Abstract: Systems and methods for frequency separation in a gas turbine engine are provided herein. The systems and methods for frequency separation in a gas turbine engine may include determining a hot gas path natural frequency, determining a combustion dynamic frequency, and modifying a compressor discharge temperature to separate the combustion dynamic frequency from the hot gas path natural frequency.

Abstract: A system includes a gas turbine engine having a first combustor and a second combustor. The first combustor includes a first set of fuel nozzles and a first plurality of injection pegs. The first plurality of injection pegs are disposed in a first configuration upstream of the first set of fuel nozzles, along a first fuel path, and the first plurality of injection pegs are configured to route a fuel to the first set of fuel nozzles. The system further includes a second combustor having a second set of fuel nozzles and a second plurality of injection pegs. The second plurality of injection pegs are disposed in a second configuration upstream of the second set of fuel nozzles, along a second fuel path, and the second plurality of injection pegs are configured to route the fuel to the second set of fuel nozzles. The second configuration has at least one difference relative to the first configuration.
