Abstract (en)
The steam turbine installation includes an expansion section connected to a steam generator and in which stationary guide vanes direct steam to rotating blades fitted on a turbine shaft. The guide vanes (142) have a hollow profile (57) and form a pressure side wall (53) forming the guide surface, and a rear suction side wall (55). A bleed tapping is formed by a slot (154) which is located in the region of the suction side wall of the guide vane.
