18 Claims.
My invention relates to coking retort ovens and vparticularly to coke ovens of' the horizontal type in which the iniiow of combustible media and the outiiow of products of combustion occur inthe same heating wall simultaneously.
It is an object of thepresent invention to provide a coke-oven battery that is so arranged that the upper structure comprising the coking chambers and heating walls is supported by a regenerator structure of such construction that its walls l are suitably located with respect to the distribution of the loads to be supported and the regenerator walls may be of relatively great strength. A further object of my invention is to provide a regenerator structure beneath the coking chambers and heating walls of a horizontal coke-oven battery in which expansion joints are so located that they are not traversed by any of the ducts for conveying gas and air to the flame nues of the heating walls or for conveying waste gases therefrom. A further object of my invention is to provide a regenerator structure of such nature that the expansion joints therethrough may divide theregenerator structure into units that are self-contained with respect to the transmission of combustible media to, and the transmission of waste` gases from, the flame fiues of the heating wall with which such units co-operate.
A further object of my invention is to provide an arrangement comprising a series of regenerators for-each heating wall forconnection to certain of the flame ilues thereof in such manner that an air regenerator is always interposed between a gas regenerator and a waste-gas regenerator of the series whereby counterllow between the latter regenerators may be avoidedin either,
direction of.flow of gases through the coke oven structure..
A still further object of my invention is to provide a unitary reversible mechanism for simultaneously conducting combustible media td 'a coke-oven structure and conveying waste gases therefrom.
The coke-oven battery of the present invention I comprises a series ofv alternatelyfdiSPOsed coking chambers and heating walls. The flame nues of each heating wall are connected in pairs for operation in series whereby one flue operates as a return ue for products of combustion from the other ilue of the pair. A series of regenerators is provided for each heating wall and the regenerators are divided into groups of one large and two small regenerators. Each group conducts combustible media to, or conveys waste gases lthe heating system of one heating wall'of the which support the upper structure of the battery.
Between each pair of closely adjacent side walls beneath a coking chamber is an expansion joint that extends from the bottom of the coking chamber vertically downward to the bottom of the supporting structure. The regenerators of the series beneath each heating wall are connected to a series ofducts located beneath the regenerators and between the side walls of the latter. Each of these ducts is connected tov certain'of the regenerators. l y
This arrangement of the regenerator structure and the expansion joints insures that the latter are not traversed by any of the ducts for connect- `ing the exterior of the coke-oven battery to the regenerators or for connecting the regenerators to the corresponding name flues.- This arrangement tends to minimize leakage which is caused when expansion joints intersect ducts for carrying combustible media or waste gases, as is frequently necessary in the construction `oi! coke ovens in accordance with the prior art.
My invention wlll be described in connection with the accompanying drawings, in which Figure 1 is a view in transverse vertical section, 9.0 taken on line I-I of Fig. 2, through the heating wall of a portion o! a coke-oven battery constructedin accordance with my invention;
Fig. 2 lisa view in longitudinal section of a portion of the battery taken on line II--II of Fig. 1; 95 Fig. 3 is a composite horizontal sectional view,
Fig. 4 is a diagrammatic view in perspective of coke-oven battery; A
Fig. 5 i's a side elevational view of a reversing box for controlling the simultaneous admission of combustible media to and the withdrawal of combustible gases from a plurality'of ducts, together with certain associated parts; .a
Fig. 6 is a top plan view of the reversing ybox of Fig. 5, the cover being. removed; and f Fig. 'I is a front elevational view of a portion no transversely of the battery and are separated by a horizontal brickwork 7 from a regenerator structure 8, which rests upon the foundation 2.
The coking chambers 5 are provided with the usual, charging openings 10, extending through the top 4. A gas main 11. supplies producer gasv through a series of reversing boxes 12, one of which appears in Fig. 1. A waste gas main 13 conducts gases of combustion from the battery to the usual stack.
As best shown in Fig. 1., each heating wall 6 is provided with a series of vertical iiame nues 15 that are connected at their tops in pairs whereby one ilue operates as a return iiue for conveying products of combustion from the ue to which it is connected. The number of ame flues in each wall maybe as desired, depending upon the length of the heating walls and the coking chambers of the battery.
'Ihe regenerator structure 8, which is located beneath the horizontal brickwork 7 and which supports the coking chambers 5 and the heating walls 6 comprises regenerator units equal in number to that of the heating walls, each unit being substantially co-extensive horizontally with the heating wall. Each regenerator unit comprises two side walls 16 that are respectively located substantially directly beneath the adjacent coking chambers, the side walls of adjacent regenerator units beingseparated by an expansion joint 17 that extends from substantially the center of the coking chamber vertically downward to the bottom of the supporting structure.
Each regenerator unit is divided into a number of compartments or regenerators by means of relatively thick walls 18 and relatively thin walls 19. The regenerators into which each unit is divided are of two sizes, the larger regenerators being substantially double the capacity of the smaller regenerators. Each small regenerator 20 is connected by an inclined duct 21 to one of the ame flues 15 while each large regenerator 22 is connected by similar inclined ducts 21 to two adjacent flame flues which, however, are members of different pairs of flame flues.
