Abstract
An apparatus can be arranged and configured so that after a gas turbine is shut down due to a detected condition, a higher autoignition temperature fuel can be utilized to purge a fuel delivery system and facilitate a quicker restart of the turbine. Embodiments can utilize conduits, valves, and a control system for detection of a fault condition warranting a shut down, purging of a lower autoignition temperature fuel via venting and use of a higher autoignition temperature fuel for purging to facilitate subsequent restarting of the turbine. Embodiments can be configured so an inert gas purge is not needed for venting and purging of the fuel delivery system.
