    摘要: A purge system is disclosed for flushing liquid fuel and water from the combustion section of a gas turbine system as well as for providing continuous cooling of the nozzles. The gas turbine may operate on liquid fuel or gaseous fuel. When the turbine is switched to burn gaseous fuel, the liquid fuel remaining in the liquid fuel system is flushed by a liquid fuel purge system. Similarly, water in the water injection system is purged from nozzles in the combustion system by a water purge system. The purge system operates in conjunction with an air atomization system, but does not rely on an atomizing air compressor to boost the pressure of the purge air. Instead, the purge system utilizes pressurized air from the gas turbine compressor and directs the purge air to manifolds which distribute air to the atomizing air passages, liquid fuel nozzles, and water injection nozzles via purge valves and soft purge valves.
