ABSTRACT:
A method and a device for burning fuel with air in a combustion chamber. The air is fed to the combustion chamber through at least one air inlet and the fuel is fed to the combustion chamber through a plurality of burners. Each burner has an associated delay time corresponding to a period of time after which an acoustic impulse in the combustion chamber causes a thermal impulse during combustion of the fuel fed through the burner. The feeding of the fuel through the burner is controlled in such a way that the delay times of the burners are substantially different from one another. The invention can be used on a combustion chamber of a gas turbine.
