4 Claims. (Cl. 202-268) This invention relates to coke ovens of the kind in which regenerators are provided for the alternate heating of gas and air or air alone and which regenerators are arranged below the coking chambers, extend longitudinally of these chambers, and as shown, for example, in United States Patent 1,947,500 of February 20, 1934, are divided by partition walls extending longitudinally of the battery into regenerator compartments.

In designing such partition walls, it is necessary to provide for expansion joints therein which permit longitudinal expansion of the coke oven battery and at the same time have the partition walls of gas tight construction, so that leakage of gas from one regenerator compartment into the next compartment will not take place.

This invention relates to the construction and design of these partition walls to provide effective expansion joints therein, permitting longitudinal expansion of the battery while also providing partition wall structures which effectively prevent leakage of gas from one regenerator compartment to another, and moreover, serve to buttress or strengthen the cross-wise extending walls disposed beneath the coking chambers parallel thereto and defining the sides of the regenerators.

In the accompanying drawings forming a part of this specification and showing for purposes of exemplication a preferred form of this invention, without limiting the claimed invention to this illustrative instance:

Fig. 1 is a cross-wise vertical section of a coke oven battery taken longitudinally through a heating wall and the regenerator compartments therebeneath; l

Fig. 2 is a fragmentary enlarged horizontal section through two contiguous partition walls embodying the improvement of the present invention, the section being taken on line 2-2 of Fig. 4 and extending through the even numbered courses of brick forming the partition walls;

Fig'. 3 is a fragmentary enlarged horizontal section through two contiguous partition walls embodying the improvement of the present inpassing through theline 4-4 of Figs. 1, 2 and 3,

showing the partition walls, viewed in the direction indicated by the arrows, in elevation and illustrating the staggered arrangement of joints in courses of brick forming the partition walls;

Fig. 5 is a fragmentary section through a partition wall, taken in a vertical plane passing through the line 5--5 of Fig. 3, and shows the tongue and groove joints between the brick of contiguous courses constituting the partition wall;

and

Fig. 6 is a fragmentary sectional view somewhat diagrammatic in character and on a smaller scale than Fig. 3, the section being taken on line 3-3 oi' Fig. 4.

Referring to the drawing, there is shown in Figs. 1 and 2 a coke oven battery of the type more fully described in the aforementioned United States Letters Patent 1,947,500, involving a series of alternate horizontal coking chambers and heating walls I2 therefor, arranged side by side in a row. Regenerators situated below the coking chambers'are dened by cross-wise extending walls I3 and longitudinally extending partition walls I 4 hereinafter more fully described. As shown in Fig. 4, the partition walls I4 are constituted of courses of brick I0 referred to herein as even numbered courses and alternate courses of brick II referred to herein as odd numbered courses. In the embodiment of the invention shown on the drawings, three partition walls are provided, defining four regenerator compartments which are arranged so that cross-wise of the battery alternate regenerators feed airor gas to the heating ues while products of combustion are discharged through the remaining regenerators. As this invention is particularly concerned with the design and structure of the partition Walls I4, and as the other features of the construction and operation of the battery disclosed in the accompanying drawings are fully described in the aforementioned patent, it is believed unnecessary to describe such other features in greater detail.

As shown in Figs. 2 to 5, each cross-wise extending wall is built up of silica brick I5. Each partition wall I 4, in accordance with this invention, is constructed and designed to provide expansion joints permiting longitudinal expansion of the oven battery, while'at the same time producing a gas tight barrier between the regenerator compartments at the opposite sides thereof, and reinforcing or buttressing the cross-Wise extending walls I3. In the particular embodiment of the invention shown on the drawings each partition wall is built up of brick shapes disposed in courses; Fig. 2 representing a section through the bricks constituting the even numbered courses, while Fig. 3 shows the brick shapes in the odd numbered courses.

The even numbered courses of brick of each partition wall, as appears from Fig. 2, comprise the brick 5 having a projecting portion I8 and a groove for receiving a tongue of brick I1. One end of brick I1 has a tongue for reception by a groove in one end of brick I8. The latter brick is held in place by an angle brick I9 having a tongue which enters a groove in brick 20. One

` end of brick I8 is spaced from the end of 'brick reach its full expansion when heated without completely filling these spaces.

Bricks 5, I1, I8 and I9 define one side of the partition wall. The opposite side of this wall is defined by the bricks 23, 24 and 25 which may be of the shape shown in the drawings. Bricks 23 and 24 are joined by tongue and groove connections and end 26 of brick 24 is spaced from a filler brick 21 to form the expansion joint space 2I'. Brick 2 1 has tongue and groove connections with bricks I1 and 25. Projecting portion of brick 25 1 extends over the end portion of brick 24 dening the expansion joint space 2 I C, thus enclosing this space.

