`BLAST'f-FURNACE FOR BURNING GASEOUS FUEL.
SPECIFICATION forming part` of Letters-Patent No. 288,60*?dated November 13, 1883,
Application ilerlFebrnary 1'2, 1853.
To zZZ wiz/0.777, it may concern:
Be it known thatl, LEVI D YORIQ of Ports` mouth, Scioto county, in the State of Ohio, have invented certain new and useful Improvements Relating to Blast-Furn aces, of which the following is a specification.
I work the furnace by forcing in at the bot- .tom air and gas, both at a high temperature.
I can use solid fuel in a less proportion t-han usual, or I can dispense with it entirely, and produce the heat from the combustion alone of the gas thus forced in.
The following is a description of what I consider the best means of carrying out the invention.
The accompanying drawings form`a part of this specification.
Figure 1 is a vertical section, some of the parts being in elevation. Fig. 2 is an outline, showing a different arrangement of the parts. This involves a somewhat different mode of working.
Similar letters of reference indicate correspond ing parts in both figures.
Referring to Fig. l, A is a blast-furnace, which` may be of ordinary dimensions, form, and proportions.
B is an air-heating stove, performing the usual functions of such device by absorbing heat from the products of combustion escaping from theblast-furnace through the pipes b, and imparting it to fresh air forced by the blowing means C through the pipe c, and thence through tuyeres c into the furnace A at several points near the base. The blower G is driven by an engine or other power. (Not represented.)
It will of course be understood that pipes c and d continue from the blowers'to the tuyeres c and iire-box E, and that the portions within thestoves B F are adapted to be bathed by the heated gases which enter into the stoves through the pipes b, the said gases thence passing to the outer air through passages. (Shown in dotted lines.)
The gas-producing vfurnace E is kept filled with bituminous coal o r other suitable solid fuel, inlumps of proper size to allow the air a tolerably free passage through its interstices. D is ablowing apparatus,which is workedby an engine or engines. (Not represented.) This blower D forces the air through a pipe, d, and
(No modcLi heating stove F into the base of the gas-pro t ducing furnace E.
The fuel in the furnace `Fl is maintained at e such depth that the gases rising therefrom are largely carbonio oxide and hydrocarbon gas iiux being reduced, the zone of preparation is diminished, and may be done away with altogether when sufficient gas is used to supply heat, requiring only ore and flux to be put into the blast-furnace at the top.
My furnace is more efficient than ordinary blast-furnaces, for reasons long recognized in various forms of low furnaces. A given size `of furnace is more efficient andthe fuel is economized. The quantity of combustible gas and of air is controlled by workingthe blowers C and D at varying rates, or bythe employment of any suitable valves, as indicated, or by both these means.
In the form of apparatus shown in Fig. 2, instead of forcing the air before it is supplied to the gas-furnace, the blowing apparatus is placed intermediate between the gaseproducing furnace and the blast-furnace.
It will be understood that the gas is considerably lowered in temperature, either by radiation from the pipes, or by its passage through one or more pipes specially cooled by means not represented, so that it reaches the blowing means at a temperature that allows it to be worked. I propose to determine by experiment what is the highest temperature at which gas can be pumped or otherwise forced, and take care to never have the gas exceed that te1nperature. This form of the apparatus gives that the proportion of solid fuel to the ore and y the advantage that the gas-producing furnace IOO L) agace? It will also be understood that the blast-furnace l I have represented in Fig. 2 but one blower,
itself and its several auxiliaries may be varied in proportions and in arrangement.
I have omitted much detail in the drawings. Each of the parts may be made in any ordinary or suitable manner, and with all the necessary attachments. It is essential only that a liberal supply of combustible gas be obtained from a gas-producing furnace, E, and be driven into the base of the blast-furnace A, and that a sufiicient quantity of fresh air be properly present ed thereto in the blast-furnace, and that both be supplied hot.
. The main pipes may he placed under ground or over head. The gas and air may be passed into the furnace at the same level. In such Casethetuyeres for the two may have their openings of proper dimensions arranged at an angle, so as to cause the jet from one gas-tuyere to impi-nge upon the jet from an adjacent air-tuyere. I can use any desired number of tuyeres.
Any ordinary or suitable form of air-heatin g stoves may be used for the stoves B and F.
D, and but one heating-stove, F; but it will be understood that there are corresponding blowing means and heating-stove to supply the hot air. I have not deemed it necessary to showin Fig. 2 the air-supplying apparatus further than the pipe through which the heated air is received.
I claim as my invention- In combination with the blast-furnaeeA and air-heating stove B, and its connections for ruary, 1883, in the presence of two subscribing witnesses.
