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.
