Abstract

22,588. Morison, D. B. Oct. 13. [Cognate Application, 3785/12.] Feed-water, heating.- Apparatus for using exhaust steam, as from auxiliary machinery, for heating feed - water is provided with means for separating oil &c. from the steam, and with devices whereby excess of steam escapes to the atmosphere or to a condenser. The exhaust steam passes by pipes b to a chamber a in which is an inclined perforated plate c with ridges surrounding the perforations. Below the plate c are rows of channelirons f in a staggered arrangement as shown in Fig. 4. The plate c and channels f slope downwards to a chamber e, at the bottom of which is a trap l from which water is removed at the bottom and oil at the top. From the chamber a, the cleansed steam passes by an opening t to the feed - heater. With the chamber a communicates a chamber w, Fig. 3, communicating through openings controlled by valves 3, 4 with a condenser and by openings controlled by valves 5, 6 with the atmosphere. The valves 3, 6 are controlled by hand and the valves 4, 5 by springs. The valve 4 can be prevented from opening by a nut 7. Engines which must not exhaust against a backpressure may exhaust through a second separator to the chamber into which the valves 3, 4 open. In this case the valves 3, 6 may be replaced by a single spring - controlled valve which can be held open.
