Abstract: A method for detecting malfunctions in a combustion chamber of a gas turbine plant includes providing dynamic pressure signals (P1 I , P2,...., P N ), each indicative of a dynamic pressure at the outlet of a respective burner of a combustion chamber of the plant. Frequency spectra (S 1 (f), S 2 (f),..., S N (f), S 1 *(f), S 2 * (f),..., S N *(f)) of the dynamic pressure signals (P 1 , P 2 ,..., P N ) are calculated, the malfunctions of the burners are recognized according to these spectra. Each burner subject to malfunctioning is identified according to a bijective correlation between the burners and the respective dynamic pressure signals (P 1 , P 2 ,..., P N ).