Referring to Fig. 3, the left side ofeach partition wall (viewing this figure) is constituted of bricks 3I, 32 and 33 of the shape shown; brick 3I being bonded to brick 32 by a tongue and groove joint. Brick 33 has a projecting portion 34 which extends over the end portion of brick 32 and covers the expansion joint space 2I 4defined by the end of brick 32 and filler brick 35. The right side of the partition wall is constituted' of bricks 38, 31, 38 and 39; brick 31 being bonded to brick 38 by a tongue and groove joint and brick 38 being bonded to brick 39 and filler brick 35 by tongue and groove joints as shown on the drawings. Brick 38 has a projection 40 which extends over the end portion of brick 31, which with ller brick 4I, defines expansion joint space 2I'. Brick 39 has a projection 42 which abuts the face of brick 38.

l It will be noted from Fig. 4 that joints 43 between the bricks 23, 24 in the evennumbered courses are staggered with respect to the joints 44 between the bricks 31, 38 of the odd numbered courses. A sImilar arrangement of staggered joints results between bricks I1, I8 of the even numbered courses on the one hand and those between bricks 3|, 32 of the odd numbered courses on the other. `It is noted the expansion joints 2 I 2 I formed in laying the several courses of brick constituting the partition wall are aligned. As appears from Fig. 5, the brick of contiguous courses are bonded together by tongue and groove joints 58, i. e., bricks I8 and 24 have tongues on their bases which fit in grooves in the top surfaces of bricks 32 and 31 respectively, and the other bricks of each even numbered course are provided with tongues on their bases which nt in complemental vgrooves in the top surfaces of the bricks of the underlying odd numbered courses.

The bricks hereinabove referred to may be of silica or other high heat resisting refractory ma- 'terial suitable for the construction of the rewiththe exception of the contacting surfaces between bricks I8 and I9; I8 and 23; I8 and 24; I1 and 24 and 24 and 25 (Fig. 2) and between bricks 32 and 33; 3 2 and 38; 32 and 31; 3I and 31 and 31 and 40 (Fig. 3) during the laying of the brick to `form the walls, are bonded by a suitable fireclay mortar. tween the brick 'enumerated in the preceding sentence are laid dry, i. e., no mortar is intro.- duced therebetween. In effect this results in the production of partition walls each constituted of two substantially monolithic portions having surfaces thereof lying in a vertical plane extending the full height of the regenerator, one-of which monolithic portions is made up of bricks 23, 24 (Fig. 2) and 31,738, 39 (Fig. 3) having one end bonded with the wall shown at the top of Figs. 2 and 3, and the other end defining the expansion joint space 2I'; and the other of which monolithic portions is constituted of bricks 5, I1, I8 (Fig. 2) and 3I, 32 (Fig. 3) having one end bonded with the wall shown at the base of Figs. 2 and 3 and the other end defining the expansion joint space 2I.

With reference to each cross-Wise extending Wall I3, it will be noted that at a plurality of spacedpoints at opposite sides thereof there are disposed the monolithic portions constituted of bricks 23, 24 (Fig. 2) and 31, 38, 39 (Fig. 3) on one side, and bricks I1, I8 (Fig. 2) and 3I, 32 (Fig. 3) on the other side, the monolithic portions of one wall being disposed in surface contact with those of a contiguous Wall defining the regenerator compartments to provide the partition walls having expansion joints 2l, 2|' therein which reinforceor buttress the cross-wise extending wall I3. 'I'he buttressing effect of the monolithic partition wall sections will be more evident froii Fig. 6 wherein reference character A designates he partition lwall sections constituted of bricks I1, I8, 3I and 32, and B designates the sections constituted of bricks 23, 24, 31, 38 and 39. It will be observed that the monolithic partition wall sections A and B constitute series of buttresses or ribs extending laterally from each side of each crosswise extending wall I3, thereby strengthening the walls I3; each partition Wall section at'its free end forms expansion joint 2l or 2I permitting the walls I3 to move toward and away from each other upon contraction and expansion of the oven.

In the structure shown on the drawings, before leakage of gas from one regenerator compartment to another can take place through the expansion joints, it is necessary for the gas to travel through the tortuous and extended pathv corresponding to the contacting surfaces. between bricks I9, 28; I8, 23; I8, 24 and 24, 25, as well as through the two expansion joints 2| and 2|', in the case of the even numbered courses, the path through the odd numbered courses being of substantially the same extent and configuration, as is evident from Fig. 3. To further minimize leakage of gas, one or Vmore openings 60 may be formed between the contacting surfaces of bricksA I8 and 24 and 32 and 31 or atany desired point in the contacting plane 6I between the monolithic portions constituting each partition wall I4. These openings are packed with dry comminuted silica, providing a barrier for-fiow of gas therethrough. In practice it has been found that with the construction and design shown on the drawings, substantially no leakage of gas from one regenerator compartment into a .contiguous compartment takes place.

The contacting surfaces be land bonded thereto, one end It will be noted that this invention provides a brick-work partition wall construction for a coke oven battery which permits longitudinal expansion of the battery while at the same timminimizing, ii.' not completely preventing, leakage of gas from one regenerator compartment to another, and which partition walls reinforce or buttress the cross-wise extending regenerator walls.

It will be understood that this invention is not limited to the exact details of construction shown or described, for obvious modications will occur to a person skilled in the art.
