Turbine condenser for a steam turbine

Abstract

A turbine condenser includes an area with condenser tubes for liquefying waste steam from the steam turbine, a chamber formed by condenser walls for receiving the waste steam, and a diverted steam channelling system for channelling diverted steam into the chamber in the turbine condenser, wherein the diverted steam channelling system includes an annular nozzle extending into the turbine condenser, the outlet end of which has an uneven edge.

1 . A turbine condenser for a steam turbine, comprising:
 a region with condenser tubes for the liquefaction of exhaust steam from the steam turbine, having a chamber, formed by condenser walls, for receiving the exhaust steam, and having a bypass-steam introduction device for introducing bypass steam into said chamber of the turbine condenser,   wherein the bypass-steam introduction device comprises a ring-shaped nozzle which extends into the turbine condenser, and the outlet end of which has a non-uniform edge.   
     
     
         2 . The turbine condenser as claimed in  claim 1 ,
 wherein the edge is in the form of a serrated or toothed outlet edge.   
     
     
         3 . The turbine condenser as claimed in  claim 2 ,
 wherein the edge has serrations or teeth distributed uniformly over the circumference.   
     
     
         4 . The turbine condenser as claimed in  claim 3 ,
 wherein the serrations or teeth of the edge are at least partially inclined in the axial direction of the nozzle.
