A flow conditioner for a steam turbine inlet includes an annular ring adapted to seat in a flange portion of an inlet in a turbine casing and a pair of wing portions extending from the annular ring in a flow direction, away from the annular ring. A related method of smoothing flow through an inlet of a steam turbine inlet casing wherein the inlet includes a circular flange and a non-circular transition portion extending between the annular flange and a main body portion of the steam turbine casing includes the steps of a) identifying surface discontinuities that disrupt flow of working fluid through the steam inlet; b) providing a flow conditioner that is shaped to conceal one or more of the surface discontinuities; and c) inserting the flow conditioner into the inlet.

Steam turbine low pressure inlet flow conditioner and related method

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.

Steam turbine inlet and methods of retrofitting

A turbine shell assembly includes radially inner and outer shell components; axial alignment fits on the inner and outer shell components, each alignment fit comprising a male fit component on one of the inner and outer shell components and a female fit component on the other of the inner and outer shell components, the female fit component comprising a pair of flanges forming a U-shaped channel with opposed faces, and the male fit component comprising a projection received within the U-shaped channel; and a pair of axial alignment keys, each key having a mounting flange for securement along an outer edge of a respective one of the pair of flanges and an alignment flange engaged along a respective one of the opposed faces.
