Abstract

A stator blade ring for the last stage of a multi-stage steam turbine includes a plurality A of stator blade modules defining an annular chamber, each stator blade module including an elongated blade portion. The elongated blade portion further includes a longitudinal passageway and an inner portion brazed to a first longitudinal end of the blade portion, the inner portion including a through hole forming a portion of the annular chamber and an inner passageway extending from the through hole to the longitudinal passageway. An outer portion is brazed to a second longitudinal end of the blade portion and engaged to the steam turbine. The outer portion includes an outer passageway open to a surface of the steam turbine and the longitudinal passageway.
