Gas turbine combustor with angled tube section

摘要

A combustor inner tube 102 or a burner 101 provided on the upstream side of a tail pipe 103 having a straight or substantially straight axis is disposed at an angle with respect to the axis of tail pipe 103, by which a secondary flow is produced in combustion gas. Thereby, low-temperature gas at the outer peripheral portion is mixed with high-temperature gas at the central portion so that the gas temperature distribution is made uniform.
