Disclosed is a gas turbine combustor equipped with a burner (6) constructed to fire a plurality of combustors (2) at the same time at a fuel/air ratio suitable for gas turbine ignition. A plurality of supports (15) mounted for fixing an air injection hole plate (38) to the combustor (2) are provided at substantially the same phase position as that of cross fire tubes, and combustion air allocations are adjusted. Thus, flame propagation during gas turbine ignition is accelerated and all combustor cans are fired. In addition, porous plates are disposed downstream of the supports (15) and the combustion air allocations are readjusted. Furthermore, air injection holes (32) proximate to the cross fire tubes are particularly reduced in diameter to further adjust the combustion air allocations. |
