ABSTRACT:
A vertical shell-and-tube steam generator (10) which has a plurality of U-shaped tubes (60,62) through which the heating fluid flows, vaporizing fluid flowing on the outside of the tubes. A plurality of separators (26) are located above the tubes to remove liquid from the generated vapor. Orifices are located in some of the separator inlets (22) located above the hot leg region (60) of the U-tubes reducing the problem of overloading of these separators (26) by accomplishing a more uniform flow distribution of vapor from the areas above both the hot (60) and cold (62) legs of the U-tubes.
