Application filed. May G,
or .e like, and particularly to improvements in the arran ments disclosed in my prior Patent No. 1,2063028, granted June @ne ol the objects ol" present invention is to provino nring system of the e continuonsAl'eruperating highy cliicient, particnlrofly in connection with the hea-t interchange between the incoiniio' air and the outgoing waste gases.
[n her object of my invention is to proride an arrangement by whichthe air supplied to the various heating chambers in a set of ovens will be nniformlj,7 heated so that there will be substantially no ineqnaliq7 in the temperature of the air supplied to the several heating chambers.
tipe which will be n l ll-fith these and other objects in view, my
invention consists of the novel arrangement of parts herein described and pointed out in the appended claims.
ln the drawings, Figure l is a vertical section of a portion of a set of ovens embodying my .invention7 the portion of Fie'. l to the lett of the line :fibeing taken on the l` e ril-Ar ot F 2,v and the portion to the lit ot the line m--fc being taken on the line of Fig. 2; Fig. 2 is a vertical section taken on the line 2-2 of Fig. l; Fig. 3 is a section taken on the line 3-3 of Fig. 2 looking from below; F 4f is a detail.
rl"he corresponding' parts are referred to mth in the specification and in the drawings similar reference characters.
ln the illustrative form of my invention., lt is one ot the ovens which may be charged from openings above, in the usual manner. ./ldjacent the walls of the oven l0 are a series or combustion chambers l1., each provided with a burner l2 connected to any suitable source of supply of fuel, which in this instance is gas.
lnterposed between the combustion cham- Vbers ll are air ducts 13 communicating at i l l nate vertical ducts ot the reci;

the top with the coinbnstiza chamocrs l 'fa-cent the burners the.. ein.
leneath the floor ofi the oven l() is a horiz ntal duct rommel with the combustion chambers ll, through the ducts l5, to receive the waste gases Jrom the combustion chambers.
Extending); horizontally beneath the seriel ol combustion chambers and verti al ducts 13 are horizontal air ducts l which the lower end ot each ot one series olf air ducts lil fomnninicates.
Beneath the ducts and l@ is a continuous recnperator made np oit' a series el" vertical ducts of relativelyv small cross section the ducts l? communicating directly with the horizontal wir ducts 1G, and the ducts lr communicating' with ie horizontal air duct," l5 by oblique ducts 20, zn l the ducts l) communicatingthrough the oncts2l lter @gator connected to the wastegras horizontal duct le, the ducts 22 communicating directly e: :l the ducts lil, and the ducts coinmnnican ing through bliqne ducts 241y and t ducts 25 communicating throue'h the oblique the ducts 26.
Similarly, the lower end of the veroical ducts or' the recuperator, which are connected to the horizontal air ducts 167 are also connected to horizontal air inlet ducts 28, and the lower ends ofthe waste ducts or" the recuperator, which connected to the horizontal waste gas ducts le? are connected to the horizontal waste ducts 27.
Preferably, l malte up the vertical ducts ot the recnperator by means oi special brick 30, a detail ot which is shown in Fig. 4l. As shown, this briclr is substantialljT l..- 'shaped with a recess 3l at one end adapted to have litted into it the oA po, ite end of one of the bricks 30. Preferably, the brir-lr is grooved, as at 32. to receive a corresponding tongue on the bottom of the next adjacent brick. As shown beet in Fie'. El., with this one form of brick am enabled to build np a series or" vertical ducts which are interloclred so as to provide a substantial snpport *for the oven structure above. Trofei.'- ably, the whole structure for the recuperator is made independent of the side walls olf the kiln so as to permit expansion and contraction without injrirj7 to the supportingv structure.
.ln operation, air is supplied through the ducts 28 to the vertical ducts 17, 18 and 19 of the recuperator, the walls of which are heated by the waste gases coming from the combustion chamber 11 in the manner hereinafter described. The heated air passes to the horizontal ducts 16 by which itis distributedv to the several vertical air ducts 13 between the respective combustion chambers, and from thence the air passes into the combustion chamber vadjacent the burners. The burnt gases pass downward in the combustion chambers 11 through the ducts 15V into the horizontal ducts 14, by which it is distributed to the several vertical, waste gas ducts 22, 23 and 25 of the recuperator and from thence to the horizontal waste gas ducts 2'?. i As the heated gases pass through the recuperator, the walls thereof are heated and this heat is transmitted to the air passing upwardly in the corresponding air duets.
As will be seen by an inspection, particularly of Fig. 1, by my present arrangement l provide a means by which a multiple effeet may be obtained from the gases passing through the recuperator, these gases being siib-divided in their passage, so that to a maximum degree the incoming air and the outgoing gases are brought substantially side by side, so that t-he heat from the one may be more readily transmitted to. the other. By my arrangement of ducts 1 have also provided a means by which the incoining air supplied to any combustion chamber receives. its heat, not only 'from the immediate combustion chamber with which such air duct cooperates, but also from lcoinbustion chambers of adjacent ovens. The heating of the air is thereby equalized so that substantially uniform conditions will prevail throughout a given set of ovens. More-` over, by supplying vthe air from the recuperator to the horizontall air ducts, there is a further equalization or' the supply et heated air to the several combustion chambers- 1 claim: v Y
1. A horizontal oven, a series of vertical combustion chambers adjacent the side wall of the oven, a burner at the upper end of each combustion chamber, a series of vertical aii ducts adjacent the side wall of the oven, leach air duct being. located between a pair of the combustion chambers and coinmunicating with the upper end oaf one of the combustion chambers, a horizontal waste gas flue extending beneath the floor of the oven and communicating with the lower ends of the combustion chambers, a`horizontal air duetV beneath the lower ends of the combustion chambers and communicating with the lower ends of the vertical air ducts, and a recuperator located beneath said horizontal liues, and comprising a plurality of vertical ducts, each relatively high and narrow in cross section, a plurality of alternate ducts of said recuperator croisswise of the axis of the oven being connected to said horizontal air duct and the remaining ducts of said recuperator being connected to said horizontal iwaste gas flue.
2. A plurality of horizontal ovens spaced apart, a series of vertical combustion chambers between each pair of ovens, a burner at the upper end of each combustion chamber, a series of vertical air ducts between each pair of ovens, each air duct being located between a pair of the combustion chambers, and communicating with the upper end of one of said chambers, a plurality of horizontal waste gas lines and a plurality of horizontal air ducts beneath the level oi' `the floors of the ovens, each horizontal. waste gas flue being located between a pair of horizontal air ducts, and communicating with the lower ends of one series of combustionV chambers, the lower ends oit the corresponding series of vertical air ducts communicat ing with the adjacent horizontal air duct,
. and a recuperator located beneath said horizontal ducts and flues comprising a plurality or vertical ducts, each relatively high and narrow in cross section,.there being at least four times as many of suchducts in. a plane at right angles toi the axes of the ovens as there are ovens, a plurality of alternate ducts of said recuperator.-crosswvise of ,theY
axes oit the ovens being connected to each` of said horizontal waste gas flues and a Vplurality of the remainingducts being connected to each of said horizontal air ducts.
