GAS TURBINE SYSTEM AND COMBINED PLANT COMPRISING THE SAME

摘要

Gas turbine system and combined plant comprising same provide higher effect in realizing high efficiency of plant and reduction of NOx generation. The gas turbine system comprising compressor (1) for compressing combustion air, combustor (2) for burning fuel with the combustion air and gas turbine (3) driven by high temperature gas generated at the combustor (2) is constructed such that portion of exhaust gas discharged from the gas turbine (3) is circulated into the combustor (2). The combined plant comprising the gas turbine system is also provided.
