Abstract

Ein System enthält eine Gasturbine (10) mit einer ersten Brennkammer (13) und einer zweiten Brennkammer (15). Die erste Brennkammer (13) enthält eine erste Brennstoffleitung mit mehreren ersten Injektoren (18). Die mehreren ersten Injektoren (18) sind in einer ersten Konfiguration in der ersten Brennkammer (13) an einem ersten Brennstoffweg entlang angeordnet, und die mehreren ersten Injektoren (18) sind zum Leiten eines Brennstoffs zu einem ersten Brennraum eingerichtet. Das System enthält ferner die zweite Brennkammer (15) mit einer zweiten Brennstoffleitung, die mehrere zweite Injektoren (18) aufweist. Die mehreren zweiten Injektoren (18) sind in einer zweiten Konfiguration in der zweiten Brennkammer (15) an einem zweiten Brennstoffweg entlang angeordnet, und die mehreren zweiten Injektoren (18) sind zum Leiten des Brennstoffs zu einem zweiten Brennraum (15) eingerichtet. Die zweite Konfiguration hat relativ zu der ersten Konfiguration wenigstens einen Unterschied. Mit dem System erfolgt die Steuerung der Verbrennungsdynamik und/oder der modalen Kopplung der Verbrennungsdynamik, um die Möglichkeit einer unerwünschten Mitschwingungsantwort (z.B. eines Resonanzverhaltens) von Bauteilen in dem Turbinensystem zu reduzieren.
