Disclosed is a gas turbine enabling turn down operation, of which the system and the operation can be simplified, and also the production cost and the maintenance cost can be reduced. Specifically disclosed is a gas turbine comprising: a compressor section (2); a combustor section (3); a turbine section (4); a gas turbine casing which houses the compressor section (2), the combustor section (3), and the turbine section (4) therein; a stator cooling air system (5) for leading compressed air extracted from midstream of the compressor section (2) into stator vanes which constitute the turbine section (4); and an air bleeding system (6) for extracting compressed air from the exit of the compressor section (2) to the outside of the gas turbine casing, wherein midstream of the stator cooling air system (5) and midstream of the air bleeding system (6) are connected via a connecting path (12), and at midstream of this connecting path (12), there is a flow rate control part (13) connected. |
