Abstract
A stator blade segment includes a circumferentially extending outer blade ring, a stator blade extending radially inward from the outer blade ring, and a sealing member. The stator blade has a cavity that is formed in the interior of the blade and that communicates with the surface of the blade. The outer blade ring has a blade ring body and two blade ring protrusions. The two blade ring protrusions protrude radially outward from an anti-gas path surface of the blade ring body and face each other across a gap in an axial direction, and together with a casing, a drain recovery space is formed between the two blade ring protrusions. The blade ring body has a blade surface drain recovery passage that allows communication between the cavity and the drain recovery space. One of the two blade ring protrusions has a sealing surface.
