Abstract
A device for damping thermoacoustic pressure vibrations in a combustion chamber (1), in particular in the combustion chamber of a gas turbine, includes a pressure sensor (6) which is connected to the input of a regulating device (10), the regulating device (10) is connected at its output to a device for electrically controlling the flame in the combustion chamber (1). This device for electrically controlling the flame includes a voltage source (11) and an electrode (14). The electrode (14) is connected to a heat shield (12) which surrounds the outflow side of a burner (3) in an annular manner.
