applicati@ sied February 14, i921. serial No. 444,790.

The invention comprehends improvements of especial utility in thecoking retort oven art; and also comprehends certain iinprovenients applicable to coling retort ovens ofthe Well-known Koppei's cross-regenerative tvpe exemplified in the patent to H.

Hoppers fo. 818,033 dated April 17, 1906.

The invention has for an object to provide a combination coke oven with a novel and highly efficient system of combustion in the thune or combustion iiues of the heating walls, to the end that' the constant flame principle described and elaimedin niy copending application for Letters Patent for a (-oking retort oven tiled April 10, 1920, Se rial No. 372,999 is incorporated in a coking retort oven, whether coke voven gas be einployed as the oven fuel, or a vspecial generator gas, such as producer gas. Furthermore, the tivo gases may be burned concurrently, in which case the producer gas op crates to dilute the coke oven gas. The invention retains, with all of its advantages, the regenerative system of conserving the Waste heat from the lues and utilizing such waste heat for preheating the air that enters the flnes to support combustion of thefuel burned therein.' In other words, the invention combines the regenerative system with its attendant periodic reversal of flow, in such a way in the novel flue system that flame is maintained constantly in all the fines of each heating wall, regardless of Whether the fuel be the coke oven gas distilled from the coal coked in the ret-Orts or oven chambers or the fuel be an alternatively employed special generator gas, such as producer gas, with the result that vuniformity in temperature of the heating Walls is promoted, extreme temperature variations are eliminated, and the charges of coal Within the several coking chambers are subjected constantly throughout their entire extent-to the high temperatures of burning flames and no retardation of the carbonization process results from the reversal of flow through the rcgenerators. By the invention, the eiliciency of a coking retort oven is greatly promoted, notwithstanding the fuel employed, the carbonization process is carried on more evenly, with greater facility and ina shortcr time than has been heretofore ossible, and temperature fluctuations throng iout the system are greatly reduced. y

In addition to the general objects recited above, the invention has for further objects such other improvements and advantages in construction and operation as are found to obtain in the structures and devices hereinafter described or claimed.

In its present embodiment,the invention is incorporated in a coking retort oven or colic oven battery having` `features` of the well-known Koppel-s cross-regenerative type cxcniplilicd in (lic paient to H'. Koppers hereinabove mentioned, which regenerative colic oven includes in its construction crosswise (.Xtending' parallel heating walls constituted of llame or combustion fines, elongated coking chambers or ovens intermediate the heatingr walls and parallel therewith, and crosswise extending' rcgenerators located below the coking chambers and the heating walls and parallel therewith. For convenience, the present description will be confined to this use of the invention; features of construction are, however, readily 'susceptible of other valuable applications; consequently, the scope ot' the invention is not confined tothe specific use and specific einbodiment herein described as an illustrative example. v

Referringv to the drawings: rlhere are illnstrated views of a coke oven battery of the by-product type, such as has been hereinbetore mentioned, which battery embodies in its construction a plurality of crosswise elongated heatingA walls 1l and a plurality of intermediate crosswisc elongated vertical cokingnr chambers l2. The heating.,r Walls 11 form the side walls ol the respective coliing chambers 12, as shown more particularly in Fig. l, and together with the coking chumbers are supported by the heavy gas tight supporting walls o't the series 13 and the other gas tight supporting walls of the series 14C. Both series 13 and 14; of such supporting walls extend crossvvise of the battery and are located, as shown, below the coking chambers and the heating walls, and collectively form the main support for the entire super-structure of the oven battery. These supporting walls are themselves firmly supported upon a flat mat or platform which constitutes the sub-foundation on which the entire battery rests.

The coal to be coked is charged into the several coking chambers or ovens 12 through charcing holes 15, indicated by dotted lines in tie top 16 of the oven battery, positioned directly above the ovens or chambers 12, as shown in Fig. 1. These charging holes 15 are equipped with vthe usual removable covers, not shown, which are removed when charging,- any of the several ovens and placed in position to close the tops of the ovens during the ent-ire e'okingl operaimanes into the usual gas collecting main which carries the distillation products to the by.

product recovery apparatus.

