Condenser neck between a steam turbine and a condenser

Abstract

A condenser neck ( 1 ) comprises two level cover plates ( 2 ) and two side walls ( 3 ) located between them that are favorably shaped with respect to flow technology. The cover plates ( 2 ) and side walls ( 3 ) may be reinforced with ribs ( 4 a ,4 b ). A pipe ( 5 ) arranged between the cover plates ( 2 ) further reinforces the condenser neck ( 1 ). It would also be conceivable to provide openings ( 11 ) for bypass lines in the pipe ( 5 ) and/or in the side walls ( 3 ).

What is claimed is:  
     
         1 . Condenser neck ( 1 ) provided between a steam turbine and condenser, used to feed steam from the steam turbine to the condenser and provided with an inlet opening ( 9 ) and an outlet opening ( 10 ), 
 characterized in that    the condenser neck ( 1 ) comprises two level cover plates ( 2 ) and two side walls ( 3 ) widening in the flow direction of the steam ( 6 ), said side walls being favorably shaped with respect to flow technology.    
     
     
         2 . Condenser neck ( 1 ) as claimed in  claim 1 , 
 characterized in that    at least one of the cover plates ( 2 ) and/or at least one of the side walls ( 3 ) is reinforced with ribs ( 4   a ,  4   b ).    
     
     
         3 . Condenser neck ( 1 ) as claimed in  claim 1  or  2 , 
 characterized in that  
 a pipe ( 5 ) is provided between the cover plates ( 2 ).  
 
     
     
         4 . Condenser neck ( 1 ) as claimed in  claim 3 , if the latter is dependant on  claim 2 , 
 characterized in that    the ribs ( 4   a ) of the at least one cover plate ( 2 ) are arranged in star shape around the pipe ( 5 ).    
     
     
         5 . Condenser neck ( 1 ) as claimed in  claim 3 , 
 characterized in that    the pipe ( 5 ) is arranged centered between the cover plates ( 2 ) between the side walls ( 3 ) in the back third towards the outlet opening ( 10 ).    
     
     
         6 . Condenser neck ( 1 ) as claimed in one of  claims 1  to  5 , 
 characterized in that  
 openings ( 11 ), into which a bypass line merges, are provided in at least one cover plate ( 2 ) and/or in at least one side wall ( 3 ) and/or the pipe ( 5 ) located between the cover plates ( 2 ).  
 
     
     
         7 . Condenser neck ( 1 ) as claimed in one of  claims 1  to  6 , 
 characterized in that  
 connecting surfaces ( 7 ) are provided at the inlet opening ( 9 ), laterally towards the side walls ( 3 ).  
 
     
     
         8 . Condenser neck ( 1 ) as claimed in  claim 7 , 
 characterized in that    the condenser neck ( 1 ) is used with an axial arrangement of steam turbine and condenser.
