In this type of compressor, air enters axially and leaves axially.
CONSTRUCTION :
The arrangement of axial flow compressor consists of casing, rotating drum, rotor blades and stator blades. The stator blades are fixed to the casing. The rotor blades are fixed on the rotating drum. The airflow passage area is gradually reduced from the inlet to the outlet of the compressor.
WORKING :
When the power is given to the compressor, the rotating drum rotates and it creates suction in the compressor. Due to the suction, air enters through the compressor inlet and passes through the rotor and stator blades. As the air flows from one set of stator and rotor to another, it gets compressed. The air is also compressed between the casing and the blades. Pressure of the air is further increased due to gradual decrease in area from the inlet to the outlet of the compressor. Finally, The air at a high pressure is delivered to the receiver.
APPLICATIONS :
The axial flow compressors are most suitable for large size gas turbine plants and high-pressure units