Heat for cokinp, the charges of coal in they several ovens or chambers 12 is derived from the heating walls 11, which, as betere inentioned, extend crosswise ot' the battery at the Isides ot the colcinp; clnnnbcrs. The con-v struction and the functimiinp,` olf these neat.- ing walls constitute ini iortant features nl the present invention. liteterrinn' now more particularly to Fig: 5, nach heating wall is constituted of two series, 17 and 1S, ol' vcrtical flame or combustion fines, the lines ol." one series 17 alternatiinnv with the llucs ol the other series 18. When one series ot such fines is operatingf for uplow, that is to .say burning upwardly, the other series of such lues is operating t'or downtlow, that is to say burning downwardly. Arranged along one side ot' the central axis of each heatingT wall 11 and alternating with the individual lues thereotl are two series ot' vertical channels 19 and 20, the channels of one series 19 alternating with the channels ot the other series 20. Also arranged on the opposite side of the said cent-ral axis of each heating wall and alternating with the individual fines thereof, are two furthe-r series of vertical channels, 2l and 22, the channels ot' the series 21 alternating with the chan.- nels of the other series 22. With the above described construction, each heating wall 11, is equipped with two series ot' llame or combustion fines and with tour series ot vertical channels, the several series ot fines and channels ot each heating wall being each controllable both as to direction and vcharacter of the low independently of the other series ot channels and fines as will be more fully explained hereinafter.

The crosswise regenerators ot the retort oven or battery are located below the aforesaid heating walls 11 and colring chambers 12 and in the present inst-ance extend in )arallelism between the supporting Walls atoresaid. According' to the invention, the supporting walls of the series 13 are grouped into pairs 23,11s shown in Fig'. l and the snpporting walls ot the series ll are respectives ly located between individual members of such pairs, whereas the supporting wallsI 1- are omitted between adjacent supporting walls 13 of different pairs. Both series 18 and 14 of supporting walls form the side walls of regenerators, and, with this copstruction, there is thus provided a series 24 of regenerators that are respectively ,located between adjacent support ing 'walls 13 of different pairs, a series 25 of regenerators that are respectively loiii heated b v the hot combustion products that draw ofi1 from the flame or combustion linesv hereinabove mentioned and then impart such heat to the medium that they feed into these liame flues.

In accordance with the invention, each rc- ;:encrator ot' the series 24 is communicably connected bv aserics of ducts 29 with the .flame lines o l' the series 17 of the hea-ting wall located to the right of such regenerator, and

isalso con'ununicahlv connectedl by a series of ductsl it() with the lametlues of theseries 18 of the adjacent heating wall locatedto the lett ot' such regenerator. ln addition. each regenerator ot the series 21 is conununicably connected bv means of a series ot lducts 31 with the series 19 of vertical channels ot the heating wall to the rightand is also communie-ably connected, by means of a series ot' ducts 32 with the series of vertical channels 21 otthe heating wall to the left. Each regeuerator of the series 25 is communie-'ably connected b v means ot a series of ducts 33 with the 'flame tlues of the series 17 of 'a single heating Wall located above such regenerator` and is 'also con'nnuuicably connected Alll by means ot a series of ducts 34 with the vertical channels of the series 22 ot' the same heating wall. Each regenerator of the series 26 is communie-ably connected, by means ot a series ot ducts 35, with the heating flucs ot' the series *18 of the single adjacent heating: Wall located above such regenerator, and is also communica-bly connected, by means of a series ot ducts 36 with the vertical channels of the series 2O of the same beating Wall. The purpose ot the above described duct connections between the sev-- eral regcnerators, vertical channels and ues will appear in the hereinafter given description ot the operation of the battery.

Refer-riorlr more particularly to Figs. 2. 7 and 1l` there are provided above the in'- dividual tlues of the series 17 of each heating 'all 11, a series ot chambers 37 and above the flues of thel series 18 a series of chambers 88. The Haes of the series 17 of cach heating wall respectively communicate with the chambers of the series 37 through ports 39, and the fines ot the series 18 respectively communicate with the chambers of the series 38 through ports 40. As shovvn in Figs. 2 and 7 each of such chambers 37,

lends with a series ot' chambers 44; and the ot each heatii'ic wall, is comn'mnicablyl connected with the adjacent chamber 3S hv means ot' .a horizontal duct 41. Thus, through the chambers 37 and 38 at the top of the tlues 17 and 18 of' each heating Wall 'and the4 ports 39 and 40 and short horizontal ducts 41, the individual lues of the series 17 are com'municabl;7 connected With the adjacent' individual lues of the alternate series 18..

