INTER-STAGE STEAM SEPARATOR-SUPERHEATER APPARATUS FOR TURBINES OPERATING WITH SATURATED STEAM

摘要

An inter-stage steam separator-superheater apparatus whose separator is annular and whose multi-tube steam superheater is mounted inside the separator and coaxially therewith, the plurality of the helically coiled heat exchange tubes, extending along multiple helices, of the steam superheater, the steam to be superheated being directed into the spaces between this plurality of the helically coiled heat exchange tubes, and the heating steam being directed into these helically coiled heat exchange tubes.
