Abstract:
Various embodiments include a steam turbine diaphragm nozzle segment, related assembly and steam turbine. Particular embodiments include a steam turbine diaphragm nozzle segment having: an airfoil having a contact surface for directing a flow of working fluid through a flow path; and a sidewall coupled with the airfoil and at least partially radially outboard of the airfoil, the sidewall having: a body contacting the airfoil; an axially upstream-extending hook extending axially from the body; a first notch adjacent the axially upstream-extending hook; an axially downstream-extending hook extending axially from the body; and a second notch adjacent the axially downstream-extending hook.
Abstract:
Various embodiments include a steam turbine nozzle and turbomachinery including such a nozzle. In various particular embodiments, a steam turbine nozzle includes: a body having: a first sidewall and a second sidewall opposite the first sidewall; a pressure side and a suction side each extending between the first sidewall and the second sidewall; and a leading edge section at a first junction of the pressure side and the suction side, and a trailing edge section at a second junction of the pressure side and the suction side; and a bypass fluid conduit including: a channel having an opening to at least one of the first sidewall or the second sidewall; and an outlet passageway fluidly connected with the channel between the first sidewall and the second sidewall, the outlet passageway including a first opening on at least one of the pressure side of the body, the suction side of the body or the trailing edge section.
Abstract:
Various embodiments include a turbomachine flow divider. In various particular embodiments, a flow divider for connecting with a first inner diaphragm ring and a second inner diaphragm ring of a turbomachine includes: a body section; and a pair of axially extending flanges extending from the body section, each of the axially extending flanges for engaging with the first inner diaphragm ring and the second inner diaphragm ring, respectively, wherein the flow divider is formed substantially of a rolled plate metal or a sheet metal.
