  • Publication number: 20040231334
    Abstract: A gas turbine has a cooling air system supplying air for cooling a high temperature part of the gas turbine and a spray air system supplying air for spraying fuel into a combustor and is formed so that a part of high-pressure air compressed by a gas turbine compressor is used as air of the cooling air system and spray air system, wherein a heat exchanger and a boost compressor are arranged downstream of the outlet of compressed air of the gas turbine compressor, and the boost compressor is composed of a parallel connection of a compressor driven by the turbine shaft and ae compressor driven by a driven source other than the turbine shaft, and pressurized air from the boost compressor is used as air for the cooling air system and the spray air system.

  • Patent number: 6143437
    Abstract: A vapor deposition material which is a molded body composed of powdery zirconia and a stabilizer, the molded body having a fine structure constituted of a mixture of granules of zirconia particles and non-granulated particles; granules of particle diameter ranging from 20 to 300 .mu.m constitute 20 to 90% of the molded body; the granules of the zirconia particles containing substantially no stabilizer, and being constituted of crystals of a monoclinic phase and a cubic phase with a ratio of the monoclinic phase of 70% or higher; and the particles constituting the granules having an average particle diameter from 0.5 to 15 .mu.m. A process for vapor deposition which employs the above vapor deposition material, and further a member is provided of a base article coated directly, or with interposition of a third film, with a thin zirconia film.
