. of which the following UNITED STATEs ATENT .FFICE DAVID P. STEWART, OF BUFFALO, NEW YORK.
FEED-WATER H EATER.
SPECIFICATION forming part of Letters Patent No. 232,563, dated September 21., I880. Application filed July 22, 1880. (No model.)
To all whom it may concern Be it known that I, DAVID P. STEWART, of the city of Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Feed-Water Heaters, is a specification, reference being had to the accompanying drawings.
The object of this invention is the construction of a simple and cheap apparatus, whereby the feed-water is brought into intimate contact with the exh aust-stearn and thoroughlyheated,
' and whereby the water is completely separated from the exhaust-steam mitted to escape.
My invention consists of the particular construction of the device,-whereby the exhauststeam is brought in contact with the feed-water and the combination of this device with before the latter is perthe casing of the heater, as will be hereinafter set forth.
In the accompanying drawings, Figure 1 is a sectional elevation of my improved feed-water heater. Fig. 2 is a cross-section on an enlarged scale in line as m, Fig. 1. Fig. 3 is a bottom-plan view, on an enlarged scale, of the device, whereby the feed-water and exhauststeamare brought in contact with each other.
Like letters of reference refer to like parts in the several figures.
A represents the case or shell of the heater,
7 which may be of cylindrical or other suitable form,
and be constructed of iron, wood, or other suitable material. As shown in the drawings, it is composed of a cylindrical shell, a, of sheet-iron, and an upper head, I), and lower head, 0, constructed of east-iron, and secured in the ends of the shell by rivets.
D is the exhaust-pipe which enters the upper part of the case A, preferably through the upper head,b, as shown, with its end opening downwardly.
E represents an enlarged extension of the exhaust-pipe, which is removably secured to the end of the latter within the casing A, either by a screw-thread, as shown, or by flanges and bolts. The end of the exhaust-pipe D is provided with an exterior screw-thread, which engages in an internal screw-thread formed in the opening in the head I), through which the pipe D passes and is furthermore secured by a jam-nut, f, applied to the threaded portion of the pipe on the upper side ofthe head b, while the extension E is secured to the threaded portion of the pipe D, below the head I), as clearly shown.
G represents the feed-water pipe, which enters the casin g Athrough its side and turns up ward within the casin g, and projects into the extension E of the exhaust-pipe, where it terminates in a conical spray-nozzle,H. The upright portion g of the feed-water pipe is secured with its lower end by means of a screw-thread in a bridge-piece, I, which is secured across the open lower end of the extension E by bolts j.- The extension E is enlarged where it surrounds the nozzle H and upright portion gof the feed water pipe, so that the flow of the exhauststeam through the extension E is not obstructed or retarded by these parts.
K represents a pipe leading from the upper part of the casing A to the open air, and through which the exhaust-steamywhich has not been condensed by contact with the feedwater, is permitted to escape.
L is the pipe, through which the heated feedwater passes from the lower part of the casin g A to the feed-pump.
M is the waste-pipe, secured in position'in the lower head, 0, its up per end with a valve, a, I and closed by a lever, N, carrying at the end of its long arm a float, O. The mouth of the waste-pipe M is arranged at a considerable distance below the open end of the extension E, so as to leave a large space between the latter and the water-level, in which the steam issuing from the extension E can expand and free itself completely from the finely-divided feed water, with which it is mixed. I
The feed-water is broken up in the nozzle H into a fine spray and brought into intimate contact with the exhaust-steam in the extension E, which forms a mingling-chamber, in which the caloric passes from the exhauststeam to the feed-water during the descent of the steam and water through the lower portion of the extension E. The mixture of steam and water issues from the latter in a downward direction, and all the Watery particles are thrown down into the lower part of the casing A by the combined action of gravity D. P.
