FURNACE.
SPECIFICATION formingpart of Letters Patent No. 680,521, dated August 13, 1901.
Application filed May 16, 1901. Serial No. 60,491. (No model.)
To all whom, it may concern:
Be it known that I, ALPHONSE L. For, a citizen of the United States, and a resident of New York, borough ofBrooklyn,in the county of Kings and State of New York, have made and invented certain new and useful Improvements in Furnaces, of which the following is a specification.
My invent-ion relates to an improvement in boiler-furnaces, and more particularly to means for supplying air to the fire-bed for the purpose of increasing and perfecting the combustion of the coal and gases. Many devices have been constructed for this purpose, the one most generally used being the steam-jet blower, and while an increased supply of air is afforded thereby, yet it is always open to the objection that by reason of the moisture in the steam the boiler is corroded and injured.
One object of my invention is to supply to the fire an increased supply of heated and dried air, not only under the fire-bed, but also above it, whereby the gases in many cases escaping through the fiues will be entirely consumed.
A further object of my invention is to provide means whereby the air may be directed to all parts of the fire-bedthat is, along its sides and at the rear-so that the fire may be kept bright and even, and also to provide means whereby the quantity of air directed to either side or at the rear and also above and below the fire-bed may be nicely regulated; and with these and other ends in view the invention consists in certain novel features of construction and combinations of parts, as will be hereinafter fully described, and pointed out in the claim.
In the accompanying drawings, Figure 1 is a view in side elevation of a boiler-furnace, a portion of the wall being broken away for the purpose of illustrating the air-fiues. Fig. 2 is a sectional view taken on the line 2 2 of Fig. 1, and Fig. 3 a similar View taken on the line 3 8 of Fig. 1.
Referring to the drawings, A 13 represent the two side walls of the furnace, O the rear wall, and D the transverse or bridge wall, usually constructed of brick and inclosing a boiler E of any desired kind or character, and forward of which is a grate F. In these side walls AB are formed the main flues a a, comformed the branch fiues or air-passages cf,
the former at a height above the grate and the latter below the grate, the three fiues or passages e, a, and fcom mu nicating with each other by means of the vertical flue or passage d, into which the forward ends of said fiues lead. In the opposite side wall B are also formed corresponding fiues or passages ef, which are also of a length equal to the depth of the grate F, the former at a height above the grate and the latter below the grate, the three passages or fiues e a f communicating at their forward ends by means of the vertical passage 61, into which said three passages or fiues lead.
In the bridge-wall D is formed a passage 0, communicating with the rear ends of the fiues e e, and also the flue c, communicating with the rear ends of the fiues ff, this construction and arrangement resulting in the formation of practically two fiues, one above the grate and the other below the grate and eX- tending along one side of the latter, then back of said grate, and then around the opposite side of said grate, which two fiues communicate with each other by reason of the said vertical fiues and also with the fiues a a, which extend the entire length of the two walls A 13.
From the passages e e, ff, and c 0 lead openings 2' into the fire-chamber and ash-pit, or, in other words, at points above and below the grate F, for the purpose of directing the air from said passages above and below the fire-bed, as hereinafter described. In the vertical passage d I place sliding dampers k, and in the vertical passage d I place the sliding dampers 70, whereby communication of the branch or short horizontal fiues e e and f f may be out oif from the main fiues a a.
Having fully described the construction IOC and arrangement of my new device, I will now describe the operation thereof: Air is forced through the main fines a a, and by reason of its travel along the side walls inclosing the boiler E it is heated and dried. If all the dampers be open, the air passes into the vertical fines d d and then through the branch fines e e, ff, and c c" and through the holes or openings 1' above the fire-bed, supplying a snfficient amount of oxygen to cause the gases above the fire-bed to be consumed and also a snfiicient amount of air below the fire-bed to materially increase the draft through the same. By locating the passages as above described a current of air is supplied both above and below the fire-bed and at the two sides and rear thereo i, the ad van tage of which will be immediately apparent to those skilled in the art. If it be desired to supply air below the fire-beds only, the upper dampers 70 7c are pulled outwardly, thereby shutting off communication of the branch passages e e c with the main fi ues a a, thereby directing all the air from said fines a adown into the fines ff 0' and from there into the ash-pit under the grate F. If, on the other hand, it becomes necessary to supply the air to and over the largely to one side of the bed and but little to the opposite side, the arrangement of dampers and fines permitting the fire-bed to be kept even and bright by properly adjusting said dampers.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
In a furnace, the combination with the side walls having horizontal main air-passages formed therein, and extending the length of said walls, and with vertical air-passages at the forward ends of said main passages, and communicating therewith, of a grate located in the forward end of said walls, auxiliary fines located in said side walls above and below said main fines and above and below said grate, the forward ends of said auxiliary fines communicating with said vertical fines or passages, a bridge-wall connecting said side walls, and having fines therein above and below said grate and communicating with the rear ends of said auxiliary fines, and dampers located in said vertical fines whereby any or all of the air passing through the main fines may be directed above or below said grate, substantially as described.
Signed at New York, in the county of New York and State of New York, this 14th day of May, A. D. 1901.
