摘要

The multi-stage turbine has assembly levels arranged concentrically on a pivoted axis. The steam flow is guided from innermost blade ring to outermost blade ring in meandering manner.The steam flow is deflected between the single assembly level over channels introduced in the housing.The steam is introduced into the first assembly level by a ring of hundreds of nozzles, which is integrated in the housing wall.The exhaust steam is condensed in the secondary circuit of the condensation heat exchanger and transmitted in the primary circuit.
