ABSTRACT:
A gas turbine and an afterburner are operated with a dual liquid fuel system. During protective stops, logic controls are provided for initiating a transfer from operating fuel to a flushing fuel after predetermined conditions are satisfied. After fuel transfer, shutdown is completed without setting trips and restart can be achieved without special prestart preparation of the fuel system.
