    摘要: An operation control method for a gas turbine includes making a molten salt map of molten salt for causing high-temperature corrosion on high-temperature components of the turbine due to impurities using a thermodynamic equilibrium calculation on the basis of the impurities contained in low-quality fuel and operation data of the gas turbine, indicating a surface temperature and a pressure of the high-temperature components of the turbine on the molten salt map , predicting a lifetime of the high-temperature components of the gas turbine by estimating a corrosion rate thereof, and controlling the flow rate of the low-quality fuel supplied to a combustor so that an area of surface temperature and pressure regions of the high-temperature components superposing on the region of molten salt in the liquid phase on the molten salt map is reduced.

    摘要: A hydrogen-resistant high strength material made of a Ni-based alloy or an Fe—Ni-based alloy includes an aged portion and a hydrogen embrittlement suppressing layer that is to be exposed to hydrogen. The hydrogen embrittlement suppressing layer has a hydrogen embrittlement index of not less than 0.9, wherein the hydrogen embrittlement index is defined as a ratio of an elongation after hydrogen charging in relation to an elongation before hydrogen charging. The aged portion has a tensile strength exceeding 1000 MPa.
