Abstract
A shell and tube heat exchanger (2) having a vertical dam (50) surrounding one of the steam-water separators (26a), so as to create a low flow velocity or quiescent area where solids will settle out. The dam encircles an area seven times greater than the average area per-separator throughout the rest of separating deck, so that there is a low flow velocity. Also, an orifice (52) is positioned in the inlet to the dammed in separator, to further reduce the flow velocity. The settled out solids are removed from the steam generator through a blowdown pipe (60).
