| description | A method for safe gas turbine startup is disclosed. The method comprises a first step wherein a fuel metering valve (33) arranged along a fuel delivery line is tested for possible leakages. If the leakage test is successfully passed, a subsequent turbine startup step can be performed. Further disclosed is a gas turbine engine (3) comprising a fuel supply system (20) comprised of a fuel delivery line (21) and a valve arrangement (23) positioned along said fuel delivery line (21). The valve arrangement (23) further comprises sequentially arranged shut off valves (25, 29, 31) and a fuel metering valve (33), positioned downstream of the shut off valves (25, 29, 31). A pressure measuring arrangement (43, 45, 47) is further provided, adapted to measure fuel pressure in at least one portion of the fuel delivery line (21) upstream of the fuel metering valve (33). |
