Title: Method of manufacturing a plurality of steam turbines for use in various applications

Abstract: In a method of manufacturing a plurality of steam turbines for use in various applications which differ in the respective thermodynamic parameters such as, for example, cooling-water temperature, ambient temperature, given boiler data, process-steam requirement, etc., the steam turbines in each case having at least one high-pressure part with first blading and a control-wheel stage for part-load operation, a simplification and cost saving is achieved owing to the fact that standard blading, which is identical for all the steam turbines, is used as first blading, and in that the adaption of the individual steam turbine to the thermodynamic parameters of the respective application is carried out by appropriate design or variation of the control-wheel stage.
