Pilot fuel injected from fuel injection portsof a pilot nozzlebumps against an inner wall surface of a tapered portion of an inner circumference of a coneof a pilot cone. At this time, the position where a pilot fuel from the fuel injection portshits is located in a range from a middle of the tapered portion of the inner circumference of a coneto a downstream-side tip thereof.

Installation structure of pilot nozzle of combustor

Liquid fuel purge device uses water, not compressed air as in the prior art, thereby prevented are rapid load change of gas turbine due to sudden discharge of liquid fuel and coking of remaining liquid fuel. Upon supply of liquid fuel to fuel nozzle (,) being stopped, water purge system (,) having stop valve (,) supplies water into fuel system including liquid fuel system (,) and fuel nozzle (,) and liquid fuel remaining therein is purged by water into combustion chamber (,) from the fuel nozzle (,).
