COKE-OVEN.

Specication of Letters Patent. Patented ADI. 11, 191 1.

Application. tiled April 21, 1910. Serial No. 556,840.

To all whom it may concern l Be it'known that I, Gns'rAv SCHWAB, a subject of the Emperor of Germany, residing at Chicago, in the county 'of Cook and State ot Illinois, have invented a new and useful improvement in Coke-Ovens, of which the following is a specification.

My invention relates particularly to ovens adapted to produce coke from coal; and my 1i) primary object is to provide an improved oven-structure involving the use of improved heatingtlue construction between the series of ovens employed in the structure, whereby .the heat employed for coking purposes may be more effectively and more completely utilized, whereby the oven-structure will be less liable to injurious ell'ccts .from contraction and expansion, the life o't the structure will be lengthened, and, in genso eral, coke may be produced more cconomt cally than in ovens ot' known construction. The invention also renders it possible to construct the ovens ot' any desired 'size without necessitating special reinforcement, und Without loss of economy in operation.

The invention involves, in the form illustratcd, a construction wherein are employed a series ot ovens Whose lateral walls are formed. by specially constructed vertically disposed heating tlues so designed as to connnunicate heat to the ovens in the most. ellicient manner and to withstand etl'ectivcly the contraction and expansion incident to the reversal of the course of thc products ot combustion usual in an oven ot' the regenerative type.

The invention is illustrated in the pret'erred embodiment in the accompanying drawings in which- Figure 1 represents a broken sectional View of an oven constructed in accordance with my invention, the section being taken parallel with one side or t'ront ot the oven, 'as indicated at line 1 of Fig. 2; Fig. a transverse section taken as indicated at line i? of Fig. l, the section cutting one oi:l the oven chambers; Fig. 2l, a broken longitu- `dinal section taken approximately :ns indi? cated at line -3 ot' Figs. 2 andl, thc section at the upper portion ot the figure boing taken on a stepped liuc, as indicated by the broke-n walls, the purpose bcing to show thc inspcctitm openings through thc upper Valls o't"`the structure as well as the charging openings thcretlnough; Fig. 3, a broken section on an enlarged scale, showing .the flue construction, the section being taltcn as indicated on line il ot Fig. (t: Fig. 1t, a transverse section taken as indicated at line Lt of Fig. 3, this section passing through a vertical flue series separatingntwo ovens; Fig. 5, a broken'horizontal section, taken. as indicated, on line 5 ot Fig. it; Fig. G, u broken plan view showing a fragment ot' the flue construction.

ln the construction illustrated, the ovcnstructure comprises a base wall 1 and lateral walls 2 and Q; a series of ovens 3 having openings 4C through said lateral walls; a vertical .[tuc. serios 5 between each two adjacent ovens and forming the lateral walls of said ovens; longitudinal gas mains T at euch side or front of the coke-oven structure, from cach ot which rises a Series of gas pipes 8, and a series oit' gas pipes S admitted to be alternately used, said gas pipes being controlled, respectively, by gas cocks 9 and tl; a laterally `disposed chamber 10 'Ior cach gas main `and the gas pipes rising there from; a pair of longitudinally extending main conduits 11 and 11 which extend through the base of thc structure and are locntednear the sides of thc structure, and which servealternately as air admission and combustion products outlet conduits; a series ot transversely extending rcgcncrator conduits 12 located in the base 1, ol the structure beneath alternate ones ot the ovens 3. and connnunicating with `the main conduit l1 a series oi" similar regenerator couduits or, chambers 12 located beneath thc. remaining alternate ovens and communicnting with thc main conduit '1l; a series ot comluits` 13 connecting thc conduits 12 with the main or loi'igitudinul conduit 11; u series o't' conduits 125 ctmnccting the conduits 12 with thc longitudinal conduit 11:

vulves 13" controlling the conduits lil. and valves 151" controlling' the ctmduits ilzlr; n series ot comparatively small conduitsl 'lf-t disposed just beneath the bottoms ot the ovens and above the conduits or regenerative clutmbcrs 12; a series o't alternating conduits ist disposed above` the rcgcmrutirc conduits 12 und beneath the bottoms ot' the corrcspomling ovens; passages 15 through which the conduits 12 are in communication with the conduits 1.4; passages 15 through which-the conduits 12 are in communicaY tion with the conduits 14; two series oliintit , inspected..

clined passages 16 through` which the con-,

duits 14 communicate` with alternate Vertical lues oi"l the two flanking heating iiue series, and 'two series of inclined passagesV 16a through which the conduits 141il communicate ,with alternating'vertical heating iiues of the two tlankin heating flue series. l

