摘要： An annular seal flange (87) is formed at an inner peripheral edge portion of an upstream-side seal ring (83). The seal flange (87) projects in a downstream direction. When seal rings (83, 85) are viewed from radially inside, the seal flange (87) of the upstream-side seal ring (83) is designed to at least partially occlude an end gap (85f) of the downstream-side (the most downstream-side) seal ring (85).

摘要： The invention relates to a regenerative gas turbine combustor being provided to enable to reduce an amount of leakage of compressed air before preheating to compressed air after the preheating. The regenerative gas turbine combustor is such that a compressed air passage between a combustor inner cylinder 10 and a tail cylinder 12, and a combustor outer cylinder 7 is blocked by a division wall 15 at a position between a bleeding port 13 and an injection port 14, and compressed air is preheated in a regenerator 4 and then the compressed air thus preheated is burnt together with fuel. This combustor includes seal rings 17a-17c, a holder 16 installed on the inner circumferential portion of the division wall 15 and having ring grooves 25a-25c for holding the respective seal rings 17a-17c, and gaps 20 provided between the inner circumferential surfaces of the ring grooves 25a-25c and the outer circumferential surfaces of the seal rings 17a-17c.
