To all whom zit nuty concern.-
Be itknown thatI, JOHN W ARRENREAGAN, a citizen of the United States, residing at Powell Station, in the county of Knox and State of Tennessee, have invented a new and useful Improvement in Brick-Kilns, of which the following is a specification, reference being had to the accompanying drawings.
My improvement relates particularly to that class of kilns which comprise one or more relatively large compartments for the reception of the brick to be burned and a plurality of external furnaces communicating with said chamber or chambers and a plurality of chimneys or lines for the escape of the products of combustion after emerging from said furnaces into said chamber or chambers and traversing the latter.
The object of my invention is to produce a kiln adapted for an even distribution of heat to all the brick within said chamber or chambers, such even distribution being effected by a mechanical construction and arrangement which compels the products of combustion passing from the furnaces to follow courses on the way to the fines which will bring to all portions of the masses of green brick a due proportion of said products of combustion.
In the accompanying drawings, Figure 1 is a horizontal section of a kiln embodying my improvement, the section being taken just above the floor. Fig. 2 is an upright section on the line 2 2 of Fig. 1 looking in the direction of the arrow. Fig. 3 is an upright section on the line 3 3 of Fig. 1 looking in the direction of the arrow. Fig. A is an upright section on the line 4 4. of Fig. 1 looking in the direction of the arrow.
A A are two main parallel chambers bounded on the exterior by side walls B .B, end walls C C, and arched ceilings D D, and said chambers are separated by a row of upright chimneys 1 and walls 2. closing the spaces between said chimneys from said ceiling downward far enough to leave the arched openings 3.
E E are furnaces located along the base of the outer portion of the side walls B B and communicating with flues extending through said walls into the chambers A A. Each of said furnaces has a front wall 4:, side walls 5 5, a top wall 6, a fire-door '7, an ash-door 8, and a grate 9. These furnaces may be of any desired or well-known construction adapted to properly burn the fuel and deliver the products of combustion into the fines leading through the adjacent wall B. Said flues are arranged with a view to a delivery of said products of combustion into the adjacent chamber A in a multiplicity of streams properly distributed along the length of the chamber and at such elevations as will effect a delivery of equal quantities of heat to all of the green brick in said chamber, and the arrangement of the chimney-lines and the floor-fines, to be hereinafter described, is such as to induce a proper movement of such multiplicity of streams of products of combustion through the mass of green brick.
From the middle of the base of each furnace E a flue 10 extends horizontally through the adjacent wall B at substantially the level of the floor of the adjacent chamber A. At each side of such central fine 10 a flue 11 extends a short distance into the adjacent wall B parallel to the line 10 and thence horizontally away from said line 10 at right angles to the latter and thence again parallel to said fine 10 through the remainder of said wall B into the adjacent chamber A. The discharge ends of said flues 10 and 11 are preferably separated from each other suitable distances to bring the entire series of said openings through the same wall B substantially equidistant from each other.
From the floor of the chamber A near each wall B a flash or deflecting wall 12 extends from one end of the chamber A to the other parallel to the walls B and to approximately half the height of the chambers A, as indicated by Figs. 2 and 4. Between the lines 10 and 11 said flash-wall is joined to the adjacent wall B by upright connecting-walls 13, extending from the floor to the top of the flashwall. Said connecting-walls serve to impart stability to said flash-wall and also to maintain a separation of the streams of combustion products emerging from the discharge ends of the fines 10 and 11. At the level of the floor in line with the discharge end of each flue l0 and 11 a port 1% extends through the flash-wall. Farther up in said flash-wall in an upright line extending upward from each aperture 1 1 and between the connecting-walls 13 are more ports 15, corresponding to the ports let. The drawings show three such ports 15 above each port 14, and between the upper ing 16. The flash-wall 12 may embody any well-known provision for expansion.
