Abstract
An arrangement and method adapted for providing a stiffened lower exhaust hood for a steam turbine. Sidewalls of the lower exhaust hood may taper inward between a horizontal joint and an inlet to a condenser for the steam turbine, providing an enhanced flow path for the exhaust steam. Stiffening of the sidewalls may be provided by stiffening bends, stiffening curvature, and external stiffening beams on the wall plate of the sidewalls of the lower exhaust hood, permitting reduction or elimination of structural supports within the exhaust hood, which degrade exhaust steam flow.
