Abstract
A separator for separating water from a mixture of water and steam in which an elongated, outer, water scroll is concentrically spaced from an elongated, inner, steam scroll. One longitudinal edge of each scroll is connected to a girth baffle disposed adjacent the side of a steam drum, and both scrolls extend through semi-circular curves of 180.degree. in cross section. The steam scroll is covered through the first 90.degree. of its curve, and is provided with a longitudinally-elongated opening extending circumferentially the second 90.degree. of its curve. A perforated plate encloses the bottom of the steam scroll to form a longitudinal flow passage. The centrifugal action imparted by the 180.degree. curvature of the separator causes the water to sepate from the steam-water mixture introduced between the steam and water scrolls, to flow along the inner surface of the water scroll, and to discharge downwardly through perforated, water splash diffuser plates. The steam passes through the elongated opening in the steam scroll and through the longitudinal flow passage to discharge from the separator at both ends.
