H. FLATTEM. FEED WATER HEATER AND PURIPIER. APPLICATION i'ILED OCT. 24, 1913.
1,098,030, Patented May 26, 1914,
HANS FLAT'IEM, OF MINNEAPOLIS, MINNESOTA.
FEED-WATER HEATER Am) PURIFIER.
Specification of Letters Patent.
Patented May 26, 1914.
Application filed October 24, 1913. Serial No. 797,060.
To all whom it may concern Be it known that I, Hans FLA'r'rnM, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Feed-lVater Heaters and Purifiers; and I do hereby 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.
My invention has for its object to provide an improved feed-water heater and purifier, and, to this end, it consists of the novel devices and combinations of devices hereinafter claim.
In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.
Referring to the drawings, Figure 1 is a side elevation of a steam boiler having incorporated therein my invention, some parts being broken away, and some of the exposed parts being sectioned; Fig. 2 is a detail view partly in rear elevation and partly in transverse vertical section, taken on the line 02 m of Fig. 1, on an enlarged scale; Fig. 3 is a longitudinal vertical section, taken on the line 02 m of Fig. 2; and Fig. 4 is a perspective view of the top tray, some parts being broken away, and some of the exposed parts being sectioned.
The numeral 1 indicates a horizontal steam boiler, and the numeral'2 indicates the fines thereof. A feed-water pipe 3 and a steam pipe 1 tap the boiler 1 at the top thereof. In the front of the boiler 1, above the water line Z, is .a normally closed manhole 5. The parts thus far described may be of the standard or any desired form.
Extending above and longitudinally with the flues 2 is a pair of parallel forwardly and downwardly inclined bars 6, the ends of which are bent laterally downward and anchored to the fines 2 by clips 7. These bars 6 aiford a rack for supporting a plurality of long shallow trays 8, having alternately inclined bottoms. As shown, the rack is arranged to give the proper pitch to the lowermost of said trays, and the side flanges of the other trays are beveled, in order to give the proper pitch to the intermediate and top trays. These trays rest directly one upon the other, and the one forms a described and defined in the cover for the other. A removable flat cover 9 is provided for the top tray 8. This tray is also provided, at its highest end, with a transversely extended, elongated distribut lng mouth 10, directly underlying the dellvery end of the feed pipe 8. The mouth 10 extends substantially the full width of the tray, and its upwardly and outwardly inclined bottom distributes the water re ceived from the feed pipe 3 over the full width of the bottom of the tray. At the delivery end of each tray 8 is an elongated discharge opening 11, which extends the full width of the tray.
The water delivered from the feed pipe 3 flows in a shallow stream over the bottoms of the several trays, and, from one tray to the other, it flows unobstructed through the discharge openings 11. The direction of the flow of water is reversed after passing through each tray, thereby securing a relatively long flow in comparatively short trays. Lime, or similar deposits that usually form a scale in boilers, is removed from the water during its flow through the several trays, and adheres to the bottoms of said trays. From the discharge opening 11, in the bottom tray, the water flows into a catch pan 12 supported directly thereunder on the fines 2. By reference to Fig. 3, it will be noted that this catch pan 12 is submerged slightly below the water line Z. All floating materials in the water will be deposited in the catch pan 12. A blow-off pipe 13 extends from the catch pan 12 through the back head of the boiler 1. In actual practice, the feed pipe 3 and blowoff pipe 13 will be equipped with suitable cut-off valves, not shown. In opening the valve in the pipe 18, for the purpose of blowing ofl the surface water in the boiler, all settlings deposited within the catch pan 13 will also be discharged through the blow-0E pipe 3.
To the bottom of the lowest trap S is secured a pair of angle bars 14, which embrace the bars 6, as best shown in Fig. 2, and thereby hold the said tray against lateral movement on the rack. These angle pieces 14: also afford a reinforcement for the bottom tray. All of the trays 8, with the exception of the bottom one, are provided with depending clips 15 arranged to embrace the sides of the underlying trays and thereby hold said trays against lateral sliding movement one upon the other.
The trays 8 and cover 9 are held assembled on the rack by means of a pair of yokes or straps 16, which extend completely therearound and under the bars 6. The intermediate portions of these yokes 16 are transversely divided, and the ends thereof bent laterally outward and secured together by rivets or bolts 17. It is important to note that the trays and cover are of a size which permits of their insertion or removal through the man-hole 5, when separated one from the other. This construction is important, in order that the trays may be removed from the boiler from time to time, in order that the scale formed thereon may be removed. Vhen it is desired to remove the trays from the boiler, the straps 16 are first removed from the trays by cutting or separating the bolts 17.
By actual usage of the device, it has been found that practically all of the lime, or similar deposits in the water, will adhere to the bottoms of the several trays, thereby greatly increasing the efiiciency of the boiler. By passing the water in thin sheets over the bottoms of the trays, the same is very quickly heated, and, by the time the water passes from the last tray, it is at substantially a steaming point. In placing the trays one upon the other, and covering the last tray with a removable cover, the Water in the trays will not be sucked through the steam pipe 4 which is located directly above the trays.
What I claim is:
The combination with a boiler, having a man-hole, of a rack secured to and projecting above the fines of said boiler, a plurality of open trays mounted on said rack and removably supported one upon the walls of the other and the one forming a tight cover for the other, the bottoms of said trays being alternately inclined and arranged to deliver one into the other, a removable cover for the uppermost of said trays, a feed pipe arranged to deliver into said upper tray, a submerged catch pan spaced below and arranged to receive from the lowermost of said trays, a blow-ofi' pipe leading from said catch pan, and anchoring straps for holding said trays and cover assembled on said rack, said trays and cover adapted to be independently removed or inserted through the man-hole in said boiler.
In testimony whereof I affix my signature in presence of two witnesses.
HANS F LATTEM.
