Abstract
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.
Claims7
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.
