GAS TURBINE SYSTEM, AND COMBINED PLANT EQUIPPED WITH THE SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a gas turbine system more effective to obtain high efficiency and the reduced generation of an NOx and a combined plant equipped with the system. SOLUTION: This gas turbine system equipped with a compressor for combustion air, a combustor for combusting fuel by the air, and a gas turbine driven by high-temperature gas generated in the combustor, is constituted so as to circulate a part of exhaust gas exhausted from the turbine in the combustor; and the combined plant is equipped with the system.
