Specification forming partnf Letters Patent No. 111,916, dated February 21, 1871; reissue No. 5,394, dated May 6, 1873; application filed March 28,1873.
To all whom it may concern:
I Be it known that we, Josnrn Drrlwon'rn and JQHN (JOBQURG HODGINS, formerly of Toronto, inthe county of York and Province of Ontario, Canada, but the said JOSEPH DIL- WORTH now residing in Muskoka District, Canada, aforesaid, have invented an Improved Condenser and FeedWater Heater for Steam- Engines ;v and that the following is a full, clear, and exact description. thereof, reference being had to the accompanying drawing making a part of this specification, in which- Figure 1 represents a vertical section through the apparatus, andFigs. 2and3representtransverse sections through the same at the linesm.
sists, first, in the construction and arrangement of a feed-water cylinder having in it a series of steam-pipes, which pass throughthe water space of said cylinder, and having the feed-water supply-pipeat the bottom of the cylinder, and the steam inlet pipe and the boiler supply-pipe at the top of said cylinder, for the purpose stated; and our inventionfurtherconsists in a perforated plate in the cham ber above the upper ends of the vertical tubes of the feed-water heating apparatus to prevent any foreign blow cocks or valves applied to and combined with the chamber above the perforated plate, and into which chamber the exhaust steam is admitted for the removal of any and all sediment therefrom.
To enable those skilled in the art to make and use our invention, we willproceed to do,-
scribe the same with reference to the-drawing.
The cylinder 0 is made of any suitable size substance from obstructing the tubes; and our invention further consists inand shape for receiving the ranges or series of vertical tubes 2) b that pass through the heads c d, and are secure therein. The tubes'b should be of small diameter, and many in number. We prefer to make these tubes of copper. The head 0 is made small enough to pass freely into the cylinder at, and the packing 6 makes a tight joint around this head whenin 1 place. The packing e is made of an Indiarubber ring introduced into a V-shaped or dovetailed groove around the interior of the cylinder a, and the head d is bolted upon the upper end of the cylinder a, and within the chamber f formed by an enlargement of the cylinder 41. The steam is admitted by a pipe, 9, into the chamber f and above the convex perforated plate It that serves to retain any foreign substance and prevents its passing into the tubes b and obstructing them.. Around the edges of the chamber j cocks or valves is are provided to allow for blowing 0% any sediment or accu- 'mulation. above the perforated plate h. The
feed'water is pumped or forced through the pipe I and check-valve m at the lower part of the cylinder a, but above the head c, and the heated water passes by the pipe at to the boiler. Cocks or valves are provided at 0 around the lower part of the feed-water space in the cylinder a so as to allow for blowing off any sod-- iment from the feed-water. A pipe, p, and a rose or sprinkler, s, are employed for introducing a spray of cold water into the chamber below the head 0 so as to condense the remaining portion of any steam that may pass down through the tubes b, and a pipe, r, leads to an air-pump by preference, or to a tank from which the feed-water is taken to the pump.
- By this construction the parts are easily kept free from sediment or foreign matter, leakage from expansion and contraction is prevented, the parts are not expensive to make or to keep in repair, a great saving of fuel is effected by the transferof the steam-heat to the feed-water; and in consequence of the cool feeding-water entering atthe lower part of the chamber containing the vertical range of tubes, and passin g up in contact with the steam-tubes through which the steam descends, the condensation of the steam is very perfect, and the feed-water is more and more highly heated as it passes up against the tubes wherein the steam is more and more highly charged with heat until the hi ghly-heated water comes in contact with the steam which has not as yet parted with any of its heat, and is then suddenly heated to the highest possible temperature, and in that condition passes from the upper part of the cylinder to the boiler.
It will beperceived, in the operation of this feed-water heater, that while the cold water enters at the lower end of the cylinder the hot steam enters at the top thereof and passes down through the tubes 1) to the lower end of the cylinder, and that by passing thewater and the steam in contrary directions the coolest water comes first in contact with the coolest steamthat is, ofthe lowest temperaturesand asthe water continues to rise it meets steam of higher and higher temperature, and thus gradually increases in temperature as it rises until at or near the top of the cylinder the highly-heated water comes in contact with steam that has not parted with any of its caoric, and it becomes suddenly and highly heat ad, in which condition it is taken through the pipe at to the boiler. the cylinder is not uniformly heated. It is quite cool at the bottom, and becomes more and more highly heated toward the top of the column, where, as above stated, it meets with The column of water inor has imparted to it thejthe temperature of the exhaust steam, and it there becomes highly heated, and this highly-heated portion is thence taken to the boiler.
Having thus fully described our invention, what we claim therein as new, and desire to secure by Letters Patent, is
1. In a feed-water heater, the combination of water-cylinder a, steam-pipes-b passing through the heads of said cylinder, steamchamber f above said steam-pipes, into which chamber the exhaust steam enters, condensing and'vacuum chamber below but connecting with said pipes for superinducing the downward passage of the steam-through said pipes, and preventing back pressure, water-inlet Lat the lower end water-exit n at the upper end of said cylinder, all arranged as and for the purpose described and represented.
2. The perforated plate It in the chamber f above the vertical ends-of the vertical tubes b of the feed-water heating apparatus, for "the purposes set forth.
3. The blow cocks or valves applied to and combined with the chamber f and perforated plate h, for the purposes set fort JOSEPH DILWORTH. JOHN OOBOURG HODGINS.
