Gas turbine combustor structure

A supercritical CO2 gas turbine which uses supercritical CO2 for a working fluid, comprising:

• a turbine casing;
• a turbine rotor penetrating horizontally through the turbine casing;
• a combustor structure penetrating the turbine casing perpendicularly to an axial direction of the turbine rotor from a vertically upper side of the turbine casing or a vertically lower side of the turbine casing;
• and
• a combustor casing fixed on the turbine casing perpendicularly to the axial direction of the turbine rotor at the vertically upper side or the vertically lower side, the combustor casing surrounding the combustor structure, the combustor casing being constituted by a cylindrical casing with a central axis perpendicular to the axial direction of the turbine rotor;
• the combustor structure comprising:
• a plurality of combustors enclosed within the combustor casing, the plurality of combustors being arranged circumferentially around the central axis of the combustor casing,
• each combustor of the plurality of combustors comprising:
• a combustor liner in a cylindrical shape, which combusts fuel and an oxidant, the combustor liner having a center axis which is perpendicular to the axial direction of the turbine rotor;
• a fuel supply provided at an upstream end of the combustor liner, the fuel supply being configured to supply the fuel into the combustor liner;
• and
• an oxidant supply provided at the upstream end of the combustor liner, the oxidant supply being configured to supply the oxidant into the combustor liner.
