54,095 ABSTRACT A method and apparatus for collection of water in a steam turbine exhaust system and in particular within a steam turbine exhaust pipe in which there is at least one turn or bend in the pipe and a plurality of substantially parallel turning vanes positioned in the bend for reducing undesirable flow characteristics in steam. The turning vanes extend across the pipe transverse to the direction of steam flow and are attached at opposite ends to a vane support ring embedded in the pipe wall. The invention includes forming a plurality of slots extending through the vane support ring for transporting water from within the pipe to an external location. The slots are aligned on the vane support ring in an area corresponding to virtually zero pressure differential between each of the vanes and an adjacent vane. The slots preferably extend from a trailing edge of one of the vanes along the line normal to a tangent line to an adjacent vane on the low pressure side of the vane.
