    摘要: A fuel distribution system for a gas turbine with multistage burner arrangement is provided having at least one distribution line that branches off from a common fuel feed line and leads to a burner stage, and at least one element is provided in each distribution line for the specific influencing of the fuel mass flow. In such a fuel distribution system simplified controlling is made possible by a control valve being arranged in each case in one section of the distribution lines as an element for the specific influencing of the fuel mass flow, and in that a restrictor, which is preset in a fixed manner, is arranged in each case in the remaining distribution lines as an element for the specific influencing of the fuel mass flow.

    摘要: A sensor 11 detects the acoustic pressure at a first location in a combustion chamber 7 of a test rig 1 and produces an input signal which is a function of the acoustic pressure. A controller 13 receives the input signal and produces an output signal which is a function of the input signal. An acoustic actuator (16-18) receives the output signal and introduces into the combustion chamber 7 at a second location an acoustic pressure which is a function of the output signal. The acoustic actuator may comprise a fuel injector 18 or a loudspeaker. By using an appropriate control algorithm, acoustic boundary conditions corresponding to a particular gas turbine combustion chamber may be produced, at least in a certain frequency range.

    摘要: A method for operating a gas turbine set comprises the compression of an air mass flow in a compressor, feeding the compressed air mass flow into a first combustion chamber, burning the first mass fuel flow in the first combustion chamber in the compressed mass air flow, expanding the resulting hot gas in the first turbine, feeding the partially expanded hot gas into a second combustion chamber, and burning a second mass fuel flow in the second combustion chamber in the partially expanded hot gas. The method furthermore comprises supplying to the gas turbine set the first mass fuel flow and the second mass fuel flow preferably in a common supply line with a fuel supply pressure, and stipulating division of the total mass flow into a first and second mass fuel flow according to a normal operation concept. When the boundary value of the fuel supply pressure for example in the preferably common supply line is not reached, there is a deviation from the division according to the normal operating concept. Relative to the normal operation concept the first mass fuel flow is reduced by the difference mass flow and the second mass fuel flow is increased at least by the difference mass flow.
