METHOD FOR OPERATING A BURNER ASSEMBLY

摘要

A method for operating a burner assembly, in particular a burner assembly of a gas turbine, wherein an evaluation variable representing the combustion stability is determined and at least one control variable is altered, at least based on the determined evaluation variable, when the determined evaluation variable does not fall within a previously defined desired range, the desired range of the evaluation variable being constant over the entire output range of the machine, and wherein the evaluation variable is determined based on measured maximum actual amplitudes in previously defined frequency bands and measured actual outputs of the burner assembly.
