Method for operating a gas turbine with axial thrust balance

The method involves configuring a gas turbine (4) with respect to aerodynamic forces and compressive forces, which exert axial forces on a turbine rotor such that the forces result in a negative thrust during no-load operation and low partial load and in a positive thrust during high load and full l...

More Information
Summary:The method involves configuring a gas turbine (4) with respect to aerodynamic forces and compressive forces, which exert axial forces on a turbine rotor such that the forces result in a negative thrust during no-load operation and low partial load and in a positive thrust during high load and full load to apply a positive-auxiliary thrust. An axial bearing force is positively held in an entire load area. Uncompressed air in high load area is utilized for pressurization. The auxiliary thrust is produced by controlling pressures at a front side or at a partial surface of the rotor.
