PROBLEM TO BE SOLVED: To provide gas turbine equipment capable of suppressing drop of efficiency even if a casing thermally deforms. SOLUTION: The equipment is provided with an inner casing 17 arranged inside of a compressor casing 11 with a gap and forming a compressed air flow passage 16 in a space with compressor rotors 15A, 15B, and an inner casing 26 arranged in a turbine keeping a gap in a turbine casing 18 and forming a combustion gas flow passage between turbine rotors 24A, 24B. Since gap between the compressor rotors 15A, 15B, the turbine rotors 24A, 24B and each inner casing 17, 26 can be maintained almost constant during operation from start by the structure mentioned above even if the compressor casing 11 and the turbine casing 18 thermally deform, the gas turbine equipment capable of suppressing drop of efficiency can be provided.
