Verfahren und Vorrichtung zur Beeinflussung thermoakustischer Schwingungen in Verbrennungssystemen

摘要

A burner (2) and a combustion chamber (3) are used to carry out modulated fuel injection into a re-circulating zone (7) formed in the combustion chamber in order to improve the influence of thermoacoustic vibrations. A total fuel amount is injected so that a first amount of fuel is injected in a constant manner and a second amount in a modulated manner. An Independent claim is also included for a device for affecting thermoacoustic vibrations in a combustion system.
