FUEL SUPPLYING DEVICE FOR COMBUSTION EQUIPMENT

PROBLEM TO BE SOLVED: To restrain the generation of fume or the like while improving restarting by cutting a fuel path during the operation to make a fuel jetting valve communicate with a fuel pump and interrupting the communication between the fuel jetting valve and the fuel pump to make the fuel jetting value communicate with a fuel tank at the stopping of the operation. SOLUTION: During the operation (during the supply of a fuel) of a gas turbine 1, a fuel path 16 is cutoff while the communication position of an internal path is switched so that a fuel jetting valve 10 communicates with a fuel pump 11 to supply a fuel to the fuel jetting valve 10. At the stopping of the operation (during the cutting off of the fuel), the communication between the fuel jetting valve 10 and the fuel pump 11 is interrupted while the communication position of the internal path is switched so that the fuel jetting valve 10 communicates with the fuel tank 12 through the fuel path 16 to stop the supply of the fuel to the fuel jetting valve 10. The switching of the communication position of the internal path as mentioned above is performed by a switching operation of a fuel cutoff three-way valve 90 based on a signal from a control unit 20.
