1. A gas turbine system comprising:
a compressor configured to compress a first external air to generate a compressed air;
a combustor configured to burn the compressed air together with a fuel to generate a combustion gas;
a turbine configured to be driven by the combustion gas;
an exhaust unit configured to guide the combustion gas that has passed through the turbine to an outside;
a shell having a cylindrical shape and extending along an axis line about which the turbine is configured to rotate, and being arranged so as to cover the compressor, the combustor, the turbine, and the exhaust unit;
a heat exchange unit configured to exchange a heat between the combustion gas that has passed through the turbine and a second external air on a surface of the shell, the heat exchange unit being configured to: (i) guide, to a plurality of discharge ports in the surface of the shell, the combustion gas that has passed through the turbine; and (ii) mix the combustion gas with the second external air to generate a mixed gas; and
an introduction unit configured to guide the mixed gas to the exhaust unit from a plurality of introduction ports in the surface of the shell,
wherein the discharge ports are defined in first portions, respectively, in a circumferential direction about the axis line,
wherein the introduction ports are defined in second portions, respectively, in the circumferential direction, and
wherein the discharge ports and the introduction ports are arranged at positions overlapping each other in the circumferential direction and aligned along the axis line and the shell is configured to guide the mixed gas to one of the introduction ports which is downstream of one of the discharge ports in a flow direction of the combustion gas and the second external air.
