Description
E. L. MORSE. Peed-Water Heater.
Patented June INVENTORZL- V M H i I l1 UNITED STATES PATENT Orricn.
EDMUND L. MORSE, OF ST. LOUIS, MISSOURI.
FEED-WATER HEATER.
SPECIFICATION formingpart of Letters Patent No. 228,831, dated June 15, 1880. Application filed February 3, 1880.
To all whom it may concern Be it known that I, EDMUND L. MoRsE, of the city of St. Louis, in the State of Missouri, have invented certain Improvements in Heaters for Feed-Water for Steam-Boilers 5 and I do hereby declare that the following specification is a full, clear, and exact description of the" same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
This invention consists- First, in the arrangement of the heater in a horizontal position on one or more supportinglegs, which act as sediment-receivers, and are provided with suitable blow-off pipes and cocks for the removal of the same when required.
Second, in the combination, with a feedwater-heater, of a surface blow-off for removing the light impurities and scummy matter which rise to the top .of the feed-water. In this a hollow bushing is screwed in through the shell of the heater, and has a series of perforations at or below the inner line of the shell, through which the light impurities pass into the bushing and out through a suitable blow-off pipe and cook, by which the operation of the device is controlled and regulated.
Third, to certain details of construction, as will hereinafter more fully appear.
In the drawings, Figure l is a front elevation, partly in section, of myimproved heater. Fig. 2 is an enlarged detail section of the surface blow-ofi device. Figs. 3 and 4 are detail sections of the opposite ends of the heater.
As shown in the drawings, A represents the fced-water-inlet pipe; B, the feed-wateroutlet pipe; 0, the sediment blow-off pipes; D, the surface blow-0ft pipes; E, the drain or discharge pipe, and F a thermometer or gage for indicating the temperature of the feedwater in the heater.
The heater is arranged in ahorizontal position, and has the usual boiler-iron shell G, which is riveted at one end to an annular ring, H, attached by stud-bolts h to the head G. At the other end the shell is riveted to the cupshaped diaphragm H, which is attached to the head G h is a large central tie-bolt to assist in holding the heads G G together. This construction allows of the parts being readily taken apart for repairs when required.
H is a diaphragm, arranged between the 1 head G and the diaphragm H, to form two chambers, I I.
The heating-surface of the heater is formed of two series of pipe, one arranged inside the other. The external series of pipes, J, screw into the diaphragm H, and communicate with the chamber I, while the internal series of pipes, J, screw. into the diaphragm H and communicate with the chamber I. The opposite ends of the pipes have no fixed attachment, but are left free to expand and contract in the feed-water chamber, the free ends of the external series of pipes being closed by screw-caps J or other suitable device.
In use the exhaust-steam enters the chamber I and passes through the smaller series of pipes J forward to the ends of the same, and returns through the external series of tubes, J, and discharges into the water-of-condensation chamber I, which chamber, when the heater is used as an open heater, will be provided with an escape-pipe in addition to thedrainpipe E but when used as pressureheater the said escape-pipe is dispensed with.
L L are hollow supporting-legs, the interior of which communicate with the interior of the heater, and act as mud and sediment receivers for the same. They are provided with blowotf pipes O and cocks 0, through which they are blown off when required.
M are surface blow-offs, consisting of a cupshaped bushing, which projects down through the shell of the heater, and is provided with a number of openings around its sides on or below the inner line of the heater-shell, as clearly indicated in detail, Fig. 2. This bushing may either screw into the shell or be secured thereto by rivets or bolts, as desired. These blow-off bushings are provided with blow-off pipes and cooks D D, by which their action is controlled and regulated. As shown in the drawings, these blow-offs, having their receiving-openings close to the shell of the heater, will very thoroughly and effectively remove the light impurities and scummy matter that rise to the top of the feed-water.
N is a wooden jacket surrounding the heater, to form a non-conducting air-space around the same. Its ends are held down by annular projecting lips a on each head of the heater,
and its center is held together by one or more hoops 0r bands, at, as shown. n are lagging or distance pieces for holding the jacket in proper relative position to the heater-shell.
Having thus fully described my invention, what I claim is 1. The combination, with a feed-water heater, of the hollow supporting-legs L L, and blow-off pipes and Valve 0 O, as and for the purpose set forth.
2. The combination, in a feed-water heater, of the heating-tubes J J, diaphraglns H H, and shell G, havin a removable head, G G ateaoh end, as and for the purpose set forth.
3. The combination, in a feed-water heater, 15 ot' the shell G, riveted to an annular ring, H, to which the head G is secured by studbolts h, as and for the purpose set forth.
4. The combination, with afeed'water heater, of the cup-shaped surface blow-01f M, having 20 a series of holes on or below the inner line of the shell, as and for the purpose set forth.
EDMUND L. MORSE.
