FURNACE.
SPECIPICATIQN forming part of Letters Patent No. 317,852, dated May 12, 1885.
Application filed September 25, 1884.
To all whom it may concern:
Be it known that I, J osnr REULEAUX, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain 5 new and useful Improvements in Puddling and Heating Furnaces; and I do hereby declare that the following is a full, clear, and exact description of the invention, which 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 has relation to furnaces for puddling and heating of that class employing r gas as a fuel. In this class it is usual and necessary to heat the air by which the gas-flame is supplied, and it is ordinarily done by taking the air in at the back and bottom of the furnace, leading it forward to the front and then back under the melting-chamber to the rear wall, where it commingles with the gas, and from thence passes to the combustion and melting chambers.
My invention has for its object the provision 2 of a furnace wherein the air will be heated to a higher degree than in other known furnaces of its class, and more perfect combustion of the gas, and consequent economizing of time and fuel accomplished.
My invention has for its further object the provision of means whereby the flames from the combustion-chamber will be directed to and strike the material in the melting-chamber just inside the door of such chamber, and 5 thereby maintaining the metal at that point at a higher degree of heat than elsewhere in the chamber, so as to compensate for the cooling effect of the draft, which is set up when the door is opened.
These objects I accomplish by the peculiar construction, combination, and arrangement of parts hereinafter fully described, and illustrated in the accompanying drawings, where- Figure 1 is a vertical longitudinal section; Fig. 2, a vertical transverse section on the line 3 4 of Fig. 1; and Fig. 3, a horizontal section on the line 1 2 of Fig. 1 of a furnace constructed according to my improved plan.
Referring to the drawings, A designates the (No model.)
[ melting-chamber, having an arched top,.A,
and metallic bottom A.
B designates the combustion-chamber,which is inclined in the direction of the meltingchamber A, and is formed with an arched top, B, extending from the top A of the melt ing'chamber to the rear wall, 0, of the furnace. I
B B designate the side walls of the com bustion-chamber, and O O the side walls of the furnace, which are set out at some distance from the walls B B, so as to leave a clear space, I; b, on each side of the combustionchamber, and the walls 0 (J arejoined by an arched top, 0, between which and the top of 6 5 the combustion-chamber is left a space, 0.
B designates the bottom of the combustionchamber, extending from themelting-chamher A to a division-wall, D, between which latter and the rear wall, 0, of the furnace is a wide space, E, which forms the miXing-cham' her, where the air and gas are brought together and mingled.
A horizontal grating, F, formed offire-brick or other suitable material, divides the mixingchamber E into two divisions, e c, the gasburner G being located in the lower division,
6, and near the bottom thereof, and a similar grating, D, is formed in the division-wall D. The spaces or openingsin the latter alternate 8) in position with the spaces or openings in the horizontal grating F, so that the currents of air (which emerge throughv D) will be interlarded with the currents or jets of gas emerging through the spaces in F, thereby facilitating their instantaneous commingling.
H designates the bottom of the furnace, and I a false or supplemental bottom, arranged be tween the bottom H and the bottoms of the melting and combustion chambers. 3
K designates the air-inlet, and L the flue which returns the air back beneath the melting and combustion chambers to the mixing chamber E. The air is not, however, permitted to pass uninterruptedly through the flue L, as at about the middle of the combustion-chamber is a wall, M, that not only completely cuts off the flue L, but extends up through the spaces 1) b and slightly into the spaces 0 on top of the combustion-chamber. Ioo
Having described the arrangement of the flues, &c., I will now proceed to describe the means by which the flame from the combustion-chamber is directed to the portion of the melting chamber where the draft from the door strikes the contents of the same.
As has already been described, the combustion-chamber slopes downwardly toward the melting-chamber. In addition, the vertical Wall at the side of the combustion-chamber farthest from the door slopes toward the door from the rear wall, 0, forming a shoulder, a k, with the curved back of the melting-chamber, the opposite vertical wall of the combustionchamber being curved around toward the door (lettered N) on the line Z. The outlet from the melting-chamber to the stack is lettered O, and is situated forward of a line running longitudinally through the center of the furnace. The flames passing through the combustionchamber are deflected forward by the sloping wall of the combustion-chamber, and the po-.
sition of the outlet from the melting-chamber further aids in directing the flames to the proximity of the door.
Operation: The gas being turned on and ignited, the air is drawn in through the flu cs K and around over the false bottom H, and be tween it and the bottoms of the melting and combustion chambers by way of flue L until it reaches the wall M, by which it is deflected up through the passage 6 b on each side of combustion-chamber B, thence around through space 0 on top of the combustion chamber,
' downwardly through passage 1) b and into flue L again, and thence through the grating D to the mixing-chamber E, where it meets and mingles with the gas, the flames and products of combustion passing off through the combustion and melting chambers to the stack.
It will be observed that the air passes beneath the entire length of the melting-chamber and pursues a sinuous course completely around the combustion-chamber, thereby assisting to prevent the burning out of the walls of the same, and becoming heated to a very high degree before meeting the gas.
The peculiar arrangement of the gratings F and D'insures the entireand perfect mingling of the gas and air, and the peculiar form and arrangement of the combustion and heating chambers causes the flames to be most strongly directed to that point needing the most heat- 1'. 8., directly back of the door.
I am aware that it is not new to constructa furnace wherein air-flues are provided which pass beneath the melting and combustion chambers, and, emerging beneath the latter, join the gas-chamber, where the air and gas are commingled; hence I do not claim the same, broadly.
Having described my invention, I claim- 1. In a puddling or heating furnace, the combination, with a melting-chamber and a combustion-chamber, of a horizontal air-flue passin g beneath the melting-chamber and the combustion-chamber, vertical flues on each side of the latter, a vertical wall dividing said flues and having an opening on top of the combustion-chamber, whereby the air is caused to pass beneath the melting and combustion chambers, up on each side of the latter, over the top of the same, down on each side, finally emerging below the end of said combustionchamber, substantially as described.
2. In a puddling or heating furnace, the
combination, with melting-chamber A, combustion-chamber B, mixing-chamber E, and gas-burner G, of air-flue K, false bottom I, flue L, passing between said false bottom and the chamber A, wall M, intersecting the flue L, passages b b and b b at the side of the com: bustion-chamber, space 0 at the top thereof, connecting the passages 12 b with passages b b, and air-outlet D, all arranged and combined substantially as described.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