As shown in Fig. 1 and also in Fig. 4, the regenerators are in groups of one large regenerator and one small regenerator on opposite sides of the large regenerator for supplying combustible media to two flame ues of adjacent pairs or for conveying products of combustion from the same flame flues when the direction of flow is reversed. v
Beneatheach regenerator unit is a series of four ducts 24, 25, 26 and 27, that are arranged in two superposed pairs. As shown in Fig. 4, eachduct 24 is connected by verticalducts 28 to alternate large regenerators 22 and the duct 26 is similarly connected to the other large regenerators 22. The duct 25 is connected to alternate pairs of small regenerators 20 and the duct vgas valves 34 and 35.
vided with a nozzle 30 for the entrance of rich gas, it being noted in Fig. 3 that the nozzles are disposed on opposite sides of adjacent pairs of name flues 15.
Reference may now be had to Figs. 5, 6 and 7, in which a reversing box 12 and certain of the connected parts are shown in enlarged detail. The box 12 is connected to the gas main l1 by means of a bifurcated pipe 31, the branches of which are respectively connected to `passageways 32 and 33 within the maincasting of the reversing box 12 and that are respectively controlled by The passageway 32 is connected to a ltubular extension 36 that is connected to one of the upper ducts, for example, the duct 24, that extends under the regenerators, as previously described. The passageway 33 is similarly connected to a downwardly curved tubular extension 37 that is connected to the duct 26.
The reversing box l2 is connected to the waste gas main 13 by means of a vertical extension 38 that is connected to a horizontal passageway 39 in the upperA portion of the reversing box. The passageway 39 is connected through a valve 41 to the extension 36 and the duct 24. The passageway 39 is connected also through a valve 42 to the extension 37- and duct 26.
Each of the passageways 32 and 33 is provided at its outer end beyond the valves 33 and 34 with a pivoted damper 43, which is opened when the corresponding passageway is suppliedwith air and which is closed when the corresponding passageway lis supplied with gas.
In the operation of the reversing box 12 shown in Figs. 5, 6 and 7, and which is typical of all of the reversing boxes for the battery, it may be assumed that producer gas is being used as a fuel and that the manually-operated v alve 44 is open. It may be assumed that the valve 34 is open and the valve 35 is closed whereby gas will flow through the passageway 32 and extension 3 6 into duct 24. Under these conditions, the waste gas valve 41 is closed and the waste gas valve 42 is open to permit waste gases from the duct 26 to flow outwardly through the extension 37 and passageway 39 through extension 38 to the waste gas main 13.
When it is desired to reverse the flow of gases in the battery, the usual reversing mechanism operates and the open valves 42 and 34 are closed and the closed valves 41 and 35 are opened, whereupon gas is supplied through the passageway 33 and extension 37 to the duct 26 and waste gases flow from the duct 24 through extension 36 closed and vthe dampers 43 will be' alternately opened to supply air to the one or the other of the passageways in accordance with the direction of flow of gases in the battery. The operation is otherwise as described for use as a gas box.
The operation of the battery may be described with particular reference to Fig. 4, in which the directions 0f flow through the various parts of the heating system for a portion of one heating wall are indicated by arrows. It has been assumed that gas is supplied-to the gas duct 24, air is supplied to the air duct 25 and waste gases are being withdrawn through the ducts 26 and 27.
The duct 24 is connected to alternate large regenerators 22, which supply one flame flue of each of two adjacent pairs. The air regenerators to which the duct 25 is connected are ,connected to one flame flue of each pair. The gases burn" upwardly in one member of each pair of flame flues and the products of combustion pass downwardly through the other flame flue and through the small regenerator and the large regenerator that are connected thereto.
It will be noted that a .group of regenerators 4consisting of two small regenerators and one .large one supply combustible media to two pairs of flame flues while a similar pair of regenerators conduct waste gases from a similar number of pairs of flame fiues.
It may be noted, also, as indicated by appropriate legends G, A and W in full lines, denoting regenerators adapted for operation for concurrent flow of gas, air and waste gases, respectively, in Fig. 4, that the gas regenerators G operable for inflow of gas are always separated from the other regenerators operable concurrently forv outflow as waste gas regenerators W by an air regenerator A operable concurrently for inflow of air.
products carried by the several regenerators andr the manner in which they are adapted for operation of such reversal are indicated by corresponding legends in dotted lines. It will be understood that the direction of flow through the various parts of the system will be opposite that indicated by the arrows.
The arrangement of the regenerators in series beneath each heating wall and the location of their sides walls beneath the coking chambers is of particular advantage in that the side walls are in position to directly support the loads of the coking chambers when the latter are filled. The arrangement of the regenerators for each heating wall in a series beneath it permits the use of partition walls which impart stability to the side walls which might otherwise be relatively long and comparatively narrow, as in certain structures of the prior art.
The provision ofregenerator units for each heating wall enables the provision of expansion joints between the units whereby the expansion joints are not traversed by any of the inclined ducts for conveying gas, air or wastev gases. It
will be appreciated that such leakage as may voccur through the sidewalls of ducts is mini- Aing walls therefor having flame flues, a supporting structure for said coking chambers and heatl ing walls comprising a series of regenerators beneath each heating wall and communicably connected to said flame flues and having side walls extending beneath said coking chambers and pairs in series, certainof said regenerators being transversely of the battery, and expansion joints in said side walls and extending from the bottoms of said coking chambers to the bottom of the supporting structure.
