lThis invention is for an y. improvement in' glass furnaces, andr more especially the smaller types ofcontinuousfurnaces adapted forspecial smallibatche's of 'glasslV andin# tended primarily tolreplace day tanks now commonly used. s f
. In continuousy furnaces of `thetype referred to, the furnaceis divided intermediate its length by a bridge wall so as tov form a melting chamber and a vworking chamber. Heat is provided Aby, burners located at the chargingv end of the melting chamber and a flueto recuperators is provided at the top of the furnace. at the working end of the l5 chamber through which the products of `combustion are removed. L
Considerable difficulty has been encoulr` tered in the use of these tanks, the circula* tion of allof ther/products of combustion comingdirectly overthe glass inthe working end of the chamber, and to this end. my invention proposes to provide for the protection of the working chamber while maintaining proper working temperatures f therein. The nature of the invention may be readily understood by reference to the accompanying drawings, which illustrate one embodiment of. my invention, and in which:
Figure 1 represents a longitudinal vertical section through a` furnace embodying .my invention. y' 'Y Figure 2 represents al transverse section in the plane of line II-II'of Figurey l. In the drawings, 2 designates the interior of a small furnace of the continuous type having a bottom 3, side walls 4, a top 5 which is preferably arched, a front or working end wall 6, anda rear or charging end wall 7. A charging opening of the usual type is provided in or adjacent the rear wall 7 .l The interior` ofthe furnace is divided intermediate itsends, and preferably ata point slightly past the middle towardA its front wall 6, by a bridge wall 8 of less height than the interior of the furnace sothat a gas circulating passage exists above this wall. Threats 9 are provided in the bridge wall adjacent the bottom.
The function of the bridge wall is to divide the interior of the furnace chamber below the desired level into a melting chamber l0 where the raw materials are melted as they fiovv toward the bridge wall and a or more burners are provided `in the' rear vwall 7, the holes for the burners being desig' nated 14. The products of combustion are removed from the interior of the furnace through a flue or stack opening` l'at the lworking end of the furnace. These in usual practice, are delivered toa recuperator atv this point. .h
n order to protect the glassy in the worin ing chamber, ll, I propose, according to the present invention, to provide, a closed Vre-` fractory arch 16 over ther working chamber and extending from the bridge wall tothe forward or working end wall 6 of the furnace. This arch, in effect, provides a mufn fle or circulating passage outside the Workingchamber by means ofr which a high temperature can `be ,maintained in the working chamber. without directly subjecting' the glass Ainr the chamber to the gases of combustion. This valso prevents the gases ofl combustion from escaping'through the working doors, and prevents vinterference with the circulation ofthe gases of combustionf by reason of air entering the working doors.
If necessary, auxiliary burners can be provided for the working end of the chamberunder the muffle wall or arch 16, ports for these burners being indicated at 17. These local or auxiliary burners provide fiexibilitygof temperature control and adiustmentof temperatures to meet local conditions while avoiding, the necessity for the entire mass of the products of combustion from flowing over the glass in the working chamber as has heretofore been the practice. K The advantagesof the present invention have already been indicated, these advantages i arising from the provision of L the archedmuffle-tile wall 16 and the provision of the burner passages 17.
While I have illustrated and described one preferred embodiment of my invention, it will be understood that the invention may be otherwise embodied and that various changes and modifications may 'be made therein within lthe contemplation of my inventionl p and under the scope of the` appended claims.
