Improvements in Coke Ovens.
I, GUSTAV HILGENSTOCK, of Dahlhausen on the Ruhr, in the German Empire
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to the manufacture of coke generally, but more par-
ticularly to that of long grained coke, in bee-hive ovens, and especially to means
of preventing the decomposition of the by-products during the coking of the coal,
so that they may be recovered for use. For this purpose, the coke ovens are made
with a broad flat base and little height, and in the brick foundations flues are
constructed which extend under the bottoms of the ovens and aid in the heating
of them from below.
The gaseous fuel is led into these flues through. nozzles which are in com-
munication with a duct below, each duct being situated in a passage.
By these passages the ducts and the nozzles are easily accessible. Some forms
of my improved coke oven are shewn in the accompanying drawings in which
Fig. 1 is a vertical section, the two left compartments having flues as shewn in
the upper half of Fig. 3, the right compartment having flues as shewn in the lower
half of Fig. 3.
Fig. 2 is a vertical section, the right half on the line C D and the left half on
the line A B of Fig. 3.
Fig. 3 is a plan the upper and lower halves of which shew two arrangements of
the flues under the bottoms of the ovens as will be described hereafter. Fig. 6
is a plan shewing in its upper and lower halves two other arrangements of the
flues.
Fig. 4 is a vertical section, the left half having flues as shewn in the upper half
of Fig. 6, the right half having flues as shewn in the lower half of Fig. 6.
The right half of Fig. 5 is a vertical section on the line CD of Fig. 6 and the
left half of Fig. 5 is a vertical section on the line A B of Figure 6. In Figs. 1, 2, 4
and 5.a a are the coking chambers of the beehive coke ovens, b, b are charging
openings and c, e the outlet pipes for the gases. d, d are the bottom flues, the
different arrangements of which are shewn in Figs. 3 and 6. e, e Figs. 1, 2, 4.
and 5 are the gas ducts from which the burner nozzles f, f are supplied.
These nozzles open into the flues d, as shewn in Figs. 1 and 4.
In the upper half of Fig. 3 an arrangement is shewn in which the gaseous
fuel issuing from the nozzles f on the gas pipes e enters flues which are parallel to
but separate from, each other. Before reaching the damper g of the chimney
flue (Figs. 2 and 3) the two currents commingle and pass together into the chimney
flue 'h.
In Fig. 2 the flue is shewn in section, in Fig. 3 however it is indicated by dotted
lines.
The lower half of Fig. 3, shews an arrangement of two exit flues at the
sides (2, 2) which both discharge into the chimney flue h and each of which is
controlled by a damper g.
The flues & and d₁ open alternately into the flues i 2.

of the heating gases is indicated by arrows.
The course
The openings (Figs. 1 and 4) in the arches of the ovens serve for the warming
of the oven being in communication with the flues below through vertical flues m, m
in the oven walls; the flues m can be cut off from the ovens by the dampers n n.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is:-
Flat bottomed coke ovens heated by means of burner nozzles opening into flues
in the masonry foundations of the ovens.
