STEAM-GENERATOR.
SPECIFICATION forming part of Letters Patent No. 291,959, dated January 15` 184.
('No model.)
fo @ZZ wlw/n, t may concer/1,:
Be it known that I, THOMAs E. THOMPsON, a citizen of the United States, residing at Ohicago, in the county of Oook and State of Illinois, have invented certain new and useful Improvements in Steam-Generators; and I hereby declare the following to be a full, clear, and exact description of the same.
My invention relates to certain no vel combinations and arrangements of devices, wh ereby the steam-generating power of a boiler is enhanced and incrustation prevented by a circulation of the water through heated tubes and by passing the feed-water through pipes inside the boiler, so that the temperature may be raised to the same degree as that of the water in the boiler before it is discharged, when almost all the solids contained in water will be precipitated by gravity to the bottom of the mud-drum, and by means of partitions in the mud-drnm the sediment is prevented from being drawn by the circulation of the water into the water-tubes. I seek to accomplish these ends without any radical depart-ure from established principles and methods of boiler construction.
In the accompanying drawings, Figure l represents a Vertical longitudinal section of a furnace and tubular boiler provided with my improvements, certain portion of the boiler and other parts being broken away to show the internal construction; and Fig. 2, a vertical section taken through the lower muddrum and the adjacent end of the boiler.
A is a tubular boiler of ordinary form, mounted in a furnace, B. At the front and rear ends ofthe boiler are short and long standpipes O and C, connected to mud-drums D and D', having ilat sides facing each other. Into the ilat sides of these mud-drums are expanded the diagonal inclined water-tubes E, which extend across the furnace B, and which connect the water-spaces ofthe mud-drums D and D, and likewise the water-space of the front and rear ends of the boiler A. The muddrums D and D are suspended from the boiler A, and underneath each of them is placed a filling, e, of earth, sand, or other loose substance, in order to prevent the draft from pass ing around them, but so that they are free to vibrate when affected by expansion or contraction. The mud-drums D and D are provided with man-holes t t', t being in one muddrum and opposite certain of the interior water-tubes E, and the other man-hole, t', being in the muddrum D and opposite the remaining portion of the interior water-tubes E, so that in case of repairs, if it should become necessary to remove one of -the water-tubes E, the interior tubes can be removed through the manholes t t. The exterior tubes E can be drawn out outside ofthe mud-drums D and D. Opposite the manholes t and t are doors, so as to permit access to them. In the mud-drum D', I place the inclined pipes f ff, which form a continuation of the feed-water pipe R through the mud-drum, the object of these pipes being to pass the feed-water through them, causing it to be raised in temperature to as nearly as possible the same temperature as the water in the boiler before it is allowed to mingle with the latter, when the temperature will be'sufficient in most cases to precipitate all solids contained in water, which solids, being of a greater specific gravity than water, will settle to the bottom. The feed-water pipes form one coutinuous downward passage for the water and sediment to the end, and are formed in sections, so th at they can easily be removed to be cleansed of the scale that may forni in them. If desired, a pipe, f, may pass through the boiler and down the stand-pipe O.
In order that none of the sediment can be drawn up the water-tubes E, I put in partitions I I, and in order that we may be enabled at any time to get at the water-tubes E for any purpose, the partitions I) I should be put in in section, so that they can readily be removed.
At the rear of the grate-bars His the bridgewall I, below the tubes E, and still farther back is a second bridge-wall, I, mounted upon a T-beam, S, (or it may be arched over the tubes 13,) the bridge-wall I extending across the furnace and nearly to the bottom surface of the boiler, in order to deiiect most of the draft down upon the tubes E on its way to the firetubes E in the boiler A. As a result of the above construct-ion, as the steam is generated it ascends the inclined tubes E, and consequently forms a continuous motion and eircuit of the water through the water-tubes E, mud-drums D and D, stand-pipes O and O',
ICO
and boiler A. In connection with the foregoing I use a device for superheating and injecting steam for the purpose of accelerating 1combustion, a description of which is as foloWs: From the steamspace K a pipe, r, leads into the nre-chamber immediately under the arch lr', and is thence continued back and forth, as shown, and then passed down below the gratebars to a three-way cock, z', at the side of the ash-pit L, accessible through the ash-pit door q. From another opening in the three-Way cock a pipe, M, extends across the ash-pit from front to rear, and from this pipe extend nnmerons small pipes, p, perforated in their npper surfaces. From another opening in the three-Way cock a pipe, O, leads to the water- Space of the muddrum D, the openings in the three-way cock being such that when the handle is turned in one Way a connection is made between the superheating-pipes r and the perforated pipes p, and when the handle is turned another Way, so as to shut ofi' the connection between the pipes o and p, a connection is made between the Water-pipe O and the superheating-pipe fr, so that the pipe i' will fill with Water and bc prevented from burning out.
What I claim as new, and desire to secure by Letters Patent, is
l. In combination with the furnace B and 3o tubular boiler A, the stand-pipes C and C', muddrums D and D,Watertubes E, feed-water pipes B f f, and partitions PP', the Whole being constructed and arranged to operate substantially as described. 35
2. In combination with the tubular boiler A and furnace B, provided with the bridge-Walls I and I and doors u u', the stand-pipes VC and C', mud-drums D and D', having man-holes t t', and tubes E, the Whole being constructed 4o and arranged to operate substantially as described.
3. The combination of the tubular boiler A, furnace B, stand-pipes C and C', mud-'drums D and D', tubes E, pipes r, O, and M, three'- 45 way cock i', and perforated branch pipes p, the Whole being constructed and arranged to opcrate substantially as described.
