Low-pressure turbine

Abstract

A double-flow low-pressure partial turbine is provided herein, wherein the exhaust steam of the first flow and the exhaust steam of the second flow are deflected in a common direction within the outer housing and thus axial outlet flow occurs.

1 . A low-pressure partial turbine, comprising
 a first flow and a second flow, a rotor mounted rotatably about an axis of rotation, an inner housing arranged around the rotor and an outer housing arranged around the inner housing,   wherein the low-pressure partial turbine is designed in such a manner that exhaust steam from the first flow which flows during operation through the low-pressure partial turbine flows substantially in the same direction as the exhaust steam from the second flow,   wherein the low-pressure partial turbine has a double-flow configuration and the exhaust steam from the first flow is deflected in the direction of the exhaust steam of the second flow, and   wherein the direction of the exhaust steam from the first flow and the direction of the exhaust steam from the second flow are oriented substantially parallel to the axis of rotation.   
     
     
         2 . The low-pressure partial turbine as claimed in  claim 1 , wherein the outer housing comprises a return steam chamber for returning the steam to the exhaust steam chamber of the second flow. 
     
     
         3 . The low-pressure partial turbine as claimed in  claim 1 , further comprising an annular chamber, which is arranged between the inner housing and the outer housing. 
     
     
         4 . The low-pressure partial turbine as claimed in  claim 1 , wherein the deflection is effected in the outer housing. 
     
     
         5 . The low-pressure partial turbine as claimed in  claim 1 , wherein the exhaust steam from the first flow and the second flow condenses in a condenser.