{eter-ring more particularly .to Figs. 4, G and 11, the series of'vertical channels 1S) of each heating` wall respectively are communicably connected at their top with a series ot' chambers 42; the series ot' channels 20 are respectively cominunicably connected at their upper ends with a series of chambers 43; the series of channels 21 are respectively communicablyv connected at their upper series ot channels 22 are respectively comm'unicably connected at their upper endsl with a series ol chambers 45. Nozzles 4G connect'the channels otv all series of each heating Wall with their respective series ot communicating: chambers.. The series ot chambers 42- are communicably connected byjmeans. ot a series of ducts 47 withthe series of tlues 18; the series-of chambers 43 are comnumicably connected by` a "series 0I ducts 48 with a series of tlues 17 the series. ot chambers 44v are also com'n'xunicably connected with a series ot' tlues 1 7' bya series ot ducts 49; andthe series ot chambers 45 are also conununicably connected with the series ot llucs 18 bya series ot ducts 50. lVith this construction, the tops of the two series ot channels 20 and 21 are communicably connected individually with the individua'. thies ol the series 1.7: and the tops ot' the two series ot channels 19 and 22 are cornmunicably connected individually with the individual tlues of the series'18.

Extenolinfy` crosswise of the battery, on each side of the longitudinal partition 5.1 and located beneath the heating Wall 11 thereabove is a pair of gaps channels 52 and 52. These channels 52 and 53 are for the purpose of supplying coke oven gas to the lues, when coke oven gas is the medium employed for fuel. and communicate respectively by means of a series ot' ducts 54 and 55 with the bottoms ofthe flame flues ot the series 17 and 18 in lthe heating wall above such pair of gas channels. Thatl is to say, the. ducts 54 of the channel 52 lead into the flame fines of the series 17, and the'ducts 55 of the gas channel 53 lead into the flame flues ot' the series 18. As shown in Figs. 1, 2, 3, 4, and 11, a-series of access lues 56, .in each heating wall, extend from the chambers 37 above the tine series 17 to' the top ot thc oven battery, these access fines affording a means of communication from the top of the battery with the interior of the chambers 37 and the tlues Hill 17 therebeneath. A similar series vof access tlues 57 extend from the chambers 38 at the tops ot the fiue series 18. Further similar series of access fines 58, 59, 60 and 61 extend to the top of the battery from the series ot' chan'ihers 42, 43, 44 and 45 which are respectively located at the tops" of the series 'of vertical channels 19, 2t), 21 and 22. Normally the access tlues mentioned aboveI are closed hy suitable cover plates. As shown in ltig. 2, the access tlues ol" the series 5G above. the chambers 257 alternate with the access fines otl the series 57 above the cha1nbers 38. The access tlues et the two series 56 and 57 may thus be grouped into pairs each pair comprising adjacent tlues ot both series. Between each pair of access fines 56, 5T is a vert-ical gas supply duct (i2 extending- 'from thetop of the battery to the horizontal duct 41 that connects a pair otchambers 37 and 38. The several gas ducts (32, ot each heating wall terminate, as shown in Figs. 2 and 11 in flaring nozzles 6?, through which tuel gas may flow either into the series of chambers 3T and the connected flues 17 vor into the series of chambers 38 and the connected tlues 18. each duct is located at the top ofthe cross connecting duct 41 between two chambers 37 and 38, and, because ot the coincidence of the greatest cross-sectional area of the nozzle with the discharge end thereof, and the inclined walls that extend downwardly in opposite directions toward the respective chambers 37 and 38, the gas may pass Wit-h facility either into the fines 17 or into the tlue 18. The series of gas-supply ducts 62 in the top of each heating Wall are supplied from a coke oven gas main 64 suitably supported over each heating Wall, as shown in Fig. 1, and provided with a series of gas guns 65 Which enter the inlets of the aforesaid ducts 62. Suitable supply means is also provided for supplying eolie oven gas, at will, to the bottom coke oven gas channels 52 and 53.

`With the above described construction, constant tiame or combustion is maintained in all of the flame or combustion tlues ot each heating wall, irrespective et Whether the' How is up or down in a series ot such fines and irrespective ot the type of gas'einployed as fuel.. According to the present l' embodiment of the invention, when a series ot fines 17, tor example, ot a heating Wall .is being fed with gas ot either type from the bottom, the opposite series of' alternate ues 18 in the same heating AWall is concurrently being fed with fuel gas from the top. In this manner, upburning flames ot either producer gas or an alternatively employed coke even gas is maintained in all the fines of one series ot the heating Wall,

lWhile simultaneously downburning flame is maintained in all the alternate ues of the The flaring nozzle 63 ot other series ot the same heating wall. Hence, throughout the battery, combustion is maintained in all ot' the fines, notwithstai'iding reversalot flow through the regener'ators and in the fines, the manner et which will be hereinafter explained, with the result that each heating wall is being constantly heated from side to side of the battery and from top to bottom ot' the heating Wall by constantly burning flan'ies, teix'ipeature conditions are equalized throughout the battery or plant as a whole, and the coking process proceeds uniformly without. interruption from end to end and from top to bottom ot each coking chaniber. The combined up flame and alternate downfiaine in each heating Wall results in a considerable extension ot' the capacity ot' the wall to maintain telnperature in a vertical direction, thereby permitting an increase in the height. et the heating walls, with a consequent increase in the height of the coking chambers and their individual coking capacity.

