Zusammenfassung:	PURPOSE:To maintain a constant fuel gas pressure by installing a cut-off valve, reduing valve, and a pressure adjustor in succession into a fuel gas feeding pipe and installing a signal corrector onto the signal transmission line for the pressure adjustor and the reducing valve. CONSTITUTION:A cut-off valve 2, reducing valve 3, and a pressure adjustor 4 are arranged successively from the upstream side into a fuel gas feeding pipe 1 connected to a gas turbine package 12. a signal corrector 5 is installed onto the signal transmission line 13 for the pressure adjustor 4 and the reducing valve 3. The cut-off valve 2 is opened by a start signal 15, and the start signal 15 is input into the signal corrector 5, and the reducing valve 3 is throttle before the reducing valve 3 downstream side pressure increases. Therefore, sharp pressure increase can be prevented, and fuel gas pressure can be kept at constant value.
