PHILIP J. KEENE, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO GEORGE J. ROCIUVELL, OF SAME PLACE.
BOILER.
SPECIFICATION forming part of Letters Patent No. 61 84, dated Febr ary 1399- Application filed April 7,1898.
To all whom it may concern.-
Be it known that I, PHILIP J. KEENE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Boilers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.
My invention relates to steam-boilers of the water-tube type 3 and my object is to produce a more compact, effective, economical, simple, and accessible boiler than those heretofore produced.
To this end my invention consists in an incased boiler composed principally of an upper and lower water-drum connected by a set of peculiarly constructed and arranged watertubes, in connection with a feed-water heater and other accessions and peculiarities, all of which will be more fully described hereinafter and pointed out in the claims. I
In the accompanying drawings, Figure 1 represents a vertical sectional view of my complete apparatus; Fig. 2, a horizontal section through at w of Fig. 1, showing the arrangement of the water-tubes and fire-tubes in the upper water-drum; Fig. 3, a horizontal section through y y of the lower portion of the upper water-drum, showing the location and relative arrangement of the water-tubes of the boiler and water-tubes of the heaterin the upper tube-sheet; Fig. 4, ahorizontal section throughz z of the boiler, showing the grouping of the water-tubes at the lower waterdrum; Fig. 5, a detail sectional view through the flanges which connect the removable top of the upper water-drum of the apparatus; Fig. 6, a horizontal section showing the arrangement of the blow-off pipes which are connected with a ci reular mud-drum, and Fig. 7 a horizontal section showing the arrangement of the exterior annular feed water header with the inturned water-pipes.
The numeral 1 denotes the lower waterdrum,located directly above a furnace 2. This drum consists of a vertical cylinder having a $erial No- 676,79Z. (N0 model.)
central frusto-conical opening 3, which forms part of the combustion-chamber 14. A manhole 4 is provided in one side of the drum and extends horizontally through a surrounding brick casement 5. V The inner plate 6 of the lower drum 1 diverges downward and is united at the bottom with the outer sheet 7 to form the frusto-conical opening 3 of the combustion-chamber 14, through which the products of combustion pass upward among the water and fire tubes. The top of the drum is covered by a horizontal flue-sheet S. The upper water-dru1n 9 is also cylindrical and is connected with the lower drum by a plurality of vertical straight water-tubes 10, attached, respectively, to the top and bottom flue-sheets 8 and 11 of the two drums. An annular series of circulating water-tubes 12 extend from the inside sheet 1 of the drum 1 into the central opening 3, whence they are curved or bent upward, then slightly'inclined outward until they enter the flue-sheet 11, forming the bottom of the upper water-drum 9. The bent or curved portions of these circulating-fines lie directly in the path of the heat, which impinges upon them, thereby intensely heating and driving the water within them rapidly upward, while the outer row of straight tubes 10, which are necessarily much cooler, will draw the water down into the lower drum, from which it is again sent upward through the circulating-tubes 12. This arrangement produces a healthy circulation in the boiler and prevents incrustation.
The upper water-drum 9 contains a large central flue 12. This flue is directly above and coincident with the combustion-chamber 14 in the drum 1 below. The top 13 of the upper water-drum is made removable in the manner which will presently be described.
The central flue 12 is in direct open communication with the main combustion-chamber 14 below, and is provided with acircular castmetal damper 15. This damper is convex on the under side, with an annular flange 15 around its rim, encompassing the extended top of the flue, and is raised and lowered through the medium of a lever 16, link 17, and eyebolt 18. The lever 16 passes out through the metal hood 19 on the easement 5, on which it is fulcrumed, and its outer end is provided with a depending chain 20. Ex cessive heat within the generator can be reduced by raising the damper 15 and allowing the products of combustion to pass up directly through the central flue 12 and out of the smoke-stack 21. It will be seen that the central flue 12 and damper 15 serve as a large manhole device, by which easy-access can be had to the upper water-drumby merely removing the damper.
Horizontal radial fire-tubes 22 are placed in the upper water-drum with their opposite ends passing through the sides of the drum and flue, respectively. Several layers of these fire-tubes 22 in the drum 9 are above the water-line. These uncovered tubes will superheat and dry the steam rising from the water in the steam-dome. A group of inclined water-circulating tubes 23 is placed across the lower part of the flue 12' to increase the circulation of water. A manhole 24 is located in the side of the drum opposite these circulating-tubes, whereby the tubes and interior of the drum are made accessible for repairs. The separable top or section 13 of the upper water-drum 9 is of the same diameter as that of the drum and constitutes a prolongation of the latter. This top is tightly secured by a peculiar kind of flange-joint 25, consisting principally of four cast rings 26 27 and 28 29. The outer or larger rings 26 and 27 connect and seal the contiguous edges of the top 13 and drum 9, and the smaller rings 28 and 29 encircle, connect, and seal the contiguous edges of the flue 30. Each ring is L-shaped 'in cross-section to provide laterally-projecting flanges 31, which are fastened together by vertical bolts 32. The peripheries of the rings are attached to the contiguous edges of the top and drum, respectively, by rivets 33. The adjoining sides of the rings are provided with an annular tongue-and-groove joint 34, capable of receiving packing to make a steamtight joint between the two rings. By these means the top 13 may be readily separable from the drum to permit the latter to be opened wide for the easy removal or repair of any of the parts within, thus saving much time, labor, and expense of maintenance.
13to gain access to the bolts 32. Over the manhole there is a door 36 in the metal hood;
19 above.
The feed-water device shownin Fig. 7 consists of an annular header 37, which encircles; the casement or boiler-setting 5 at a point just above the top of the lower drum. Water is supplied to this header through pipe 38.
Equidistant radial water-pipes 39 proceed from the header 37 inward through the case-j ment 5 into the combustion-chamber 14,;-
whence they curve upward between the. groups of vertical water-tubes, terminating at the bottom flue-sheet 11 of the upper wa-- An ad ditional manhole 35 is provided in the top water pipes 39, in order to insure an abundant supply, and the number comprising the latter will be equal to the number of spaces between the groups of water-tubes connecting the lower and the upper water-drums.
A mud-drum 40 encircles the lower part of the furnace and lies below the floor. Mud is discharged from the bottom of the lower drum 1 downward into the mud-drum by means of the radial blow-ofi pipes 41. The casement around the furnace is composed of commonbrick, and above the top of the lower drum it may be linedwith fire-brick. It is optional whether the casement around boiler be covered with a sheet-iron jacket or not. This brick casement is capped by a ring 45, forming a base for the hood 19 to rest upon. The smoke-pipe 21 contains a damper 19. An upper deflector 46 encircles the outside of the upper water-drum and closes the hot-air space between the drum and the surrounding casement, thereby compelling the gases to escape through the fire-tubes 22 by way of the central 'tube 12. A vertical water-column extends from the header 37 of the heater up to a water-gage 47. Horizontal pipes in connection with the water-gage extend into the upper water-drum at points above and below the water-line 48.
