Abstract: Arranged upstream of each swirl-stabilized premix burner (1) of a burner system there is respectively an adjustable distributing device (5) with control valves (V1, . . . , V8) 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 NOx 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.

Abstract: The invention relates to a rotor end piece (1) for rotors (2) of thermal turbomachines with a circumferential slot (3), consisting of two end piece halves (4, 4?) having side faces (5, 5?) opposite one another in the installed state and of a wedge (6) which is pushed in between them and which, in the installed state, is anchored in the side faces (5, 5?) of the end piece halves (4, 4?) in a form-fitting manner, the rotor end piece (1) being arranged in the axial direction of the rotor (2) between two moving blades (7, 7?). It is characterized in that each of the end piece halves (4, 4?) is fastened in the axial direction of the rotor (2) to the two adjacent moving blades (7, 7?) by means of one interlocking connection (8, 8?, 9, 9?) each. These four interlocking connections (8, 8?, 9, 9?), instead of the rotor (2), now absorb the axial forces which are caused by the centrifugal force and the caulked wedge (6). In this way, disturbing rotor vibrations are advantageously avoided.
