WILLIAM E. MOORE, 'OF PERUQILLINOIS HARRIET L. MOORE EXEGUTRIX OF SAID WILLIAM E. MOORE, DECEASED.

REQENERATOR-FU NACE.

- To all whom it may concern Beit known that I, WILLIA E. MOORE, a citizen of the United States, residing at Peru, in the county of La Salle and State of Illinois, have invented certain new and useful Improvements in RegeneratorFurnaces, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to an improved form of regenerator furnace in which several regenerators are disposed side by side .to supply heated gas and air to the furnaces associated with the regeneratorsto' heat the furnaces, the products of combustion from the.

furnaces being conducted through certain of the regencrators at the same time to heat them and thus store a large amount of the heat contained in the products of combustion for the purpose of subsequently heating the gas and air delivered to the furnaces. By my invention means are provided for using certain of the regenerators at one time for heating the gas and air, at which time the'other regenerators are used 'tostore the heat of the products of combustion as the exhaust gases pass on their Way to the stack;

and devices are employed for reversing these vcondltions as desired, so that the regenera- -t-ors first used to heat the gas and air may ppening' *into the furnaces so' that the burn mg gases may take the shortest possible path from the inlet openings, to the. outlet open.-'

ings that'will prop'erly'heahth contents of the-furnaces, as agrsult of which the burn ing gases are most effectively employed in lieating'the furnaces. Furthermore, by my inventmnfI dispose thepassages'. for the gases in such a 'riianner between two adjacent furnaces thatthe air and gas supplied to the furnaces are divided between the two adjacentffurnaces and the products of coinbustion are receiyed from the "two furnaces by comnlon'pass'ifges 'in'the'otherwise solid partition wallsepa-rating c eamer) adjacent furnaces. 4 These passages in th'efpart'ition' Specification of Letters Patent.

Application filed January 26, 1914. Serial No. 814.283.

The present invention is zinimprovement upon the construction of f'uvnace shown and described in United .States Letters Patent N 0. 750,868, issued Februa 2, 1904, to Philip A. MacKay and myself? The several drawingsillustrating my invention are as follows:

F1gure 1 shows in vertical transverse sectional'view, two adjacent furnaces and the associated regenerators in accordance with my invention, this section. being taken along the line 11 inFig. 2. Fig. 2 is a longitudinal sectional view of one of the furnaces and regenerators taken along the line 2-42- in Fig. 1. Fig. 3 is aplan'view of the stack for receiving the exhaust gases from the regenerators, together with the valve mechanism' for controlling the flow of air and gas to the regenerators and the flow of the eX- haust gases from the regenerators to the stack. Fig. 4 is a sectional view of the parts shown in Fig. 3 taken along the line 4- 4.

Similar numerals refer to similar parts throughoutthe several views.

As shown in Figs. 1 and 2, my furnace and regenerator construction consists in a plurality of longitudinal chambers 1, 2, 3 and 4- located in the base of the structure, said regenerators being filled with brick checker-work, as is usual in the construction of these devices. These regenerators 'have extending underneath them passageways 5, 6, 7 and 8 for supplying air and gasto the. regenerators or conducting fromthem the products of combustion, as the case may be. Above the regenerators two furnaces 9 and 10 are disposed which are similarly constructed, except that they are the reverse of each other, and furnaces are separated by a central partition walll l. This partition wall 11 has form'ediin it a plurality of series of communilzati-ng" 'p'assagelways connecting the furnaces 9 and 10 with the regenerators 1,2,3, and 4. As each series of passageways is identical with each other seriesjblrt one willbedescribed, it derstood'that one series f' after another-idem ployed throughout the entire length of the furnaces which are of substantially. the same extent longitudinally as the regenerators under them. The regenerator 1 is connected by the passageway 12'with the upper portion of'each of the furnaces 9 and 10, the upper end of this passageway being shown at 12 in Fig. 2; the regenerator 2 is connected by a passageway 13 with the upper portion of each of the furnaces 9 and. 10, the upper end of this passageway 'being indicated in Fig. 2 at 13*; the regenerator 3 is connected by the passageway 14 with the lower portion of each of the furnaces 9 and 10, the upper end of this passageway .being indicated in Fig. 2 at 14*, and the regenerator 4 is connected with the lower portion of each of the furnaces 9 and 10 by the passageway 15, the upper end of this passageway being indicated in Fig. 2 at 15. It will be understood that the passageways opening into each of the furnaces 9 and 10 follow each other in the same sequence in each series, and that the first passageway of each series communicates with the regenerator 3, the second of each series communicates'with the regenerator 4, the third of each series communicates with the regen- Merator 2, and the fourth of each series communicates with the regenerator 1. It will be further ob served that all of the passage ways communicating with the regenerators 3 and 4 terminate in.the lower portion of each furnace,- whereas the-passageways ex--"' tending from the regenerators 1 and 2 terminate in the upper portion of the furnaces. Itwill further be observed that the passageways extending upward through the partitions 11 are as close together as they can .be placed in view of. the'construction of the furnaces and that, therefo're, the action of each regenerator upon the furnace, whether in supplying airor gas or receiv ng the products of combustion from the furnace, is

equalized throughout the entire length of the furnace, V I Furnaces of, the kind under consideration are commonly employed for the reduction of ore and for smelting operations, and. in the furnaces shown in Fig. l crucibles 16 and 17 are indicated in the position that they assume in the furnaces to be heated by the action of the burning ases therein. As clearly shown in Fig. 1, eac of the passageways extending upward through .the partition 11 is branched at its upper end so that one path extends to'the furnace 9 and the other path extends to the furnace 10. In this manner, each passageway serves to simultaneously supply to each furnace air or gas or to receive from both furnaces the products of combustion, as the case may be. Since the outlet openings of the passageways are in the same vertical wall of each furnace and are immediately adjacent to .made by the passageway 22.

through the partition 11, the distance that i the burning gases and products of combustion are required to travel through the passageways in'going from the supply regenerators to the receiving'regenerators is reduced to a minimum.

