AN IMPROVEMENT IN COKE OVENS
Year: 1884

page_text: I, HENRY SIMON of Weissbad near Apenzell, Switzerland, Civil Engineer, do
hereby declare the nature of my said invention for "AN IMPROVEMENT IN COKE
OVENS" to be as follows:-
In the Specification No 554 of 1883 of an invention communicated to me from
abroad, I described a method of utilising waste heat of coke ovens for heating the
air or combustible gas employed in working them, and I described several arrange-
ments of ovens illustrating the practical application of this method. In these
ovens, the products of combustion on their way to the chimney, after having
performed their work of heating, are made to pass along flues while the air or
combustible gas or both are made to pass in the opposite direction along adjacent
flues, receiving heat by conduction through the flue walls before they enter the fire
place or combustion chamber.
a
It is found practically that the heat thus obtained from the combustion is in
Gome cases greater than is necessary or desirable. My present invention relates to
a modification in the construction of the flues constituting what is now known as
recuperator," whereby I am enabled to vary, regulate and temper the heat.
For this purpose, I construct at various points in the length of the longitudinal
recuperator,"-flues, cross flues or channels having openings provided with valves
or dampers, so that I can admit the cold air or combustible gas into different parts
of the recuperator-flues, whereby it is made to receive more or less heat according
as it travels along a greater or less length of flue on its way to the combustion
chamber.

COMPLETE SPECIFICATION.
I, HENRY SIMON of Weissbad, near Apenzell, Switzerland, Civil Engineer, do
hereby declare the nature of my invention for "AN IMPROVEMENT IN COKE
OVENS" and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
In the Specification No 554 of 1883 of an invention communicated to me from
abroad, I described a method of utilising waste heat of coke ovens for heating the
air or combustible gas employed in working them, and I described several arrange-
ments of ovens illustrating the practical application of this method. In these
ovens the products of combustion, on their way to the chimney after having
performed their work of heating are made to pass along flues while the air or
combustible gas or both, are made to pass in the opposite direction along adjacent
flues, receiving heat by conduction through the flue walls before they enter the fire
place or combustion chamber. It is found practically that the heat thus obtained
from the combustion is in some cases greater than is necessary or desirable. My
present invention relates to a modification in the construction of the flues consti-
tuting what is now known as a "recuperator," whereby I am enabled to vary,
regulate and temper the heat.
For this purpose, I construct at various points in the length of the longitudinal
recuperator-flues, cross flues or channels having openings provided with valves or
dampers so that I can admit the cold air or combustible gas into different parts of
the recuperator-flues whereby it is made to receive more or less heat according
as it travels along a greater or less length of flue on its way to the combustion
chamber.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed, I declare that what I claim is
Constructing the "recuperator" flues of coke ovens with cross flues or channels
at various points of their length, having openings provided with valves or dampers
by means of which cold air or combustible gas can be admitted into the recuperator
flues at such points substantially as and for the purpose described.
