der Brennkammer stammendes Heißgas eintreten kann, was zur Überhitzung an Abschirmelementen, Halteelementen oder der Brennkammerwand führen kann, ist es bekannt, zwischen Brennkammerwand und Abschirmelementen Sperrluft einzuführen, so daß die Spalte gegen Heißgaseinzug gesperrt sind.Linings for internal walls of combustion chambers, in particular also those for gas turbines on which the present one relates Invention also relates are known per se. The combustion chambers are with essentially plate-shaped shielding elements lined which are temperature resistant and where "Basic" describes the basic dimension. The shielding elements can also be designed as hollow elements. To absorb different or transient thermal expansions to be able to, are usually between neighboring Leave the shielding elements in the column. Because in this column from the Combustion chamber hot gas can enter, causing overheating on shielding elements, holding elements or the combustion chamber wall can lead, it is known, between the combustion chamber wall and shielding elements to introduce sealing air so that the Columns are blocked against hot gas intake.

Ein Teil der Sperrluft wird zur Kühlung der Abschirm- bzw. Befestigungselemente benötigt. Der Mindestluftverbrauch ist durch die zur Kühlung der Abschirm- und Befestigungselemente notwendige Luftmenge definiert. Im Idealfall sollte diese zur Kühlung benötigte Luftmenge auch zur Sperrung der Spalte ausreichen. Die Sperrung der technisch bedingt erforderlichen Spalte (Wärmedehnung stationär und instationär, Fertigungstoleranzen, Montageerfordernisse) zwischen den Abschirmelementen erfordert jedoch erheblich höhere Luftmengen. Der Luftbedarf ist somit direkt von der Spaltfläche abhängig. Part of the sealing air is used to cool the shielding or Fasteners needed. The minimum air consumption is due to the cooling of the shielding and fastening elements necessary air volume defined. Ideally, this should be The amount of air required for cooling is also sufficient to block the gaps. The blocking of the technically necessary Column (thermal expansion stationary and unsteady, manufacturing tolerances, Assembly requirements) between the shielding elements however requires significantly higher air volumes. The air requirement is therefore directly dependent on the gap area.

Weiterhin bildet sich im Inneren der Brennkammer ein Druckund Temperaturfeld aus. Bei der Bemessung des Luftbedarfs muss dieses Druck- und Temperaturfeld berücksichtigt werden. Dadurch sind lokal höhere Luftmengen erforderlich. Die vorgeschlagene Strömungsbarriere verringert die Spaltfläche und ermöglicht somit eine erhebliche Reduktion des Luftbedarfs. Zudem wird der Luftbedarf von Druck- und Temperaturfeld weitgehend entkoppelt, was ein weiteres Einsparpotential erschließt.Furthermore, a pressure and builds up inside the combustion chamber Temperature field. When measuring the air requirement this pressure and temperature field must be taken into account. This means that locally higher air volumes are required. The proposed one Flow barrier reduces the gap area and thus enables a significant reduction in air consumption. In addition, the air requirement of the pressure and temperature field is largely decouples, which opens up further savings potential.

Die Senkung des Luftbedarfs wirkt sich positiv auf die Stabilität der Brennerflammen, die Effektivität der Maschine und die Schadstoffemissionen aus und ermöglicht eine weitere Leistungssteigerung unter Einhaltung maximal gegebener Materialtemperaturen.The reduction in air consumption has a positive effect on stability the burner flames, the effectiveness of the machine and pollutant emissions and enables another Increased performance while maintaining maximum material temperatures.

Ausgehend vom vorbeschriebenen Stand der Technik liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Auskleidung für Innenwände von Brennkammern mit unter Spaltbelassung an der Innenwand anzuordnenden, im wesentlichen plattenförmigen Abschirmelementen bereitzustellen, welche durch eine effiziente Abdichtung das Einwandern von Heißgasen unter Verwendung wirtschaftlich bereitstehender Mittel vermeidet.Starting from the above-described prior art, the present invention has for its object to provide a lining for the inner walls of combustion chambers with substantially plate-shaped shielding elements to be arranged on the inner wall with gap leaving, which avoids the migration of hot gases by means of economically available means by efficient sealing.

