    • The present invention provides a purge system for a gas turbine, the gas turbine comprising a compressor (1), a combustion chamber (2), at least one burner (3) and a gas fuel system, characterized in that the purge system comprises: a cooler (9) having an inlet end and an outlet end, a first pipeline (13) connecting the compressor (1) to the inlet end of the cooler (9), and at least one second pipeline (14) connecting the outlet end of the cooler (9) to a gas fuel supply pipeline (5, 6) of the gas fuel system, so that when the gas fuel system is at least partially closed, air from the compressor (1) can purge the gas fuel supply pipeline (5, 6) and burner (3) in the closed part of the gas fuel system after being cooled in the cooler (9). The present invention also provides a gas turbine system having the purge system and a method for purging a gas fuel system of a gas turbine.
    • 本发明提供了一种用于燃气轮机的吹扫系统,该燃气轮机包括压缩机(1),燃烧室(2),至少一个燃烧器(3)和气体燃料系统,其特征在于,所述吹扫系统包括: 具有入口端和出口端的冷却器(9),将压缩机(1)连接到冷却器(9)的入口端的第一管道(13)和连接出口端 的冷却器(9)连接到气体燃料系统的气体燃料供应管线(5,6),使得当气体燃料系统至少部分关闭时,来自压缩机(1)的空气可以吹扫气体燃料供应管线 (5)和燃烧器(3)在冷却器(9)中被冷却之后在气体燃料系统的封闭部分中。 本发明还提供一种具有吹扫系统的燃气轮机系统和用于清除燃气轮机的气体燃料系统的方法。
