IMPROVEMENTS IN GENERATING STEAM IN STEAM BOILERS
Year: 1853

page_text: LETTERS PATENT to Jacob Behrens, of Bradford, in the County
of York, Merchant, for the Invention of "IMPROVEMENTS IN
GENERATING STEAM IN STEAM BOILERS."-A communication.
PROVISIONAL SPECIFICATION left by the said Jacob Behrens at
the Office of the Commissioners of Patents, with his Petition,
on the 14th September 1853.
I, JACOB BEHRENS, of Bradford, in the County of York, Merchant,
do hereby declare that the nature of the Invention for: "IMPROVEMENTS
IN GENERATING STEAM IN STEAM BOILERS" to be as follows:-
This Invention has for its object peculiar means of applying the
heat evolved when making coke in a coke oven to the purpose of
heating a steam boiler. It should be stated that it has before been
proposed to employ the waste heat passing off from a coke oven to
heat a steam boiler, but up to the present time no successful result has
been obtained; and the present Invention consists of setting one end of
a steam boiler (thro' which a tubular flue runs) in the crown of a coke

page_text: oven, there being openings or passages from the outer part of the
under side of the boiler which enter the tubular flue in the interior of
the boiler, and the tubular flue thro' the boiler is closed at the front
end, and open only at the other end; by which means the heat evolved
from coal in the process of coke making passes up the passages into the
tubular flue, and thro' it into the stack or chimney, and thus is the
steam boiler heated.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Jacob Behrens in the Great Seal Patent Office
on the 7th March 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JACOB BEHRENS, of Bradford, in the County of York, Merchant, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of September, in the
year of cur Lord One thousand eight hundred and fifty-three, in the
seventeenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Jacob Behrens, Her special licence
that I, the said Jacob Behrens, my executors, administrators, and
assigns, or such others as I, the said Jacob Behrens, my executors, ad-
ministrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN GENE-
RATING STEAM IN STEAM BOILERS," communicated to me from abroad,
upon the condition (amongst others) that I, the said Jacob Behrens,
by an instrument in writing under my hand and seal, should par-
ticularly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Jacob Behrens, do hereby

page_text: 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 thereof (that is to say):
This Invention has for its object peculiar means of applying the heat
evolved when making coke in a coke oven to the purpose of heating a
steam boiler. It should be stated that it has before been proposed to
employ the waste heat passing off from a coke oven to heat a steam
boiler, but up to the present time no successful result has been
obtained, and the present Invention consists of setting one end of
a steam boiler (through which a tubular flue runs) in the crown of a
coke oven, there being openings or passages from the outer part of the
under side of the boiler which enter the tubular flue on the interior of
the boiler, and the tubular flue through the boiler is closed at the front
end, and open only at the other end; by which means the heat evolved.
from coal in the process of coke making passes up the passages into the
tubular fluc, and through it into the stack or chimney, and thus is the
steam boiler heated.
Having thus stated the nature of the said Invention, I will proceed
to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1, is a longitudinal, and Figure 2, a transverse section taken
through 1, 1, in Figure 1. A, coke oven; B, fire box or chamber
from which the products and heat from the coking oven pass through
the series of tubes in the boiler; and I would state that in place of
having numerous tubes through the boiler one or more may be used.
C, boiler; D, smoke box; E, door to same; F, damper to smoke box;
G, flues to regulate the heat, and also that the operation of coking may
procced regularly during the night and at all times. F', dampers to
flues; H, opening through which any coal or cinders may be cleared
out from the fire chamber; H*, a block of clay or other suitable material
for closing the said opening H; I, fire brick wall laid in dry and
smeared with loam, made air-tight for closing coke oven when charged;
J, draft hole in the same; K, fire clay stoppers for closing some of the
tubes through the boiler, if necessary; L, flue leading into chimney.

page_text: On starting a new oven, after being duly dried and carefully brought
up, the coke oven is charged with coal in the usual way, sufficient
time being allowed for the steam to get up for the first four charges,
which will not be requisite after, when all things have acquired their
heat; if the steam is found to generate too quickly, the damper F, at the
top of the smoke box must be regulated, and, if necessary, closed, and
the flues G, opened. The damper F, must be closed, and the flues G,
opened during the night, or when the steam is not required, and, if
necessary, some cold water admitted. H, opening through which any
coals or cinders may be removed from the fire box or chamber; H*, a
block of clay or other suitable material for closing the said opening H;
I, fire brick wall laid in dry and smeared with loam to make it air-
tight for closing coke oven when charged; J, draft hole in the same;
K, fire clay stopper for closing the tubes through the boiler or part of
them, if necessary. The process of coking being well understood will
not require description, but the damper is only shut for about six hours.
Having thus described the nature of the said Invention, and the
manner of performing the same, I would have it understood that I do
not claim the coke oven or boiler separately. And I would state that
I am aware that it is not now to combine a coke oven with a steam
boiler; I do not therefore claim the same generally. But what I claim
is, the combining a coke oven with a boiler C, and smoke box B, sub-
stantially as shewn and described.
In witness whereof, I, the said Jacob Behrens, have hereunto
set my hand and seal, this Twenty-first day of February, in
the year of our Lord One thousand eight hundred and fifty-four.
Witness,
JOHN DARLINGTON,
of Bradford, Solicitor.
JACOB BEHRENS. (L.S.)
