CONSTRUCTION OF VERTICAL-CHAMBER OVENS.

Application filed December 17, 1920. Serial No. 431,469.

To all whom t may concern.'

Be it known that I, VVALTHER HIBY, a suby ject of the German Republic, residing at Scheveningen, Zeekant 55, the Netherlands,

have invented certain new and useful Improvements in the Construction of Vertical- Chamber Ovens, of which the Jfollowing is a specilication. f

The even heating of known vertical chamber ovens is very difficult, because the right distribution of heating gas and air for combustion is rarely obtained.

In the present invention the use of hori-- zontal iues in the' heating walls is abandoned and the combustion as well as the oliftake of the burnt-gases is solely done in vertical iiues. Only the long sides of the vertical chambers are heated. As shown on the drawing heating gas and air for combustion are led separated one from the other to the vertical heating lines by means of hori- Zontal canals, which are situated in the low er part of the heating wall. The regulation of heating gas and air is preferably 1done by means of dampers, arranged at the upper ends of the iues. In case all adjoining vertical iues would be heated directly and the burnt-gases be taken oli" from the upper part of the oven at one place only and led to the heat-exchangers (recuperators), the even heating over the total height of the chamber, would be impossible, as the temperature inthe long heating fines cannot be the same in their whole length. It on the other hand alternate burnt-gas tlues are built between the heating flues proper, then an exchange of heat occurs. The burnt-gas takes heat from the hottest parts of the adjoining directly heated lines and carries it to lesserheated parts of the chamber walls and an keven heating is assured. a

Figure 1 is a vertical section of the ovens passing thru a heating wall on line 1 1 ofV Fig. 2.

Fig. 2 is a transverse section thru heating walls and oven chambers on line 2 2 of Fig. l. Y

Fig. 3 is a horizontal section taken respectively on lines 3 3, 4 4, 5 5 and 6 6 of 50 Fig. l.

The invention is shown on the accompanying drawing in Figures l, Zand. 3, a are the vertical coking chambers with the interposed heating walls b. In the walls b are situated the directly heated flues c, which alternate with the double lues d for the 01T- talre of the burnt gases. The heating gas is led to the single lues c from pipe e by means of a branch pipe f and the horizontal canal g, from which it discharges through openings L into each iiue c. The air for combustion enters the heat-exchangers (recuperators) through openings c' into chambers 7c, passes through the same in upward direction in counter-current to the oheat, is collected in the canal Z, goes sideways to the heating wall, discharges through openings m and meets in -two streams the heating gas, streaming from openings 7L.

The lues c are, as described, heated directly, while the burnt-gas goes downward through the double lues d, to be collected in the canals a; it goes sideways to the heatexchangers, passes downward in the latter in double flues 0 in counter-current to the rising air and is led through opening p, regulated by a sliding damper r, to the chimney lines g rlfhe even heating of all iues c is effected by adjusting thefgas pressure in the pipe e and canaly g and by regulating the upper outlet openings of flues c by means of dampers s. The burnt-gas is evenly distributed to the flues 0 fot the heat-exchanger by means of regulating-dampers t.

Having now described my invention what I claim as new and desire to secure by Letters Patent is:

l. In a vertical chamber oven provided with flat sided vertical oven chambers with lilling openings at the top and discharge openings beneath the oven chambers, the combination of vertical heating walls outside of said oven chambers and extending lengthwise of the longitudinal axes of said chambers and on each of the long sides thereof, vertical heating liues in the heating walls, means for supplying gas and air for combustion to said heating flues, said means being located in the lower part ofthe heating walls, a plurality of vertical flues for the burnt gases arranged adjacent to the heating flues, the tops of the heating tlues and the inlet ends of the gas vtlues of a 'heating wall communicating with each lines of a li'eatll'gwell @one other, the discharge ports of the burnt gas Walls 'and leading to said fines, ineens for Supplying Fgas and 'air for eombustoiiiseparately to' Said Canals', a plurality of vvertical fluesfer the burnt gases arranged between the heat-ing fines, the tens oftlie heating fines" andf tlielinlet ends ofthe YLlnilrit gas fatina with ofthe burnt in" thelone parts ofthe each other, the diseliargeto gas fines' located ehernberfwalls so" to' vreturn"'the burnt geen .Santa-ts, @heersende an exchange of heat betweenV the heating ilues and the burnt gas flues.
