A turbine comprising:
- a turbine vane carrier having an inner circumferential surface to which a plurality of turbine vanes are coupled;
- a turbine casing having an inner portion on which the turbine vane carrier is mounted, the turbine casing being provided with a cooling air inlet configured to supply cooling air towards the turbine vane carrier;
- and
- a guide baffle mounted on an outer circumferential portion of the turbine vane carrier and configured to guide the cooling air supplied through the cooling air inlet to an outer circumferential surface of the turbine vane carrier.
A gas turbine comprising:
- a compressor configured to compress external air;
- a combustor configured to mix fuel with air compressed in the compressor to combust a mixture thereof;
- a turbine having a turbine casing in which a plurality of turbine blades and a plurality of turbine vanes are mounted, the plurality of turbine blades being rotated by a combustion gas discharged from the combustor;
- a turbine vane carrier having an inner circumferential surface to which the plurality of turbine vanes are coupled;
- the turbine casing having an inner portion on which the turbine vane carrier is mounted, the turbine casing being provided with a cooling air inlet configured to supply cooling air towards the turbine vane carrier;
- and
- a guide baffle mounted on an outer circumferential portion of the turbine vane carrier and configured to guide the cooling air supplied through the cooling air inlet to an outer circumferential surface of the turbine vane carrier.
