A steam turbine having a low-pressure inner housing NDIG and a high-pressure inner housing HDIG within a steam turbine outer housing, a reheater downstream of the HDIG and upstream of the NDIG wherein the first steam inlet section of the HDIG faces the second steam inlet section of the NDIG, a process steam deflection section for deflecting process steam out of the first steam outlet section into a gap between an inner wall of the steam turbine outer housing and an outer wall of the HDIG and of the NDIG, a high-pressure sealing shell for sealing the upstream end-section of the HDIG, a low-pressure sealing shell for sealing the upstream end-section of the NDIG, the high-pressure sealing shell located adjacent to the low-pressure sealing shell, wherein process steam can be drawn from the HDIG and conveyed to a region between the high- and low-pressure sealing shells.

Steam turbine and method for operating same

A steam turbine, having a steam turbine outer housing; a high-pressure inner housing having first process steam inlet and outlet sections for conducting process steam therethrough from the inlet to the outlet section in a first process steam expansion direction; a low-pressure inner housing having second process steam inlet and outlet sections for conducting process steam therethrough from the second process steam inlet section to the second process steam outlet section in a second process steam expansion direction; and an intermediate superheater, which is arranged downstream of the high-pressure inner housing and upstream of the low-pressure inner housing, wherein the high-pressure and low-pressure inner housings are arranged within the steam turbine outer housing and the high-pressure and the low-pressure inner housings are arranged in such a way that the first steam inlet section of the high-pressure inner housing faces the second steam inlet section of the low-pressure inner housing.

An outflow housing for a turbine section of a steam turbine. The outflow housing has an outflow housing wall, which surrounds a central drum chamber along a housing longitudinal axis, and a connection interface for connecting the outflow housing to a turbine housing of the steam turbine. A sealing device for sealing an end of the outflow housing, which end is arranged at the rear in the flow direction, with respect to a turbine shaft of the steam turbine is arranged on the outflow housing wall, wherein the sealing device is sealed to the outflow housing wall. A steam turbine has the outflow housing herein.

Outflow housing of a steam turbine

A steam turbine having a turbine housing which has a plurality of turbine housing parts and surrounds a flow space along a turbine longitudinal axis, the turbine housing having a housing wall, a join being formed between two adjacent turbine housing parts. On a side of the housing wall facing the flow space, there is at least one flow shield which shields a wall section of the housing wall from a flow in the flow space. An interstice is formed between the flow shield and the wall section of the housing wall. The interstice has, at least in one region, an opening to the flow space, a fluid-communicating connection of the interstice to the flow space being formed via the opening.
