PROBLEM TO BE SOLVED: To provide a fuel supply system for a gas turbine combustor capable of preventing overheating of fuel and coking in fuel system even when the fuel is supplied to the fuel system after exposure to high temperature air without letting the fuel to flow, and enhancing refining of fuel, improving combustion efficiency in a low rotation area, and capable of enhancing combustion stability. SOLUTION: The fuel supply system for the gas turbine combustor is provided with a double fuel pipe 12 comprising an inner pipe 12a supplying the fuel to the gas turbine combustor and an outer pipe 12b surrounding the inner pipe with an interval in between, a fuel circulation system 14 supplying the fuel to a gap between the inner pipe and the outer pipe from a fuel tank 11 and returning heated fuel to the fuel tank, and the fuel supply system 16 supplying one part of the heated fuel to the inner pipe.
