'/0 all wim/n if may concern.'

Be it known that l. Etunxn LncocQ. a subject of the King: of Belgium, residing at Brussels. in the Kingdom otv Belgium,

have invented certain new and useful lm provemcnts in Coke AOvens (and for which l filed application tor patent in Belgium on .luly Sth. 1916), of which the following is a specification.

This invention relates to coke ovens ot the kind in which horizontal coking chamg bers are combined with side-walls provided with vertical flues forming lateral heatmg chambers. said ovens having no regenerators and working with or without recuperation of the byproducts. v

A first object of my invention is to secure a regular and uniformcoking in the whole length of the coking chambers and conse- Aquently a more regular and uniform temperature than hitherto obtained in the said.A

coking chambers.

Another object ot my invention, in direct connection with the purpose just mentioned,

is to avoid that the fines, which are arrangedA in the heating chambers and which do not Y contribute to the heating but are used 'for the escape ot the burnt gases, should disturb the regular operation ot' the coking chamber.,v

'cooperate with l the lues of the heating And a further object of my invention is to reduce the loss of 'heat by radiation in the `an excess of heat the loss of heat by radiaf tion in some other parts of the oven,v for in# stance in that part which is `adjacentgto the heating fines at both ends ofv the 'heating chambers. i l. i

With these objects in View my invention essentially consists in some special arrangements and combinations of circulation channels and also of the conduits for the fdistribution of air and gas as'will beherein appended claims.

Figs.- 9.and l0 are two diagrammatic ,views showing, in vertical section. the distribution ofthe air into the vertical rfines of-lthe heating chambers. The said views do not correspond exactly to a section taken on line 3 4, Figs. 1 and 7, the air channels under thehearth, having been displaced to better illustrate the manner in which they chambers.

Thev coking oven which has been illustratedcoinprises, as ordinarily.,a foundation or lower struct-ure T provided with two ,galleries A for inspection, a central gallery Bfor the air, two laterai pairs of galleries D D, for the air and two collecting galleriesv C which are placed between the central gal- .lery Band the lateral galleries D D1 (Figs. .3 and 6).

The galleries A (Figs. 2, 3 and 6) provided ;for inspection, are open to the atmosphere at one end A, (Fig. 6) and are joined together at the other end by a gallery A2 (Fig. 8) communicating with the central galleryv B. This latter is closed at the opposite end B1, (Fig. 6). and communicates through little ducts b (Figs. 2, 3 and 6), passing under the collecting galleries C1 with the lower lateral galleries D which are in communication with the upper lateral galleries D1 whence the air is conducted through passages (l -into'air channels E. E2 E3 E4 (Figs. 2 and 7) which are arranged Fig. G is a horizontal section through the U as will be further described. f

,Above the foundation or lower structure T, just described, is placed the upper structure or battery of ovens comprising the horizontal coking chambers U (Figs. 2, -l. 5 and S) each placed betweentwo heating chambers V (Figs. 1, 3, 4 and 8). These heating chambers are provided with vertical fiues Yllwhich are numbered 1, 2, 3, 4, 28 in Fi`g'.'3, and form four groups: a first group comprising` the lues 1, 2, 3, 1, 5, 6, 7; a second group comprising the tlues 9, 10, 11, 12, 13, 14; a third group comprising the lues 15, 16, 17, 18, 19, 20, anda fourth group comprising the lues 22, 23, 24, 25, 26,

,'27, 28. 'Between the first and second groups,

a flue 8 is providedv for the escape of the burnt gases from .thesaid groups oflues;

mf .a similarflue 21 is provided between the third. group-and the lfourth groupvfor the escape of the'bu-rnt as from'the said grou s `.of flues. The said ues`8 and21, which will 2g. be called hereafter descending iues'co1n .'fh'eavertical iues1-28, are intercommuni veating lat their upper part as shown in Fig. 3,fan,d` are situated, as usually, under the channels N' .giving g access to the` .heating chambers.

