Abstract

Beschrieben wird ein Plenum, insbesondere das Luft-Plenum einer Gasturbinenbrennkammer, mit wenigstens zwei Strömungseinlässen, zum Einbringen von Gasströmen in das Plenum, in der die Gasströme im wesentlichen entlang der Innenwandung des plenums geführt und derart aufeinandergerichtet sind, dass die Gasströme nach Zusammentreffen als freier Gasstrom von der Innenwandung weggerichtet sind.A plenum is described, in particular the air plenum of a gas turbine combustion chamber, with at least two flow inlets, for the introduction of Gas flows into the plenum, in which the gas flows essentially along the inner wall of the plenum and are directed towards each other in such a way that the Gas flows after meeting as a free gas flow from the inner wall are directed away.

Die Erfindung zeichnet sich dadurch aus, dass an der Innenwandung (3) wenigstens ein, in Wirkverbindung zur Strömungsrichtung der an der Innenwandung (3) geführten Gasströme (1, 2) orientiertes Strömungshindernis (7) vorgesehen ist.

Figure 00000001
The invention is characterized in that at least one flow obstacle (7) is provided on the inner wall (3) that is operatively connected to the direction of flow of the gas streams (1, 2) guided on the inner wall (3).
