Abstract
Described herein is a shell and tube vapor generator in which vaporizable liquid is evaporated and superheated within the same vessel. Downflow and upflow passages are provided for conducting the vaporizable liquid in heat exchange relation with the heating medium that is conducted through the tubes. The downflow passages into which subcooled feedwater is introduced are defined by a plurality of mutually spaced conduits disposed between the shell wall and the tube bundle. The arrangement permits the shell wall to be wetted by liquid at substantially saturated temperature throughout the evaporation region of the chamber thus to reduce the stresses within the tube material caused by thermal loading.
