chamber 2 which is constructed in the style of an annular combustion chamber is equipped with a number of burners 110 for combusting a liquid or gaseous fuel the turbine unit 106 has a number of rotatable rotor blades 112 which are connected to the turbine shaft 108 the rotor blades 112 are arranged on the turbine shaft 108 in a ring like manner and therefore form a number of rotor blade rows furthermore the turbine unit 106 comprises a number of fixed stator blades 6 8 114 which are also fastened in a ring like manner on a stator blade carrier 1 of the turbine unit 106 forming stator blade rows the rotor blades 112 in this case serve for driving the turbine shaft 108 as a result of impulse transfer from the operating medium m which flows through the turbine unit 106 the stator blades 6 8 114 on the other hand serve for flow guiding of the operating medium m between two consecutive rotor blade rows or rotor blade rings in each case as seen in the flow direction of the operating medium m a consecutive pair consisting of a ring of stator blades 114 or a stator blade row and a ring of rotor blades 112 or a rotor blade row in this.
