Improvements in or relating to Coke-ovens.
A communication from FRANZ JOSEPH COLLIN, of Dortmund, in the Empire of
Germany, Engineer.
I, Alfred JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of the said invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:—
This invention relates to coke-ovens and will be best understood by reference to
the accompanying drawings in which ;-
Figure 1 is a section of the oven-wall on line c-d of Figure 2.
Figure 2 is a cross-section on line ab of Figure 3.
Figure 3 is a longitudinal section of the oven-wall on line c-d of Figure 2.
Figure 4 is a cross-section on line a-b of Figure 2, when double channels are
arranged.
Figure 5 is a longitudinal section of the oven-wall on line c--d of Figure 2, when
the vertical channels are divided.
In the arrangement of the channels according to Figure 1 the gases are led into
the horizontal channels f, whence they pass through the vertical channels g into the
sole channel h.
In the arrangement of channels according to Figure 3 the gases enter first the
upper horizontal channels i, whence they flow through the openings k into the
vertical channels and then through the orifices m into the lower horizontal
channel n, whence they pass with the gases, freshly introduced through the
orifices o, through the vertical channels p to the sole channel
g.
In the arrangement shown Figure 5 the vertical channels are divided by partition
walls into double flues.
In order to obtain a better utilisation of the gases in the gas ovens constructed
according to British Letters Patent No. 420593, in lieu of two flues C³, four
flues are provided and so arranged, that each gas current introduced passes through
without being divided. By this means every part of the side walls of the oven are
acted on by the gases (see Figure 5). Another advantage of this arrangement
consists in the great stability given to the walls of the oven, which is not obtained
by other constructions. Whether the oven serve only for manufacturing coke or
also for producing tar and ammonia, the admission of the gases may be controlled
as required by means of dampers.
To avoid frequent repairs resulting from the breaking of the covering plates
separating the horizontal wall channels, the horizontal channels in the side walls
are made shorter and the middle part of the walls is provided only with vertical
flues. Moreover the stability of the horizontal channels coming from both the ends
is considerably increased, if they are put in communication by means of vertical
heating chambers in lieu of by horizontal channels, so that there remain only an
upper and a lower horizontal wall channel, while the gases flowing through the
several vertical connecting flues for passing from one horizontal wall channel into
the other, are caused to flow through channels of equal length as they enter at the
outer end into one of the horizontal channels and How to the opposite end of the
other channel.
As for the production of bye-products the heating gas gives off a relatively short
flame, fresh gas is supplied on the passage to the vertical middle heating channels
as is the case in the arrangement provided only with horizontal wall channels (see
Figures 1 to 4). The gas may be conveyed first from the upper to the lower

page_text: horizontal wall channel or from the lower to the upper according as the mouth of
the middle vertical channels is below or above. The device may furthermore be
applied in partition walls having double or simple wall flues.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondent, and in what manner the
same is to be performed, I declare that what I claim is ;-
.
1. In coke ovens such as described in British Letters Patent No. 420593 the
arrangement of parallel flues such as C two by two one above the other and
passing separately without any partition through the wall of the oven so that the
'gases are mingled together only in the channels below the wall of the oven whereupon
they heat jointly the hearths of two adjacent ovens in combination with a damper
so arranged that with or without the production of bye-products the gas admission
into the lower end upper wall flues can be controlled at will substantially as
described and illustrated in the accompanying drawings.
2. In coke ovens the arrangement of horizontal and vertical wall flues in
such a manner that the middle part of the wall of the oven contains only vertical
channels while the two outer ends consist entirely of horizontal channels or each
end only of one upper and one lower horizontal channel connected with each other
by vertical heating chambers substantially as described and illustrated in the
accompanying drawings.
