Abstract
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.
