STEAM GENERATOR WITH INTEGRATED REHEATER FED WITH LIQUID METAL

摘要

The steam generator shell contains a bundle of straight tubes, the upper portion of which constitutes the superheat zone. A cylindrical jacket surrounds the upper portion of the shell and defines an annular reheat space containing helical tubes connected to a bottom steam inlet header and to a top outlet header. The reheat space communicates with the interior of the shell through a lower set of windows and through an upper set of windows provided with a cylindrical valve for regulating the rate of flow.
