Abstract
An asymmetric butterfly plate for a steam turbine exhaust hood includes a non-symmetrical curvilinear profile having a first section that extends to a second section through a vertex. The first section has a first curvilinear profile and the second section has a second curvilinear profile that is distinct from the first curvilinear profile.
Claims20
An asymmetric butterfly plate for a steam turbine exhaust hood, the butterfly plate comprising:
- a non-symmetrical curvilinear profile having a first section that extends to a second section through a vertex, the first section having a first curvilinear profile and the second section having a second curvilinear profile that is distinct from the first curvilinear profile, the butterfly plate being configured and disposed to guide a fluid flow from an exhaust hood upper portion toward a condenser, the non-symmetrical curvilinear profile reducing fluid flow vortices to lower turbomachine efficiency loses.
A steam turbine exhaust hood comprising:
- an exhaust hood section;
- and
- an asymmetric butterfly plate arranged in the exhaust hood section, the asymmetric butterfly plate including a non-symmetrical curvilinear profile having a first section that extends to a second section through a vertex, the first section having a first curvilinear profile and the second section having a second curvilinear profile that is distinct from the first curvilinear profile.
A steam turbomachine system comprising:
- a turbine portion including an inlet section and an exhaust section;
- and
- an exhaust hood mounted to the exhaust section, the exhaust hood including:
- an exhaust hood section;
- and
- an asymmetric butterfly plate arranged in the exhaust hood section, the asymmetric butterfly plate including a non-symmetrical curvilinear profile having a first section that extends to a second section through a vertex, the first section having a first curvilinear profile and the second section having a second curvilinear profile that is distinct from the first curvilinear profile.
