Nozzle mounting and sealing assembly for a gas turbine system and method of mounting and sealing

摘要

A nozzle assembly includes a nozzle having a trailing edge of an outer band and an anti-rotation pin slot. Also included is a retaining ring extending circumferentially about the outer surface of the outer band, wherein the retaining ring includes an anti-rotation pin and an anti-rotation pin hole, wherein the anti-rotation pin is configured to fittingly reside in an axial orientation within the anti-rotation pin slot and the anti-rotation pin hole. Further included is a seal plate seated on the outer surface of the outer band and configured to retain the anti-rotation pin. Yet further included is a washer disposed within a bored portion of the seal plate, wherein the bored portion is aligned with an aperture within the retaining ring, wherein a mechanical fastener extends into the retaining ring through the bored portion to operably couple the seal plate to the retaining ring.
