Abstract:
A method for determining when a combustor is experiencing hardware damage includes sensing acoustic vibrations of a plurality of combustor cans, determining a center frequency for each acoustic tone of the sensed acoustic vibrations within a predetermined frequency range, and indicating an alarm when a center frequency of one or more of the combustor cans changes in a different manner compared to a representative center frequency of the plurality of combustor cans.
