An Improved Method of Utilising the Waste and Dross of Coal
in the Manufacture of Briquettes for Use as Fuel.
I LOUIS ABRAHAM BRODE residing at No. five St. Andrews Road Pollokshields
Glasgow do hereby declare the nature of this invention to be as follows:-
The Coal waste or dross having been ground to a powder is placed in a mixing
machine. There is then added to the powder a sufficient quantity of a solution pro-
duced by the combination of boiling water-farina or Ground Rice Waste or the waste
of similar substances and Silicate of Soda-in certain proportions. The whole
being then thoroughly mixed produces a thick clayey substance which is moulded into
bricks and dried.

An Improved Method of Utilizing the Waste and Dross of Coal
in the Manufacture of Briquettes for Use as Fuel.
I, LOUIS ABRAHAM BRODE residing at No. five St. Andrews Road, Pollokshields,
Glasgow, Enameller 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 :-
This Invention relates to an improved method of utilizing the waste and dross of
coal in the manufacture of briquettes for use as fuel.
In carrying this Invention into practice the coal waste or dross having been ground
or otherwise reduced to a powder is placed in a mixing machine. There is then added
to the powder a sufficient quantity of a solution produced by the admixture of Farina
or ground rice waste or the waste of similar substances and Silicate of Soda in certain
proportions. The proportions which the Inventor has found to answer in practice are
one hundredweight of coal dross or waste, one per cent. by weight of Farina or ground
rice waste and two ounces of Silicate of Soda. These substances are mixed with
boiling water sufficient in quantity when thoroughly commingled therewith to produce
a thick clayey substance which is moulded into Bricks or briquettes pressed and dried.
In place of using boiling water the substances may be mixed together in the dry
state in which case the mixture is moistened in a chamber whereinto steam is admitted
thereby producing the necessary moist or clayey like condition of the mixture.
In place of pressing the bricks or briquettes this may in some cases be dispensed
with and the moulded bricks or briquettes in this case are simply dried.
Having now particularly described and ascertained the nature of the said Invention
and in what manner the same is to be performed, I declare that what I claim is :-
The method or manufacture of briquettes for use as fuel from ground or otherwise
pulverised coal waste or dross placed in a mixing machine or steam chamber together
with a sufficient quantity of Farina or ground rice waste or analogous waste and
Silicate of Soda together with boiling water or steam for the purpose of producing
Briquettes for use as fuel substantially as hereinbefore described.
