ABSTRACT:
A mosture pre-separator for the exhaust from a steam turbine, having an exhaust nozzle, comprises three cylindrical conduits. A first cylindrical conduit is affixed to the annular wall of the nozzle and has a radially outwardly extending section adjacent the annular wall, with a second cylindrical conduit, which terminates short of the annular wall, contained therein to form a first collection chamber therebetween. A third cylindrical conduit is slidably positioned in the second cylindrical conduit and extends into the exhaust nozzle of the turbine and forms a second collection chamber between the outer wall thereof and the wall of the exhaust nozzle, with direct communication provided between the first and second chambers. The third cylindrical conduit may have flow directing plates at the upper terminus thereof which extend outwardly towards the wall of the exhaust hood to remove the water film formed thereon and direct the film to be second collection chamber and then from the second collection chamber to the first collection chamber for draining therefrom.
