Abstract: A regulating device for regulating the course of a gas turbine plant has at least one sensor for sensing a measurement variable and for outputting a measurement signal which represents the measurement variable; at least one adjusting system for influencing air and/or fuel supply to a combustion chamber of the gas turbine plant on the basis of a correcting variable; and a regulator connected to the at least one sensor so as to receive the measurement variable and to the at least one adjusting system for outputting the correcting variable, the regulator being designed to determine the correcting variable on the basis of the measurement variable received and its deviation from a pilot variable. At least one sensor is designed to sense the variation in time of at least one burner or combustion chamber parameter as measurement variable.

Abstract: A combustor assembly is provided comprising a combustor casing; a liner coupled to the combustor casing; a burner assembly coupled to the combustor casing; and at least one resonator assembly. The resonator assembly comprises a resonator outer plate having at least one opening, a resonator side wall coupled to the resonator outer plate, and a resonator inner plate defined by a portion of the liner. The resonator inner plate is coupled to the resonator side wall and has at least one slot formed therein having an aspect ratio of at least 4:1.

Abstract: A gas turbine combustion system has a combustion system wall delimiting a flow path for hot and pressurized combustion gas and at least one resonator with a resonator volume. The resonator volume is delimited by resonator walls, where one of the resonator walls is located adjacent to or is formed by the combustion system wall. The resonator has at least one cooling fluid supply opening which is open towards a cooling fluid source. It further has a neck opening which is open towards the flow path and which is implemented in the form of a neck slot.
