Abstract: A raw material fluid treatment plant provided with a raw material reaction apparatus for reacting a raw material fluid to form a reaction gas. The raw material reaction apparatus includes preheaters and a reactor. The preheaters are heat exchangers that perform heat exchange between a second heat transfer medium and the raw material fluid to heat the raw material fluid. The reactor is a heat exchanger that performs heat exchange between a first heat transfer medium differing from the second heat transfer medium and the raw material fluid having been heated by the preheaters to heat and react the raw material fluid.

Abstract: An ammonia decomposition facility includes a heating medium line configured to flow a heating medium heated by heat generated by a gas turbine, an ammonia supply line configured to flow ammonia, an ammonia decomposition device, and an ammonia removal device. The ammonia decomposition device is configured to use heat of the heating medium from the heating medium line, thermally decompose ammonia from the ammonia supply line, and generate a decomposition gas containing hydrogen, nitrogen, and residual ammonia. The ammonia removal device is configured to remove the residual ammonia contained in the decomposition gas from the ammonia decomposition device.

Abstract: A gas turbine plant is provided with a gas turbine, a heating device, a decomposition gas line, and a decomposition gas compressor. The heating device heats ammonia and thermally decomposes the ammonia to convert the ammonia into decomposition gas including hydrogen gas and nitrogen gas. The decomposition gas line sends the decomposition gas PG from the heating device to the gas turbine. The decomposition gas compressor increases the pressure of the decomposition gas to a pressure equal to or higher than a feed pressure at which the decomposition gas is allowed to be fed to the gas turbine.

Abstract: There is provided a gas turbine (1) including a compressor (2) that generates compressed air, a casing (5) into which the compressed air is introduced, a combustor (3) that generates a combustion gas, a turbine (4) that is driven by the combustion gas, a combustor cooling system (6) that has a sub-compressor (62), which is able to be operated independently of the compressor (2), and a heat exchanger (61), which extracts air in the casing (5) and causes the air to exchange heat after the sub-compressor (62) has increased a pressure of the air, and that introduces the air, which has exchanged heat, into a cooling passage (31) of a cylindrical body (30) of the combustor (3), and a combustor air introducing system that extracts air flowing in the combustor cooling system (6) and introduces the air into the combustor (3).
