Abstract
A steam turbine apparatus is disclosed. In one embodiment, the steam turbine apparatus comprises: an exhaust shell portion including: a first section having a semi-circular cross-section; an exhaust section contiguous with the first section, the exhaust section including an intermediate-pressure exhaust outlet; and a second section having an oblate spherical cross-section including a substantially flattened portion, the second section configured to fluidly connect with the first section, wherein the first section and the second section form a continuous steam flow path.