l'n order to illustrate advantages and novel features ot' the invention and in exposition ot' the above general statements ot operation and resi.1lts,the following detailed description ot both' protjlncer gas and coke oven gas operation otl a roking retort oven, constructed in the manner above described and illustrated in the accompanying drawings is now given.

The operation ot the battery, when using a, special generator gas, such as ordinary producer gas, is as follows: Vhen burning producer gas as the battery fuel, alternate regenerators ot' the series 24 operate as inflow producer gas rege'nerators; the adjacent re generators ot the series 26 and 25 which are respectively lo :ated on the left and the right of the inflow producer gas regenerators, opcrate concurrently as inflow Vair regenerators. The remainder ot the regeneratorsot the series 24, 25 and 26 operate concurrently as outtlow regen craters. For convenience in description, the inflow producer gas regenerators ot one reversal period are designated on the drawings by the rt'it'erence character l), the inflow air regenerators ot the series 26 and 25 are designated by thereterence character A, the outtiow reguierators ot the series 25 and 26 aredesignated by the reference character W, and the outflow regenerators ot' the'seres 24 are designated bythe reti-rence character E. As stated, the intlow producer gas regenerators P alternate with the outtlow regenerators E, and the air regenerators A are respectively located on opposite sides ot the alternately arranged producer gas regenerat-ors P. i

With the parts operating as above stated, the producer gas flowsinto the several producer gas regenerators P, while air ilows into the several air regenerators A. As each producer gas regenerator supplies the upburning tlues ot two heatlngwalls respectively lon located on the right and the left of such producer gas regenerators as well as one se ries ot vertical vchannels of each heatingwall, the producer gas regenerators are made of substantially twice the capacity of the air regenerators, the latter feeding the upburning fines and one series of channels of only a single heating wall. 'lhe producer gas from the regenerators l flows into lues of the series 17 ot' thcl heating' walls to the right ot' such regeneratms*and also into the flues ot' the series 18 of the heating; walls to the lett ol such regenerators, the series ot fines 17 and 18 ot' ,such right and left heating walls operatingas upburning fines. The air regenerators A of the series 25 supplythe uphurning flues 17 which are located in the right side of the heating walls, and the air regenerators A of the series 26 supply the upburning flues 18 which are located in the left side heating walls with respect to each producer gas regenerator P. Thus the series otv tlues 17 of alternate. heatingr walls are burningr upwardly, while the series ot tlues 18 of heating walls that are intermediate such alternate heating' walls aforesaid are burning up a1dly.

During this operation, the series ot' channels 19 of the alternate heating walls containin; r the upburning flues 17 are operating as upt'iow channels and are receiving producer das troni the ducts 31 ot' theproducer gas regenerators; concurrently the vertical channels 2l ot' the interniediate heating walls containing the upburning lues 1B are operating' as upfiow channels and are receiving` producergas troni the' ducts 32 of said producer gas regenerators. The air regenerators A o1' the series 25 are teedinpr the vertical chai'niels ot' the series 22 of the said :alternate heating walls and the air regenerators ot' the series 26 are feeding the vertical channels 20 ot' the said intermediate heating' walls. ln the alternate heating walls the waste Irases trom the npburning ues 17 paw into the chambers 37 and thence through the horizontal ducts 41 into the chambers 38 and downburning fines 18; in the said intermediate heating walls, the waste gases from the upburning lines 18 pass into the chambers 38 and thence through the ducts 41 into the chambers 37 and downburning flues 17. The channels of the series 19 of the alternate hea-ting walls feed producer gas to thechamhers 42 and thence 'through the ducts 47 to the downburning lues 18, While the channels 22 ot such alternate heating walls feed air to the chan'ibers 45 and thence through the ducts 50 to said downb'urning fines 18. In the intermediate heating' walls the producer gras to the downburning lncs 17 is supplied to the channels 21. chambers 414. and ducts 4S) and the air troni the channels 20. chambers 43 and ducts 4h.A Consequently alternato lues ot' every heating wall are uphurning. while the other Fines are down'burniug, there being a continual supply of producer gas and air whether from the bottom of the lue or from walls part of the waste products from the upburning fines 18 -ass through the ducts 5t) and 47 into the ciambers 45 and 42 and thence downwardly .through the channels 22 and 19. T he waste gas regenerators E receive the waste gas downtlow trom the flue series 18 of the alternate .heating walls, which are located on the lett of such waste, gas regenerators and also from the series ot' channels 2l; such waste gas regenerators also receive the waste gases from the fines 17 and channels of the series 19,v of the intermediate heating .walls on the right of such regenerators. The Waste .gases from the downburning tlues 18 and downow channels 20 of the alternate heating walls. pass into the Waste gas regenerators of the series 26, and the downflow from the downburning tlues 17 and downflow channels 22 of the intermediate c heating walls passes into the waste gas regenerators ot' the series 25.

