Improvements in the Manufacture of Fuel.
I, AUGUSTE BESSON of 35 Boulevard des Capucines, Paris, France, Merchant
do hereby declare the nature of this invention to be as follows:-
My improvements have for object the production of a new combustible agglomera-
tion utilizing the small broken pieces and dust of all kinds of coal and of coke, and
suitable for all kinds of domestic or industrial fire places and especially for stoves or
portable heating appliances.
The improvements consist in the mixture, in suitable proportions and in presence
of water, of small particles of various kinds of coal with each other and with an
agglomerating silicate or silicious substance so as to obtain a paste of plastic con-
sistency, that can be moulded to various sizes and shapes.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Fuel.
1, AUGUSTE BESSON, of 33 Boulevard des Capucines, Paris, France, Merchant, 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 for object the production of a combustible agglomerate or fuel
from small broken pieces and dust of all kinds of coal and coke, and suitable for use
in all kinds of domestic or industrial fireplaces and especially for stoves or portable
heating appliances.
The improvements consist in the mixture, in suitable proportions and in presence of
water, of small particles of various kinds of combustible substances with an
agglomerating silicate or silicious substance so as to obtain a paste of plastic con-
sistency that can be moulded into blocks of various sizes and shapes.
Combustible agglomerate or fuel prepared according to this invention is capable of
being easily handled has a great calorific power, is easily ignited and burns well with
a minimum production of smoke.
In carrying out this invention I proceed as follows:-
Into a vessel of suitable capacity I place wood-charcoal, in the form of dust or
powder, and to it 1 add a certain quantity of silicate. I dilute the mixture, whilst
stirring it, with a certain quantity of water; then, I gradually introduce some
anthracite or other kind of mineral coal or coke in a powdered state the mass being
meanwhile continually stirred and mixed. When the paste has attained the desired
plastic consistency, I mould it between dies of suitable size and shape, in a manner
similar to that in which brick clay is moulded.
The proportions of the several substance with which I have obtained a good result
are as follows:-

page_text: The wood-charcoal dust in the proportion mentioned serves to ensure the ignition
and combustion of the agglomerate or fuel, and the silicate serves to effect the
agglomeration of the various particles. of combustible matter with a minimum
quantity of agglutinating medium. The agglomeration may be effected by silicate
of soda or potash, or by a hydro-fluo-silicate.
The product after having been moulded may be dried in the open air or otherwise,
as in the case of bricks, tiles and the like.
The blocks of agglomerate or fuel may be made solid or perforated, and may,
if desired, be of the shape of the hearth in which they are to be burnt, but I have
found by experience that combustion cannot take place in a satisfactory manner
unless the agglomerate or fuel be broken up into small pieces just before it is used
in order that it may present a sufficiently large surface for combustion.
Combustible agglomerate or block fuel according to this invention permits of the
utilization of the natural dust or waste of various kinds of coal or coke.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
The manufacture of a combustible agglomerate or fuel, from the dust or powder of
various kinds of combustible substances or fuels, bound together by a silicate in the
manner and according to the proportions hereinbefore specified.
