Abstract (en)

Coolant (51) such as air or water is circulated into a guide ring (21), facing the rubbing edge (35) of a rotor blade (15), prior to starting the axial flow fluid machine. The coolant circulation is halted once the machine is started, during which steam or hot air is circulated into the guide ring. Independent claims are included for the following: (1) a compressor; and (2) a device for adjusting radial clearance in an axial flow fluid machine.
