Abstract:
An exhaust gas recirculation type gas turbine apparatus comprising; a compressor for compressing air; a combustion chamber for burning compression air exhausted from said compressor and fuel; a gas turbine driven by gas turbine exhaust gas from said combustion chamber; a recirculation path for recirculating a part of said gas turbine exhaust gas to an intake of said compressor; a recirculation amount control unit for adjusting an amount of gas turbine exhaust gas to be returned to the intake of said compressor corresponding to a change in load of said gas turbine; a spray unit for introducing liquid droplets into an interior of said compressor in which mixing gas, comprising gas turbine exhaust gas passing through said recirculation path and air flows so as to vaporize the introduced liquid droplets during a flow in said compressor; and a spray amount control unit for controlling a spray amount of said liquid droplets corresponding to said recirculation amount.
