Abstract
An arrangement and method adapted for providing a reinforced lower exhaust hood for a steam turbine. Double-wall sidewalls and endwalls for a lower exhaust hood include an outer corrugated wall joined to an inner plate wall. The enhanced strength provided by the corrugation provides reduced deformation of the lower exhaust hood and allows reduction of structural complexity and improved aero-performance within the lower exhaust hood.
