Abstract: A device is provided for the mutual fixing of two components, which are interconnected via a flanged joint, for preventing a relative movement of the components in relation to each other in the connecting plane of the flanged joint. The device includes a key which engages in both components in a form-fitting manner in the region of the flanged joint. A simplified and flexible application is achieved by the key being guided in one of the components by means of a precision fit, whereas in the other of the components the form fit can be adjusted by adding shims.

Abstract: A method is provided for adjusting the position of a rotor of a turbine. The turbine includes a first casing and a second casing. The second casing, in a bearing region of the rotor, has a fixed relative position, with regard to a rotor end, and is screwed to the first casing via a threaded connection. The method includes releasing the threaded connection; adjusting the relative position of the rotor to the first casing, which encloses the rotor in the flow region, by the relative position of the second casing to the first casing being adjusted; and refastening the threaded connection. Furthermore, a gas turbine or a steam turbine with such a device for adjusting the relative position of rotor and casing is also described.

Abstract: A gas turbine arrangement includes a compressor, a combustion chamber and a turbine connected to one another. A casing housing the compressor has flanges connectable to pipes providing secondary air to at least one of the combustion chamber and the turbine. The flanges define passages having an asymmetric cross section. A method for retrofitting a gas turbine arrangement is also provided.
