Abstract
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. In one form, the side face portions of the bristles of the bristle pack form the seal by engaging against a planar sealing surface.
