DEVICE FOR REMOVI NG SEDIMENT FROM STEAM-BOILERS.
SPECIFICATION forming part of Letters Patent No. 241,360, dated May 10, 1881.
Appli. ation filed July 6,1880.
To all whom it may concern:
Be it known that we, SAMUEL J. HAYES, EDWARD T. J EFFERY, and HENRY SOI-ILACKS. all residing at Chicago, in the county of (look and State of Illinois, and citizens of the United States, have invented new and useful Improvements in Devices for Removing Sediment from Steam-Boilers, of which the following is a full description, reference being bad to the accompanying drawings, in which- Figure i represents a longitudinal section, in elevation, through a boiler and furnace embodying our improvement. Fig. :3 is a transverse section of a boiler, showing a side elevation ofthe washing apparatus in position. Fi g. 3 is a plan view; Figs. 4 and 6, enlarged views of the device detached Fi g. 5, a longitudinal section of the wash-pipe; Fig. 7, a section through the crown-sheet of a furnace and between the crown-bars, showing spaces between the crown-bars and sheet, through which spaces jets of water are forced and distributed in the operation of the device.
By the generation of steam in boilers various impurities held by the water in suspension and in solutionare precipitated, and the sediment is deposited in varying quantities on the inner surfaces of the boiler-sheets, the lines, and braces. The deposits of sediment accumulate most rapidly about those portions of a boiler where the heat is strongest and steam freely generated. The crown or roof of the furnace in tubular boilers, by reason of its exposure to intense heat and its form, offers favorable conditions for the rapid formation of incrustations.
The difficulty of removin g incrustations from the crown is so great, in consequence of the numerous bars and braces supporting the sheet and limiting the room for the introduction and manipulation of the tools necessary for cutting away the deposits, that in many cases the attempt is not made, the sediment being allowed to accumulate until the spaces under and. between the crown-bars become obstructed to such an extent that the circulation of water over the furnace and the generation of steam are seriously impeded. It then becomes necessary to open the boiler, remove the crown-bars and braces, and cut away the scale with suit- (No model.)
able toolsan operation at once laborious and expensive. It is to this part of a boiler,and to the purpose of removing sediment there deposited, that our invention applies with esspecial advantage. These deposits do not become hard at once while covered with water, but harden gradually, and our improvement is adapted to remove them while soft.
The primary object of this invention is to remove the sediment deposited on the upper surface of the crown-sheet of a boiler to which the device may be applied without disturbing or removing any part of the boiler, the machinery attached, or the structure investing it, which we accomplish by the use of Water under suitable pressure, as hereinafter fully described.
A further object of the invention, and of which its mechanism admits the performance without alteration, is the partial purification of the wa ter in the boiler by ejecting from time to time a portion of the impure water through the apparatus, which then serves the purpose of a surface-cock.
1n the drawings,in which we have shown a locomotive boiler and furnace, A represents a pipe located within the boiler, in front of and extending across the furnace, which may be secured in position in any suitable manner. The inner end of the pipe is closed, and the side toward the furnace is perforated at intervals, and the apertures a are slightly above the crown, and through them water can be forced over the crown, through the spaces b, between the crown-bar bolts n, and under the bars H, as hereinafter described.
B represents a valve, which, when seated, prevents the escape of steam and water from the boiler, and when open affords a passage through the pipes connected therewith.
0 represents a metal sleeve passing through and securely fastened to the outside sheet of the boiler, affording suitable attachment for the pipe A and valve B. The inner end of the pipe is, as shown, held by a support, a.
D represents a lever attached to the valve B.
E is arod connected to the lever D, by which the valve may be operated.
F represents a pipe secured at one end to the valve B, and extending from the valve a sufficient distance to give room for the convenient l to into the pipe A, through the valve 13 and.
attachment, at its opposite end, of a hose for supplying water to the pipe A.
The operation of the device in its primary function is as follows: Connection having been made at F with a water-supply under suitable pressure, the valve B is to be opened, thus forming a continuous passage through the pipes F and A, and the water which escapes through the apertures a in the pipe A will be forced over the crown in strongjets, and will impinge on the surface of the sheet, and by its action will dislodge and remove any deposits of sediment which may have formed there. At the time of applying the Water it will be advisable to open the hand-holes in leg of boiler, to allow the sediment to pass off with the water from boiler.
This operation should be performed frequently, as often as the boilers are allowed to cool, and before cooling, or at such other times as circumstances may-require.
The device can be used as a surface-cock by raising the valve B by means of the rod E and connecting-lever D, Wl'llClljVlll permit the escape of the surface-Water charged with impurities, which, under the pressure of the steam in the boiler, will be forced through the apertures pipe F into the atmosphere, the quantity permitted to escape being regulated by the movement of the valve, as may-be desired. Ofcourse this operation is not performed when the pipe F is connected with the water-supply.
The WLIVB may be so arranged that the force of the water flowing under pressure through the tube F will open it.
What we claim as new, and desire to secure by Letters Patent, is as follows:
1. In a locomotive-boiler, the pipe A, having a series of perforations along the line of the crown-sheet, and in combination therewith and with operating mechanism, substantially as described.
2. The combination of the perforated pipe A, arranged across the boiler, with the valve B, lever I), and pipe F, as described, whereby the crown-sheet may be washed between it and the crown-bars, substantially as specified.
