page_text: I, FÖRGEN GEORG MAARDT, of 10, Vestre Boulevard, Copenhagen, in the King-
dom of Denmark, Engineer, do hereby declare the nature of this invention to be
as follows:-
:-
The present invention relates to a lime or brick kiln of annular or oblong
shape which works continuously and is heated by the combustion of the coal-
gases produced in the coke-kiln-generators while the burning gases before they
are led away to the chimney serve to develop the gases in the following coke-
kiln-generators, the volatile components of the coal only being used for burning
lime or brick, whereas the remainder of the coal is removed as coke or cinder.
Below the kiln-arches in which the lime or bricks are burned, a series of trans-
verse arches is arranged which act as coke-kiln-generators for the production.
of the gases, by means of which the burning takes place. The said coke-kiln-
generators are successively filled with coal being first heated; and the gases
produced from the coal by means of the heat of the kiln will then pass through
the openings above the kilns into the arches where they are lighted by the
entrance of air and thus effect the burning. The burning gases at first pass to
the next coke-kiln-generator which is thus heated before being filled with coal;
and from there they pass through the flues to the head-channel and through it
to the chimney. The passage of the burning gases through the right coke-kiln-
generator is regulated by the dampers which interrupt communication between
the flues and the head-channel. Gradually as the burning in 'the kiln advances
the first used coke kiln generators are emptied and the following generator filled
with coal being first heated in the above described manner. The burning is
continuous. The coke-kiln-generators can also be arranged outside the lime-
kiln, and the gas is then led through channels to the various chambers.

page_text: in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The present invention relates to a lime- or brick-kiln of annular or oblong
shape which works continuously and is heated by the combustion of the coal-
gases produced in the coke-kiln-generators, while the burning gases before they
are led away to the chimney serve to develop the gases in the following coke-
kiln-generators, the volatile components of the coal only being used for burning
lime or brick, whereas the remainder of the coal is removed as coke or cinders.
In the accompanying drawings..
:
Figure 1 shows a transverse section through a kiln of oblong shape.
Figure 2 shows a longitudinal side elevation partly in longitudinal section;
and
Figure 3 is a horizontal section of the kiln on the line a-b Figure 1.
Below the kiln-archies A in which the lime or bricks are burned, a series of
transverse arches B is arranged which act as coke-kiln-generators for the produc-
tion of the gases, by means of which the burning takes place. The said coke-
kiln-generators are successively filled with coal being first heated; and the gases
produced from the coal by means of the heat of the kiln will then pass through
the openings C above the coke-kiln-generators B into the kiln arches A where
they are lighted by the entrance of air and thus effect the burning. The burning
gases at first pass to the next coke-kiln-generator B which is thus heated before
being filled with coal; and from there they pass through the flues E and F to the
head-channel G and through it to the chimney H: The passage of the burning
gases through the right coke-kiln-generator is regulated by the dampers I which
interrupt communication between the flues F and the head-channel G.
Gradually as the burning in the kiln advances the first used coke-kiln-generators
are emptied. and the following generator filled with coal being firstly heated in
the above described manner. The burning is thus continuous. The coke-kiln-
generators. can also be arranged outside the lime-kiln, and the gas is then led
through channels to the various chambers.
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:
1. 4
1.A continuously working lime- or brick-kiln-connected with coke-kiln-
generators which are arranged either inside or outside the lime-kiln; substantially
as: described and illustrated in the accompanying drawing.
2. In kilns of the kind referred to in Claim I the arrangement, in which the
coke-kiln-generators are located inside the lime-kiln in such a manner, that
they can be filled with coals being first successively heated by the burning gases
produced by the combustion in the arches of the annular or oblong kiln of the
gases generated in the leading coke-kiln-generators, before the burning gases
pass away to the chimney.

3. In kilns of the kind referred to in Claim 1 the arrangement of flues at the
sides of the coke-kiln-generators. these flues leading the burning gases to a
head-channel and through it to the chimney; substantially as described and
illustrated in the accompanying drawing.
