ATTORNEY Patented Dec. 16, E94? STATE PATENT OFFICE I BLAST FUBNACE STOVE CHECKER william M. Bailey. Pittsburgh, ra. .Application December 22, 1944, Serial No. 569,344 4 Claims. (Gl. 263-51) This invention relates to checkers and checker tile for use in industrial heating furnaces, more particularly for hot blast stoves, and it is among the objects thereof to provide checker tile shaped to obtain maximum heat exchange surface and minimum of weight for a given space.
It is a further object of the invention to provide refractory tile for checkers in which the ends and side Walls are recessed to form cooperating walls of passages placed in cooperative abutting relation with minimum resistance to the ow of gases and air therethrough.
It is a still further object of the invention to provide a checker tile of a shape and dimensions to form a series of vertical flues of predetermined cross-sectional area communicating with one another through passages constituted by the form of the tile when laid up in abutting transverse checker arrangement.
These and other objects of the invention will become more apparent from the accompanying drawings constituting a Part hereof, in which like reference characters designate like parts, and in which Figs. 1, 2 and 3 are a top elevation partially in section, a side elevation and end elevational view respectively of a checker tile embodying the principles of this invention Fig. 4 is a horizontal cross-sectional view of a portion of a checker-work constructed of the tile shown in Figs. 1 to 3 taken through the center line of the assembled tile;
Figs. 5, 6 and 7 are a top plan partially in section, a side elevation and an end elevational View, respectively, of a modified form of checker tile, and
Figs. 8 and 9 are a horizontal cross-section and perspective view respectively of a checker-work embodying the tile of Figs. and 7.
With reference to the several figures of the drawings the numeral I designates a clay or other refractory tile of a convenient dimension such as a 3" x 6" x 15" brick having V-grooves 2 formed in the end faces 3 thereof and having recesses 4 in the side walls 5 thereof, the V-grooves 2 being of approximately one inch depth and the recesses 4 three-quarters inch in depth. As shown in Fig. 4, the tile I is laid up that the ends 3 abut the side faces 5 at substantially the center thereof forming passages constituted by the walls 2 and 4 to the flues constituted by the spaces between adjacent tile, these spaces for a tile of 3" x 6" x 15" dimension being 6" x 6". I'hus every flue is in communication with adjacent fiues through a passage constituted in a checker-work so by the grooves 2 and 4. The tile are built in layers to form a checker-work as for example for a hot blast stove of any desired height.
In the form of tile shown in Figs. 5 to 9 of the drawings, the end faces 6 are provided with arcuate shaped grooves 'l which cooperate with the grooved recesses 8 of the side Walls 9 of the tile to form flow passages between adjacent ues designated by the numeral I0, Fig. 8, these passages being rounded to offer minimum resistance to the flow of the gases or air between adjacent fiues, the form of recesses shown in Figs. 5 to 9 being the preferred form.
The form of tile hereinabove described increases the heating surface per cubic foot of space over conventional forms heretofore employed by nearly thirty percent Without increasing the cost per square foot of surface, and may be speedily erected in industrial regenerative heating furnaces and particularly hot blast stoves.
Although several embodiments of the invention have been herein illustrated and described, it will be evident to those skilled inthe art that various modifications may be made in the details of construction without departing from the principles herein set forth.
I claim:
1. A tile for checker-works comprising a rectangular shaped refractory block having grooves of substantial depth and width in the end faces thereof and having the side walls grooved over a substantial length thereof with grooves of substantially the same width as the end grooves to form cooperating walls of passages when laid up in abutting'relation.
2. A checker-work for industrial heating furnaces comprising refractory tile of rectangular shape arranged with the end faces of some of the tile abutting the side faces of adjacent tile at substantially the center thereof to form rectangular vertical fiues, the end and side faces of abutting tile having grooves or notches forming communicating ow passages between adjacent ues.
3. A checker-work for industrial heating furnaces comprising refractory tile of rectangular shape arranged with the end faces of some of the tile abutting the side faces of adjacent tile at substantially the center thereof to form rectangular vertical flues, abutting end and side faces of adjacent tile having grooves and recesses forming flow passages communicating between adjacent flues.
fi: A checker-Work for hot blast stoves comprising refractory tile laid up box type in superposed relation with the end faces and side walls oi' adiacent tile abutting to constitute parallel vertical llues, said tile having their abutting end faces and side walls depressed to constitute cross circulating fiues for the gases passing through said 5 vertical tlues. v
