Abstract
A system for supplying pressurized fluid to a combustor of a gas turbine is disclosed. The system may include an end cover and a fuel nozzle extending from the end cover. The fuel nozzle may include a downstream end. Additionally, the system may include a cap assembly configured to receive at least a portion of the fuel nozzle. The cap assembly may include an upstream wall spaced apart from the downstream end, a downstream wall disposed proximate to the downstream end and a cap chamber defined between the upstream and downstream walls. Moreover, a conduit may extend through the end cover and the upstream wall such that a discharge end of the conduit is in flow communication with the cap chamber.
Claims20
A combustor, comprising:
- an end cover;
- a fuel nozzle extending from said end cover, said fuel nozzle including a downstream end;
- a cap assembly configured to receive at least a portion of said fuel nozzle, said cap assembly including an upstream wall spaced apart from said downstream end, a downstream wall disposed proximate to said downstream end and a cap chamber defined between said upstream and downstream walls;
- and
- a conduit extending through said end cover and said upstream wall, said conduit including a discharge end terminating within said cap chamber,
- wherein said conduit is configured to direct pressurized fluid within said cap chamber.
