Abstract
A system for vibration damping a fuel nozzle within a combustor includes a support plate, a fuel nozzle passage that extends through the support plate and a cylindrical damping insert that is coaxially aligned within the fuel nozzle passage and at least partially defines the fuel nozzle passage. The damping insert may include a metallic-mesh liner.
Claims20
A system for vibration damping a fuel nozzle within a combustor, comprising:
- a. a support plate;
- b. a fuel nozzle passage that extends through the support plate;
- and
- c. a cylindrical damping insert coaxially aligned within the fuel nozzle passage, wherein the damping insert at least partially defines the fuel nozzle passage.
1 more element
A combustor for a gas turbine, comprising:
- a. an outer casing and an end cover that is coupled to the outer casing;
- b. a fuel nozzle that extends downstream from the end cover within the outer casing;
- c. a cap assembly that extends radially and axially within the outer casing, the cap assembly having a support plate and a cap plate disposed downstream from the support plate, the cap plate having an opening;
- d. a fuel nozzle passage that extends through the support plate, wherein the fuel nozzle extends at least partially through the fuel nozzle passage and the opening of the cap plate;
- and
- e. a cylindrical damping insert coaxially aligned within the fuel nozzle passage, wherein the damping insert extends circumferentially around the fuel nozzle.

A gas turbine, comprising:
- a. a compressor;
- b. a combustor downstream from the compressor, the combustor having an outer casing, an end cover coupled to the outer casing and a fuel nozzle that extends axially downstream from the end cover within the outer casing;
- c. a turbine disposed downstream from the combustor;
- and
- d. a system for vibration damping of the fuel nozzle, wherein the system is disposed within the outer casing downstream from the end cover, the vibration damping system comprising:
- i. a support plate;
- ii. a fuel nozzle passage that extends through the support plate;
- and
- iii. a cylindrical damping insert coaxially aligned within the fuel nozzle passage, the damping insert comprising a metallic-mesh liner that circumferentially surrounds a portion of the fuel nozzle, wherein the damping insert at least partially defines the fuel nozzle passage.
