PROBLEM TO BE SOLVED: To provide a gas turbine combustor capable of obtaining stable flame in a combustor by facilitating the evaporation of liquid fuel and mixture with combustion air in a preevaporation and premixing device by suppressing the deposition of coking in the preevaporation and premixing device installed at the gas turbine combustor. SOLUTION: The gas turbine combustor is provided with a fuel nozzle for jetting the liquid fuel, the preevaporation and premixing device for preevaporating the liquid fuel jetted from the fuel nozzle, mixing with the air for combustion, jetting and burning the generated premixed air to a combustion chamber on a downstream side, and a combustion chamber for burning the premixed air formed in the preevaporation and premixing device. A flame stabilizer inclining to the combustion chamber is arranged at the outlet side of the preevaporation and premixing device. A plurality of grooves or a plurality of holes are formed at the flame stabilizer. COPYRIGHT: (C)2009,JPO&INPIT
