摘要： The invention relates to a combustion chamber (1) for a gas turbine, comprising a burner system (2) and a fuel supply system (3). The burner system (2) comprises at least two burner groups (A, B), each having at least one burner (5). The fuel-supply system (3) comprises a primary line (7) that is connected to a fuel source (8), in addition to a secondary line (9) for each burner group (A, B). Each secondary line (9) is connected to each burner (5) of the associated burner group (A, B) and to the primary line (7) via a controllable distribution valve (10). A sensor system (11) detects pressure pulsation values and/or emission values for each burner group (A, B). A controller (12) controls the distribution valves (10) in accordance with the pulsation values and/or emission values, in such a way that the pulsation values and/or emission values for each burner group (A, B) are maintained at and/or fall below predetermined threshold values.

摘要： Arranged upstream of each swirl-stabilized premix burner ( 1 ) of a burner system there is respectively an adjustable distributing device ( 5 ) with control valves (V 1 , . . . , V 8 ) and/or on/off valves (V'' 1 , . . . , V'' 16 ), by means of which various axial mass flow distributions of the fuel introduced can be set. Preferably, those which have particularly favorable values with respect to characteristics such as NO x emission and maximum amplitudes of pulsations occurring are chosen. For this purpose, Pareto solutions are determined with respect to the said characteristics, in that a distributing device ( 5 ) is represented by a tree structure with distributing parameters, and values for the distributing parameters on the basis of which the distributing device ( 5 ) is set by means of a control unit are iteratively generated in a data-processing system by an evolutionary algorithm. On the basis of the values determined by a measuring unit, solutions which are especially favorable with respect to the characteristics mentioned, especially Pareto-optimal, are selected. The distributing devices are then set during operation on the basis of the solutions of this type corresponding to respective requirements.

摘要： A sensor (11) detects the acoustic pressure at a first location in a combustion chamber (7) of a test rig I and produces an input signal which is a function of the acoustic pressure. A controller (13) which 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： The invention relates to a premixing burner comprising a swirl generator (4) and characterised in that two perforated flow elements (10, 11) disposed at a defined clearance with respect to each other are arranged in a combustion air admission area (3). The flow elements are preferably disposed in such a way that the main part of the combustion airflow passes therethrough. In the preferred embodiment, the degree of perforation of the flow elements and the clearance therebetween are defined in such a way that it is possible to prevent a reflection of possible combustion frequencies at the burner (1) output towards the combustion chamber (7).

摘要： In the case of swirl-stabilized premix burners ( 1 ), an axial mass flow distribution of the fuel introduced which has especially favorable values with respect to characteristics such as NO x emission and maximum amplitudes of pulsations occurring is used. For this purpose, Pareto solutions are determined with respect to the said characteristics, in that a distributing device ( 5 ) with control valves is represented by a tree structure with distributing parameters, and values for the distributing parameters on the basis of which the distributing device ( 5 ) is set by means of a control unit ( 10 ) are iteratively generated in a data-processing system ( 9 ) by an evolutionary algorithm. On the basis of the values determined by a measuring unit ( 11 ), solutions which are especially favorable with respect to the characteristics mentioned, espectially Pareto-optimal, are selected. The distributing devices or the premix burners of the burner system are then formed in a way corresponding to such a solution.
