Title: METHOD FOR MODIFYING A TURBINE
Abstract:
The invention relates to a method for modifying a turbine (1) with rotor blade rings (3a, 3b, 3c, 3d) and guide vane rings (4a, 4b, 4c, 4d) arranged in a conical housing (2), in which an original rotor blade ring (3a, 3b, 3c, 3d) at a first rotor blade position (I) is replaced by a replacement rotor blade ring (3’) at a second rotor blade position (II), wherein the second rotor blade position (II) is arranged spaced apart from the first rotor blade position (I) along a direction of extent of a rotor shaft (11) of the turbine (1) in the flow direction (S) of a working medium flowing through the turbine (1).