Gdn'erally speaking, the Walls of the cokeo'v'en" structure are composed of brick, butv any-suitable material may be employed. As shown, the base Wall l has, in itsl'ateralsurfaces, openings 17, through Which, in Fig. 1, may be viewed the .Walls of the conduit 11, and the view-openings 6 leading to conduits 12 and 12a. in practice,'the openings 4, at the ends oi' the ovens, are closed by doors (not shown). Through the upper Wall'f" the structure extend charging openings 18 leading to the ovens and vent` openings 19 communicating with the oyens;` also view openings 20 enabling the Vvertical lines to be Each flue seriesis preferably constructed in themanne'r vshown inlqdetail :ln-Figs. 3f, 5, 6. As thus constructed," each flue series is provided with ayerticalseriesof lfines 21 which, in pairs,=`alterna'te Withthe pairs of a vertical series oftlues l22. The-,Hue construc` tion is such that eachfluehas :triangular verticai Walls, andv the referred manner of securing such triangu a1' walls is to construct two substantially` parallel walls 23 which are joined by oblique walls 24. The

oblique Walls 24 and the parallel walls 23, in

part, are formedl by``4` means, of Y-shaped bricks having a stem or'bas'e25 and arms 26. In laying the .Wa-11s, the "stems or base or tions 25 alternate .with 'simple or straight bricks 27 at one Wa11023, While the entremities of the arms abut against simple or straight bricks 27 in the opposing Wall 23.l In the next course, the stems or base rtions 25 are laid as a part-of the other Wal 2,3, beJ linnr placed so that ythe base 'portions'o'f-the 45' arms projecting from eachfstem'will lie over the free end portions of thearms ,of thelni-l derlying course of Y-shaped bricks. As thus constructed, the Y-sha-ped bricks vareirmlyu bound together and also bound to the par-:

allel Walls, it being understood that the Y;l

shaped bricks of one course bear Whatmayv be termed a. staggered relation to the vY- shaped bricks of the next course. ,The iues 21 communicate through 'the assages 16 with the conduits 14, and the ues 22 conimunicate through the passages I6 with "the conduits 14.

' Each. vertical gas pipe 8 is provided l.with a pair of inturned branches 29, and 30 which communicate with channels or gas passages 31 and'32 respectively. The channels-3l are disposed directly beneath the heating iiucs and extend inwardly from the lateral surfaces of the structure y.appronimately` onequarterof the distance across; and the pasthe spaces sagen 32' communicate with channels 33 which are separated from each other-,1 by a Wall 34 and fromthe channels 31 bylwalls The channels 31 and 33 communicate with the vertical heating dues 21 through inclined passages 36. The gas pipes 8a coinmunicatc through branches 29a and 30 with passages 31a and 32 similar to the passages 31- and 32 and lying close beside them, the passages 32a communicating with passages 33 which lie side by side with the passages 33 and are similar thereto. The passages 31 and 33 communicate through inclined pasl sages 36a with the vertical iiues 22. K The operation will be readily understood from the foregloing detailed description. We may assume t e conduit llto be placed in' communication with the smokel stack or chimney and the conduit 11 to be placed in communication With the atmosphere 'by the usual means (not shown) As 4thus arranged, 'assuming the valves 9 controlling the u'erticafl gaj'sjjpipes 8 to be opened, as by means of a chain 37 gas will be supplied to the channels 31 and 33, whence it willlpass through the passages 36 to the vertical heating fines.` 21. At the same time air Will be drawnf throu h the longitudinal conduit 11 and cross conduits 12, whence it will pass through the passa" S15 to the smaller cross conduits 14+. and t ence through the inclined passages 16 to the vertical flues 21, Where it will unite with the as'to form the prodilcts'of combustion,.the urning gases then passing through 38 at the upper ends of the Walls separating the fines-21 from ,the lues52'2, as `indicated in Figi-4, thence down through the fines 22, the passages '16?, the small cross y conduits 14, and the passages 15 to the .lar era'cross conduits or regenerators 12a,- an thence to the longitudinal conduit 11' vwhich is in4 communication with the chimhey. After' o eration in this manner for a 'predeterminedp' eriod, the operation is re- `versed, the longltudinal conduitll 'is placed in communicationwith the chimney and thc -conduit 11a is placed in communication with lthe atr1'1os1: here. The as cocks 9 are then lclosed and the gas cocsQ opened, Whereupon the combustion begins in the' vertical flues 22 and is continued by a down draitl through the flues 21, the outlet being through the inclined passages 16, the small cross conduits 14, the passages 15, the large cross conduits or regenerators 12 and finally through 120 the longitudinal'conduit 11 to the chimney.

It will be noted that by reason of my im proved flue construction the heat is evenly distributed to the ovens ankingtheiiiie v series, the ilues are soarranged as to enable expansion and contraction to occur without injurious results, the Walls being mutuallybracing, and ythe'most eiicient use is made of thehcat units generated by the burning'.A gases. j

` derstood therefrom,

lVhile the invention -is illustrated in connection with a coke-oven employing vertical heating fines and horizontal ovens, it will,`

ings 39 which are in alinement with view openings 39a 1n the alternating wall extensions 40 at the upper ends of, the tlues. View openings 41 extend through the upper walls Ll2 which cap the fine series, the view openings 41 communicating with the enlarged openings or chambers 20 shown in Fig. 3 and which have heretofore been mentioned. The chambers 20 are covered by removable plates 43 giving access to the longitudinal chambers 20, The View openings 3S) are ordinarily closed and the openings 39 are too small to interfere with the draft of the heating fines, but are large enough to enable the operation to be viewed. The view-openings 41 are covered by removable bricks 43.

The foregoing detailed description has been given for .clearness of understanding only, and no undue limitation should be unbut the appended claims should be constructed as broadly as permissible in view of the] prior art.
