Abstract: PROBLEM TO BE SOLVED: To provide a liquid fuel purge system for washing a liquid fuel away from a combustion chamber for a gas turbine. SOLUTION: The liquid purge system includes the liquid fuel and a three-way valve for the flow of a purge air instead thereof to the combustion chamber. The gas turbine can be operated by the liquid fuel or a gas fuel. When the turbine is changed over for burning the gas fuel, the liquid fuel residing in the liquid fuel system is washed away by the purge air supplied by the liquid fuel purge system.
