Abstract

13,848. Brown, E. Hall-. June 10. Feed-water, heating. -A surface condenser is provided with means for separating oil and water from the entering steam in combination with means for bringing all or part of the steam into contact with all or part of the water of condensation in order to heat the water and to aid in the condensation of the steam. In one form of apparatus, Fig. 2, the steam enters the condenser a by an inlet b formed in a duct e extending from the top to the bottom of the condenser. The steam impinges on the wall of the duct e, and the oil and water thus separated fall into the well f. A further separation of water is effected by a tray k at the top of the condenser; the water thus collected falls through an aperture n and reaches the well f without being cooled by passage over the condenser tubes. A portion of the steam enters the condenser by the lower branch of the duct e, and is thus brought into contact with the water of condensation. A weir p having a hood q prevents oil from flowing away with the water. In another form of apparatus, Fig. 3, the steam enters by an inlet b, and, after the separation of the water in the duct t, passes through a port r and passage s to a chamber w in which it comes into contact with a spray of water of condensation derived from the weir p; the steam finally enters the condenser a by a passage y. The chamber w has perforated walls and is fitted with a spraying-device consisting of a convergent nozzle v having longitudinal slits z, together, it may be, with a splash-plate d.
