FLATTENING-OVEN FURNACE.
Patented May 17, 1921.
Application filed. May 7, 1918, Serial No. 233,905. Renewed October 9,1920. ,Serial No. 415,949.
To all whom it may concern:
Be it known that I, HENRY F. CLARK, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Flatte-ning- Oven Furnaces, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a sectional plan view of a flattening-oven and furnace embodying my invention, and
Figs. 2 and 3 are sections taken on the lines TT--II and TIL-III, respectively, of Fig. 1.
Figs. 4c and 5 are sectional views showing a modification.
My invention has relation to improvements in flattening-oven furnaces, and more particularly to gas-fired furnaces of this character. My invention is designed to provide means whereby a more perfect combustion may be obtained and the efficiency of the furnace greatly increased. My invention also provides means whereby the furnace, although regularly adapted to operate with producer gas, may, without interruption, be made to operate on natural or other gas, or upon fuel oil.
The nature of my invention will be best understood by reference to the accompanydrawing in which I have shown a preferred embodiment thereof, it being premised, however, that various changes can be made in the details of construction, arrangement and combination of the parts without departing from the spirit and scope of my invention, as defined in the appended claims.
.l'n these drawings, the numeral 2 designates the usual rotary flattening table, 3 the flattening stones thereon, 4 the shove-in opening for the cylinders to be flattened and 5 the outlet passage leading to the annealing leer. These parts, together with the general construction of the oven, may be of any usual or suitable construction. 7
6 designates a gas main leadin from a gas producer and having the brane 7 which supplies the flattening oven, this branch having the port 8 controlled by a suitable valve 9. The flue 7 has an outlet opening 10 which leads into the nozzle shaped re fractory member 11. This member, in turn, discharges into the mixing and initial combustion chamber 12, the latter extending upwardly on one side of the shove-in passage t and thence laterally above said passage and into the flattening oven proper.
The nozzle mem er 11 extends vertically through an air chamber 13 which is provided with a suitable air inlet, such as shown at it; and terminates within an opening 15 in the floor of the chamber 12; said opening being of sufficiently larger diameterthan the nozzle to provide a surrounding air passage.
with any suitable regulating damper or valve. In the construction shown, this opening leads from a vestibule 16 having an air The air inlet opening 14 may be provided inlet opening at one side, which is 0011- producer supplying the main 6w This additional gas supply may be natural where that is available, or fuel oil may be employed in these burners.
The operation will be readily understood. The producer gas is discharged into the mixing and primary combustion chamber 12 through the nozzle 11, the latter having an injector action whereby air is drawn into the chamber 12 through the opening 15. The result is that a proper amount of air is supplied and becomes thoroughly mixed with the as in passing through the mixing and primary combustion chamber.
If, for any reason, the supply of, producer gas should vary at any time, gas may be turned on at the burner pipes 18 and the latter used for the continued operation of the furnace, thereby avoiding interruptions or shut-downs until such time as the supply of producer gas again becomes available.
The actual commercial operation of flattoning-ovens embodying my invention has demonstrated the greatly improved character of the combustion obtained and the use of the invention has been found to greatly increase the efliciency ovens.
It will be readily understood that as many of the nozzle members 11 may be used as ma be desired in any particular case.
g1 Figs. 4 and 5 I have shown a modification in which an air-supply nozzle 11 is placed within the gas nozzle 11, so that a portion of air for combustion is drawn in through said nozzle 11 and another portion through the opening 15 If desired, however, all the air may be supplied through the inner nozzle.
I claim 1. A glass flattening oven having a flattening chamber, a shove-in opening at one side of such chamber, a combustion chamber at the outer side of the shove-in opening, an air chamber below the floor of the combustion chamber, a gas chamber or passage below the floor of the air chamber, the floors of the combustion and air chambers having vertically alined openings therein, and a tube extending vertically through the air cha iber and connecting the said openings, said tube having an upwardly converging interior passage, and there being a. space around that portion of said tube within the opening or the floor of the combustion chamher through which air from the air chamber can pass into the combustion chamber; substantially as described.
2. A glass flattening oven having a flattening chamber, a shove-in opening at one side of such chamber, a combustion chamber at the outer side of the shove-in opening, an air chamber below the floor of the combustion chamber, a gas chamber or passage be low the floor oi the air chamber, the floors or" the combustion and air chambers having vertically allned openings therein, and a tube extending vertically through the air chamber and connecting the said openings, said tube having an upwardly converging interior passage, and there being a space around that portion of said tube within the opening of the floor ot the combustion chamber through which air from the air chamber can pass into the combustion chamber, said tube having therein an air supply pipe provided with means for the admission of air thereto; substantially as described.
3. A glass flattening oven having a primary combustion chamber, a gas supply nozzle communicating with said chamber, and an auxiliary burner also opening into said chamber at a point closely adjacent to the gas supply nozzle and which is connected to a different source of fuel supply from that which feeds the said nozzle; substantially as described.
4. A glass flattening oven having a mixing and primary combustion chamber at one side of the oven proper, a gas supply flue below said chamber, an air chamber intermediate the gas supply flue and the primary combustion chamber, and a nozzle member communicating with the flue and arranged to discharge into the mixing and primary combustion chamber, there being an air opening leading through the floor oi"- the combustion and mixing chamber, and a burner having another source of supply and also arranged to discharge into said mixing and combustion chamber; substantially as described.
In testimony whereof Ihave hereunto set my hand.
HENRY F. CLARK.
