Optimized turbine stage of a turbine plant, as well as design of the method

摘要

A turbine (100) of a turbine engine is disclosed, in particular, a steam turbine for a steam turbine engine. The turbine comprises at least one radial or diagonal turbine stage (120) with radial or diagonal feed stream and axial exhaust flow and at least one axial turbine stage (121 - 125) with a axial feed steam and axial exhaust flow. The at least one radial or diagonal turbine stage (120) forms the first stage of the turbine (100) and the at least one axial turbine stage (121 - 125) is arranged downstream of the radial or diagonal turbine stage (121) as a further stage of the turbine. The at least one radial or diagonal turbine stage (120) has a higher temperature-resistance than the at least one axial turbine stage (121 - 125). The turbine (100) permits a significant increase in the process temperature of the steam turbine engine, whereby measures to increase the temperature-resistance need only be carried out on the components of the radial or diagonal turbine stage (120).
