Abstract

See full text

A cross-fire tube for connecting adjacent combustors in a gas turbine, and a combustion section including the cross-fire tube, are disclosed. The cross-fire tube includes a hollow tubular body having opposite ends, and a plurality of purge air hole pairs is defined in the hollow tubular body and located at more than two different axial positions between the opposite ends. Purge air flows through the plurality of purge air hole pairs to create a uniform distribution of the purge air between the adjacent combustors. The velocity of the purge air exiting the ends of the cross-fire tube can be, for example, 25% higher. The cross-fire tube having the hole arrangements described herein also extends the life expectancy of the tube by reducing oxidation.
