Abstract
In the case of swirl-stabilized premix burners (), an axial mass flow distribution of the fuel introduced which has especially favorable values with respect to characteristics such as NOemission 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 () 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 () 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, 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.
