Process OF Making Brlcquettes

Minneapolis Journal: Condi-
tions favor the early development
Of a great Ignite briquette man
ufactpring business in the north
west in the near future. The use
of such fuel has become common
in. Germany, where the industry
has reach vast proportion. Ad-
vance sheets of the consular
reports mention the presence Of
William de la Bere of the Mime
apolis Water Power there to study
the briquette making business.
MI. de la Bere was seat by Cen
eral W::.D. Washburn, who is so
largely. interested in the Ignite
fields of North Dakota, to study
processes with aview to establish
ing a factory in the northwest. In
North, Dakota and Montana there
is layer of Ignite $4,000 square
miles in extent and from 20 to
SO0sfeet thick, and Germany has
pronounced the quality the best
for briquetting. Here is what
the consular reports say of the
test made with it.
LEAVES LITTLE ASH.
sThe. Dakota Ignite is old and
hard, contains 80 per cent of water
but crushes and pulverizes easily
and forms, without binder, bri.
QUOTES of firm structure, which
burn readily, are PRACTICAL smoke-
less, and leave only 4 per cent of
ash, while the best German brown
coal briquettes yield from s to IL
per centof inorganic residue. The
percentage Of water contained is
rather low, but by adapting the
distinguishing process to that
proportion of moisture. this OBJ
stacle, such as it is, can be easily
met, and the reduced task of evap-
Grafton will be an economy in the
general process
A typical German plant not far
from Berlin turns out daily from
500 to 900 tons of b%riquettes
which sells on the cars at the fac
tory for from $l.66 to $2.l4 per
ton. Brown coal briquette compa-
MES in Germany pay dividends
from Is to 20 per cent.
With such profits IN the indus
try, and the vast supplies of lig-
mite in the. northwest, including
the beds in. North Dakota, Mon
tana and some in Iowa, the north
west will doubtless soon see the
development of the business. The
fact that briauettes make an al
most smokeless fuel will also add
to their popularity.
An INTERESTING PROCESS.
The process Of manufacturing is
interesting. Ignite containing
less than 80 per cent of water is
difficult to handle. The part play
ell by the water..contained in lig-
mite forms the key tothe whole
economic briquettipg process. The
crude brown coal is brought from
the mine, crushed and pulverlzesd5,
and then run through q large re-
yolving cylinder, heated by ex-
haust steam from the driving en- n
