ORE-ROASTER.
SPECIFICATION forming part of Letters Patent No. 520,481,dated May 29, 1894. Application filed June 21, 1893- Serial No. 478,319. (No model.)
Roasters, of which the following is a specification.
My invention is an improvement in ore roasters of that class shown in application filed by me in the United States Patent Office on the 6th day of July, 1892, Serial No. 4 38 991, and includes an ore space, a combustion chamber or a series thereof, and a draft or fine space, the ore space being between the combustion chamber so that the heat may of ore.
In the present invention I aim to buttress the lnner walls of the combustion chamber so as to resist the pressure of ore; to provide at the same time for a circulation through the buttressing, and finally to provide horizontally-arranged combustion chambers instead of vertical as in my former application reand flue or draft space pass through the mass In the drawings Figure 1, is a vertical section through a portion of a furnace con structed according to my invention with horizontal combustion chambers. section of the same onlinew 0c of Fig. 1. Fig. 2 is a view of the combustion chamber wall. Fig. 3, is a vertical section of a furnace provided with vertical combustion chambers and buttressed according to my invention. Fig. 4 is a View of the buttress wall.
In the drawings is shown a stack 1 of circular form but the invention is not limited to this form, being applicable as well to any other.
There are two parts of the invention, the first relating to buttressing vertical walls, between the inner and outer Wallsof the combustion chamber, said walls being made of open work, or solid with lateral passages, between contiguous sub-divisions of the combustion chamber, which is divided by said buttressing wall into said sub-divisions. The second part relates to a further subdivision of the combustion chamber by horizontal partitions, with each one of which I have shown a separate gas pipe and air inlet, making a Fig. 2, is a horizontal series of combustion chambers arranged horizontally, one above the other.
In Fig. l,the outerwall D is solid as usual except for the air inlets and gas inlets. The inner wall 0 of the combustion-chamber is formed with openings 2, between the bricks 2 Fig. 2 leading to the ore chamber. These are shown in section and front elevation as extending across between the vertical subdivisions formed by the buttressing walls E. These buttressing walls connect theinner and outer walls above described, which form the combustion chamber. The combustion chambers extend horizontally around the f urnace, being supplied with gas. and air as at a, and b, respectively, these chambers being arranged in a series, one above the other, but each preferably independently supplied with fuel. The gas passage a may communicate with any suitable inlet port as at at, Fig. 1, and holes a are provided for the escape of the gas from the gas passage to the combustion chambers. The gas passage is formed by horizontal partition plates or bricks 0. The horizontal division walls forming the horizontal chambers thus aid to strengthen the structure and resist the pressure of the ore, and the series of vertical partitions, which extend from the inner to the outer walls of the combustion chamber, as at E, still further add to the strength of the structure. These prevent the crushing of the wall between the horizontal partitions. The vertical partitions may mark the division walls of the openings 2 to the ore chamber and in this case the openings may be arranged out of line with each other as shown in Fig. 2.
In order that the vertical partitions may not separate the horizontal chambers into a series of independent chambers I prefer to provide passages 20 Fig. 1 in these walls so that there may be connection between all the compartments of each horizontal chamber. As usual the lower wall of the opening is inclined to prevent lodgment of the ore.
In Fig. 3, I have shown a furnace with a vertical combustion chamber and this chamber is divided bya series of vertical partitions extending between the front and rear walls of the chamber so as to buttress the same. In this case the inner wall is shown at C, the outer wall at D and the partition wall at E. In this form the openings 2 to the ore chamber are in line with each other and the buttressing extends from top to bottom as shown, openings 20 being left in the partitions at intervals to allow circulation between the chambers. The gas and air inlets in this form may be arranged in any desired manner. Said inlets 01, a indicated in Fig. 3, are merely representative of any preferred form.
I claim- 1. In an ore-roasting kiln having inner and outer walls forming a combustion chamber, vertical buttressing walls connecting said inner and outer walls, and forming sub-divisions of said chamber, said buttressing walls being formed in open work or with passages, substantially as described.
2. In an ore-roasting kiln,havinginner and outer walls forming a combustion chamber, vertical buttressing walls connecting said inner and outer walls and forming sub-divisions of said chambers, and horizontal dividing walls, substantially as described.
3. In an ore-roasting kiln having inner and outer walls forming a combustion chamber, a series of horizontal walls, sub-dividing said chamber, with suitable fuel supply ports in connection with said combustion chamber, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
