Gas turbine system and moving body including the same

A gas turbine system comprising:

• a compressor that compresses external air to generate compressed air;
• a combustor that burns the compressed air generated by the compressor together with fuel to generate a combustion gas;
• a turbine driven by the combustion gas generated by the combustor;
• an exhaust unit that guides a combustion gas that passed through the turbine to outside;
• a shell formed in a cylindrical shape and extending along an axis line about which the turbine rotates and arranged so as to cover the compressor, the combustor, the turbine, and the exhaust unit;
• a heat exchange unit that exchanges heat between the combustion gas that passed through the turbine and external air flowing on a surface of the shell, the heat exchange unit exchanging heat between a combustion gas and external air by guiding, to at least one discharge port provided in a surface of the shell, a combustion gas that passed through the turbine and mixing the combustion gas with external air;
• and
• an introduction unit that guides the mixed gas, in which the combustion gas discharged from the discharge port and external air are mixed, to the exhaust unit from at least one introduction port provided in the surface of the shell,
• wherein discharge ports each comprising the discharge port are provided to a plurality of portions in a circumferential direction about the axis line,
• wherein introduction ports each comprising the introduction port are provided to a plurality of portions in the circumferential direction, and
• wherein the discharge ports and the introduction ports are arranged at positions overlapping each other in the circumferential direction.
