Abstract

Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung (1) zur Beeinflussung thermoakustischer Schwingungen in einem Verbrennungssystem (5), umfassend wenigstens einen Brenner (6) und wenigstens eine Brennkammer (7), wobei

  • eine sich im Bereich des Brenners (6) ausbildende Gasströmung akustisch angeregt wird und/oder
  • eine Eindüsung von Brennstoff moduliert erfolgt.
The present invention relates to a method and a device (1) for influencing thermoacoustic oscillations in a combustion system (5), comprising at least one burner (6) and at least one combustion chamber (7)
  • a gas flow forming in the region of the burner (6) is acoustically excited and / or
  • an injection of fuel is modulated.

Um die Beeinflussung der thermoakustischen Schwingungen zu verbessern, sind die akustischen Anregungen der Gasströmung und/oder die modulierten Eindüsungen des Brennstoffs zur Beeinflussung von wenigstens zwei unterschiedlichen Störfrequenzen der thermoakustischen Schwingungen abgestimmt.

Figure 00000001
In order to improve the influence of the thermoacoustic oscillations, the acoustic suggestions of the gas flow and / or the modulated injections of the fuel are tuned to influence at least two different interference frequencies of the thermoacoustic oscillations.
