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.
