A, CORPORATION OF DELAWARE '1 romance WALL k a nomiilnedmem er 3,1927. Serial in. 237,400. r
This invention relates to furnace walls, and more particularly to? air-cooled walls and bricks therefor.
It is one of the primary purposes of this invention to prevent falling-in, bowing, crackin and spallin of refractory walls.
Flore specifica l it is an obJect of the inwall construction wherein the blocks, while constituting a substantially gas-tight refrac-Q tory wall, are yet individually capable, of
compensating for expansion and contraction in the wall resulting from variations in tem- 5 perature.
A further object of the invention is the provision of bricks for such a wall structure which, while admitting of an ample circulation of air, are nevertheless simple and rug ged in contour and proportions, and, conse quently, easily and cheaply manufactured and not readily broken either in handling or while in service.
How these advantages, and otherswhlch are incident to the invention or will occur to" those skilled in the art, are obtained, will be evident from the following description of thepresent preferred embodiment of the invention, reference being had to the accompanying drawings, wherein:
Fig. 1 is an elevational view of a portion of a furnace wall illustrating-an embodiment ofmy invention;
Fig. 2 is a vertical section taken on the line 2-2 of Fig. 1;
Fig. 3 is a horizontal sectiontaken on the line 3-3 of Fig. 1;
Fig. 4 is a similar section on the line 4-4 of Fig. 1;
Figs, 5 and 6 are perspective views of the header and filler blocks, respectively, em ployed in the wall; I l r Figs. 7 and 8 are similar views showing-a modified form of header and filler block, respectively, which may be used in a modified form of the wall;
Fig. 9 is a fragmentary elevation of a wall embodying the blocks of Figs. 7 and 8;
Fig. 10 is a section on the line 10-10 of Fig. 9, and l f. Fig, 11 is a section on the.line -11 11 of ller blocks 4, laid in horizontal courses or rows, there being a pair of courses of header blocks 3 between ad]acent courses of the filler blocks 4, the blocks of one course of each ;such pair being reversed or turned upside relation to the other course of the down with pair. p
This construction, however, with its details, will be better understood from an inspection of Figs. 5 and 6, showing the bricks in perspective. y p
The header blocks 3 each have a vertical grooveior' recess 5 at each end, adapted, when ;gortion composed of header blocks 3 and vention to provide an improved air-cooled ,in-{zlpoejition' in the wall, to provide vertical aing ch nn els 6 (see Figs. 3 and 4) The por- .tion of the brick, back of the grooves 5, is adapted to be bonded or tied into wall structure 2 and to fit snugl at its ends 9g'against adjacent header bloc s or bricks "i(seei;,Figs. 2 to 4), while theforward por- .ti'on of the brick, from the grooves 5 to the exposed face 8, is somewhat shorter between its ends 10, so that, when the bricks are in One horizontal face 'of the brick 3 is flat, so
the outer position, as in Figs, 4, a space 11 is left bef tween gadjacent bricks to permit horizontal that, by reversal, two horizontal courses of them may be juxtaposed, as shown in Fig. 2, while the opposite face has a step or recess "12 adjacent the front face 8, such step being of sufficient vertical depth to leave a space 13, (as shown in-Fig. 2) between the bricks 3 and the filler blocks 4 to permit vertical expansion of each brick in the wall. A small groove 14 may be provided in each end of the .brick for the insertion of fire clay, asbestos 'rope, or other compressible material 20, to seal the air passages from the furnace gases. .The filler blocks'4 (see Fig. 6') are shouldered or recessed at 19 for engagement with 'theheader brick, and vare of less thickness or depth into the wall, than the latter, so that the horizontal air assages 15, as shown in Figs. 2 and 3, are ormed by the spaces between the back of the filler blocks, the outer Wall structure 2, and the adjacent courses of header brick 3. At each end of each filler block, at a point intermediate the front and back faces, a groove 16 may be provided, the length of the portion of the block in front of this point being somewhat less than the length of the portion in back thereof, so that the blocks when in place, as in Fig. 3, make contact at 17 but have a space 18 for horizontal expansion at their exposed faces where they are subjected to the heat of the furnace. Vertical expansion is provided for, as shown in Fig. 2, by the clearance 13 already referred to. The grooves 16 provide for the insertion of the compressible material 20 (see Fig. 3), just as in the case of the header brick.
It is obvious that the exposed portions of the blocks, which are subjected to great temperature, are quite free to expand in any direction without binding and without the cracking, breaking or spalling incident there to, while the protected portions thereof, upon the very slight expansion which they undergo, tend to hold the wall firmly into its supporting structure. I
In the form of the invention illustrated in Figs. 7 to 11. I employ a modified form of header and filler block 3a and 40, similar in general form to the blocks of Figs. 5 and 6, but having the face portions 36 and 4?), respectively, oflset longitudinally of the brick so as to form lap or by-pass joint in the horizontal, as well as the vertical, courses, such joints being what are frequently called broken joints, i. e. joints formed with a right-angular break. The portions 3?) and 4?) are, as in the other form of brick, of such dimensions relative to the rear portions as to provide the same clearance or tolerance for expansion of the bricks on the exposed side; that is, expansion spaces 13 are provided for vertical expansion, and expansion spaces 11a and 18a (between header. and filler, blocks, respectively) are provided for horizontal expansion. The header blocks make contact .at the back at 9a (as in the first-described construction) to insure proper bonding into the supporting wall 2. In other words, as is evident from Figs. 9 to 11, the construction of blocks shown in Figs. 7 and 8 provides bypassed joints throughout the wall, both horizontally and vertically, giving absolute freedom of expansion for the fire face of each block; provides also vertical and horizontal air channels 6a and 15a (exactly similar to the channels 6 and 15 of Figs. 1 to 4) and insures against intermingling of the furnace gases and the air in the channels, by said bypassed joints, for no matter what conditions of expansion or contraction are present, the
adjacent blocks are always in slidin contact with each other. Adjacent header locks 3a are in contact at a (Fig. 11) adjacent filler blocks 40, are in contact at Z) (Fig. 10) and the header blocks are in contact with the tiller blocks at 0 (Fig. 9).
From the foregoing, it will be seen that I have provided a wall of great stability and strength, two courses of every three, of the refractory brick, being bonded into the supporting wall; a wall of substantially gastight unity; means for circulating air both vertically and horizontally for the preheating thereof and the cooling of the blocks; and full, adequate and complete compensation for the expansion of the individual bricks in any direction; and have accomplished the foregoing with the use of two simplefor'ms of block, a header block and a filler block, both of which are of solid and rugged construction and easy to make, since there are no cavities or passages within the blocks themselves.