Zur technischen Lösung wird mit der Erfindung vorgeschlagen, daß in einen Spalt zwischen benachbarten Abschirmelementen einsetzbare Strömungsbarrieren verwendet werden.As a technical solution , the invention proposes that flow barriers that can be used be used in a gap between adjacent shielding elements.

Durch den erfindungsgemäßen Einsatz von Strömungsbarrieren kann einerseits ein Einwandern von Heißgas in den Bereich zwischen Abschirmelementen und Brennkammerwandung wirksam verhindert werden, zum anderen kann die in diesem Bereich geführte Kühlluft gezielt eingesetzt werden, da sie nun nicht mehr über offene Spalte austritt. Damit reduziert sich die Sperrwirkungs-Notwendigkeit nur noch auf solche Spaltbereiche, an welchen keine Strömungsbarrieren eingesetzt sind. Through the use of flow barriers according to the invention On the one hand, hot gas can migrate into the area effective between shielding elements and the combustion chamber wall can be prevented, on the other hand, the guided in this area Cooling air can be used specifically since it is not emerges more about open column. This reduces the The blocking effect is only necessary for such gap areas, where no flow barriers are used.

Insbesondere wird nur sehr wenig Luft für Sperrluft benötigt, wodurch sich ein erheblicher wirtschaftlicher Nutzen erschließt.In particular, very little air is required for sealing air, which opens up significant economic benefits.

In erfindungsgemäßer Weise wird die Strömungsbarriere durch flexible, temperaturbeständige Dichtelemente gebildet, die in vorteilhafter Weise porös sind. Durch die Porösität ergibt sich die Möglichkeit der Kühlung der Dichtelemente.In the manner according to the invention, the flow barrier is passed through flexible, temperature-resistant sealing elements formed, which in are advantageously porous. Due to the porosity the possibility of cooling the sealing elements.

Weiterhin wird mit Vorteil vorgeschlagen, daß die Dichtelemente streifenförmig ausgebildet sind und somit zur Spaltabdichtung gut einsetzbar sind. In vorteilhafter Weise können die Dichtelemente aus Materialgemenge wie Drahtgewirke, Drahtgestricke, Drahtgemenge, Fasergemenge, Gewebe, Keramikgewebe und dergleichen gebildet werden.Furthermore, it is advantageously proposed that the sealing elements are strip-shaped and thus for gap sealing are good to use. Can advantageously the sealing elements made from a mixture of materials such as wire mesh, Wire mesh, wire mix, fiber mix, fabric, ceramic fabric and the like are formed.

Auch ist es möglich, schlauchförmige Dichtelemente auszubilden und diese nach Bedarf mit entsprechendem Material zu verfüllen.It is also possible to form tubular sealing elements and fill them with the appropriate material as needed.

In vorteilhafter Weise werden die Dichtelemente mittels Haltern in den Spaltbereich positioniert und dort fixiert.The sealing elements are advantageously made by means of holders positioned in the gap area and fixed there.

Gemäß einem weiteren vorteilhaften Vorschlag sind die Seitenkanten der Abschirmelemente mit Nuten versehen, so daß sich streifenförmige Dichtelemente in den Nuten und damit die Spalte verdeckend positionieren lassen.According to a further advantageous proposal, the side edges are of the shielding elements with grooves so that strip-shaped sealing elements in the grooves and thus the Allow the column to be hidden.

Die Erfindung bezieht sich auch auf neuartige Strömungsbarrieren für den Einsatz in Spalten zwischen Abschirmelementen von Brennkammerinnenwänden. Derartige Strömungsbarrieren ermöglichen eine effiziente und gezielte Kühlung, reduzieren den Sperrluftbedarf und wirken sich auf eine höhere Flammenstabilität sowie die Möglichkeit, die Brennkammer mit verringerter Flammentemperatur zu betreiben, aus. The invention also relates to novel flow barriers for use in gaps between shielding elements of combustion chamber inner walls. Such flow barriers enable efficient and targeted cooling the sealing air requirement and affect a higher flame stability as well as the ability to reduce the combustion chamber To operate flame temperature.
