PROBLEM TO BE SOLVED: To obtain a gas turbine combustor in which generation of coking to a flame holder is prevented even when liquid fuel is used by pre-evaporation premix combustion system.;SOLUTION: Fuel jet nozzles 8 of the same number as the flame holders 7 are provided and arranged, in the radial direction, between the premixer outer tube wall 11 and the premixer inner tube wall 12 (in a premix combustion burner 10) and, in the circumferential direction, between two adjacent flame holders 7. Since each fuel jet nozzle 8 is arranged at a different position from the flame holder 7 in the circumferential direction, nonevaporating fuel can be prevented from adhering directly to the back face of the flame holder 7 (i.e., the flame holding face 7b) and carbonizing (coking) even if liquid fuel 32c for premix combustion is jetted and not evaporated sufficiently.;COPYRIGHT: (C)2002,JPO
