ABSTRACT:
In a method for degassing make-up water for a water-steam-circuit of a steam turbine process make-up water is introduced at a location of introduction into an exhaust steam pipe of the steam turbine so as to form a water film. A connector of the exhaust steam pipe is positioned in the vicinity of the location of introduction and connected to an evacuating device. The gases released from the make-up water are removed via the connector and the evacuating device. The device for performing the method has an exhaust steam pipe with an inner wall and free ends. At least one overflow trough including a deflecting shield is connected to the inner wall of the exhaust steam pipe. Closure plates are connected to the free ends of the exhaust steam pipe. The deflecting shield, the closure plates, the inner wall, and the overflow trough delimit a chamber having an opening toward the interior of the exhaust steam pipe only at the lower free edge of the deflecting shield.
