Abstract (en)

[origin: EP2775096A2] The arrangement (60) has an annular wall (70) formed with a supplyable annular groove (72) and arranged along flow direction at a location of a moving blade collar (68) for introducing vapor into an annular gap (74) between the annular wall and the blade collar. An inlet end (64) of a diffuser (62) is extended along circumferential direction and axial direction against the flow direction. A flow guide lip (76) divides the vapor into a check steam flow at an external periphery of the blade collar and a boundary layer flow along the annular wall that is projected into the gap.
