Abstract
Arranged upstream of each swirl-stabilized premix burner () of a burner system there is respectively an adjustable distributing device () with control valves (V, . . . , V) and/or on/off valves (V″, . . . , V″), 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 NOemission 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 () is represented by a tree structure with distributing parameters, and values for the distributing parameters on the basis of which the distributing device () 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.