On reversal of the battery, the several regenerators of the series P become waste gas regenerators together with their connected series ot flues and channels; the several regenerators E with their connected series ot lines and channels become inflow producer' gas regenerators; the several regeneratiors of the series A with their connectedseries o'l' lues and channels become outflow Waste gas regenerators; and' the several regenerators ot' the series W with their connected series of flues and channels become inflow air regenerators. The reversal of the battery is accomplished by means of the usual reversing mechanism employed by those skilled in the art. v

When em loying coke oven gas as the bat tery fuel, airY instead of producer rras is al v lowed to flow into the ino'w operating' re-` generators of the series 24;. This furnishes the larger volume of air required for the combustion of the relatively richer .coke oven' gas, inasmuch as the supply of air from the inow regenerators of the series 24 is in addition to that furnishedby the air regenerators A- of the series 25 and 26. The ow, when operating with coke oven gas, through the several fines and channels isr exactly the same as that which takes place in producer gras operation. Consequently it is not necessary to trace out the flow of the air and waste heat through the channels and lues in coke oven gas operation. During coke oven gas operation, the coke oven gas ducts 52 and 53 supply coke oren gas to the upburning flues of the series 17 and 18 of the respective alternate and intermediate heating walls; the coke oven gas is drawn through the ducts 62 into the downburning lues 18 and 17 of said respective alternate and intermediate heating Walls. 0n reversal of the battery, the flow is reversed in exactly the same Way as in producer gas operation, that is to say, the air regenerators become waste gas regenerators and the Waste gas regenerators'become air regenerators, the upburning lines 17 become downburning Hues and downburning lines 18 become uplourning tlues.

Because of thev fact that some of the Waste gas enters the top of the downburning tlues, Whether the oven be operated with producer gas or coke oven gas, the flames in the downburning iues are consequently lengthened. This has the effect of increasingthe volume of llame of such down burning ues and consequently increases the flame heated area of the heating walls; Such lengtheingI of the flames permitsthe inaking oiv very high heating Walls, while preserving substantially uniform temperature conditions throughout a substantial extent of such walls. The lengthening of the flame in the downburninp, tlues` moreover, prevents an intense flame concentration in the upper extremities of the heating flues where it is most desirable to keep the temperature relatively low, in yorder to avoid destruction ot' the gases of distillation which arise from the charge of coal in the coking chambers between-the heating Walls.

Furthermore. the coke oven gas may be supplied to both the uplonrning and .doWnburning tlues, in which case the producer gas supplied to both such series'of fines functions as a diluent to the coke oven gas. (')r the coke oven gas may, at will be supplied only to upburning and downburning filles. 'lhc waste ,ons may he regulably supplied to the downhurning' lines to further dilute the flames in such tlues.

Althougl'i, as it above appears, the reversal ot' flow through the battery takes place lon- ,e'itudinally thereof, instead ot crosswise of the battery as described in the patent to H. Koppers hereinbetore mentioned, it is neven theless preferable to employ, crosswise of the battery, pairs of end to end positioned regencrators. the regenerators of each 'pair respectively extendingr from opposite sides of the battery inwardly to the central diriding partition 51, shown in Figs. 2, 3, and 4. This construction reduces the length of the rcgenerators crossvvise of the battery and the volume ol flow which must ass through each rcgenerator per unit of time, and thcreliy facilitates control oi the flow through the regenerator and promotes equality and distribution through the ues Leiaoee and channels connected with the regenen ator.
