Abstract
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.
Claims5
A method for the active damping of combustion oscillation, which comprises:
- supplying each of at least two burners of a combustion chamber with at least one medium for combustion;
- damping combustion oscillation by control of at least two actuating members each influencing a regulating variable being a quantity of the at least one medium supplied to one of the burners;
- selecting a quantity of measuring points wherein the quantity of the measuring points is smaller than the quantity of the actuating members and includes at least one measuring point;
- measuring a variable characterizing the combustion oscillation at the at least one measuring point;
- and
- controlling the actuating members using the measured variable at the at least one measuring point.
