  • Method for the active damping of combustion oscillation and combustion apparatus
    Patent number: 6205764
    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.

  • Method and device for acoustic modulation of a flame produced by a hybrid burner
    Patent number: 6202401
    Abstract: A method and a device for acoustic modulation of a flame through the use of an acoustically modulated feeding of a fuel. The flame is produced by burning the fuel in a hybrid burner including a premixing burner and a pilot burner associated with the latter. The fuel is fed to the premixing burner in a main flow and to the pilot burner in a pilot flow. The pilot flow is modulated and the main flow is not modulated. The invention is of particular interest for suppressing combustion oscillations in a combustion chamber to which the hybrid burner is connected.
