US 2019/0292986 A1 · GAS TURBINE SYSTEM

Abstract

A gas turbine apparatus includes a first compressor, a combustor, and a first turbine. The first compressor compresses a working fluid. The combustor injects a fuel into the working fluid discharged from the first compressor and combusts the fuel. The first turbine expands combustion gas produced in the combustor. A bleeding cycle apparatus includes a second compressor and an expansion mechanism. The second compressor compresses the working fluid, extracted from the gas turbine apparatus, whose pressure has been raised by the first compressor. The expansion mechanism expands the working fluid discharged from the second compressor. A first heat exchanger performs a heat exchange between the working fluid compressed by the first compressor and to be expanded by the first turbine and the working fluid compressed by the second compressor and to be expanded by the expansion mechanism.

A gas turbine system comprising:

a gas turbine apparatus including a first compressor that compresses a working fluid, a combustor that injects a fuel into the working fluid discharged from the first compressor and combusts the fuel, and a first turbine that expands combustion gas produced in the combustor;
a bleeding cycle apparatus including a second compressor that compresses the working fluid, extracted from the gas turbine apparatus, whose pressure has been raised by the first compressor and an expansion mechanism that expands the working fluid discharged from the second compressor;
and
a first heat exchanger that performs a heat exchange between (i) the working fluid compressed by the first compressor and to be expanded by the first turbine and (ii) the working fluid compressed by the second compressor and to be expanded by the expansion mechanism.
