Abstract: 15,794. Morison, D. B. July 15. Condensers ; exhaust, freeing from grease &c. - Relates to apparatus for cleansing and condensing steam and heating water, especially applicable for the treatment of the exhaust steam from steam winches and steering and other continuously - running auxiliary engines. The apparatus may also be employed for heating feedwater or sea-water for baths. A steam - separating chamber 2, provided with steamdistributing and oil and water separating and collecting devices, is in direct communication with the condensing - chamber, or the first of a series of communicating condensing - chambers 8, through a steam outlet passage or passages 7, which extend practically the entire length of the chamber 2. The chamber 2 and the chamber 8, which may be any type of surface or direct-contact condenser or heater, are embodied in one structure, as shown in Fig. 5. The passage between the separating and condensing chambers is preferably formed in a division wall common to the two chambers. The separating- chamber is fitted with a removable cover 4, on the inner surface of which are oil and water separating and collecting devices. As shown in Figs. 1 and 3, these consist of one or more upwardly-inclined division plates 10, above and below which are inclined zig-zag or straight grooves formed by ribs 14. When the cover is in position, these ribs bear against inclined division ribs 11 carried by the rear wall of the separating - chamber. Steam admitted by the inlet 3, which may be provided with distributing-plates, thus follows a zig-zag path on its way to the collecting-chamber 5. Part of the separated oil and condensed water is directed by the plate 14 to a transverse channel 15, which communicates by a passage 16 with the chamber 5. The oil and water are drawn off from the chamber 5, while the steam passes through the opening 7 and over the successive sets of water tubes 9 to the outlet 23. In a modification, applicable to apparatus for the treatment of dry steam, the cover is provided with hollow water channels 24, between which the drain channel 15 is located, as shown in Fig. 4. Figs. 6 and 8 show another arrangement, in which the steam flows in a horizontal direction through the chambers 2, 8, which communicate by a passage extending the length of the chamber 8. The chamber 2 is provided with separating and collecting devices, consisting of metal bars 28 of angular section, which are held in place by a top plate. The steam inlet 3 is fitted with inclined distributing-plates 3<a>. Where the auxiliary or winch condenser is not usually in use, as at sea, the exhaust steam may be passed through the apparatus on its way to the condenser of the main engines. The water supply is so arranged that the apparatus serves only as a cleanser. When used as a feedwater heater, the heated water of condensation may be drawn off from any compartment which is free from oil. If sea water passes through the water tubes of the condenser, it may be used as bath water. According to the Provisional Specification, the removable cover of the separating chamber may be provided with separating and collecting devices comprising rows of separate vertical baffle-plates which are inclined to the cover and rows of #-shaped baffling-devices. The lower edge of each of the guide-plates carried by the inner wall of the separating-chamber terminates between a row of inclined vertical baffleplates and the next adjacent lower row of angular baffles. The cover may also be formed in two parts. The outer portion may be in the form of a flat plate provided on its inner side with ribs extending into V or other shaped recesses of the inner part, so as to cause the water to follow a zig-zag path through the cover. Reference is made to Specification No. 2842, A.D. 1904.
