LIQUID FUEL SUPPLYING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To prevent the occurrence of a failure caused by an excessively high pressure in a fuel supplying structure which supplies liquid fuel from an oil tank to a combustor by utilizing a head. SOLUTION: In a fuel supplying structure in which a pressure reducing valve 4 and a shut-off valve 5 are connected to a fuel supplying pipe 3 connecting an oil tank 1 to a combustor 2 provided at a lower position than the tank 1, with the valve 5 being on the downstream side of the valve 4, a relief valve 17 is connected to the pipe 3 for relieving the fuel enclosed between the valves 4 and 5 when the valve 5 is closed to the upstream side of the valve 4. Therefore, the breakage of the valve 4 by the abnormal pressure rise of the fuel enclosed between the valves 4 and 5 can be prevented.
