Surface Condenser

—An apparatus for condensing steam, especially the exhaust of a steam engine, by bringing it into contact with metallic surfaces cooled on the other side by water or air; an oblong or circular metal box fitted with horizontal tubes; at each end are fixed the tube plates, K neraly made of bra , and the tubes pa through the plates as well as through a supporting plate in the middle of the condenser. Each end of the condenser is fitted with doors for the purpose of enabling the tube ends to be examined, drawn, or packed, as may be nece ary. The tube ends are packed in various ways, and the tubes are made of bra , so as to resist the action of the water. The water is generally forced through the tubes by the circulating pump, and the steam is condensed by coming in contact with the external surface of the tubes.
