ARTHUR OWEN JONES, OF WHITLEY BAY, ENGLAND.

COKE-OVEN.

' r' i I Specification of Letters Patent. Patented NOV. 14, 1911.

Application filed April 26, 1911. Serial No. 628,388.'

Toall whom it may concemf Be it known that I, ARTHUR OWEN J ONES,

a subject of the King of Great Britain, re-

siding at Whitley Bay, in the county of Northumberland England, have invented certain new and useful Improvements in Coke-Ovens, and of. which the following is a specification.

Coke ovens in which the coal is fed in at an open top and in which the coked product is discharged through the base, are already known and are commonly termed vertical coke ovens. Now the present invention refers to coke ovens of this type, and in such ovens it has'already been proposed to provide horizontal superposed heating flues independent one of the other and all discharging the products of combustion into a common vertical out-let flue in the structure adjacent to the front wall of the oven, while the inlet end of each horizontal flue has extended to the face of the structure andhas been there supplied with gas and air, and I have before proposed to supply the air to such horizontal flues by a-common air sup ply passage. horizontal flues, they have, been caused to pass within and along one side wall of an oven, around the end of the oven and have returned along and within the other side wall of the oven to the common vertical outletflue at the front end of the oven.

Now the object of the present invention is to construct the horizontal heating flues of such ovens entirely in the side walls thereof, so that they do not pass around the ends of the ovens, and thereby the coking action takes place entirely from the sides of theoven and not from the ends thereof. According to this invention therefore I locate the common vertical outlet flue or flues for each oven not immediately at the ends of the said ovens but between two adjacent ovens. One end of each'horizontal flue extends as heretofore to the face of the structure where it communicates with a vertical air flue common to all the horizontal flues, and where also it is supplied with gas. The flue, from its gas admittance end, extends in one side wall adjacent to one oven, and then passes by a cross passage and returns in the same sidewall adjacent to the next oven, and at its return end it communicates with a vertical outlet flue (common to all the. horizontal flues) which is constructed in the same side Wall. The horizontal flues may In the construction of such be arranged in such a manner that the gas 1s admitted to that horizontal arm of one of the flues extending in the wall adjacent to the oven on one slde, while in the next horizontal flue the gas is admitted to that horizontal arm of that flue which is in prox imity to the next oven, and soon, considering a series of said superposed heating flues,

and by arranging thus, the horizontal arm of one flue, into which the as is admitted directly, alternates with the orizontal arms of the flues through which the products of combustion pass to the common exit. Or

the flues may be arranged in the wall between two ovens, so that the horizontal arm into which the gas is admitted is in the cate by a vertical passage with a lower flue which is vertically beneath the said admittance flue, and through this lower flue the products of combustion return. By this arrangement the requisite quantity of heat is supplied to the charge near the base and at the thickest part thereof, and by the return or outlet arm being located immediately below that inlet arm which is level with or justabove the top of the sole plate, the heat is conserved in the said inlet arm.

In order that the invention may be more readily understood, reference is made to the accompanying drawings whereon Figure 1 is a vertical transverse section on the line A B of Fig. 2, and Fig. 2 is a horizontal section on the line C D of Fig. 1, showing ovens provided with flues according to this invention, the left hand portion of the figure'showing the arm of the flue connected with the gas supply (hereafter referred to as the inlet arm) and the arm of the flue connected with the main exit flue (hereafter referred to as the outlet arm) arranged in the same horizontal planes, the right hand portion of the figures showing the inlet and outlet arms arranged in a vertical plane, two series of such flues being arranged in one dividingor oven side wall and adapted each series to heat one side of one oven or coking chamber. Fig. 3 is a vertical longitudinal sect1on through the flues shown at the right of Fig. 1, the section tending from the forward and rearward faces of the oven structure to the center of the dividing or side walls. Fig. 5 is a vertical longitudinal section of a modified arrangement of flues shown in Fig. 3, in which. the flues extend from the forward and rearward faces of the oven structure to the center of the dividing or side wall between two ovens. Fig. 6 is avertical transverse section showing an arrangement of flues similar to that shown at the right of Fig. 1 but in which one series of flues arranged in a vertical plane is employed to heat the adjacent sides of two ovens, and Fig. 7 is a diagram to illustrate the effect of heating and coking chambers by means of side flues only and Fig. 8 is a diagram illustrating the effect in known ovens where the. flues also extend around the ends of the ovens.

