Supplemental seal for the chordal hinge seal in a gas turbine |
摘要 |
In a gas turbine having a chordal hinge seal between an inner rail of each nozzle segment and an annular axially facing sealing surface of a nozzle support ring, a supplemental seal is disposed between the support ring and inner rail of the nozzle segment on a high pressure side of the chordal hinge seal. The supplemental seal includes a pair of sheet metal shims overlaid by a woven metallic cloth supported by a bracket secured to the nozzle support ring. The radially outer end of the cloth seal bears against a back side of the inner rail. The shims of the legs of the supplemental seal are slit along their distal margin and staggered in a circumferential direction relative to one another to provide flexibility and effective sealing engagement with the inner rail. |
