Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1864 edition. Excerpt: ...But practically, there will be some leakage of the steam to be supplied from the sea, and some sediment to be blown off, both which will occasion a small demand for sea water in the feed. 22. The Fig. on the opposite page exhibits the parts of a surface condenser, and the manner of its operation. A A is the condenser; b is the exhaust pipe from the cylinder, and corresponds with m in p. 53; I is the injection, which corresponds with o in p. 53. Now if all the pipes and partitions seen in the condenser A A were removed, it would become like the condenser n p. 53, and the exhaust steam and condensing water would mingle as they do in p. 53. And when these tubes, etc., become leaky, as is sometimes the case, rip them out, and A A becomes no longer a surface condenser, but operates precisely in principle like that in p. 53. 23. The operation in A A, having all its tubes and partitions perfect, is thus. The exhaust steam h enters an. upper chamber?, thence passes and repasses, as the arrows show, through small tubes into a lower chamber J, where, its heat having been extracted by the condensing water showered upon and among the tubes from the injection I and strainer m, the steam has become condensed to water. This flow of steam through the pipes, and shower of water upon them, are both promoted by artificials means--the former by the fresh water air pump fy which draws through the fresh water channel e e / and the latter by the salt water air pump p, which draws through the channel n and foot valve o. The fresh water air pump forces the water of the condensed steam into the fresh water reservoir gf 66 THE STEAM EBTGXNE. whence it is drawn for feed; and the salt water air pump forces the condensing water into the salt water hot well q, whence it mostly...show more
