A resonator module for a combustion turbine power plant, where the combustion turbine power plant defines a flow path. The resonator module includes a first member, an a second member. The first member has a size substantially smaller than the diameter of said flow path and a plurality of openings therethrough. The openings are in fluid communication with the flow path. The second member has a size generally equal to said first member. The second member is in a generally spaced relation to the first member and encloses a volume of gas between the first and second members.

1. A resonator module in combination with a combustion turbine power plant, wherein said combustion turbine power plant has a compressor assembly, a combustor assembly, a turbine assembly, and a transition section between said combustor assembly and said turbine assembly which define a flow path, said resonator module comprising: a first member having a size substantially smaller than the diameter of said flow path and a plurality of openings therethrough; a second member maintained in a generally spaced relation to said first member and defining a volume of gas between said first member and said second member; said first member having said openings in fluid communication with said flow path; said transition section having a housing comprising said first member; said housing having an inner surface and an outer surface, and being adjacent to and defining a portion of said flow path for said working gas; said second member having attached a closed sidewall extending from the periphery of said second member generally perpendicular to said second member; and said sidewall being attached to the perimeter of said first member on said outer surface. 2. The resonator module of claim 1, wherein said sidewall is welded to said housing outer surface. 3. The resonator module of claim 2, wherein said first member is generally rectangular. 4. The resonator module of claim 3, wherein said first member has sides about 2.0 inches (5.08 cm) and 3.0 inches (7.62 cm). 5. The resonator module of claim 4, wherein said openings are circular and between about 0.060 inches (0.15 cm) and 0.12 inches (0.30 cm) in diameter. 6. The resonator module of claim 5, wherein said openings are about 0.090 inches (0.22 cm) in diameter. 7. The resonator module of claim 6, wherein: said second member includes a plurality of openings; and said second member is structured to be coupled to a purging air supply which has a greater pressure that said working gas.
