To all-'whom 'Zmcy concern: f

Be it known that I, LOUIS GEORGES FRO- ing at Liege, Bel iurn, have invented certain new and useful niprovements in Gas-Furto bea clear and-exact description of the inthe art to which it -use the same.

Gas furnaces and particularly regenerative gas furnaces used in the manufacture of zinc, as heretofore constructed, have been unsatisfactory because of the unequal distribution of heat through the various parts.

appertains to make and tion'are caused to travel alternately in oppoways divided into two .cl'1a1nbers, serving alternat'ely as` combustion and exhaust chambers, it hasl been necessary vto employ eX- tremely gatteo.' s coal which is expensive and difiicultto dlt-tain in many localities. These defects in furnaces of. thecharacter referred to as commonly constructed, are avoided by the present invention.

ln the accornpanying drawing, Figure 1 is a vertical section, on the line ll, oll l `ig. 2, through a furnace' in whichthe combustion. gases move horizontally and alternately in opposite directions, constructed in accordance withthe present invention; Fig. 2 is a horizontal section on the line A-A of Fig. 1 Fig. 3 is a vertical section through the furportion on the line (l-O of said figure; Fig. 4 is a vertical section on the line D-D of Fig. 1 Fig. 5 is a vertical section on the line J-J of Fig. 6, `through 4awreversing furnacev in Fig. 6 is a horizontal'section on the line lil-i of Fig. 5; Fig.7 is a vertical .sectional view, the left hand portion, thereof being on the line F-F of Fig. 5 and the right hand poi'- t'ion on the lineG-G of said figure Fig. 8 is* a vertical section on the line ll--fl of Fig. 5 ;4 Fig. 9 is a view on the line O-U ol' Fig. 1() siniilar to Figs. 1 and 5 through a non-reversing furnace in which the'con'lbustion gases move horizontally; Fig. 10 is a' horizontal section on the line Kr-h of Fig. 9 Fig. 1l is a vertical section through ,the furnace, the left hand portion thereof being on the line L-L of Fig. 9 and the right hand portion on the line M---M of Fig. 9; Fig. i2 is a sectional specification of Letters Patent. .Patented ocr. 13,' 190e.

view, Orr the line N--N of Fig; c; rig. 13 is a vertical section on jthe line. T-T .of Fig. 14

combustion gases move vertically; Fig. 14 is a horlzontal'sect-ion on the line P-P ofFig.

. through a non-reversing furnace in which the Y 1.3; Fig. 15 is a vertical section the left handI rated by a 'central partition in which are formed two sets of channels b, c, said-channels extending throughout the length of the furnace and having their outer endsv closed by sultable means. VThe channels e communicate with chambers m, z, of two regenerators, and the `channels b communicate respectively with similar chambers z', in said regenerators. The admission and direction of movement of air and gases from the regcnerators and through the furnace chambers and channels t, e, are controlled b v suitable valves'represented at 1, 2, in'- l1`igs.2 and 6 in the ordinary manner.

The retorts a are preferably arranged 'iny the furnace chambers in the manner illustrated, being grouped in pairs and supported Asubstantially horizontal. feaclr group or pairs are separatedfby adistance of three t`o four centimeters and the groups 1 n the same horizontal `plane,.are

The retolats of separated from each other by a space of thirteen to fourteen centimeters. Such separation of the groups of retortsis necessary 1n y order that the refractory plates on which the retorts rest maybe properly supported vby refractory` pillars.

The pillars supporting the retorts form a series of. dead spaces between the several groups of retorts, which spaces have heretofore not been'em-ployed 1n heating the furnace.

