-PUDl3LlNG-FURNACE.
SPECIFICATION forming part of Letters Patent No. 270,184, dated January 2, 1883.
Application filed February I5, 1882. (No model.) i
and exact description thereof.
My invention relates to an improvement in t that class of puddling-furnaces in which hydrocarbon gas is used as fuel; and it consists in the arrangement and construction of the interior of the furnace for the purpose of obtaining a thorough and perfect combustion of the gas, so as to create an intense heat over the hearth of the furnace.
My invention is described as applied more especially to puddling-furnaces; but it may be adapted to heating and other furnaces.
I will now describe my invention, so that others skilled in the art may manufacture and use the same, reference being had to the accompanyingdrawings,forming a part of this speci- -lioatio n,'in whieh--- Figure 1 is a vertical longitudinal section of my improved paddling furnace. Fig. 2 is a detailed sectional view of the vertical wall h and perforated gas supply pipe embedded therein. V
Like letters refer to like parts wherever they occur.
In the drawings, (t represents an air-flue which extends from the front to the rear end of the furnace. Above the fine a is another fine, (I, which extends along and under the hearth 0, being separated from the flue a by the division-wall or false bottom I), to the front end of the furnace, where it opens intothe fluef.
. The lines a and d communicate with each other a gas supply pipe, 70, having perforations extending its length,.which discharge into the space. The wall h should be somewhat higher than the wall g. Beyond the wall h is a dependent wall 1, extending downward into the chamt her 1 from the top of the furnace. The bridgewall m divides the chamber 1 from the hearth e. The operation is as follows: The inflowing l, which deflects the gas and air downward into the chamber-,1, where a low combustion takes place and the gas and air become mingled, so that they burn with a clear flame, giw
ing out intense heat over the hearthe, where they are entirely consumed, and merely the products of combustion pass out through the neck and stack, the destruction of which by hot flames is'thereby avoided.
The advantages of my invention are: First, the air is thoroughly heated before coming into contact with the gas, which renders the combustion more perfect; second, the gas escaping from the opening 0, which extends across the furnace, becomes heated byand thoroughly mingled with the heated air; third, the wall It, pendent wall 70, and bridge-wall m retard the flow of the air and gas and cause them to be thoroughly mingled, so that the combustion over the hearth e is complete, and an intense heat is created at that point; and, fourth, the
' combustion over the hearth being complete, or
nearly-so, the,neck of the furnace is not apt to burn out, as heretofore.
I am aware that heretofore, in the construction of this class of furnaces, false bottoms have been used to form return-fines for heating the incoming air; that vertical walls have been used to divide the COIllbl'lSlllOlbClJ-dlllbl into principal and auxiliary combustion-chamhers; that perforated pipes have been used to deliver the incoming combustible gases; and
that-generally the several elements are not novel per 86, min combinations of two or more; i
but I am not aware that the several elements have been heretofore arranged to enact, as herein set forth and claimed and therefore,
Having thus described my invention, what I claim, and desire to secure by Letters Patent,
1. In a gas furnace, the combination, with the working-chamber, of a false bottom or di- IOU visiorrwall arranged below the same to form I of air, substantially as and for the purpose a return-flue for the admission of air, a vertical Wall for forming an auxiliary combustionchamber in front of the working-chamber, and
5 a perforated gas-supply pipe arranged to deliver into the air-flue, substantially as and for the purpose specified.
2. In a gas-furnace, the combination, with the working-chamber, of a vertical wall which formsan auxiliarycombustion-chamber,apendent deflectingwall arranged over the auxiliary combustion-chamber. a perforated gassupply pipe, and a division-wall or false bottom arranged below the working-chamber or hearth to form a return-flue for the admission specified. I 3. In a gas-furnace, the combination, with the working -chamber, of the pendent wall I, the vertical walls g h, perforated gas supply pipe k, and false bottom I). the parts relatively arranged to form thereturn-flue a d, fluef, and auxiliary com bustion-chamber 1/, substantially as and for the purpose specified.
In testimony whereof I have hereunto set my hand thislOth day of February. A D. 1882. JOHN EVANS. Witnesses:
JAMES K. BAKEWELL, L. (3. FITLER.
