    Abstract: 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 (202) and directs the purge air to manifolds (206,234,236) which distribute air to the atomizing air passages, liquid fuel nozzles, and water injection nozzles via purge valves (222,224) and soft purge valves (252,253).

    Abstract: PROBLEM TO BE SOLVED: To dispense with a purge compressor by using low pressure air from a main compressor discharge port when a gas turbine is operated by gas fuel. SOLUTION: This purge system receives cooled and filtered air from a compressor discharge port 202 through an atomizing air pre-cooler 164 and a water separator 166. An atomizing air compressor bypass, line 210 supplies compressor discharge air to the purge system. The bypass line 210 enables manual control for the pressure and flow of the compressor discharge air supplied to the purge system as purge air. It is desirable to include a manual-operated regulating valve 212 and a limit orifice 211. The purge system does not require a boosting purge compressor so that the pressure of purge air is below the pressure of the compressor air from the discharge port 202.
