A CONTINUOUS ARRANGEMENT OF REGENERATING APPARATUS FOR COKE OVENS
Year: 1885

page_text: I RICHARD DE SOLDENHOFF of Cardiff in the County of Glamorgan, Mining
and Civil Engineer, do hereby declare the nature of the said invention for
A CONTINUOUS ARRANGEMENT OF REGENERATING APPARATUS FOR COKE OVENS to
be as follows:-
Coke
ovens using gas for heating are provided with flues in their side walls and
under the floor.
Hitherto the gas after having passed the above named flues enters into the main
flue or chimney, or as in recent improvements the gas is taken outside the block of
ovens into a Siemens's Regenerator or some other system of regenerator situated
at a distance from the ovens.-In the first case the sensible heat left in the gas is
utilised for other heating purposes but is lost to the manufacture of coke; in the
second case of Siemens's or other regenerators, the regeneration is complicated and
costly.
To obviate the said disadvantages and to attain the object of regeneration
I propose to build under the floor of each oven three flues one above the other.
The first flue situated immediately under the floor of the oven receives the gas
which after travelling along the same enters into the third or lowest flue along
which it travels in a similar manner to that in the first or upper flue and from
here it enters into the main flue or chimney. The second or intermediate flue
situated between the first and third flues is an air flue. All the gas flues and air
flues are parallel.
All the air flues of a batch of ovens communicate together, and so that if cold
air is admitted under the first oven of the block it shall become hot when received
by the last oven of the same batch. The air flues being situated between two gas
flues arranged above and beneath it, it is evident that the air will be continuously
regenerated without any great additional cost and without any complication and
without the gas being carried from the ovens outside to regenerators.
The regenerated heat carried by the air is returned to the ovens by distributing
it into the gas flues of the ovens, where the combustion takes place.
The arrangement above described as applied to horizontal ovens, is also
applicable to vertical ovens with this difference that the intermediate air flue
instead of being situated horizontally between two horizontal gas flues, will be
situated vertically between two vertical gas flues.

A Continuous Arrangement of Regenerating Apparatus for
Coke Ovens.
I, RICHARD DE SOLDENHOFF of Cardiff in the county of Glamorgan, Mining
and Civil 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:—
Reference being had to the accompanying drawings in which Figure 1 is a
longitudinal vertical section taken on the line C. D. of Figure 2 of apparatus
constructed according to my invention; Figure 2 is a front elevation thereof partly
in section, such section being taken on the line A. B of Figure 1; Figure 3 is a
horizontal section thereof taken on the lines E. F; G. H; I. J; K. L of Figure 2
and Figure 4 is a horizontal section thereof taken on the lines M. N; OP; of
Figure 2.
Coke ovens using gas for heating are provided with flues in their side walls and
under the floor.
Hitherto the gas after having passed the above named flues, enters into the main
flue or chimney or as in recent improvements, the gas is taken outside the block of
ovens into a Siemens's regenerator or some other system of regenerator situated at
a distance from the ovens,
In the first case the sensible heat left in the gas is utilised for other heating
purposes but is lost to the manufacture of coke; in the second case of Siemens's
or other regenerators the regeneration is complicated and costly.
To obviate the said disadvantages and to attain the object of regeneration,
I propose to build under the floor of each oven three flues A. B. C one above the
other.
The first flue A situated immediately under the floor of the oven receives the gas
which after travelling along the same enters into the third or lowest flue C along
which it travels in a similar manner to that in the first or upper flue, and from
here it enters into the main flue D, or chimney.
The second or intermediate flue B, situated between the first and third flues is
an air flue. All the gas flues and air flues are parallel. All the air flues B, of a
batch of ovens communicate together and so that if cold air is admitted under
the first oven of the block through openings g it shall become hot when it arrives
at the openings F, F by the last oven of the same batch.
The air flues being situated between two gas flues A and C arranged above and
beneath it, it is evident that the air will be continuously regenerated without any
great additional cost and without any complication and without the gas being carried
from the ovens outside to regenerators.
The regenerated heat carried by the air is returned to the ovens by flues or
shafts F, F, and flues G, G, which distribute it into the gas flues E and A of the
ovens by flues h and i where the combustion takes place.
The arrangement above described as applied to horizontal ovens, is also
applicable to vertical ovens with this difference, that the intermediate air flue

page_text: instead of being situated horizontally between two horizontal gas flues will be
situated vertically between two vertical gas flues.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
The regenerating apparatus for coke ovens whereby the air is heated by
traversing a flue situated between two gas flues after which it is distributed into
the side walls of the ovens to promote the combustion of the gases, substantially as
herein shown and described.
