Title: Burner with acoustically damped fuel supply system

Abstract: In a burner (14) with at least one fuel supply system (15, 16) through which the burner (14) is fed a fuel flow (12), and the fuel fed is injected via fuel nozzles and subsequently burned in a combustion chamber (11), the formation and amplification of pressure fluctuations in the combustion chamber is prevented in a simple way in terms of design by virtue of the fact that means (17) are provided which prevent periodic pressure fluctuations which occur in the combustion chamber from leading to fluctuations in the fuel flow (12) in the fuel supply system (15, 16).
