摘要： A crossfire tube for connecting adjacent combustors in a gas turbine, the crossfire tube includes a hollow tubular body having opposite end portions adapted to be secured to the adjacent combustors; an annular chamber surrounding a mid-section of the hollow tubular member; a first plurality of purge air feed holes in an outer wall of the chamber, and a second plurality of purge air feed holes in an inner wall of the chamber opening into the crossfire tube. A method of supplying purge air to a crossfire tube located between a pair of adjacent combustors in a gas turbine, where the crossfire tube includes a hollow tubular body adapted for connection between the adjacent combustors, includes the steps of establishing a chamber about the tubular body; utilizing compressor discharge air as crossfire tube purge air; feeding the purge air at a first pressure approximately equal to the compressor discharge air pressure into the chamber to thereby reduce the pressure to a second, lower pressure; and subsequently feeding the purge air from the chamber into the tubular body of the crossfire tube at the lower pressure.
