Abstract

A pair of steam turbine inlet ports are disposed at opposite sides of a steam turbine housing for flowing steam in opposite circumferential directions in a generally annular steam chamber to first stages of a turbine through axially opposite outlets. Portions of the chamber in the upper and lower housing have decreasing cross-sections in a generally circumferential direction away from the steam inlet portions to provide a substantially uniform flow of steam about the chamber in a generally radially inward direction and about and through the axial outlets.
