PROVISIONAL SPECIFICATION.
Improvements in and relating to Coke-ovens with Recovery of the
Bye-products.
I, RUDOLPH BRUNCK, of Dortmund, Province of Westphalia, Kingdom of
Prussia, in the Empire of Germany, Doctor of Philosophy and Manufacturer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to coke-ovens with recovery of the bye-products, and
its object is to avoid losses of distillation gases which are due to the construction
of the ovens hitherto used.
In such ovens the connection between the coking chambers and the collecting
main has to be interrupted during the period of discharging and re-charging.
The considerable amount of gases and vapors evolved during the charging has
always been allowed to escape into the air-a nuisance to the workmen and to
the neighbourhood-(Figure 1). In order to avoid this loss, the oven is com-
bined with a special pipe collecting these gases and vapors and rendering them
available for use.
The improvement is shown in the accompanying drawing in which the oven
is traced as far as is necessary to clearly explain the invention.
Figure 1 is a view-partly in section-of one arrangement, while
Figure 2 is a similar view of another arrangement.
Figure 3 is a cross section through the collecting main and the oven.
In all the figures the reference letters indicate the same parts.

are the coking chambers connected with the collecting main c by
ascension pipes bbb. d is the above mentioned special collecting pipe,
which is disposed in Figure 1. below, in Figure 2 above the collecting main.
Tho ascension pipes can be connected with this special collecting pipe after
closing the entry of the gases into the collecting main. This communication
may be effected either by means of suitable tubes e, or by means of valves e¹.
The ascension tubes being connected with the above mentioned special pipe d,
the gases are drawn off through the flue f to the chimney, or into the conducting
pipe g, by means of a gas exhauster (not shown in the drawing).
The gases thus collected may be utilized as follows:
1. They may be employed directly (i.e. without extracting therefrom the bye-
products) for heating purposes, as raising steam; in this case they are drawn off
from the pipe d by the flue f.
2. They may be conducted through the pipe into a condensing plant and used
for the recovery of the bye-products; afterwards the gases are employed as
above described.
An important advantage of this improvement is that the gases are not allowed
to escape into the open air and cease to be a nuisance to the workmen and to
the neighbourhood.
