Method for the active damping of combustion oscillation and combustion apparatus

摘要

A method for the active damping of combustion oscillation in a combustion chamber uses at least two actuating members. Control of the actuating members necessitates measurement of the combustion oscillation at fewer points than there are actuating members. That is achieved, in particular, by utilizing the symmetry of natural acoustic oscillation in the combustion chamber. A combustion apparatus is also provided.
