useful improvement in Coke-Gvens, oi:-`-

ivhich the following is a speciiication.

This invention relates to/ structures 'for producingl colte in which. the coke ovens are long narrow chambers, .vertically arranged, with provisions at their upper parts for charging them 'with coal or material to be colred and provisions at their ends for dis* charging the coke. The structure of this invention includes a number of such coke ovens suitably spaced apart; vertical com bustion chambers, divided into a number of sections located, between the ovens and adjoining` the side Walls, the laterally adjoining sections between the Walls of' adjacent connected together. by suitable passages at their upper ends; `regenerator heaters loca beneath the ovens and divided into a. umher of sections, alternate regenerators being' heated by the products of combustion of the 'fuel passing from some of the combustion chambers, While the other regenerators, previously so heated, are imparting heat to air supplied to the other combustion chambers; gaseous fuel supply pipes and gas ports located at the lower part of 'the combustion chambers; means for alternately directing the gas to the ports of theA connected adjacent combustion chambers, whereby' the chambers alternately act as downtakes for the. products of combustion from the other chambers, to which they are connected, and means'adapted to supp'lyair to the chambers actingas down-takes. It also includes moans for allowing air to iioW alternately to the sections of adjacent regenl erators and to open the. other regenerators,

are passing, to Waste heat fines.

Fig. 8 is a general plan of the structure, diagrammatically showing the flow of the gas, air, etc.

The drawings illustratev a structure designed to suitably embody the novel features of this invention. The coke ovens are Along chambers Whose vertical dimensions greatly exceed their horizontal lateral dimensions. They are all alike but are alternately designated by 9 and 10 to facilitate description. Each is provided with a number of top openings ll through which the coal. to be coked is passed so as to uniformly lill vthe ovens. Their ends are closed by doors 12,- suitably luted, during the coking operation, andieach one has all upper opening 13 for the discharge of the volatile and gaseous constituents oit' the coal. Regenerators, of ordinary checker brick construction, are located beneath the ovens. Each regenerator is preferably divided into two parts the d'ividing walls of which are laterally centrally located relative to the ovens. Each part is divided into a suitable number' of sections that decrease in size from the ends of the ovens toward their centers .to'provide for uniform, distribution of air which is sup# plied to them from the outer ends of each series of sections. Four such sections are shown, indicated by 14, 15, and 17, each section having a separate air duct indicated respectively by 18, 19, 2O and 21. The regenerators, as units extending under the'4 ovens, arealternately .marked 2Q, 23,v on the operative illustration Fig. 8, ,which will be referred to hereafter. Occupying the spaces between the ovens 9 and '10 setsor" narrow vertical combustion chambers 24 and 25 separated by vertical walls 26. Those marked 24 adjoin and cover the side walls of ovens-9 and those marked 25 adjoin and cover the side walls of ovens 10. The outer ends of each set of`

air ducts

18, 19, and 21 open into a valve box 27, which is provided With a valve 28 adapted to close the air entrance to said box and also to close an outlet from the box to a waste heat flue 29 when the air entrance is; open. There is thus va :tree and unobstructed flow of air through all of the air ducts or passages to the separate regenerators, said passages being open through the valve boxes directly to the atmosphere at both sides of the structure. The waste heat iues 9.9 located at the ends of the structure connect with a stack 30, the draft of which acts to cause the proper How of the air to and the products of combustion from the'v structure. The flues 29 are provided with gates or dampers 31 to regulate the low of gases through the` Structure. At the upper end of each of the sections of the regenerators are ports 32 ex- 'tending in both directions and opening into the lower ends-ot a suitable number of the narron combustion chambers at the two sides ol' the oven above the regeperator.

A gas pipe 33\is located beneath each set of combustion chambers adjoining each of the side walls of the ovens, and from these `pipes ports 31 open into t-he chambers ad one of the chambers, to heat its..t adjoining oven, the other is acting as a down-take toimpart the heat of the products ot' eoi'nbusf tionto the side wall. of its adjoining oven.

`Means are provided 4for governing the How of gases. etc. through the, combustion chambers, shown as consisting of flat bricks 3S in the chambers 37 adapted to be set, by means of a suitable implement operated through `openings 39 extending tothe top of the structure, to more or less rover the port passages 36.

The gaspipes 33 are connected at their outer ends toa gas main 40, and each is provided with a cut-ofi' valve 41. To insure a uniform supply of gasto all `of the combustion chambers, particularly ivhen the coke ovens are of considerable length, it is proposed 'to provide each end of the structure with a gas main 'Ll-0 so as to supply gas to the two outerends ot' the pipes 33. To open the gas pipes to the atmosphere, when the gas is s h'ut cti', coclis or valves of a three- Way construction may be employed. Such valves are conventionally illustrated in the drawings, designating the air inlets through 'which fresh air will pass 'to the pipes 33 and to the lower parts of the combustion chan'ibers 24 and through the ports 34. This supply of air to the lower parts of the combustion chambers takes place when the chambers are acting as downtakes for their adjoining' chambers and the productsof combustion are passing to the regenerators. The object and effect ot' this supplyv of cool air is to pre/vent over-heat.- ingl ol' the part ot' the chambers where the gas enters to such an extent as would cause carbon deposition from vthe fresh iniowing gas, when the cluimbers are acting again as combustion chan'ibers, and also to keep-said ports clear and free b v blowing therefrom any deposit that would tend to choke them.

The alternating ioiv of air, gas and the products of combustion is clearly illustrated in Fig. It being assumed that the coke ovens are infull operation, air is en .tering the regenerators 22, through the openings in the valve boxes at thsune time that gas from the mains iioving to the. combustion chambers adjoining the colre ovens that are above the regenerators 22. The 'products ot' combustion from the chambers adjoining the coke ovens above the alternateregenerators 23 are at the saine time passing through and heating said regenerators, and therefrom flow by the iiues 29, to the stack 30, the valves in the boxes 2T then heilig set to close the fresh air openings. about thirty niiiuites, air is, by the threeivay cocks l1, entering the coinluistion chambers adjoining the ovens above the regenerators 23 as and for the purpose previously described. At theI end (it the suitable heating period7 the valves and 41 arr` nianipulated to reverse the flow through the regenerators1 the air then being caused to flow through the heated regenerators 23 and gas to the combustion chambers adjoining the ovens above said regenerators; the products o t combustion then fioa' through the regenerators 22 and raise their temperature to a degree sufficient to adequately heat the in- `ioiving air when the operation is again reversed.

During this time,-\vhich may be.

It ivill' be observed that by providing each section of the regenerators with an individual air passage'thej'" will receive amounts leI ties of the sections as they recede .from the air inlets.' x It will also be observed that by dividingthe eolie ovens heating means into a number of narrow combustion chambers the supply of gas and air thereto is under pe .iectvcontrol and thereby the consumption of fuelffmay be reduced to a minimum and the ovens also uniformly heated throughout their length.
