Abstract
An exhaust system for a double flow steam turbine providing a separate external exhaust path from an upper section of a turbine outlet of a first turbine section to a first condenser and a separate external exhaust path from a lower section the turbine outlet of the first turbine section to the first condenser. A separate external exhaust path from an upper section of a turbine outlet of a second turbine section and a separate external exhaust path from a lower section of the turbine outlet of the second turbine section is also provided.
