VILIJIAM IIOUGHTALING, OF BRIDGEIORT, CONNECTICUT, ASSIGNOR TO EDWARD S. T. KENNEDY, OF NEW YORK, N. Y.
PERFORATED PLATE FOR DRYING STEAM.
SPECIFICATION forming part of Letters Patent No. 389,078, dated September 4, 1888.
Application filed June 1G, 1858. Serial No. 277,290. (No model.)
.To @ZZ whom it may con-cern.'
Be it known that I, WILLIAM HOUGHTYAL- ING, a. citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Perforated Plates for Drying Steam; and I do hereby declare the following to be a full7 clear, and exact description of the invention, such as will enable others skilled in the art to which it ap pertains to make and use the same.
This invention relates to the dryingtubes of steainboilcrs, and more particularly to perforated plates applied to the d ryingpipes and steam-tubes of radial-tube (porcupine) steam -boilcrs for facilitating the drying of steam within the boiler and preventing any tendency to priming.
The object of the invention is to provide for. supporting the steanrdrying pipes centrally in the radial steanrtubes of the boiler; also, to provide increased steaming capacityin aboiler of given size, by enabling the operator to raise the water-line, and thus utilizing a greater number of radial tubes-the lower steamtubes-for water, thereby protecting such tubes from overheat-ing, due to overfiring; and a further object is to produce drier steam than heretofore, and to prevent any tendency in this class of boiler to prime, which might result from overworking and abuse.
In carrying out my invention I apply perforated plates, each having suitable support` ing-lugs and a boss, to the mouths of the steamtubes, and particularly to those stealntubes into which extend the steam-drying pipes, in which case the perforated plates are slipped over the drying-pipes, and by their inwardlyextending lugs are thrust into the mouths of the radial steam-tubes, all as more fully described with reference to the accompanying drawings, in which- Figure l represents a vert-ical section of the upper portion of a radialtube steam-boiler with the furnace-shell removed, and showing the perforated plates applied to the upper stean1-tubes. Fig. 2 represents an inner face View of a perforated plate on enlarged scale. Fig. 3 represents a vertical section through the saine.
The stand pipe A is provided with the closely-set radial steam and water tubes a a', in the usual manner, and the usual steam-discharge pipe, B, extending With a closed lower end down into the stand-pipe, is provided with the steam-drying pipes l), extending with open onterendsinto thelargersteam tubes,a. These drying-pipes b are preferably made in two parts, united bya coupling for conveniencein connecting and removing them from the boiler. The perforated plates or disks C are usually applied by slipping them over the drying pipes b and securing them thereto by a setscrew in such position that they will cover the mouths of the steam-tubes a. The plates or disks C have cast upon their inner faces, a short distance from their peripheral edges, three lugs, f, having straight outer edges in proper position to lit snugly inside of the stean1-tubes a. Adouble row of perforations, e, is formed in the disks, and they are preferably made flaring from the outer to the inner face of the disk. A central boss or collar, d, is cast upon the outer face of the disk, and has an opening, e, extending through it and the disk for receiving the steam-pipe b. A setscrew, h, is applied to a screwthreaded hole in the boss for securing the disk to pipe b.
The perforated disks having the large central opening in the boss closed may be applied f to the mouths of steamtubes a below those which contain the drying-pipes, so as to spray any water which may be thrown up into such tubes; but I have found the perforated disks most useful and advantageous when applied to the steam-tubes containing the dryingpipes.
Then inserting the drying-pipes b in the radial steam-tubes o, the perforated disks are slipped over such pipes, and are then applied to the mouths of tubes a so that their lugs f fit snugly inside thereof, and the set-screw is then turned to hold the disk in place. In this position the disks hold pipes b exactly in the center of tubes a, and thus cause a better dow of steam. Pipe b, by being held at its open end off from the bottom of tube a, would not readily receive any water which might be thrown into tube a, while if the pipe sagged any water in the tube would enter the pipe and be blown bythe steam through it into IOO Y city of the boiler.
a 'seams steam-outlet pipe B. The perforated plates also serve to a great extent to prevent water from entering the tubes a, to which they are appl-ied, since water thrown against the plates is broken into spray, and to a limited extent might enter the tube in that form, where it would be quickly converted into dry steam. The perforated plates, however, act to permit the passage of steam to the exclusion of water, so that steam only is passed off in a very dry condition. On account of the efficient action of the perforated plates the water-line can be raised in the boiler from six to twelve inches above that ordinarily carried and still make dry steam, thus increasing the steaming capa- Independent of the consideration of raising the Waterline, however, improved results are secured.
The area of all the openings in all the perforated plates in any-sized boiler is varied with the requirements of the case, and may be more or less than the area of the steam-pipe leading from the boiler.
Having described my invention, what I claim, and desire to secure by Letters Patent, 1s
l. In a radial-tube steam-boiler, the combination, with a steam-drying tube extending into the re-box, of a removable perforated plate applied to the tube for spraying any water which may be thrown against the mouth of the tube, and thereby producing dry steam.
2. In combination with the steam-tube of a boiler and its internal drying-pipe, a perforated plate applied to the mouth of the tube and supporting centrally the internal pipe, for the purpese described.
3. In combination with the steam tube of a boiler, a perforated plate provided with inwardly-projecting lugs for supporting it in the mouth of the tube, as described.
4. In combination with a steam-tube and its internal pipe, a perforated plate having inwardly-projecting lugs to support it in the tube and a large central opening for the passage ofthe internal pipe, as described.
5. In combination with asteam-tube and its internal pipe, a perforated plate having inwardly-projecting lugs, a boss or collar provided with a large opening, and means for securing the collar to the internal pipe, all for the purpose described.
In testimony whereof I affix my signature in presence of two witnesses.
