The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
1. A gas turbine cooled stationary blade comprising an outer shroud, an inner shroud and an insert of a sleeve shape, having air blow holes, inserted into an interior of the blade between said outer and inner shrouds, the blade being constructed such that cooling air entering said outer shroud flows through said insert to be blown through said air blow holes and to be further blown outside of the blade through cooling holes provided passing through a blade wall of the blade as well as to be led into said inner shroud for cooling thereof and to be then discharged outside, wherein a blade wall thickness in an area of 75% to 100% of a blade height of a blade leading edge portion of the blade is made thicker toward said insert than a blade wall thickness of other portions of the blade; the blade is provided therein with a plurality of ribs arranged up and down between 0% and 100% of said blade height on a blade inner wall on a blade convex side, said plurality of ribs extending in a blade transverse direction and protruding toward said insert; said outer and inner shrouds, respectively, are provided therein with cooling passages arranged in shroud both side end portions on blade convex and concave sides of said respective shrouds so that cooling air may flow therethrough from a shroud front portion, or a blade leading edge side portion, of said respective shrouds to a shroud rear portion, or a blade trailing edge side portion, of said respective shrouds to be then discharged outside through openings provided in the shroud rear portion; and said inner shroud is further provided therein with a plurality of cooling holes arranged along said cooling passages on the blade convex and concave sides of said inner shroud, said plurality of cooling holes communicating at one end of each hole with said cooling passages and opening at the other end in a shroud side end face so that cooling air may be blown outside through said plurality of cooling holes.
2. A gas turbine cooled stationary blade as claimed in claim 1, wherein said inner shroud is provided in an entire portion of the shroud front portion, including the shroud both side end portions thereof, with a space where a plurality of pin fins are provided erecting and said space communicates at the shroud both side end portions with said cooling passages on the blade convex and concave sides of said inner shroud.
3. A gas turbine cooled stationary blade as claimed in claim 1, wherein said cooling holes provided passing through the blade wall are provided only on the blade convex side.
4. A gas turbine cooled stationary blade as claimed in claim 1, wherein said outer and inner shrouds, respectively, are provided with a flange, side surface of which coincides with a shroud side end face on the blade convex and concave sides of said respective shrouds, so that two mutually adjacent ones in a turbine circumferential direction of said respective shrouds may be connected by a bolt and nut connection via said flange.
5. A gas turbine cooled stationary blade as claimed in claim 1, wherein a shroud thickness near a specific place where a thermal stress may arise easily, including the blade leading edge and trailing edge portions, in a blade fitting portion of said outer shroud is made thinner than a shroud thickness of other portions of said outer shroud.
6. A gas turbine cooled stationary blade as claimed in claim 1, wherein said blade leading edge portion is made in an elliptical cross sectional shape in the blade transverse direction.
7. A gas turbine cooled stationary blade as claimed in claim 1, wherein said gas turbine cooled stationary blade is a gas turbine second stage stationary blade.
