Abstract
A method for assembling an exhaust hood for a turbine is provided. The method includes providing a bearing cone that substantially circumscribes a rotor of the turbine; and positioning a guide radially outward from the bearing cone. The guide and the bearing cone are configured to channel fluid from the turbine. The method also includes extending a guide cap from the guide. The guide cap is oriented to facilitate preventing the generation of fluid vortexes within the exhaust hood.

A method for assembling an exhaust hood for use with a turbine including a plurality of stages, said method comprising:
- providing a bearing cone that substantially circumscribes a rotor of the turbine;
- positioning a guide radially outward from the bearing cone, wherein the guide and the bearing cone are configured to channel fluid from the turbine;
- and
- extending a guide cap radially outwardly from an edge of the guide, such that the intersection of the guide cap and the guide define an acute angle that forms an abrupt transition therebetween, wherein the guide cap is formed from a thin curved plate that is oriented to facilitate preventing fluid vortexes within the exhaust hood.
An exhaust hood for use with a turbine including a plurality of stages, said exhaust hood comprising:
- a bearing cone substantially circumscribing a rotor of the turbine;
- a guide positioned radially outward from said bearing cone, said guide and said bearing cone are configured to channel fluid from the turbine;
- and
- a guide cap extending radially outwardly from an edge of said guide, wherein an intersection defined between said guide cap and said guide defines an acute angle that forms an abrupt transition therebetween, wherein said guide cap is formed from a thin curved plate that is oriented to facilitate preventing fluid vortexes within said exhaust hood.
A steam turbine comprising:
- a rotor comprising a plurality of stages;
- and
- an exhaust hood configured to channel steam from a last stage of said plurality of stages, said exhaust hood comprising:
- a bearing cone substantially circumscribing said rotor;
- a guide positioned radially outward from said bearing cone;
- and
- a guide cap extending radially outwardly from an edge of said guide, wherein an intersection defined between said guide cap and said guide defines an acute angle that forms an abrupt transition therebetween, wherein said guide cap is formed from a thin curved plate that is oriented to facilitate preventing fluid vortexes within said exhaust hood.
