f Y -coKING ovEN AND OTHER EURNACE Application mea Navemterir, waaserial No. 148,859." A

, 'Myinvention `consists in new and useful improvements in by-product coke ovensr and other furnaces infwhich the material being heatedand the heating medium/are separated by'a wall or lining throughwhich the heatvpasses to perform its function. lMy invention is perhaps most conveniently described as it is applied tolfthe by-product' coke oven, although I donot limit myself to this application.

the flow of heat through the wall or lining by means of a large wall surface area, f

IIeretofore,` the sideY heating walls -of all lthe different types of by-product ovens have been constructed of vbricks which, While dif- Vfering widely in size and shape, have always i hadstraight plane surfaces on the sides that collectively form theoven lining, andthe -fiue linings. Hence, all of these oven lin# ings 4-have formerly presented -a plane flat sur-` face to the coalfcharge VThe vertical dimen- Vsion of the heating surface, was therefore a straight line drawn from top to bottom of 25,-the heating wall, while the horizontal dimension was a straight line drawn from the pusher end to the discharge end of the heating wall., l

As applied to coke'. ovens, my invention 'ccmprises an oven lining which, for anyand `all sizes of oven chambers will present a greater area of heating surface either to the coal charge or to the heating medium or both, mthan that provided for by a straight flat V*plane surface lining of the type hereinbefore referred to. v

Withthe above and other objects in view which will appear-fas the description proceeds, 40, `my invention consistsin the novel features "wherein set forth, illustrated in the accompanying drawing and more particularly pointed out in the appended claims.

Referring to the drawings, in which nu- .4.5` merals of like character designate similar parts throughout the several views,

6` represents each of a aseries of heating` chambers beneath said cokingl ovens, which f lmay be of any desired typefin communication with the iues 4c and 5 `by means offp'assages?. y

It will be seen that an ovenliningj constructed in the above Inannerisfin harmony and agreement with-- the lrequisites -of the Y pushing operation, in addition to the increased heating-area. There are no obstruc-v tions inthis lining to the forward movement of the coke, and since the outline of the coke'A charge-is taken fromth'e profile of thevoven walls, it follows that the coke will vrbefree ,tow move forward through this ltype of oven chamber, just as in the casey with the plane surfaceoven chamber. In ,thisconnectionf the fact` that most.y of the so-called cokingc,

coals and practically all mixtures used vin c mass intact and directing its travel, but offering no great resistancewhen the oven is properly tapered, tothe passageof the coke Y fromthe oven. yFor this reason, ,the large heating surface offeredKY by this 5 new y, oven",` lining Vwill not be detriment al, from the standf point of discharging l,the ovem but on; the

vthe moving `mass"0f coke, holding thefcoke p aia ters VPatent is: Y 1. A horizontal cokingv oven including-- means forfopening lsaid oven at both'l of longitudinalextremities said oven being prp vided with heating walls having horizontally` contrary, will withcertain cokes, be beneficial inasmuch as Vthe projections of this lining willtend to hold the coke mass, so that there will be less side wall friction to overcome than is the case with a plane surface wall.

An apparatus` constructedin accordance vwith my. invention", obviously provides kthe oven Walls with a larger surface forA either theabsorption of heat Vfrom the burning ue gases, or for the distribution of li'eat to the coal or both, than that provided by aplane surface lining of corresponding height` and breadth. The advantage of the larger heating surface, is so far as the'radiationrand conduction of heat are concerned, is evident.

A further advantage `of this construction resides in the fact that the increase o'fheatl ing `surface which is given by this new lining will cause a corresponding increase 1n ,the

area ofthe fusion zone formed by the coking proces`s,' inasmuch as'the'fusion zone starts at 'the oven wall and remains practically parallel to the same as they cokingoperation proceeds inward through the coal mass. This f 2means that both the area of andthe Aprofile of the fusionrzone are functions of the exposed area of the heatingiwall. 'Illie increase in area and the 'change in profile or" outline of the fusion zone obtained by virtue 'of my improved wall heating surface, will tendto. distribute a comparatively large amount of the sensible heat of thegases evolved to.l the coal mass and byso doing, speed up thecokin'g op-` eration.

From the foregoing, it is believed that imy' invention may be clearly' understood by 'those skilled in the,` art without' further descriptionj, it beingborne in mind that numerous dchanges may be made in the' details of coni struction without departing from the 'spirit of the invention 'as vslet forth in tlie' following claims; I
