Abstract

Ein System und ein Verfahren zum Reduzieren von Verbrennungsdynamik beinhalten um eine Achse herum angeordnete erste und zweite Brenner, wobei jeder Brenner mehrere Rohre, die sich wenigstens über einen Teil des Brenners axial erstrecken, und eine Brennkammer stromabwärts von den mehreren Rohren enthält. Eine Brennstoffeinspritzeinrichtung erstreckt sich durch jedes Rohr, um eine Fluidverbindung in jedes Rohr bei einem vierten axialen Abstand von der Brennkammer bereitzustellen. Der vierte axiale Abstand in dem ersten Brenner ist anders als der vierte axiale Abstand in dem zweiten Brenner.
