Title: INNER CASING STRUCTURE COMPRISING A CONDENSATION CHAMBER FOR A STEAM TURBINE
Abstract:
The invention relates to an inner casing structure (24) for a low-pressure turbine stage (7) in which a condensation chamber (40) is placed between a first bleeding chamber (35) and a second bleeding chamber (36), steam is supplied to the condensation chamber (40) from the first bleeding chamber (35), and the steam condenses in the condensation chamber (40), thus resulting in less thermal stress on the inner casing structure (24).