In an upright plane parallel to the row of chimneys 1 the chimneys intermediate the ends of said row each have two upright flues 17, separated from each other by a partitionwall 18. The chimneys at each end of said row are preferably provided with only one fiue 17, and each such end chimney is preferably set close against the adjacent end wall 0 in order that the prod nets of combustion from the adjacent furnaces may be led across the chambers A close to the end wall 0 for the complete heating of the bricks stored against said end wall. The flue 17 of each of said chimneys is provided with two ports 19-, one being directed toward one of the side walls B and the other toward the other of said side walls B, said ports being at the floor-level. In the others of said chimneys each fiue 17 has one similar port 19, the port of one of said fines being directed toward one side wall B, while the port of the adjacent flue is directed toward the other of said side walls.
In each space between two adjacent chimneys are located one or two fioor-fiues 20, the same being open channels or trenches extending downward from the fioor in line with the row of chimneys and into one of the chimneys. There may be only one such fioor-fiue continuous from one end of the kiln to the other; but it is preferable to make a plurality of such fiues by means of the chimney-partitions 18, which separate the fiues 17 in the intermediate chimneys, and by means of upright transverse partitions 20.
The arched ceilings D D rest on the side walls B B and the walls 2, which are located between the chimneys. In the crowns of said arches are ports 21, and at each end of each chamber A the end walls are pierced by doors 22, which are to be closed in any suitable manner during the burning of a charge of brick.
Any desired number of buckstays 23 may be set upright against the exterior faces of the walls of the kiln and suitably secured at their bases and connected in pairs by horizontal binding-rods 24, extending across the top of the kiln. In the drawings such buckstays are shown applied to the exterior of the side walls B in the spaces or alcoves 25 between the furnaces E and joined by transverse binding-rods. By reference to Fig. 1 it will be seen that said alcoves are so set that a horizontal line cutting opposite alcoves will pass between chimneys. This results in the passing of the binding-rods 24 between chimneys. Such location of said alcoves results from placing the furnaces with their middle transverse lines coincident with a horizontal line transversely cutting through the middle of a chimney.
From the foregoing description the operation will be readily understood. It is as follows: After the brick are stored in the chambers A A the chimneys are partially covered, so as to limit the down and cross draft, and
at the same time the ceiling-ports 21 are opened. The fires in the furnaces are then operated until the brick is dry, the products of combustion passing through the wall-fines 10 and 11 and into the spaces between the side walls B and the flash-walls 12, ports 14 and 15 in the flash-walls, and through the openings 16 at the upper edges of the flashwalls. The products of combustion issuing from the ports 14 (which are at the fioor) go horizontally across the chamber A, through the lower portion of the mass of green brick and enter the chimneys through the ports 19 or through the fioor-fiues 20. It will be observed that said products on entering the floor-fines fiow to the right or left in said fiues and enter the adjacent chimney-fines 17. If so desired, the chimneys may be covered to such extent that only a portion of said products issuing from the ports 14 will enter the chimneys, the remainder risingthrough the mass of brick and passing through the ports 21. All or substantially all the combustion products issuing from the ports 15 and openings16 move laterally and upward through the ports 21. When the bricks are dry, the ports 21 are closed and the chimneys uncovered. Then all the combustion products from the ports 14 go through the chimneys, and the products of combustion issuing from the apertures 15 in said flash-wall move horizontally and downward to the said ports 19 and fioorfiues 20. The products of combustion issuing from the openings 16 move across the upper portion of the chambers A, and thence downward to said ports 19 and floor-fines 20.
It will be observed that the products of combustion are divided into a large number of distinct streams. According to the construction shown by the drawings there are in each chamber A one hundred and five such streams or two hundred and ten in the entire kiln, audit will be observed that said streams are well distributed with reference to the length and the height of the charge of brick in each chamber A.
When so desired, the fiow of the products of combustion may be varied or modified by opening the ceiling-ports 21. If, for example, it is found that the upper portion of a charge is not sufiiciently burned, said ports may be opened, whereupon a portion or all of the products of combustion after issuing from the flash-wall ports will rise through the upper portion of the charge and pass thence through the ceiling-ports.
