Compact multi-piece spring-loaded crossfire tube

A gas turbine, comprising:

• a compressor;
• a plurality of combustors downstream from said compressor;
• a turbine downstream from said plurality of combustors;
• a crossfire tube assembly between adjacent combustors, the crossfire tube assembly comprising;
• a primary body, comprising;
• a first telescoping sleeve slidably engaged with a second telescoping sleeve defining axial and circumferential relative movement of the telescoping sleeves,
• an interlocking raceway configured to limit axial travel length of the telescoping sleeves and configured to lock the telescoping sleeves to each other, and
• a bias between the first telescoping sleeve and the second telescoping sleeve,
• a first floating collar removably disposed to the first telescoping sleeve at a first floating collar annulus,
• a second floating collar removably disposed to the second telescoping sleeve at a second floating collar annulus,
• a first liner collar disposed between the first floating collar and a first liner of a first combustor,
• a second liner collar disposed between the second floating collar and a second liner of a second combustor, and
• wherein the crossfire tube assembly is adapted to provide fluid communication from the first combustor to the second combustor.
