Abstract: A sealing arrangement for sealing between a first stage nozzle and a plurality of aft frames includes a first inner seal and a second inner seal which are circumferentially oriented and circumferentially aligned. Each of the inner seals includes a wing extending radially inward at an oblique angle. A side seal is radially disposed between the first inner seal and the second inner seal. The side seal includes a first wing extending radially outward at an oblique angle and a second wing extending radially outward at an oblique angle, the first wing of the side seal sealingly interfaces with the wing of the first inner seal and the second wing of the side seal sealingly interfaces with the wing of the second inner seal.

Abstract: A crossfire tube assembly is positioned between adjacent combustors, the crossfire tube assembly having a primary body made up of a first telescoping sleeve slidably engaged with a second telescoping sleeve. An interlocking raceway is configured to limit axial travel length of the telescoping sleeves and lock the telescoping sleeves to each other. A bias is positioned between the first telescoping sleeve and the second telescoping sleeve. First and second floating collars are removably disposed to the first and second telescoping sleeves at a first and second floating collar annulus. First and second liner collars are disposed between the first and second floating collars on the first and second combustors. The crossfire tube assembly is adapted to provide fluid communication from the first combustor to the second combustor serving a gas turbine.

Abstract: A sealing arrangement for sealing between a first stage nozzle and a plurality of aft frames includes a first inner seal and a second inner seal which are circumferentially oriented and circumferentially aligned. A side seal is radially disposed between the first inner seal and the second inner seal. The side seal includes a first portion that is axially offset from the first inner seal and the second inner seal and a second portion abutting the first inner seal and the second inner seal. Also disclosed is an aft frame having a forward face and an aft face. The aft frame includes at least one side seal slot that extends along a side portion. A first portion of the side seal slot is axially offset from the aft face. A second portion of the side seal slot is axially and radially offset from the first portion.