P-''(Fig.j3)is aichannel for the captation of smoke, and Mare four 'dampers (shown only infdotted lines)"which" are used when it is desired to work the`by-products. f g

`22 to -28 must be suppliedwith gas and air -so as to secure the regular and uniform heat- "fing of the whole. length of each coking chamber` U.

This feedingv takes place asv The'gas'is supplied through gas pipes G,

whichrare'arranged in the galleries A for ..iifspectiom at the front and rear vends of theovens (Figs. 2 and 3). On eacl. pipe G` are branched, for each heating chamber,

three cocks r'. Oneof these cocks (on each side of the/oven) feeds through a pipe r, the first fiue 1 (resp. the last flue 28). The second cock (on each-side of the oven) feeds through a pipe r2 a gas chamber (t communieatin 2 to at one end ofthe oven and with the t iues 22 to 27 at the other end of the. oven.

The third cock feeds (on each side 4of the oven) through a pipe r3 a gas chamber a2` without recuperation of y sages f through passagesa1 with the luesA pipe r2 leading to a gas chamber 0:, and a' pipe r3 leading toa gas chamber a2.

The air is conducted through the galleries A A2 to the central gallery B, passes through the ducts Z1 into the lateral galleries D; then into the u'pperlateral galleries D1 and finally through the passages d, provided with dampers s intothe air channels under the hearth of each cokin chamber. These air channels E1 E2 E3 E (Figs. 2 and 7) are arranged in such a manner that each of them feeds a group of fines 1 to 7; 9 to 14; 15 to 2() or to 28.

Further the arrangement of said chan-l nels E, E2 E3 E4 is such that the'first air channel E', (Fig. 2) is supplied with air from the galleries D1 on the left hand side 'i of the oven, whilst the'second air channel E2, which is coaxial with the first channel El,

' is supplied with air from the lateral galleries D1 onthe right hand side of the oven.

Similarly, the third air channel E, is sup- .I

plied with Aair from the lateral galleries Dl on the left hand side of the oven and the fourth air channel E, from the lateral galleries D,l on 'the right hand side of the oven.

The operation of the oven is as follows:

[The gaswhich 4is supplied through the cocks i' to the end lines 1 and 28 and'also to thegas chambers a and (z2 combines in the vertica-lifiuesof the heating chambers with the air coming through the air channels E, E, E3 E, under the hearth (through A A.,

B b D and D, 'as already described) and which is supplied to the lues During the operation, the draft in each half heating chamber can be controlled by means of dampers g, placed in the passhown by dotted arrows in Fig. 3, pass into the descending fiues 8 and .21 and are conducted through the' passages f into the collecting-galleries C which join in a channel H conducting the burnt gases to boilers or similar apparatuses.

The burnt gases, circulating-as For the sake of clearness, in the several figures of the drawings, the way followed by the'gas is shown by full black arrows; the

l way 'followed by the air by thin arrows'and the way followed by v the. burnt gases by means of arrows traced in dotted lines.l

.It will be observed that in the oven c011- ystructed as described, any lossof heat resulting from theradiation of heat in the foundation o r lower structure is practically avoided, as indeed the collecting galleries C are the air circul atthe production of an excess vof heat in the end flues 1 and 28, said lues being supplied with gas through the4 gas pipes 1', which are independent of the pipes r2 r3 supplyinfr tenaces as n s to the gas chambers a a2, each feeding a group of six vertical fines.

rlhe air is uniformly distributed in each Vertical flue ofv any group-ot' tlues, which issupplied with air by a given air channel E,

E, E3 or E, as indeed,. asitwill clearly appear from an inspection 'of the diagrammaticviews, F igs, 9vand 10) lwhatever may be the vertical flue, the way followed by,the gas, (from the inlet of the air to the outlet of the burnt gases through the descendin flue of the group) is the same vfor the several lues of any group.

