PURPOSE: To supply appropriate liquid fuel for next starting, by using a separately- installed air compressor to purge residual liquid fuel out of a fuel nozzle in the trip of a gas turbine.
CONSTITUTION: When a gas turbine stops due to some trouble, a circuit for a shut- off signal 5 acts to entirely close a shut-off valve 2 to stop supplying liquid fuel. At that time, an air compressor 1 is started by the same shut-off signal 5 from a branch line to inject compressed air into a fuel passage 9 and a fuel nozzle 1 to purge residual liquid fuel out of the passage and the nozzle.
