Guide blade assembly and method for fine tuning the swallowing capacity of such a guide blade assembly

摘要

The stator blade row has multiple stator blades (L) formed between blade channels (K), where the stator blades are distributed over an extent. One of the stator blades has a passage (B) for injecting steam (D) from interior of the stator blade. The steam has a pressure in the interior of the stator blade. An independent claim is also included for a method for fine adjustment of absorption capacity of a stator blade of a steam turbine.
