FEED-WATER HEATER AND PURIFIER.
SPECIFICATION formingpart of Letters Patent No. 252,147, dated January 10, 1882.
' Application filed April 23, 1881. (No model.) I
To all whom it may concern:
Be it known that I, CHARLES H. SHiELDs, of- Maywood, in the county of Cook and State of Illinois, have invented a new and Improved Feed-Water Heater and Purifier for Steam-Boilers, of which the following is a full, clear, and exact description.
The object of this invention is to prevent the deposit of sediment and scale in boilers.
The invention consists of a drum into which the feed-water is forced by pump or injector, which drum is eonnectedwith one end of the boiler by a check-valved pipe, through which steam and water pass from boiler to drum to heat the feed-water and cause a deposit of the sediment in the drum, and is connected with the other end of the boiler by a valved pipe, through which the heated feed-water from the drum enters the boiler. Y
The drawing represents a boiler and itssctting, with parts broken away to ezihibit the other parts, with my improved heater and purifier, partly in section, attached thereto.
In the drawing, A represents the boiler, B the boilerfront, and O the brick boiler-setting. D represents the heater and purifier, consisting preferably of a boiler-iron cylindrical drum about twelve inches in diameter and three feet long, its dimensions depending upon the size of the boiler to which it is applied, fixed about midway of the length of the boiler A in the brick work or setting 0. Said drum D is connected with the rear" end of the boiler A by a pipe, E, an inch and a halt'in diameter, or thereabout, which has oneend tapped into the side of said boiler A on the side thereof, at about the height of the upper tier of boiler tubes or lines, said pipe then extending upward on the outside of the boiler A, and then parallel with it to the drum D, into which it is entered, and then bent downward at right angles, as shown at a, for a third or more of the length of said drum D. Said pipe E is provided with a valve, 11, to regulate the flow of water and steam through it from the boiler A to the drum D, and with a check-valve, c, to prevent the return of water through said pipe E from the drum D to the boiler A. From the top of said drum D a pipe, F, extends to the front of the boiler A, said pipe F being preferably about an inch and ahalf in diameter, and, making a downward turn, is entered into the front of said boilerA at about midway between its sides, as shown. Said pipe F is also provided with a valve, d, to regulate the flow of feedwater through it.
I 'In the side of the drum D is apipe, G, provided with a regulating-valve, g, that is designed to be connected with a feed-water pump or injector, and at the bottom of said drum D is a blow'oft pipe, H, provided with a blow-off cook, it, whereby the sediment collecting in the drum D from the feed-water is ejected therefrom.
On the boiler A being fired and the engine Gr, heats the incoming water, which hot feedwater is then forced, by the combined pressore. from the pump or injector (not shown) and of the water and steam from the boiler, through the pipe E into the front of said boilerA, and, the teed-water enterin g the boiler 7 5 V A thns' heated, the boiler A suffers no check in making steam, as is commonly the case with boilers not provided with the best feedwater heaters; The heating of the feed-water in the drum D causes the sediment to deposit from the water in the bottom of the said drum D, whence it may be blown out on the opening of the blow-off cock h, and the steam and water from the boiler A coming in contact at an angle with the feed-water in the drum D creates counter currents or eddies therein, which create or maintain a comparative calm or still water below the mouth of the feeda pipe G, which materially assists'in the ready precipitation of sediment from the heated feed- 0 water.
it will be seen that by'this device a constant forced water-circulation of hot water is maintained through the boiler and heater D,
and,the feed-water being heated in the heater 5 or drum D and the sediment being thereby pre' cipitated therefrom, that little or'no deposit of scale or sediment can be formed in the boiler.
Haring thus described n1 yinvention, I claim as new and desire to secure by Letters Patent-' In a feed-water heater, the combination, with the boiler A and drum D, of the pipe E, con- 5 meeting said parts and extending downward into said drum with a rectangular bend, a, the feed-water pipe G entering said drum and having its innerend arranged near the end of pipe E and at right angles thereto, and the pipe F connecting the top of said drum with 10 the boiler, substantially as shown and described, the said drum being provided with a suitable blow-off pipe, as set forth.
