ABSTRACT:
In an axial flow turbine with a row of individually adjustable guide vanes (8) and a row of rotor blades (5), the guide vanes can be rotated by an adjusting shaft (9) supported in a casing (4) and passing through a vane carrier (3). The tips of the rotor blades seal against a cover (7). In order to match the duct contour to different heights of blading (5, 8), only the vane carrier (3) and the cover (7) are designed to be exchangeable, with otherwise unaltered machine geometry.
