ABSTRACT:
A cross-fire tube for use in connecting adjacent combustors in industrial gas turbines includes a relatively flexible main spring body portion (12,50, 68, 76) extending between two end portions, each end portion including a connector (22, 26, 54, 72, 90) adapted to engage a collar portion of one of the respective combustors. Each of the connectors includes a plurality of spring loaded fingers adapted to engage at least an inside surface of a respective collar portion. When secured in place between adjacent combustor liner covers, the cross-fire tube is in axial compression. The main spring body may comprise a saw cut spring tube (12), a coil spring (52) covered by a wire reinforced ceramic fabric (66), a corrugated wire mesh fabric (70) heat treated to impart spring characteristics thereto; or a bellows type tube (76).
