    • PURPOSE: A gas turbine and the liquid fuel purge system are provided to simplify a purge system, to facilitate a repair work of the purge system, and to obtain reliability in the system. CONSTITUTION: A gas turbine comprises: a main compressor, a combustor(118) and a turbine; a liquid fuel supply coupled to provide liquid fuel to the combustor; a gaseous fuel supply coupled to provide gaseous fuel to the combustor; and a liquid fuel purge system. The liquid fuel purge system comprises: a purge manifold; a coupling(202) to a compressor air discharge port of the main compressor to draw compressor air into the purge system; a conduit between the discharge port and the purge manifold through passing compressor air to the purge manifold, and a valve(400) alternatively coupling the manifold and liquid fuel supply(272) to the combustor. The valve includes an actuator coupled to the fuel supply, and the valve has a purge setting in which purge air passes through the valve to the combustor and a liquid fuel setting in which liquid fuel passes through the valve to the combustor. The valve is switched to the fuel setting by liquid fuel pressure applied to the actuator. When the turbine is switching to burn gaseous fuel, the liquid fuel remaining in the liquid fuel system is flushed by purge air provided by the liquid fuel purge system.
    • 目的:提供燃气轮机和液体燃料净化系统,以简化吹扫系统,便于清洗系统的维修工作,并获得系统的可靠性。 构成:燃气轮机包括:主压缩机,燃烧器(118)和涡轮; 耦合以向燃烧器提供液体燃料的液体燃料供应; 连接到气体燃料供应燃料的气体燃料; 和液体燃料净化系统。 液体燃料净化系统包括:净化歧管; 与主压缩机的压缩机空气排放口连接(202),以将压缩空气抽入吹扫系统; 通过使压缩机空气通过净化歧管而在排出口和净化歧管之间的导管以及将歧管和液体燃料供应(272)交替地连接到燃烧器的阀(400)。 阀包括联接到燃料供应器的致动器,并且阀具有吹扫设置,其中净化空气通过阀通过燃烧器和液体燃料设置,液体燃料通过阀通过燃烧器。 通过施加到致动器的液体燃料压力将阀切换到燃料设定。 当涡轮机切换燃烧气态燃料时,残留在液体燃料系统中的液体燃料被液体燃料净化系统提供的吹扫空气冲洗。