As shown in Fig 3, the passageways or flues 5, 6, 7 and 8 are extended beyond the furnace and regenerator to the controlling mechanism indicated in plan view in Fig. 3 and in elevation view in Fig. 2. This controlling mechanism is constructed as follows: The central flues 6 and 7 are branched and diverted outwardly in the manner indi cated in Fig. 3 and terminate in either side of a valve casing 18 located immediately over the ends of said flues. The casing 18 contains a butterfly valve 19 secured t0 a shaft 20 extending through the casing and provided with an operating wheel 21, by which the valve may be caused to assume either the position shown in full lines or the position shown in dotted lines in Fig. 4. A passageway 22 is provided in the masonry immediately below the valve 19 between the ends of the flues 6 and 7 which passageway extends into the bottom of the stack 23, as indicated in Fig. 3. The flues 5 and 8 are also spread outwardly so as to pass around the spread ends of the tines 6 and 7 and are continued beyond the stack 23 and terminate below and cpmmunicate with either end of a valve casing 24 similar to the valvecasing 18 and rovided with a similar valve 25 adapted to be operated bv a hand-wheeel 26. The valve casing 24 communicates by means of a passageway 27 in the masonry below. the valve 25 with the opposite side of the stack 23 to that with which connection is The valve casings 18 and 24 have located above them chambers 28 and 29 communicating with the upper part of the corresponding valve casings through openings, as shown: for the valve casing 18 at 30 in Fig. 4, and these chambers are supplied with gas and air respectively by any suitable means, not shown, and the gas and air as thus supplied may be under any desired pressure. It is immaterial which chamber' is supplied with air and which supplied with gas, as the operation of the mechanism is the same in eitherevent. The operation-of the device is as follows: Assuming that the chamber 28 is supplied with gas and the chamber 29 with air and that both of the valves or dampers 19 and 25 are in the position indicated in Fig. 4 in full lines, gas is supplied to the flue 6 and air is supplied to the flue 5 under such pressure as may be necessary to properly supply the furnaces through the regenerators. At this time both of the flues 7 and 8 are in communication with the stack 23. The gas supplied to the flue 6 is sent through 2 to the third outlet opening, designated 13, of each series of outlet openings in each of the furnaces tand 10; the air supplied to the tlue .3 is sent through the regenerator 1 to the fourth outlet opening in each of the furnaces, designated 12 in Fig. 2, and at each pair of outlet openings'lfl and 12 combustion of the gas takes place, being supporied by the a" referred to. The gases of combustion pass downward the regenerator for this condition in -each furnace to the openings 14' and 15 at the upper era. of the passages ll and 1.") by which die exhaust gases are conducted to the regenerators 3 and 'l respectively. After passing through these regeneratois, the exhaust gases pass through the lines T and cl. and thus out into the stack The continued operation of the furnaces for this adjust ment of the valves 19 and 25 continues until the checker-work in the regeneiators 3 and 4 has: been heated to a point where it will not cll'ectiwly absorb more of the heat of the exhaust gases. at which time the valves 1) and :55 aic turned to the reverse position, which connects the I'lucs 5 and t1 hit the stack and supplies gas to the lluc T an-l air to the fine 8. For this condition of the valves. is delivered to each of the furnace through the fird if each series of openings, dewignatcd l4. and air is supplied to each furnace through the seconl 1' each series of passageways, designated l and combustion now takes place between each such pair of openings in each of the fur uaees and the produ ts of combustion pass upward around the retorts 1(3 and ii to the other p:u-:-a;j;e\';:iys l2 and 13* of each se ries. from which the products of conilmstion a.e communicated through the passageways 12 and 13 to the iegi rators 1 and 2 respectively to heat the tllt'tj.- l'--\\ orl; in said regenerators. Rfter iaissing through this (llGCliQl-\\U1li. the gases of combustion pass outward through the fines Sand (3 to the stack. It will be observed that for this condition the gas and air supplied to the furnaces is caused to pass through the previously-heated checker-work of the regenerators 3 and -'l, and thus preheated to a considerable degree before the gas is burned,

which results in utilizing a large portion of the heat of the gases of combustion. The reversal of the vahcs 19 and 25 may be made at any desired intervals, so as to secure the most effective operation of the apparatus.

While in the drawings there are two separate shafts shown supporting the valves or dampers 19 and 25 so that they may be inde pendently operated, if for any reason it is desired to do so, since these devices are pref erably operated at the same time, they may be. connected by any desired mechanism so that the operation of one o ti esev lves or dampers will operate the other, as, for eX ample, by a continuous shaft supporting both of them or any suitable gearing connecting the separate shafts.

As a result of the construction and operation above-described, it willbe observed that all of the parts involved in supplying gas and air to the furnaces or in removing" the products of combustion therefrom are located on a lower level, thus making the c0mmunication between the supply chambers and the regenerators and between the regenerators and the stack as direct as possible. Furthermore, it will appear that the regenerators may be constructed so to be of substantially the same width as the furnaces located over them, as a result of which the maximum width of the structure need not exceed that required for the furnaces themselves, and thus a considerable saving in floor space is effected.

lVhile I have shown my invention in the particular embodiment herein described, I do not, however, limit myself to this constr'uction, I may use other and equivalent constructions without departing from the spirit of my invention.
