SPECIFICATION forming partei' Letters Iatent No. 413,914, dated October 29, 1889.
Application led April 171, 1889.` Serial No. 306,803. (No model.) v
.To all whom t may concern: Be it known that I, VIRGIL W. BLANCHARD, of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Tater-Heaters; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawings, and tothe letters of reference marked thereon, which form part of this specification, in whichp Figure l represents a perspective viewof my improved water heater and purifier, the casing being broken away to show the heating-coils. Fig. 2 is a reducedsectional view of the same, showing the heating-coils. Fig. 3 is a detail sectional view of the heatingcoil; Fig. 4, a detail view of a steam-pipe. Fig. 5 is a central vertical section through the apparatus complete, and Fig. 6 shows a modified arrangement of the coil` and steampipe.
This invention relates to improvements in apparatus which are designed for use in connection with a steam-boiler and a steam-engine, the object of which is to heat the feedwater onits way to the boiler-by the exhauststeam from the engine cylinder, and also to supplypure water to the boiler; and it consists in combining in a single case or shell a waterheater and a puriiier in the manner hereinafter clearly explained.
Further objects of the invention are to improve the construction of the heating-coil so that a large amount of heating-surface is presented tothe feed-water, and the combination and arrangement of parts.
Referring by letter to the drawings, A designates a casing made, preferably, of boileriron and of any desired capacity, and which is preferably of rectangular shape.
B B designate the inlet and outlet ports of said casing at top and bottom thereof, which are designed for connection, respectively, to the exhaust-pipe of an engine and to a condenser. In the lower part of the casing is a series or bank of pipe-coils C, arranged in close relation to each other in gangs. One
end of the continuous coil leads froma steamboi1er and the other end is preferably connected with the condenser (not shown inthe drawings) with which the casing A is connected, so that the water of condensation may be'drawn through the coil into the boiler. ,This coil is constructed as'hereinafter explained. At the lower end of the casing A isA a pipe provided with a cock 7c for drawing oif water of condensation from time to time as it accumulates.
D designates a steam-purifier, which is lo. cated near the top of the casing A and suitably supported therein. The shell of this purifier, like the shell of the casing, is made strong l enough Vto withstand high steampressure, and inside of it are a number of Siphon-legs E, the longest legs of which communicate with the chamber of the casing at the bottom of the purifier in which the coil is located, and the shortest legs of these siphons dip down below the water-line in the purifier.
For the purpose of causing a thorough diffusion of the steam issuing from the shortest legs of the said siphons I preferably employ a horizontal reticulated plate or wire-gauze diaphragm F, arrangedlhorizontally in the generator D at or below the water-line therein.
I designates a feed-water pipe leading from a convenient source and communicating with the upper part of the casing G', and also with the lower part thereof. These branch pipes H H are connected together outside the casing A by means of a gage-glass h, atthe lower end of which is a cock g, for drawing off the sediment which subsides to the bottom of casing I).
The straight portions of the pipe-coils C are secured by elbows c bysteam-tight joints, and all of the coils form one continuous channel, leading from a steam-boiler through the casing A. Between the tiers of pipe-coils C are arranged horizontal plates or diaphragms ES, as shown in Figs. l and 2, alternating, so that the exhaust-steam entering the bottom of the casing through inlet Bis compelled to take a serpentine ascending course through the casing, insuring a very thorough distribu` tion of the heated steam.
For the purpose of greatly increasing the heating capacity of the apparatus and to utilize the heat of the exhaust-steam to the IOO utmost degree I employ inside of the pipecoils C smaller pipes Dwhich may extend entirely through the coils C, opening at both ends b b in the steam-space of the casing, as indicated in Figs. 4 and 6, so that steam can freely pass through them as well as around the ceils. If desired, the steam-pipes D may be open at one end and closed at the other end inside pipes C by plugs d, as indicated in Fig. 3.
For the purpose of effectually sealing the joints of the inside or steam pipes D3 at the points b3, I employ tubular tapered plugs, (shown clearly in Fig. 6,) which plugs are screwed onto the ends of pipes D3 and into the openings in the Walls of the couplings c; or the plugs may be placed inside pipes D, as indicated in Fig. 4, and expand said pipes at their joints in the coupling. The pipes D3 are made of such diameter relatively to the bores of pipes C that the Water caused to circulate through the latter is reduced to a thin film, thus obtaining the greatest heating ef- 'fects in the smallest possible space.
Exhaust-steam from the engine-cylinder is alternately injected into the casing A and heats the water circulating through the pipecoil C, as described. The steam then passes through the siphons E in the purifier and is injected into the watertherein. whichis more or less impure. The water is thus in a measuredistilled and the impurities are precipitated, the steam passing off to the condenser laden with water and in condition for ready condensation.
By means of the glass gage h the height of the water in the generator or purifier D can be observed at all lrimes, and when necessary this purifier can be replenished by opening a cock 1l in the supply-pipe I.
From the foregoing it is clear that I utilize the heat of the exhaust-steam from an engine to heat the Water circulating to the boiler, and also to distill impure feed-water and sup ply purified water to the boiler, which is heated to a high temperature in the coil C, as is evident, previous to its delivery to the boiler.
Having thus described my in vention, what I claim isl. In an apparatus for purifying water for steam-boilers, the combination of a purifier provided with feed and outlet pipes and siphons with a casing provided with steam-inlet pipes, substantially as described.
2. In Aan apparatus for purifying water, the combination of a purifier provided with siphons and a reticulated diaphragm, and also with a feed-pipe, a steam-outlet pipe, and a sediment-cock, substantially as described.
3. In an apparatus for heating and evaporating water for steam-boilers'and other purposes, the combination, with a series of communicating pipe-coils arranged in a suitable casing, of steam-pipes open at one or 'both ends and applied longitudinally and centrally inside of the straight portions of the said coils and in communication with the steam-space of said casing at the bends of the coils, substantially in the manner and for the purposes described.
4t. A gang or bank of Water-circulating coils arranged inside a casin g, in combination with steam-pipes inside said coils and a series of alternate diaphragms arranged between the pipe-coils, substantially as described.
5. A gang or bank of water-circulating coils arranged inside of a steam-casing, in combination with steam-pipes inside the straight portions of the said coils, plugged at one end and communicating with the steam-space at the other end, substantially as and for the purpose specified.
(j. The colnbination of the casing provided with steam inlet and outlet pipes, a bank of water circulating coils, a series of short straight steam-pipes in said coils, and tubular conical plugs holding said steam-pipes in their places, substantially as described.
7. The combination of a casing having steam-inlet pipes and a coil of pipes communicating with a steam-boiler, in combination with a purifier consisting of siphons arranged in a case and communicating with the interior of the said casing, and the feed and steamoutlet pipes, all constructed and arranged to operate substantially in the manner and for the purpose specified.
8. The combination of a casing provided with steam inlet and outlet pipes, a bank of water-circulating coils of pipe, steam-pipes through the horizontal portions of said coils, and a series of alternating diaph-ra-gms between the coils forming serpentine channels for the circulation of steam through the cas'- ing', substantially as and for the purpose described.
9. In a Water heater and purifier, the combination of the casing, a vessel secured therein having a case provided with siphons, and water feed and drain pipes, with a coil of Watercirculating pipes below said vessel and a series of steam-pipes arranged inside the horizontallimbs of said coils, all'substantially as and for the purpose specified.
In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
