ABSTRACT:
A gas turbine apparatus is used in, for example, a power generation apparatus. The gas turbine apparatus according to the present invention includes a turbine, an air compressor rotatable integrally with the turbine, a recuperator for performing heat exchange between air compressed by the air compressor and an exhaust gas discharged from the turbine, a combustor for combusting a fuel mixed with the compressed air heated by the recuperator so as to produce a combustion gas, and an outer tube, an intermediate tube, and an inner tube which are coaxially arranged. An outer passage is formed between the outer tube and the intermediate tube, an intermediate passage is formed between the intermediate tube and the inner tube, and an inner passage is formed in the inner tube.
