초록 ▼

The gas turbine includes a combustor 10 having a transition piece 18 with its exit end spaced from a first-stage nozzle 22. A brush seal 26 seals about the space between the transition piece and first-stage nozzle. The brush seal includes a sealing cap 28 supported by one of the transition piece and the first-stage nozzle and having a portion 38 overlying the other of the transition piece and first-stage nozzle. A seal ring 30 is secured to the other of the transition piece and the first-stage nozzle and carries bristles 32 projecting therefrom for engagement with the overlying portion 38 of the sealing cap 28 to seal the gap between the transition piece and the first-stage nozzle.

대표청구항 ▼

A gas turbine comprising: a first-stage nozzle; a combustor having a transition piece for flowing hot gases of combustion from said combustor to said first-stage nozzle, said transition piece being spaced from said first-stage nozzle; a brush seal between said transition piece and said first-stage nozzle sealing the space therebetween, said brush seal including a sealing cap carried by said first stage nozzle, said sealing cap having a first portion angularly related to a second portion and a third portion angularly related to said second portion and overlying said transition piece and defining a gap therewith, said brush seal further including a seal ring carrying a plurality of brush bristles projecting outwardly beyond an edge portion of said ring across said gap and having tips free for engaging said overlying third portion of said sealing cap; and means carried by said transition piece for mounting said seal ring thereon such that said bristles extend across said gap to seal said space between said transition piece and said first-stage nozzle, said transition piece having a pair of walls projecting outwardly therefrom and in spaced opposition to said third portion of said sealing cap overlying said transition piece, said seal ring being disposed between said walls with the bristles carried thereby projecting outwardly of said walls with the tips engaging said overlying cap portion.
