摘要
The present application describes a method of manufacture for a late lean injection system (28) in a combustor of a combustion turbine engine. The method includes the steps of: a) identifying a desired position within the flow assembly for a late lean injector (32), wherein the late lean injector comprises a late lean nozzle (33) and a transfer tube (34); b) corresponding to the desired position for the late lean injector, identifying an injection point on the inner radial wall (24) and a late lean nozzle position on the outer radial wall (26); c) positioning the inner radial wall and the outer radial wall in an unassembled position; d) while in the unassembled position, forming a hole through the inner radial wall at the injection point and slideably engaging the transfer tube within the hole; e) installing the late lean nozzle (33) in the outer radial wall at the late lean nozzle position; f) positioning the inner radial wall and the outer radial wall in an assembled position; and g) connecting the transfer tube (34) to the late lean nozzle (32).
