WILLIAM C. LANG, OF LIVERPOOL, ENGLAND.
Specification form'ing part of Letters Patent No. [80,601, dated August 1, 1876; application filed July 24, 1875.
To all whom 1' t may concern:
Be it known that I, WILLIAM CUNNINGHAM LANG, of Liverpool, in the county of Lancaster, England, have invented Improvements in, and applicable to, Steam-Boilers, of which the following is a specification:
My invention relates to that class of steamboilers in which the water is caused to circulate through the shell of the boiler from a lower to a higher level; and has for its object the prevention of leakage, corrosion, pitting, and deterioration of steam-boilers, (more especially marine boilers,) due to unequal expansion and contraction of the shell caused by the lower temperature of the water, which lies near the bottom of the boilers.
For the above purposes I cause the water to circulate from the lowest portion of the boiler through the shell, thence upward into the water-spaceat a high er level, preferablyat a point near the steam-space, or into the steam-space itself. To insure that the water shall be caused to circulate from the bottom of the boiler to a higher level-that is, to a position where there is a higher temperature-- I attach to the lowest portion of the boiler one or more water-boxes, and connect them,
by suitable pipes, with the boiler, so as to draw the comparatively cold water from the sides of the boxes, and deliver it into the upper part of the boiler; and inorder to prevent the-water in the boiler from descending and sediment-cock. Fig. 2 is a vertical section of a portion of a boiler and the waterbox, provided with the baffle-plate. Fig. 3 is a side view, partly in section and partly in elevation, of a double-ended boiler, having my improvements applied. Fig. 4 is an elevation of one end of the boiler, &c., shown in Fig. 3.
Like letters of reference indicate like parts in each.
a represents a boiler, which may be of any approved form, and is provided with a furnace, b. To the lowest part of the boiler I secure a water-box, c, which connects with the bottom of the boiler, either directly, as shown in Fig. 2, or, preferably, by means of a short pipe, 0, and with the upper part of the boiler (preferably at or near the steam-space) by a circulation-pipe, e. Passing through a gland on the water-box c is a rod, provided with a hand-wheel, by means of which a stopvalve, f, situated within the water box, may be operated to shut 01f the connection between the bottom of the boiler and water-box, when desired. I also provide the water-box with a cock, 9, through which any mud or sediment collecting in the box may be drawn off. When the connection between the waterbox and boiler is direct, it is desirable 'to break up the column of descending water, and for this purpose I interpose between the inlet and exit pipe a perforated plate or diaphragm, j, termed a baffle-plate. To insure the circulation of the water,.pans, pumps, or other, well-known mechanical appliances, may be interposed between the water-box and the upper part of the boilerthat is, in thelength of pipe 6; or heat may be made the medium for inducing and maintaining the circulationas, for instance, pipes passing alongside or through the fire-places. .For the purpose of completely illustrating the devices in connection with a marine boiler, I have elected to show hollow fire-bars, marked 0, such devices being deemed best adapted to the purpose. The circulation-pipes e are, by preference, caused to enter the boiler at a higher level than shown on the drawings, and when the circulation is caused by means of hollow firebars, check-valves may be placed in the circulation-pipes below such fire-box.
The operation of these devices is as follows: The cold water from the bottom of the boiler sinks into the water-box c, descends upon one side of the baffle-plate j, and passes through the perforations of the baffle-plate, which break up, equalize, and check the column of water, and on reaching the opposite side of the baffle-plate, enters the circulation-pipe 0',
passes or is drawn thence by any of the several suitable means enumerated, and is delivered into the upper part of the boiler. When it is desirable to interfere with the circulation taking place through the water-box, the valve f is forced in to cut off the connection between 1. In combination with a steam-boiler, the water-box c, communicating with the lowest portion of the boiler, and provided with the.
baffle-plate, the circulation-pipe, and suitable means for establishing and maintaining the circulation of the water in the boiler, substantially as specified.
2. In combination with a steam-boiler, the box 0. substantially as herein described, provided with the cock g, connected with the boiler by the circulation-pipes c e, the pipe 0 being controlled by the valve f arranged-within the box, substantially as and for the purpose specified.