On the other hand, the arrangement of the descending lues or outlet tlues 8 and 2l (Fig. 3) for the burnt gases, between two vertical heating tlues 7 and 9-or 20I and 22, has the -result that heat will be transmitted by conductivity from the heating tlues 7-9 and 20-22 to said descending ll'ues in such a manner thatinsutlicient heating of the coal in the coking chamber will be avoided in the pai-trof the coking chamber in -front of the descending lues.

If it is desired to run the oven. .withoutv recovering4 the by-.products, the' four dampers M (shown in dotted lines Fig. 3) are closed.

Air is then introduced through the ver' tical openings N provided in the axis of the heating chambers y1n the upper part of the oven structures whilst the gas, resulting from the distillation. is sent in the upper horizontal channel of the heating chamber, through passages, not shown on the drawing -but provided between the charging openings Z and the channels 'N and P. Four circuits are then produced in each heating chamber: The burnt gases descend in the four iiues 1, 2, 3, 4., enter into the air channel E1 under the heart-h, re-asccnd in the three next fines 5, 6, 7 and escape through the descending ,flue 8; in the lsecond circuit, the gases descend in the tlucs 12, 13, 14, enter into the air channel E2, re-asccnd in the fines 9, 10, ll, and escape also through the descending flue 8.

The third and fourth circuits take place in a similar manner in the second. half of the heating chamber.

What I claim is:

1. In `a coke-oven of the kind described, horizontal coking chambers, heating cham- 'hcrs arranged on opposite sides ol each coking chamber, each ot said heating chambers being divided into a plurality of' flues, the said fines being arranged in groups of heating tlues with a single descending exhaust flue between 'adjacent groups with which the heating lines are connected` gas chambers connecting with the groups of heating tlues to supply gas thereto, separate gas conduits `supplying gas tothe end heating flucs whereby an excess ot heat maybe produced in the end heating fines, and air channels arranged under the hearth ot the colring chambers and connected to the groups otl heating flues to supply air thereto. .j

2. In a coke-oven of the kind described, coking chambers, heating chambers arranged laterally of the'coking chambers and each divided into a plurality ot flues, two of the llues ot each chamber being exhaust tlus and spaced apart and between twol adjacent groups of the other lines: a plurality of gas chambers connected tothe heating llues to supplygas, independently of each other, to separate groups of heating tlues, additional means for supplying gasto'the end heating flues in the end of each .chamber whereby an eXcess'of heat may be produced in the said into four groups of vertical heating flueis and two descending ilues for the escape of the burnt gases, each of said descending lues being arranged between two adjacent groups of vertical heating lues, a plurality of gas chambers arranged under the heating chambers, each of saidv gas chambers supplying with gas, a group ot" vertical heatingi'tlues, independently of the others, in a same heating chamber; two separate gas-supplying devices for the end lues of each heating chamber one for each end flue of each end chamber, a plurality of air channels under the hearth of each coking chamber, said channels being arranged in pairs in the axis of each otherand'each pair supplying with air two adjacent groups ot vertical heating flues in corresponding heating chambers, air galleries arranged laterally under the air chan` nels, at both ends of the oven, saidgalleries supplying air on one side ot the oven to the air channel corresponding to a rst group of vertical heating lues and on the other side of the oven, to the air channel corresponding to a second group of vertical heating tlues, adjacent to the first group, and so on, and collecting gallekries for the burntgases, said collecting galleries being situated between the lateral'air galleries anda central air gases, each of said descending fines being arranged between two adjacent groups of vertical heating lues, means for collecting and removing the burnt gases Jfrom the descending flues, means whereby the said ygroups of vertical heating ues are supplied with gas, independently of each other, air.

.ranged in such a manner that two adjacent groups of vertical heatiunfr flues in -a same eating chamber are supplied with air from" opposite endsof the oven,` air-galleries ar,

Lacasse ranged laterally at both ends of the oven,

said galleries communicating in alternance 15 structure of the oven can be recuberated and the loss of heat can be practically avoided.

In testimony whereof-I have aixed my signature in presence of twovwitnesses. v i EUGENE LECOCQ. Witnesses: JAQES BEBE EMIL VAN WANZEEL.
