Abstract

The invention relates to a gas turbine (10) having an exhaust gas diffuser (21) connected to a turbine unit (24) wherein the gas diffuser channel (33) of the gas diffuser is delimited on the outside by a channel wall (40) and is provided with a plurality of hollow supporting fins (35) extending inward for fastening a radial bearing (51) of the gas turbine (10) wherein at least one blow off line (47) for blow off air comprising at least one pipeline ends at the outlet side on the exhaust gas diffuser (21) and the end of the exhaust gas diffuser on the inlet side is connected to a compressor (18) of the gas turbine (10). In order to at least partially compensate for the incorrect incident flow of the supporting fins (35) more particularly in partial load operation it is proposed that the supporting fins (35) have a hub (48) on the inner end thereof the axial end of said hub being provided with additional openings (49) for blowing out the blow off air in the diffuser channel.
