Abstract
In a burner () having an interior space () surrounded by at least one shell () in which burner () fuel is injected through fuel nozzles () arranged at the burner shells () into a combustion air stream () flowing within the interior space (), the fuel/air mix which is formed flows to a flame front () in a combustion chamber () within a delay time (τ), where it is ignited, the formation of combustion-driven thermoacoustic oscillations is avoided by virtue of the fact that means (), which allow fuel to be injected into the combustion air stream () via at least two fuel injection holes () distributed over the length of the means () are arranged so as to project from the burner base () into the interior space () substantially in the direction of the combustion chamber (), so that the delay time (τ) between injection of the fuel and its combustion at the flame front () corresponds to a distribution () which avoids combustion-driven oscillations in premix operation.
