SIVIELTING- FU RNACE.
SPECIFICATION forming part of Letters Patent No. 265,128, dated September 26, 1882. Application tiled February 8, 1882. (No model.)
To all whom it may concern Be it known that I, CHARLES HAMMOND MURRAY, a citizen of the United States, residing at Leadville, in the county of Lake and State of Colorado, have invented a new and useful form of Stitching-Furnace, entitled a Gas-Flame Blast-Furnace,7 of which the following is a specification.
This invention 'relates to an improvement in furnaces for smelting ores; and it consists in the combination and arrangement of devices substantially as hereinafter more fully set fort h and claimed. f
The character and construction of the furnace is shown in the accompanying drawings, of which- Figure l is a transverse vertical section of the furnace, the gas-chambers, and the fuelchambers as they stand in relation to one another. Fig. 2 is a side view of the fuelchamber, indicating` the position of the airpipes, the grate-bars, and the cindcr-doors. Fig.3is asectionalviewon the lincxmot' Fig. l..
Thefollowing is a detailed description of the invention. y
The purpose of my invention is to secure the I burn the fuel sufficiently to convert all its heat-making ingredients into gases. This is accorti- Vplished in fuel-chambers outside ofthe smelting-furnace, and before the gases have 10st much of their heat by radiation or conduction `they are introduced into the slnelting-furnace in conjunction with jets of air, and there complete their combustion, suitably affecting the ores. To accomplish this I construct a fuelchamber, A2, and a gas-chamber, Ai. on each sideotl the smclting-furnaceAand in close proximity to it. Thefuel-chambers have midway between their grate-bars and the top of the chamber a slide, B, that serves as a bottom to receive the fuel when it is fed into the top of the chamber. This slide is constructed to push in or pull out by means of a lever, B', attached to its outer edge. It is made to tit close inthe wall, where itis worked in or out. The plate B being shoved in, the fuel is putin at the top door, A, which is then shut down air-tight, and the plate B is withdrawn, and the fuel is left free to settle as it is consumed below. In the lower part of the fuel-chamber, below the eighths of an inch wide.
ries with it `any vapors or smoke that may be A forming. These pipes are shown in Fig. 2. The lower set of air-pipes, (four or more in number,) B3 B3, penetrate the chamber atits front a few inches above the grate-bars. and keep the fuel in glowing incandescence. Through this heated fuel the smoke and vapors from above are caused to pass by the upper air-pipes, thereby burning the smoke and decomposing any aqueous vapors. The fresh air that comes down from the upper set of air-pipes, or that introduced by thelower set1 is made to pass through several inches of glowing coal, which converts the carbon into carbonio-oxide gas. y These gaseous products are forced downward through the grate-bars, and pass, as indicated by the arrow. u p into the gas-chamber. From this chamber they are passed simultaneously into the smelting-furnace through corrugations in the plate C. This plate C is the roof or covering of the gas-chamber, and separates the gas-chamber from the fresh-air passage above. It is in ade of sheet-copper, and'is ben'tor pressed into corrugations, as shown in Fig. 3, which is an illustration of a cross-section of the plate. The corrngations or channels in the .plate are about seven-eighths of an inch deep and three- The gases enter the iiame-spaceofthesmelting furnace through the under channels of the plate C', these channels being lettered f/ g g, Fig. 3, while the fresh air is introduced through the upper channels, d a a, thus causing the gases and fresh' air to enter the flame-space in the smelting-furnaee in contiguous alternatingujets on the same plane, where thecombustionofthegasesis completed.
Above the gas-cliamber,and separated from it by the plate C', is an inclosed fresh-air passage. Into this fresh-air chamber or passage fresh air is introduced by a blast and forced into the smeltiug-furnace through the upper channels on the plate O', as indicated by the arrow. The upper plate or roof of this freshair passage may be ot' sheet-iron, and riveted to the plate C where the two come together.
(See the crosssectional view, Fig. 3.) The plate C and this air-chamber are arranged to extend across the whole Width of the smeltin gfurnace, and the opening in the latter for the introduction of the gases and the fresh Iair is unbroken, or extends the full width of each side of the furnace. The mouth of the freshair passage, which includes the end ofthe corrugated plate C', fits tightly into the opening on either side of the smelting-furnace, and is a substitute for any kind of tuyere commonly employed.
In order to secure space for the generation and sustenaneeof agas-iiame, the Water-jacket on the sides of the smelting'furnace is cut across horizontally and lengthwise ot' the furnace and divided into upper and lower sections. Between these sections is the opening for the introduction of the fresh air and gases. Where these upper and lower sections app roach each other they are curved, the curves opening to the inside of the furnace, as shown in Fig. l. The upper section is constructed to V leave an opening about one inch wide between .inches farther into the furnace on either side of the furnace than the curve on the lower section. By this construction the descending ore is held off and prevented from clogging or lling up the flame-space between the two curves. Abovethe curve, on the upper section of 'the jacket, the bosh of the furnace slopes outward at a sharp angle, so that the ore above the smelting-zone may be loose and allow the products ot` combustion to freely escape into the stack above.
It must be understood that the above descrip'- tion applies to rectangular furnaces only.
The two doors represented on the side of the fuel-chamber, Fig. 2, are for the purpose of removing any clinkers from the fuel-chamber. To insure their shutting air-tight, they and also the door A on the top of the fuel-chamber are bordered on their margin with asbestus felt.
Having thusfully described my invention, l claim and desire to secure by Letters Patentrlhe combination, in a blast-furnace, of the smelting-chamber A', provided on each side with a horizontal blastopening, a gas-generating chamber, A2, on each side, connecting gastlues A3, air-blast chambers C, having bottom corrugated plate, C', the whole constructed as described, whereby the corrugated plate forms the roof ot'the deliveryend of the gas-tlue, substantially as set forth. y
