Abstract:
1. A gas turbine apparatus, comprising: a turbine; an air compressor rotatable integrally with said turbine; a recuperator for performing heat exchange between air compressed by said air compressor and an exhaust gas discharged from said turbine; a combustor for combusting a fuel mixed with the compressed air heated by said recuperator so as to produce a combustion gas which is supplied to said turbine to thereby rotate said turbine; and an outer tube, an intermediate tube, and an inner tube which are coaxially arranged, wherein an outer passage for the compressed air produced by said air compressor is formed between said outer tube and said intermediate tube, an intermediate passage for the compressed air heated by said recuperator is formed between said intermediate tube and said inner tube, an inner passage for delivering an exhaust gas from said turbine to said recuperator is formed in said inner tube, a connection passage is provided for delivering the compressed air from said outer passage to said recuperator; an introduction pipe extending through said outer tube to said intermediate passage is provided for delivering the compressed air heated by said recuperator to said intermediate passage, and an annular guide plate for guiding the compressed air to said connection passage is provided in said outer passage in a position upstream of said introduction pipe.
