Abstract
A turbine () of a turbine installation, especially a steam turbine of a steam turbine installation, includes at least one radial or diagonal turbine stage () with radial or diagonal inflow and axial outflow, and also at least one axial turbine stage (-) with axial inflow and axial outflow. The at least one radial or diagonal turbine stage () forms the first stage of the turbine () and the at least one axial turbine stage (-) is arranged downstream of the radial or diagonal turbine stage () as an additional stage of the turbine. The at least one radial or diagonal turbine stage () has a higher temperature resistance than the at least one axial turbine stage (-). The turbine () makes it possible to significantly increase the process temperature of the steam turbine installation, wherein measures for increasing the temperature resistance need only to be adopted for components of the radial or diagonal turbine stage ().
