Zusammenfassung:A gas turbine combustor cap assembly (24) including a pre-mix tube (42, 44) with an upstream flange (60, 62) that aligns and seats the tube against a primary feed plate (66) attached to an upstream end of a support ring (48). The pre-mix tube may have an intermediate flange (64) at an intermediate position on the length of the tube that aligns and seats the tube against an intermediate structural frame (68) attached to the support ring at an intermediate position on the length of the support ring. The combustor cap assembly (24) may have multiple pre-mix tubes, including a central pre-mix tube (44) with upstream (62) and intermediate (64) flanges and a circular array of outer pre-mix tubes (44) with at least an upstream flange (64).
