I, GUSTAV HILGENSTOCK, of Dahlhausen, Germany, Engineer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to a construction of coke ovens in which the supply
conduits for the gaseous fuel enter the combustion chambers or flues from below,
and are so arranged in passages formed in the substructure of the oven of sufficient
size for persons to enter then that the said gas conduit shall be accessible at all
points, and that consequently the supply of combustible and the consequent heat
of the fire in the oven can be accurately regulated by suitably arranged valves.
The invention therefore only relates to the substructure of the coke oven and
to the conduit for the gaseous fuel contained therein, while the construction of the
oven proper and that of the heating flues of the coking chambers &c. may be of
any suitable known arrangement.
The said passages and gas conduits may be arranged in a variety of ways for
the purposes of this invention; thus according to one arrangement, a central
longitudinal passage is arranged in the substructure below the coke oven from
which lateral passages branch off on each side, there being one such passage under
each coking chamber.
The main gas supply conduit runs along the central main passage, and from this
conduit lateral branch conduits extend into each lateral branch passage, where
such branch conduits have other branches extending up to nozzles in the bottoms
of the heating flues on each side of each coking chamber.
According to another arrangement there are a number of longitudinal passages
running under all the coking chambers and each containing a gas supply conduit,
from which lateral branches rise to nozzles contained in the heating flues of the
chambers.
According to another arrangement the main gas supply conduit is contained in
a basement passage extending along one side of the coke oven, and from this
conduit branch conduits extend along passages formed under each of the coking
chambers, where they have branches leading up to nozzles at the bottom of each
heating flue.
The essential feature of the invention, which consists in effecting the supply of
the gaseous fuel to the ovens from below, and in rendering the gas supply conduits
accessible at all points in the passages of the substructure, is connected with
several advantages, and at the same time all those disadvantages are avoided
thereby which are connected with coke ovens of present construction in which the
supply of the gaseous fuel is effected from above, or at the heads of the ovens.
By enabling the heating flues of the ovens to be supplied with gas either
separately or at any rate in smaller groups, and also, by enabling the regulation
of the supply of combustible gas to be conveniently effected in the basement
passages, a very uniform distribution of the heat throughout the oven.

in the basement passages, that the gas is subject to a preliminary heating therein,
and that the cleansing of and other attendance on such gas conduits in no way
interferes with the working of the oven.

I, GUSTAV HILGENSTOCK, of Dahlhausen, Germany, Engineer, do hereby
declare the nature of this 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 a construction of coke ovens in which the supply
conduits for the gaseous fuel enter the combustion chambers or flues from
below, and are so arranged in passages formed in the substructure of the oven of
sufficient size for persons to enter them that the said gas conduit shall be accessible
at all points, and that consequently the supply of combustible and the consequent
heat of the fire in the oven can be accurately regulated by suitably arranged
valves.
The invention therefore only relates to the substructure of the coke oven and
to the conduit for the gaseous fuel contained therein, while the construction of the
oven proper and that of the heating flues of the coking chambers &c. may be of
any suitable known arrangement.
The said passages and gas conduits may be arranged in a variety of ways for
the purposes of this invention; thus according to one arrangement, a central
longitudinal passage is arranged in the substructure below the coke oven from
which lateral passages branch off on each side, there being one such passage under
each coking chamber.
The main gas supply conduit runs along the central main passage, and from this
conduit lateral branch conduits extend into each lateral branch passage, where
such branch conduits have other branches extending up to nozzles in the bottoms
of the heating flues on each side of each coking chamber.
According to another arrangement there are a number of longitudinal passages
running under all the coking chambers and each containing a gas supply conduit,
from which lateral branches rise to nozzles contained in the heating flues of the
chambers.
According to another arrangement the main gas supply conduit is contained in
a basement passage extending along one side of the coke oven, and from this
conduit branch conduits extend along passages formed under each of the coking
chambers, where they have branches leading up to nozzles at the bottom of each
heating flue.
On the accompanying drawings are shewn sections of several arrangements of
the substructure of a coke oven with horizontal passages for the purposes of my

page_text: invention; Figs. 11, 12 and 13 show diagrammatic views of the improved arrange-
ments, Fig. 11 shewing the elevation of the foundation arches and gas supply
conduit of a battery of coke ovens, while Figs. 12 and 13 show sectional plans of
such a battery; Fig. 13 shewing an arrangement with a central main passage
extending along the entire length of the coke ovens.
In all the arrangements the passages that allow of the access of persons are
indicated by the reference letter K the main conduit for the gaseous fuel with G,

The essential feature of the invention, which consists in effecting the supply of
the gaseous fuel to the ovens from below, and in rendering the gas supply conduits
accessible at all points in the passages of the substructure, is connected with
several advantages, and at the same time all those disadvantages are avoided
thereby which are connected with coke ovens of present construction in which the
supply of the gaseous fuel is effected from above, or at the heads of the ovens.
By enabling the heating flues of the ovens to be supplied with gas either
separately or at any rate in smaller groups, and also, by enabling the regulation of
the supply of combustible gas to be conveniently effected in the basement passages,
a very uniform distribution of the heat throughout the oven can be effected.
By this means a very uniform coking of the coal is attained, and at the same
time the brickwork, which in other coke ovens is very subject to cracking on
account of unequal heating, is preserved from such damage.
By supplying the combustible gas from below the advantage is also attained
that the upper part of the furnace, to which all the heat ascends, does not become
overheated, the main portion of the heat being given off to the lower part of
the oven.
As the distilled gases collect in the upper part of the furnace, the avoidance
of overheating in this part enables these gases to be preserved in their proper
condition, and prevents them from being more or less decomposed by overheating
whereby valuable constituents thereof are destroyed, as is the case with coke
ovens of present construction.
It is also of importance that the gas supply conduits are effectually protected in
the basement passages, that the gas is subject to a preliminary heating therein,
and that the cleansing of and other attendance on such gas conduits in no way
interferes with the working of the oven.
Having now particularly described and ascertained the nature of this inven-
ion and in what manner the same is to be performed, I declare that what I
claim is
A coke oven wherein the gaseous fuel is made to enter the heating flues of the
ven from below, and in which the combustible gas conduits G, g, d, are arranged
n passages K formed in the substructure of the oven and so constructed as to
allow of the access of persons, substantially as described.
