REvl-:RBERATORY FURNACE.
SPECIFICATION forming part of Letters Patent No. 525,113, dated August 28,' 1894.
Applicationfiled November 8, 1893. Serial No. 490,387. (No model.)
To aZZ whom t may concern:
Be it known that I, MICHAEL J. MURDOOH, a citizen of the United States, residing at Youngstown, inthe county of Mahoning and State of Ohio,have invented certain new and useful Improvements in Reverberatory Furnaces; and I do hereby declare the following to be a full, clear, and exact description of my invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
My invention relates to that class of reverberatory furnaces used in iron manufacture known as heating and puddlin g furnaces, and its object isa smoke consuming furnace that is simple in its construction, and that in operation is certain, under all circumstances, to
consume all of the smoke'that is generated therein, thus providing avv furnace of great economic value in the use of fuel, and whichV also does away with the smoke nuisance in the neighborhoodsin which used. I accomplish this object by the means hereinafter described and illustrated in the drawings, in whichi Figure l is a side elevation view of my furnace showing its exterior form. Fig. 2 is a similar view of a longitudinal vertical section of the same on the line rc :c of Fig. 4. Fig. 3 is a cross section view of the same on the line Q Q of Fig. 4; and' Fig. 4 is a horizontal section view of the same on the line y y of Fig. 2.
The parts are indicated by letters and similar letters refer to similar parts in allthe views.
My invention proceeds upon the idea of carrying all smoke, gases and carbonaceous particles that survive combustion from the point Where they otherwise would escape into the flue backward through the upper portion of the furnace Whe-re, having become sufficiently intermingled with steam and air, they are at once consumed. The wall tu is so formed at the grate end of the furnace as to give a con siderable vertical capacity to the combustion chamber c above the grate g, the same being covered by the dome h. The roof ato the working chamber o is the same as in the or dinary puddling furnaces except that at each The smoke return conduit o, formed bythe furnace top wall w and the second roof a', is an open, line like space, in breadth the distance between the side walls w3 of the furnace, and of suitable capacity to carry back to the combustion chamber c all the smoke generated. Its vertical portion is near to and parallel with the flue f, and its horizontal portion is above and parallel with the roof c.
The pipe p extending from a steam generating boiler to the flue f is there turned at an angle, and passing down the outer side of the flue to a point on the horizontal plane of the lower surface of the working chamber roof a is again turned at an angle and passed through the Wall 102 terminating a little distance inward. Two or more pipes may be used if desired. I have, however, found one to be generally sufficient.
The value of steam, especially of dry steam,
ejected into a burning mass to promote com bust-ion is well understood. It is for this, and also for the effect of its pressure incausing the smoke to pass backward through the conduit o, that I use it in myfurnace.
The several doors d are for access to the various interior spaces in the walls in which they are placed. The form of the furnace shown in the drawings does not differ substantially from that of the heating and puddling Vfurnaces now in use, and hence need not be more particularly described. The same is true of the grate g, the bridge wall b, the working chamber bottom s and the flue f.
It .will be seen that the new features con- 'sist of a steam pipe p, the smoke return con`` duit o, the dome shape of the furnace top wallabove the combustion chamber c, and
the working chamber roof a having the hollow space o and the air inlets e', all of which have been fully described and will now be understood.
What I claim is- 1. A reverberatory furnace having the working chamber o', the flue f commu nicating with the chamber o `opposite the grate end, the return conduit o `having vertical connection with the rear end of the working chamber independent of the due f, and communicating at its forward end with the combustion chamber, the transverse flue V near the forward end of the working chamber communicating at its ends with the air and having a series of inlets c', and a steam pipe disposed to create a draft through the vertical and horizontalportions of the return conduit to convey the smoke and gases back to the combustion chamber, substantially as described.
2. The herein described reverberatory fur-` nace having its side walls converging, and having a dome over the combustion chamber,
a working chamber communicating with the combustion chamber, a iiue f leading into the rear end of the working chamber, a return conduit above the working chamber formed between the side, end and top walls of the furnace having vertical connection with the rear endof the Workingchamber independent of the flue f, and having communication with the combustion chamber by means of the said dome, a transverse passage V extendiup` through the side walls of the furnace having Vertical inlets t', and a steam pipe having` communication with thefurnaceand arranged to create a draft'through the vertical and horizontal portions of the said return con duit, substantially as described for the purpose specified.
In testimony whereof I hereunto affix my signature in the presence of two witnesses.
