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.

First claim

What is claimed is:

1. A combustor, comprising:
a combustor casing;
an end cover coupled to the combustor casing;
a cap assembly disposed within the combustor casing axially spaced from the end cover, the cap assembly comprising an annularly shaped outer wall, a downstream wall extending radially and circumferentially across a downstream end of the cap assembly, an upstream wall circumferentially surrounded by and attached to an inner surface of the outer wall upstream from th…
