Year: 1880

page_text: LETTERS PATENT to Maurice Bauer, Civil Engineer, of the Firm of M. Bauer
and Company, Solicitors of Patonts, of 30, Boulevard Magenta, Paris, in
the Republic of France, for an Invention of "IMPROVEMENTS IN KILNS."
A communication from Johannes Quistorp, of Stettin, in the German Empire.
PROVISIONAL SPECIFICATION left by the said Maurice Bauer at the Office
of the Commissioners of Patents on the 24th January 1880.

"IMPROVEMENTS IN KILNS." A communication from Johannes Quistorp, of Stettin,
in the German Empire.
The Invention has for its object the utilization of the waste gases discharged by
brick-cement-lime or other kilns, and consists in closing the kilns at the top,
arranging them in a ring or series, and establishing communication between
adjoining kilns in such a manner that the gases of combustion can be made to pass
from the top of one kiln to the bottom of the adjoining kiln, in order to dry and
heat the material to be burnt in the latter. A valve or slide placed in each flue.
between two kilns, and movable from outside, serves to establish or interrupt at
will the communication between adjoining kilns, which are by preference arranged
concentrically round a common chimney. Each kiln has an opening for charging
it at the top, through which the material to be burnt is introduced, and which is
afterwards closed, and another opening at the bottom, through which the goods are
taken out after burning. Each kiln communicates with the chimney by two flues
at different heights, and provided with suitable valves, slides, &c., which can be
opened or closed at will. The working of the kilns is continuous, the hot gases
passing from the top of the first kiln to the bottom of the second, from the top of
the second to the bottom of the third, and so on, until they escape into the
chimney; each kilo is emptied and filled while the others are in operation. The
material to be burnt and the fuel form, in most cases, alternate layers in the kilo,,
and instead of a chimney any other known means may be used for producing the
required draught.

adjoining kilns in such manner that the gases of combustion can be made to pass
from the top of one kiln to the bottom of the adjoining kiln, in order to dry and
heat the material to be burnt in the latter. A valve or slide placed in each flue
between two kilus, and movable from outside, serves to establish or interrupt at
will the communication between adjoining kilns, which are by preference arranged
concentrically round a common chimney. Each kiln has an opening for charging
it at the top, through which the material to be burnt is introduced, and which is
afterwards closed, and another opening at the bottom, through which the goods are
taken out after burning. Each kiln communicates with the chimney by two flues
at different beights, and provided with suitable valves, slides, and so forth, which
can be opened or closed at will. The working of the kilns is continuous, the hot
gases passing from the top of the first kiln to the bottom of the second, from the
top of the second to the bottom of the third, and so on, until they escape into the
chimney; each kiln is emptied and filled while the others are in operation. The
material to be burnt and the fuel form in most cases alternate layers in the kiln,
and instead of a chimney any other known means may be used for producing the
required draught.
In order that the said Invention may be well understood I have hereunto
annexed a Sheet of Drawings illustrative thereof, and will refer to the same in the
following description.
Each
A number of kilns A'-A8 are arranged in a ring or in series around a
chimney S, establishing communication between each other through the passage a,
and also with the chimney stack S through the passages b and c.
The passages b
and center the chimney room R, communicating with the stack S through the
passage. The passages a, b, c, are provided with movable valves at d, e, f.
kiln is provided with fire bars g. The kilns A¹-A8 are to be charged from a
movable opening J at the top, in such manner that one part of the fuel and one
part of the material to be burned is by turns supplied, after which the kiln A¹ will
be fired at g. The passage a is to be previously closed by means of the valve at d,
while the passages b and c in A' leading to the chimney room R are open. The
passages b and c have for purpose to convey from certain heights the developed
smoke and gases of combustion to the chimney room R, and from there to the
chimney stack S.
When the burning is accomplished to c in A¹ the valve at f of
A is to be closed, and also that at b, A¹, as soon as the process at b is finished.
The passage a leading to A³ is then to be opened through the valve d, the gases
thus passing through a and g to A².
The closing and opening of the valves at d, e, f, can be made in the same manner
as at A', and so forth, the working of the kilns being thus a continuous one.
As soon as the burning of the kiln A' is finished the material burnt may be
taken out through an opening hat the bottom, and the kiln afterwards charged
anew through the opening J, and so forth.

page_text: Having now described the nature and particulars of the said Invention I
claim,―
The combination of the different kilns in order to form the continuous system,
wherein,―
1. The burning process in each kiln takes place from the bottom upward to
the top.
2. The discharging of the gases of combustion from each kiln carried through, at
most, two passages c and b, the one of which is placed in the middle height and the
other one at the top of the kiln, both leading directly to the chimney pipe.
3. The passing of the hot gases of combustion to the adjoining kiln, as specified.
4. The passages c and b having for purpose to convey the smoke and discharged
gases, and the passage a conveying the hot gases of combustion.
5. Each kiln provided with an arch from which the charging of the kiln through
the opening J is to be effected.
6. The arrangement of the kilns, chimnies, and chimney room in such manner
that the shortest, length of passages is employed.
7. The chimney room R arranged over the highest of the passages b, as herein
described in reference to and shown by the Figures of the Drawings.
In witness whereof, I, the said Maurice Bauer, have hereunto set my hand
and seal, this Nineteenth day of July, in the year of our Lord One thousand
eight hundred and eighty.