' In the accompanying drawings the oven structures comprise coking chambers 1 having gas outlets 1 (see Figs. 1 and 6), front and rear walls 2 and 3 respectively, and side or dividing walls 4. Formed in the front wall 2 of the structure and immediately at the-end ofthe dividing walls 4 as shown in Fig. 2, is a common vertical outlet flue 5, and a common vertical air inletflue 6, with which latter flue communicates, by means of a passage 7 controlled'by a valve 8, each inlet arm. 9of the heating flues. The arms 9, according to the construction shown at the left of Figs. 1 and 2, proceed rearwardly along the side of one coking chamber to the end of the said coking chambers 1, and are each connected by a cross passage 10 formed in the dividingwalls l with the outlet arm 9, which extends along the opposite side of an adjacent coking chamber, and in turn communicates at its forward end with the outlet flue 5 by means of a passage 11 controlled by a valve 12.

The inlet arm 9 of each heating flue is fitted at its forward end with a gas burner 13, and is connected as aforesaid with the air inlet flue 6, the forward end of each outlet arm being connected with the outlet flue 5, and the. connection of the said outlet and inlet arms with their respective flues is such that considering one side of the coking chamber, the inlet arms 9 of the flues alternate in vertical series with the outlet arms 9 of the next upper or lower adjacent flue. This arrangement of flues is clearly shown at the left of Fig. 1. As shown at the right of Figs. 1 and 2 and at Fig. 3, the heating flues instead of extending along one sid e of a coking chamber-and returning along the side of the adjacent coking chamber as in the construction shown at the left-of Fig. 1, are arranged so that each side .of each coking chamber is heated by an independent series of heating flues, and according to this arrangement the inlet arm 9 of the heating flue is arranged immediately above or below, as the case may be, the outlet arm 9? of its flue, thesaid arms being connected at their rearward ends by a short vertical passage 10 in the side or dividing walls 4.

A single series of heating flues such as lastly described may be employed to heat the adjacent sides of two adjacent coking chambers, as illustrated in Fig. 6, in which case the thickness of the dividing wall between the coking chambers 1 is materially decreased.

4 Obviously, the heating flues may extend from the front wall to about the center of the structure and also another series extends from the rearward wall to about the center of the structure, so that with one set of flues the inlet arms will open on the front of the structure while the outlet arms will commuarms communicating with a common ver-."

tical outlet flue in'the rearward wall of the structure, a central partition in the dividing side wall of an oven separating these two forward and rearward sets of flues. Such a construct-ion is illustrated at Fig. 4: in sectional plan with these two sets of forward and rearward flues respectively constructed on similar lines to those shown on the left hand side. of Fig. 2, the two adjacent passages 10 in a side wall being divided the one from the other by the partition 14, and the other features of this construction are marked with letters corresponding to the left hand side of Fig. 2 and will therefore be readily understood.

At Fig. 5 in vertical section is shown an arrangement of the flues in vertical series similar to that illustrated and already described at the right handside of Fig. 2, there being at Fig. 5 two sets of these flues opening on to the rearward and forward walls of the oven structuredivided by a partition 14. 1

At the base of the oven as shown at Fig. 1 I arrange the lowermost heating flue so that its inlet arm 15 is level with or just above the top of the sole plate, while its outlet arm 16 is beneath it so that the communicating passage between the inlet arm the central plane.

I would therefore explain that it is unnecessary that the flues should do so, because shown at Fig. 8) (which it does not in the.

present invention), then coking coeds from the ends as indicated bythe small dotted arrows marked c, which in fact forms another plane of cleavage as shown. by dotted lines marked 03 extending transversely of With the arrangement according to the present invention as shown in Fig 7, there is less liabilityto form small coke than is the case whenlthe coking. chamhere are heated from the ends as shown in With the heating flues 9, 9 arranged as has been described at Figs. 1 to 6, alter- Dating in a vertical plane as regards the directicn in which the heat travels, the amount each side is substantially e ual, while with the arran ement dealt with in thisspecification, the ingth of the flues is lessened so that the travel of the heating mediu'ntis correspondingly shorter than if the said flues heating flues, the'ends thereof extending ad jacent to theexterior of the end wall of the structure, one end of each side wall having a Vertical air inlet flue with which flue one arm of each U-shaped flue communicates, and a vertical outlet flue with which the other arm of each U-shaped flue communicates and through which the products of combustion from said heating flues pass, means in connection with each U-shaped heating flue to admit heating gas thereto, and means for controlling the passage of products of combustion through one or more of the U-shaped flues independent-of the other U-shaped flues.
