Abstract
A centrifugal compressor includes a casing body (11) configured to rotatably support a rotation shaft (2) and an impeller (3) fixed to the rotation shaft around an axis (O), the casing body in which an intake volute (B1) which has a ring shape centered on the axis and through which a processing gas (G) is caused to flow in a direction of the axis and is introduced into a flow channel of the impeller, and a discharge volute which has a ring shape centered on the axis and through which the processing gas is discharged from the flow channel are formed; and a plurality of intake nozzles (16) which communicate with the intake volute and are able to cause the processing gas to flow into the intake volute from the outside and are provided at intervals in a circumferential direction around the rotation shaft.
