摘要： A gas turbine combustor comprising a combustor inner-pipe for forming a head combustion chamber and a rear combustion chamber having a diameter larger than a diameter of head combustion chamber. A combustor outer-pipe covers the combustor inner-pipe, and a fuel nozzle is disposed at an end part of the head combustion chamber for supplying fuel to said combustor inner pipe. A first group of ports are arranged for swirling and feeding air in an axial direction of the combustor inner-pipe. The first group of ports are around the fuel nozzle. A second group of ports for swirling and feeding air in a radial direction of said combustor inner-pipe are disposed in a side wall of the head combustion chamber near the fuel nozzle. A third group of ports for swirling and feeding air in a radial direction of the combustion inner-pipe and a fourth group of ports for feeding air in a radial direction of the combustor inner-pipe are provided and ar both disposed in a side wall of the head combustion chamber near the said rear combustion chamber. A fifth group of ports are disposed in a side wall of the rear combustion chamber near the head combustion chamber and a sixth group of ports are disposed in a side wall of the rear combustion chamber on a downstream side of the fifth group of ports. Another group of ports for swirling and feeding air into the head combustion chamber are disposed in a vicinity of a central portion of an end part of the head combustion chamber along an inner periphery of the fuel nozzle, with this group of ports and the first group of ports being constructed so that air flowing from both groups of ports has the same swirling direction.
