- nace Constructions, of which the following approved type,
is a specification.
The invention relates to furnace construc-v tions. The invention is illustrated as applied to a glass furnace but is applicable to regenerator furnaces employed for other purposes. It has for its primary objects, the provision of an improved arrangement of air and gas passages and ports, whereby (l) a better mixture of gas and air is secured than has been the case with the ordinary type of construction nowin use, (2)I lwherein increased economy in fuel consumption is secured, and (3) wherein a better color in the glass produced is secured, (where the invention is used iii/ia glass furnace) due to the better combustion of carbon which would otherwise tend to give an objectionable color to the glass. One embodiment of the inventionis illustrated in the accompanying drawings, wherein Figure l is a transverse section through a furnace having my improved arrangement of ports and passages; Fig. 2 is a section on the line II-II of Fig. l; and Fig. 3 is a section on the line III- III of Fig. 1. The furnace l (Fig. l) may be of any the form illustrated being designed to contain a body of'molten glass, and being known as a glass melting furnace. Itis customary in furnaces of this kind to provide regenerator lmeans on the" opposite sides of the furnace and alternate the How of gas the furnace, a series of ports beingprovided along the sides of the furnace, only one set of which are shown in the construction of Fig. 1. It will be understood that the ar rangements on the opposite sides of the furnace are the same so Athat a description of one side will. serve for both.A
Referring, for the'purpose ofv description, to the construction at the right-hand side of the furnace, 2'and 3 are regenerator chambers filled .with the usual checker work, not shown, the regenerator 2` being provided with a gas admission passage of the usual type. 4When the -ow-of gas is from the 'Furnace to the regenerators 2 and 3, the
and air back and forth across l regenerator 2 is of coursey connected to the outlet stack and the gas is cut off. The invention particularly relates t0 the arrangementl of ports and passages leading from the regenerators 2 and 3 to the furnace l.
The gas passage 4 is rectangular in cross section, as indicated in Figs. 2 and 3, and terminates in a port 5 which is short of the furnace 1. The air passage 6 from the regenerator 3 is also rectangular in\crosssec tion, as vindicated in Figs. 2 and 3,\`\and terminates at the port 7 which constitutes the combined outlet port of both the gas and air passage. It will be understood that the passages 4 and 5 may be cross-sections other than rectangular, if desired.`
The air passage 6 entirely surrounds the gas passage 4 and has an inclined upper portion, as indicated at 8, such inclined upper portion serving to contract the area of the air passage adjacent the end'of the gas passage. The same general result could of course e secured by inclining some other part or parts of the surrounding wall so as to give what'may be termed a nozzle effect.
The result secured by the foregoing arrangement is to provide a thorough mixing of the gas and air before the furnace is reached.
This gives a better combustion than the ar-v rangements heretofore employed, wherein one inlet passage was merely placed above the other. tirely surrounds the gas and the inclined upper wall 8 still further promotes the mixture since the gas and air are forced togethery through a restricted passage. The more perfect combustion which results from this arrangement not only gives better economy in fuel consumption, vbut in the case of a glass furnace, tends to secure a better color in the glass of the furnace. Any unburned carbon tends to color the glass and the improved combustion incident to the arrange.
ment of ports and passages practically eliminates any opportunity for such unconsumed carbon. Any carbon from the gas which is not completelyconsumed must fall through the ybody of air beneath, and th1s gives an opportunity for it to burn before it strikes the glass. Other advantages 1nc1- dent to the construction will be apparent to those skilled in the art.
What I claim is:
1. The combination with a furnace, the wall of which is provided with a restricted The body of incoming air en-' air and gas nozzle inlet, of a pair of regenerating chambers disposed adjacently of said wall, a o*as passage extending from one of said cham ers and provided wlth an outlet projecting inwardly toward and terminating short of said inlet, and an air conducting conduit leading from the other of said chambers to said inlet and disposed about said gas conduit to surround its outlet, the axes'of said outlet and inletl being located in dierent planes.
2. IThe combination with a furnace, the wall of which is provided with a 'restricted air and gas nozzle inlet, of a-pair of regenerating chambers disposed adj acently of said wall, a gas passage extending from one bers and connected with the wall of the fur-v nace about said inlet.
f3. rlhe combination with a furnace having a nozzle inlet, of regenerating means therefor comprising 'adjacently disposed inner and outer chambers, a gas conduit extending upwardly from said inner chamber and provided with an outlet projecting in- "wardly toward and adjacent to said inlet,
and an air conducting conduit leading from the outer chamber and disposed about said gas conduit, said last mentioned' conduit ter'-l minating at said'nozzle inlet and in advance of said outlet, the axis of said outlet being substantially co-incident with the top-line'of said inlet.
4. In .combination with a furnace provided with an inlet passage, of a pair of associated regenerating chambers, an air admission passage leading from one of said chambers and having its outlet end provided. with a wall portion downwardly inclined whereby to restrict said inlet passage, and a gas conducting conduit extending from the other of said chambers and having its outlet end disposed in the outlet end of said air admission passage and confronting said downwardly inclined wall portion, the body of said' conduit lying in the said air admissubstantially as described.
sion passage,