The retorts 'in one horizontalplane aresepf araterl from those above and below them by y a distance of fourteen centimeters, which separation is necessary in order that the retort supl'iortlng projections on -the central wall between the furnace chambers may be sufliciently strong to bear the weight placed thereon. This -separatio Jtends to for-m a series of dead spaces lietween the different rows or layers of retorts, These dead s aces fox-ined in the furnace chambers 41S a ove described, and which have heretofore l not been utilized, are,

tion, made effective as t ings connecting the air and gas channels with the furnace chambers are caused to open into the said chambers through said dead spacesff i t In the furnace illustrated in Figs. 1 to 4 l and 9 to 12, the inlet apertures orburners are arranged in the horizontal dead spaces m,

each consisting of two apertures o, w, cornof gas and au which enter the furnace chamber through any burner will be immediately and intimately mixed lWithout the employment of an obstacle in the path of such currents lto e ect such miXil In theform of furnaceizllustrated in Figs. 5 to 8 and 13 to 16in"whch. the combustion gases move .vertically through the furnace, each burneralso inc udes two orices i, y', which are arranged 1n the vertical ,"dead spaces n 'and communicate respectively with the iiues or channels e, b. The relative arrangement of the -burner openings fi, j, it will be seen is the same as that of the openings c, fw, previously described.

.ln the reversing furnace illustrated in Figs. 1 to 8, it will be understood that the gas and air are alternately admitted through the burners adjacent one end of the furnace and withdrawn or escapes through the corresponding burner openings adjacent the opposite end of the furnace. For example, and referring to Fig. 1, if gas is supplied to the regenerator :I: it will enter the furnace chambers through the channels or flues b and the burner openings o and air will enter said chambers from the rcgenerator and' through the Aflues or channels e and-the openings w. The products of combustion will pass from the furnace chambers through the openings fn, w, at the right -hand side of the furnace and the flues or channels b, c, into the regenerators z, z. In thistype of furnace the combustion llames pass horizon.

tally and by properly -adjusting suitable valves the direction. of movement of the gases and air may be reversed. That is, the rcgencraters 2, z may serve to supply gas and air to the furnace while the chambers w, receive the products of combustion instead of the latter supplying the air and gas as before described.

ln the continuous furnace illustrated in Figs. Si to 16 .the gas andair is constantly supplied through the burners and the products of combustion pass from the furnace or l escape through orifices /f' andflues c (iu the vertical combustion furnace illust ruled 'in Figs. lil to lo) or byorilices at the extreimthe present invene passages or open seeehr ties of the furnace in the'horizontal combus'" tion furnace illustrated in Figs. 9 to 12.

Among the/advantages possessed by a furnaceJ constructed as herembefore described and illustrated in the drawings may be noted that as the gas and air are admitted to the furnace at numerous points and throughout the entire height and length ofthe furnace chambers, complete combustion and equable diffusion of heat are effected throughout the entire furnace. As the combustion takes place in free spaces between the retorts, it is more complete and advantageous than when effected in the manner heretofore commonlyfollowed. i/Vith such afurnace it is possible to employ combustibles which arelrelatively oor 1n .volatile constituents, because the ength or extent offlame is reduced to a minimum and also thc maximum amount of space Within the furnace is employed.

'lhc invention may he embodied in nonintermittent recu eration furnaces for heating the air as wel as for reversible regenerator furnaces for heating air and gas or only heating air and may also be employed in furnaces which are not provided with regenerators or i'ecuperatois. It may also be ern-4 ployod in reversible rcgenerator furnaces in 'which the reversal takes place round an imaginary vertical axis of g'vration, or round an imaginary horizontal axis of gyration. lndee( reversal round an imaginary horizontal axis can only be effected by the means herein described,

By the invention it is possible to construct furnaces of maximum size in which there will bc an equable' diversion. of heat throughout the entire length and height of the furnace and a material economy of labor sumption of fuel'ieffected.

By providing an cquahle temperature throughout the furnace the duration of life of the furnace, as well as the retorts, mufiics,

)ots or cruciblcs containing the material to be treated, is materially increased.

Having thus described the invention what and conis claimed and desired to be secured by hetn ters-Patent is, 1. A gas furnace having a plurality of retorts therein and having burners arranged in the spaces between the retorts, each burner consisting of two orifices which extend laterally from and respectively communicate at their outer ends with air and gas channels,
