摘要： According to an embodiment, at least one first outer ring has an annular outer ring cavity to which external cooling steam is supplied. A radial direction cooling hole connecting with the outer ring cavity is formed in the stator blades connected to the first outer ring. An annular inner ring cavity connecting with the radial direction cooling hole is formed in a first inner ring constituting one diaphragm together with the first outer ring. Cooling steam blowing holes connecting an annular wheel space and the inner ring cavity are formed. The annular wheel space is formed between the first inner ring and a rotor wheel adjacent to the first inner ring.

摘要： A hydrogen-combustion gas turbine plant includes a first system for using inert gas as a working fluid, and a second system for using steam as a working fluid. The first system includes a compressor on a turbine shaft, a first heat exchanger, and a second heat exchanger. The first heat exchanger heats gas compressed by the compressor and supplies the compressed gas to a high pressure intake of a second turbine. The second heat exchanger cools gas exhausted from the second turbine and supplies the cooled gas to a low pressure intake of the compressor. The second system includes the first heat exchanger and the second heat exchanger. The first heat exchanger uses heat generated by combustion of a gas mixture including hydrogen and oxygen to heat the inert gas, and supplies steam resulting from the combustion to a high pressure intake of a first turbine. The second heat exchanger uses heat from the inert gas of the first system to heat steam exhausted from a low temperature outlet of the first turbine, and passes the heated steam to a third turbine.
