Gas turbine engine system

摘要

A gas turbine engine system (1) is provided with a gas turbine engine (2), a purge gas supply line (4) connected to a first connecting part (P1) of a fuel supply line (3) leading to the gas turbine engine (2), a fuel diffusion line (7) connected to a second connecting part (P2) downstream of the first connecting part (P1) of the fuel supply line (3), a blow-off valve (72) provided to the fuel diffusion line (7), and a channel-switching device (50) for switching the fuel supply line (3) between a fuel supply mode and a purge mode. A check valve (73) and a flame arrester (74) are provided downstream of the blow-off valve (72) of the fuel diffusion line (7).
