<P>PROBLEM TO BE SOLVED: To cut down fuel cost by reducing the use amount of starting fuel. Ž<P>SOLUTION: In an operating method of a gas turbine, a burner including a fuel nozzle for injecting fuel into a combustion chamber and an air nozzle for supplying combustion air to the combustion chamber is provided with a starting fuel supply system which supplies starting fuel employed for ignition and start-up of the gas turbine. When igniting the gas turbine, the starting fuel and fuel through the fuel nozzle are supplied to the combustion chamber. The supply of the starting fuel is stopped before the gas turbine reaches the no-load rotation speed. Therefore, the use amount of starting fuel is reduced to cut down the fuel cost.
