Abstract
In a method of minimizing thermoacoustic vibrations in gas-turbine combustion chambers, a modulated spraying of liquid or gaseous premix fuel into a premix burner is carried out. The premix fuel is fed by means of two fuel lines (13, 14), and the modulation of the quantity of fed fuel is effected in each case by one fuel valve per fuel line.
