The rotor () of a gas turbine containing a compressor part () and a turbine part () is mounted in an axial thrust bearing () and in two radial journal bearings (). One of the bearings is a journal bearing () arranged in the intake area of the compressor part () and the other journal bearing () together with the thrust bearing () is arranged in the area of the turbine part ().

Mounting of the rotor of a gas turbine

The removal of cooling air from the diffuser part of a radial end stage of a compressor of a gas turbine is provided. Compressed air is removed via a cooling air discharge (10) from a radial compressor stage, which comprises a rotor disk (2) and a bladed diffuser (20). The removal of cooling air may be brought about such that the cooling air is removed on one side through openings (6) on the housing side (20.1) of the diffuser (20) and is fed through cooling air channels (10) to the parts in contact with hot gas, including the outer wall of the bifurcated tube (17). The compressed air is guided to the diffuser outside (20.2) through cooling air holes (19) in the diffuser blade (3).
