Improvements relating to the Manufacture of Artificial Fuel.
1, FERDINAND JOHANN KOOPMANN, of 35 Leopoldstrasse, Munich, in the
Empire of Germany, Director, do hereby declare the nature of this invention to be
as follows:-
:-
My invention relates to the manufacture of artificial fuel.
In order to manufacture artificial fuel which is as free as possible from sulphur
and burns without hardly any smoke, I mix with small coal according to its
condition from 6 to 12 per cent. of pulverized spar or marble and from 4 to 8 per
cent. of peels and waste of stones of the palm and other similar oleaginous fruit,
which latter serves by itself or together with specially added substances as a binding
agent, the mixture being pressed into moulds by mechanical means.
In consequence of the proportion, in the fuel, of waste of oleaginous fruit which
still contains oily ingredients, this fuel is easily ignitible and burns with a vivid
flame. The oily ingredients also protect the other parts of the fuel against
moisture, inasmuch as they enwrap the same and keep off exterior moisture.
By reason of the addition of pulverized spar or marble, small channels are formed
in the coal, such channels taking up oxygen. At about 700 degrees Centigrade the
carbonic acid becomes free from the selected marble or spar and, in combination
with the carbonic acid from the coal and the oxygen contained in the fuel, increases
the heating power to such an extent that smoke and soot will also be burnt, and
that no spark is liable to fly from the chimney, and if really a spark should
occasionally fly out it falls dead on the ground, having lost its igniting power.
The formation of slag is likewise obviated, because the small grains of spar or
marble separate the particles of coal and do not allow them to bake together.
Moreover, very little ash remains behind, as owing to the great heat all the
combustible parts of the fuel are actually burnt.
By the addition of spar or marble the sulphur in the coal is destroyed.

COMPLETE SPECIFICATION.
Improvements relating to the Manufacture of Artificial Fuel.
I, FERDINAND JOHANN KOOPMANN of 35 Leopoldstrasse, Munich, in the
Kingdom of Bavaria, and Empire of Germany, Director, 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 :—
My invention has reference to improvements relating to the manufacture of
artificial fuel and the object of the improvements is to produce an artificial fuel
which is as free as possible from sulphur and burns with hardly any smoke; to this
end my improved artificial fuel consists of small coal or coal dust, disintegrated
spar or marble, and of peels and waste of the nut of the palm or other oleaginous
fruit.

according to its condition from 6 to 12 per cent. of pulverized spar or marble and

similar oleaginous fruit, which latter serves by itself or together with specially
added substances as a binding agent, the mixture being pressed into moulds by
mechanical means.
In consequence of the proportion, in the fuel of waste of oleaginous fruit which
still contains oily ingredients, this fuel is easily ignitible and burns with a vivid

moisture, inasmuch as they enwrap the same and keep off exterior moisture.
By reason of the addition of pulverized spar or marble small channels are formed

of slag is likewise obviated, because the small grains of spar or marble separate

little ash remains behind, as owing to the great heat all the combustible parts of the
fuel are actually burnt.
By addition of spar or marble the sulphur in the coal is destroyed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
The hereindescribed improvements relating to the manufacture of artificial fuel
consisting in mixing small coal or coal dust with grained or pulverized spar or
marble and peels or waste of the nuts of the palm or other similar oleaginous fruit
in the proportions specified, with or without an addition of special binding substances,
substantially as set forth.
