COMPLETE SPECIFICATION.
Improved Brick Kiln, with Arrangement for Drying the Unburnt
Bricks.
I, OTTO HERTRAMPF, of 48, Hermannstrasse, Breslau, in the Empire of Germany,
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:-
-
The object of this invention is to utilise the gases given off from the fire, the
heat from the smoke and the hot vapours generated by the latter from the
material, which hitherto have passed away unused through the smoke collector and
chimney into the open air, after the material has been left to burn, for drying the
unburnt bricks piled up over or around the kiln in a drying compartment.
In the accompanying sheet of illustrative drawings Fig. 1 is a sectional elevation
of a kiln constructed according to this invention, and Figs. 2 and 3 are sectional
plans taken through the lines -- and y-y respectively Fig. 1.
Adjoining the principal flues a running from the burning chamber to the smoke
collector, subsiding flues a¹ are arranged, which communicate, by means of con-
necting channels b, with a heat supply channel c. The channel c is situated
beneath the hearth bottom and, if the kiln be an annular one, runs completely
around it. This channel communicates by means of one or more connecting
channels with vertical shafts e, and through the shafts e with heat supply pipes f,
which are arranged under the bottom of the drying compartment and communi-
cate through a connecting pipe g, and a valve h, with the smoke collector and
thereby with the chimney.
The action is as follows:-If the heat in the fire chamber is to be utilised for
drying the unburnt bricks the main flue of this chamber is stopped in the direction
of the smoke collector and the cap of the subsidiary flue a "pulled." The fire
gases are then drawn through the subsidiary flue of this chamber and its
connecting channel b into the heat supply channel e, thence through the connect
ing channel d and the vertical shaft e into the heat supply pipes f, heating them,
and, following the draught of the chimney, pass away through the connecting
channel g, the outlet valve h, the smoke collector and the chimney, into the open
air. The heat from the pipes f is communicated to the upper drying spaces, in
which the unburnt bricks are piled up. If the heat from the smoke and the smoke
vapours from the smoking chamber are to be utilised, the principal flue of this
chamber is stopped and the subsidiary flue thereof opened. The course of the
heat from the smoke and of the smoke vapours is exactly the same as previously
described.
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:
A brick kiln with arrangement for drying the unburnt bricks piled up above
the same in a drying compartment, the distinguishing feature being that beneath.

page_text: the hearth bottom a heat supply channel e is arranged, which communicates on
the one hand by connecting channels b, and subsidiary flues a¹, with the principal
flues a running from the chambers to the smoke collector, and on the other, by
connecting channels d and vertical shafts e with heat supply pipes f arranged
beneath the upper drying spaces, and which, in turn, communicate through
connecting channels and a through draught valve h, with the smoke collector
and the chimney.
