摘要
There is provided an axial flow compressor 1 that improves reliability on an increase in a blade loading on a last-stage stator vane of the axial flow compressor 1 due to a partial load operation of a gas turbine 3. An annular flow passage is formed by a rotor having multiple rotor blades fitted thereto and a casing having multiple stator vanes fitted thereto, two or more of the stator vanes 35, 36, 37 are disposed downstream of a last-stage rotor blade that is the rotor blade disposed at the most downstream side in a flow direction of the annular flow passage, a blade loading on a first stator vane 35 disposed at the most upstream side is set to be smaller than a blade loading of a second stator vane 36 disposed downstream of the first stator vane 35 by one row.
