Abstract
A method of fabricating a steam turbine nozzle box is provided, wherein the method includes forming an annular chamber defined by a radially outer wall and a radially inner wall and coupling a plurality of inlets in flow communication with the annular chamber such that steam is discharged from each of the plurality of inlets into the chamber at an oblique discharge angle with respect to an inlet axial centerline.
