Abstract
A method for safe gas turbine startup is disclosed. The method comprises a first step wherein a fuel metering valve () 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 () comprising a fuel supply system () comprised of a fuel delivery line () and a valve arrangement () positioned along said fuel delivery line (). The valve arrangement () further comprises sequentially arranged shut off valves () and a fuel metering valve (), positioned downstream of the shut off valves (). A pressure measuring arrangement () is further provided, adapted to measure fuel pressure in at least one portion of the fuel delivery line () upstream of the fuel metering valve ().
