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

A gas turbine moving blade, which has a blade root section, a wing section, and a platform section, comprises a refrigerant supply port provided in the blade root section, a refrigerant recovery port provided in the blade root section, a serpentine passage provided in the wing section and communicating with the refrigerant supply port and the refrigerant recovery port, and a convection-cooling passage provided in the platform section and allowing sealing air and a refrigerant for cooling the platform section by convection to pass therein.

Gas turbine moving blade

A steam cooled blade operating in a high temperature gas with a high cooling effect on a trailing edge portion has an impingement plate, disposed in the blade lengthwise direction within a trailing edge side cooling passage formed on a trailing edge side of a moving blade. The impingement plate partitions the trailing edge side cooling passage into a convection cooling steam passage, into which steam is introduced, and an impingement cooling steam passage, formed along a trailing edge of the moving blade. The steam cooled blade further has a by-pass passage 14 for joining the steam, after it is used for cooling the moving blade, flowing from a blade tip side of the impingement cooling steam passage with the steam flowing to a leading edge direction of the moving blade from the convection cooling steam passage.
