PROBLEM TO BE SOLVED: To provide a regeneration gas turbine system stabilizing speed rise to ignition rotation speed with flow rate windage point of a turbine avoided, and increasing turbine output in consequence in regeneration cycle gas turbine systems including centrifugal compressors, radial flow turbines and regeneration heat exchangers.SOLUTION: This gas turbine system includes a centrifugal compressor 2 sucking atmospheric air and generating compressed air, a combustor 5 generating combustion gas by mixing and burning the compressed air and fuel, a radial flow turbine 3 driven by the combustion gas, a regeneration heat exchanger 6 exchanging heat between exhaust gas discharged from the radial flow turbine 3 and the compressed air supplied to the combustor 5 from the centrifugal compressor 2, and a bypass conduit 9 leading the compressed air discharged from the centrifugal compressor 2 to the combustor 5 with the regeneration heat exchanger 6 bypassed. |
