Sealing structure for combustor liner
A sealing structure for sealing a gap between a combustor liner having an outer surface and a surrounding structure surrounding the combustor liner, includes: an annular sealing member held on the surrounding structure so as to be in contact with the outer surface of the combustor liner. The sealing member includes a plurality of sealing segments arranged in an annular configuration. The sealing structure seals the gap around the combustor liner of the combustor and absorbs, the difference in thermal expansion between the combustor liner and the surrounding structure.
1. A sealing structure for sealing a gap between a combustor liner having an outer surface and a surrounding structure surrounding said combustor liner, comprising:
a plurality of sealing segments, arranged in an annular configuration, forming an annular sealing member, each of said sealing segments separately connected to said surrounding structure so as to separately contact said outer surface of said combustor liner;
a sealing member support member fixed to said surrounding structure; and
a pressing unit configured to press said sealing member, each of said sealing segments having a sealing part and a connecting part connecting said sealing part to said sealing member support member, and said sealing part contacting said outer surface of said combustor liner by pressing said connecting part by said pressing unit.
2. The sealing structure according to claim 1 , said pressing unit is formed by connecting a pair of bifurcate, U-shaped plate springs with a connecting part.
3. The sealing structure according to claim 2 , said sealing member support member including a contact surface in contact with said sealing segments and including holes for bolts in said contact surface respectively corresponding to said bifurcate, U-shaped plate springs.
4. The sealing structure according to claim 1 , said sealing member support member supporting each of said sealing segments so as to be movable in a predetermined range.
