C. OTTO COKE OVEN Filed Jan. 20, 1928 INVENTOR CMX @M Patented May 27, `1930 UNITED STATES CARL OTTO, F ESSEN-BURR, GERMANY COKE AOVEN' Application filed* January 20, 1928, Serial No. 248,285, and in Germany November 16, 1928.
The invention relates to coke ovens, particularly to those havin gated coking chambers t e heating walls of which are subdivided so as to form vertical hairpin iiues. A
With chamber ovens of this type the brickwork of the heating walls must be able to support the entire weight of the oven coverI chamber, the so-called running walls, and of partitions arranged normally transverse thereto, the so-called binding walls, which subdivide the heating walls into the individual heating fines. This brickwork, composed of the runningl and binding walls, of the heating walls must thus be able to support the above-mentioned load and must therefore have a corresponding total sectional area.
Now m invention is based upon the perception o the subdivision of the heating lues into vertical twin lues affording the possibility to take'up by said so-called binding walls the entire load of the oven cover including the weights resting thereon, and to thus completely discharge the so-called running walls from the load.
For, as with the arrangement of twin lues each alternate or second binding Wall extends throughout the entire height of the heating wall, series of piers or columns may be established within the heating iiues by suitably diminishing the sectional area of the binding 4b walls, which piers are able to support the weights entering into consideration.
.Referring to the drawings:
Figure 1 is a vertical section ofa coke oven on the line 1-1 of Figure 3, showing the decreased thiclmess of the running walls.
Figure 2, is a longitudinal section on the line 2` 2 of Figure 3, and shows the greater thickness of the binder walls with relation to the running walls of Fig. 1.
Figure 3, is a horizontal section showing horizontally elon- 4each pair of runner walls. The binder walls are spaced apart in the direction of the oven chamber, and each alternate binding wall of the series extends vertically to the oven cover (5). The binder walls thus provide vertical hairpin nues (4) which extend in a single row. in the direction of the chambers. v
Now, according to my invention and as shown by the drawing, the running walls 1 freed in this way from this load, may be made much weaker than hitherto usual, as they must only have a minimum thickness that depends on the structure itself and on the required resistibility to the stresses occurring for examplewhen the coke cakes are pushed out of the chambers. As the running walls have to'form at the same time a gas-tight 35 partition between oven chamber and heating filles, the individual running wall bricks have groove and feather joints, in order'to avoid straight oints, as the danger of mutual transsitions of gas taking place is naturally much greater withstraight joints than with bent. joints. This configuration, however, 'of the bricksl having groove and feather joints, of itselr` provides a minimum thickness of the f' running walls for construction reasons, this thickness in practice being not less than 65 mm. This thickness is quite suicient to take up the stresses occurring upon pushing the coke cakes; Of course, account has to be taken of the height of the heating wall. Generally a somewhat greater thickness of the .running wall bricks will be provided for with increasing height of the heating wall.
Furthermore account has to be taken of the material -of the bricks for the binding and running walls, in particular of the point of fusion of the material. The above-mentioned minimum thickness of 65 mm. holds good of a medium oven height and best silica material having a fusion point lying far above 1550 10 I o ed in the chamber oven, this additional stress of the bricks of the running and binding walls must be compensated for by a pard 1lgrecs C. In case a very windy coal is to be c 5 ticularly careful selection of the stone bond of the chamber, the great economical impor- `/tance of the invention is evident, as it not only permits of a large quantity of bricks to be saved, but also of the carbonizing period to be notably shortened.
In contradistinction to the decreased runner wall thiclmess of 65 to 100 mm. to be employed in accordance with my invention (see Figures 1 and 3), the former Wall thicknesses of the running walls even of low ovens 1 were generally 130 to 150 mm. and only in specia cases 120 mm. Hence afsaving of '25 bricks of nearly 50 per cent is obtained by my invention.
Althou h the binding walls have to take up accor ing to my invention the entire weight of the oven cover and the load rest- 3'0 ing thereon, their thickness generally needs not to be increased, in comparison with the thickness hitherto employed of 130-150 mm. Experience has proved that such, a thickness of the binding wall bricks 2 will serve for the practical realization of my invention.
Walls of this thickness have been employed and have even been surpassed in many cases to a considerable extent. This at first sight surprising feature is due to the fact, that the greater part of the former chamber ovens were provided with a horizontal heating passage extending above all the heating flues, and that the binding walls separating the individual heating flutes thus did not extend up to the oven cover and'thus had to take up only indirectly, through the somewhat projecting running wall bricks that surround said horizontal passage, a certain fraction of the load of the cover 5. By my invention each alternate binding wall 2, extends throughout the, entire 'hei ht of the oven wall to the oven cover (see igure 2).
Each alternate binding wall thus acts as a supporting column for su porting thel load of the cover 5. The binding walls always serve as struts for the running walls against the/ pressures exerted from t e oven chambers and must be made rather thick for this purpose. According to the invention this property of the binding walls is fully utilized by a suitable stone bond, and the running wall bricks are discharged as far' as possible from this load also. v
What I claim and desire to secure by Letters Patent is 1. In a coke oven havin l a row of alternate horizontally elongate oven chambers and parallel heatingwalls therefor arran ed side by side, andl an oven cover there or,
each of said heating walls comprising a pair.,
of separated runner Walls running in thedir rection of the oven chambers, and a series of parallel faced transverse binder walls extending between each of the pairs of runner walls, the binder walls in each of said series being spaced apart in the direction of the chambers, the alternate. binder walls in each ofsaid series extending vertically to the oven cover, and 'theintermediate binder w'alls extending to a lesser height providing vertical hairpin lines extending in a row in the direction of the chambers, the binder walls forming the two end faces of the flues; said alternate binder walls consti-.
tuting supporting columns and being of material y greater thickness than the maximum thickness of the runner walls, so as to su port the major part of the weight of t e cover and loads resting thereon, and enabling the thickness of the runner walls to be decreased to permit uick transmission of heat, the thickness of t e runner walls being bers, the alternate binder walls in each of said series extending vertically to the oven cover, and the intermediate binder walls extending to a lesser height, providing vertical hairpin lues extending in a row in the direction of the chambers, the binder walls forming the two end faces of the lues; said alternate binder walls constitutin supporting columns and being one and a' alf to twice -as thick'as the maximum thickness ofthe runner walls, so as to support the major part of the weight of the cover and loads resting thereon, and enabling the thickness of the runner walls to be decreased to ermit uick transmission of heat, the thic ess ol v the runner walls bein suiiicient to resist transverse stresses pro uced in coke pushing.
Intestimony whereof, I have signed my name to this specication.
CARL OTTO.
