摘要

The device (1) has steam inlet pipe (2) provided at one end of wall of the pressure vessel (4), while a steam outlet pipe (3) is provided at the opposite end of wall of pressure vessel. The water separation unit (5) is made flat and provided in the pressure vessel, such that steam inlet pipe side together with wall of the pressure vessel forms a tapered and closed distribution duct (V), for allowing passage of the incoming steam (D) completely through the water separation unit and superheating device (61,62).
