terials which Americans have not yet
succeeded in converting into satisfac-
tory briquettes. There are experienced
engineers and dozen manufacturers
of briquette-making machinery who
would gladly cooperate in these tests
and would furnish machinery adapted
to working the material thus techni-
cally defined. Upon basis of such
tests, plans and estimates could be OBJ
tained for the erection Of plants in the
United States with specified daily ca
pacity.
The Stauber process for drying most
substances was first brought into prom
inent notice in connection with peat
coal manufacture in 1901, when the I'M
perial testing station at Charlottenburs
announced as the result of experiments
made with peat briquettes made by the
Stauber system that they contained
4514 per cent Of fixed carbon, Ash per
cent hydrogen, 1884 per cent oxygen
and 900 per cent ash and had a Their
NAL value of 3,SO6 calories. The Stau-
Der system as thus applied includes a
process for rapidly drying the moist
peat by means of heated and compress
ed air within closed chamber or chan
mel, communicating with conduit pipes
in such manner that heated air can
be forced through the drying channel
and cold air through the outlet pipe, the
effect being that the cold air quickly
absorbs the hot, saturated air out OF
the drying chamber and condenses it in
the conduit pipes, thus greatly stimu-
lating the process Of evaporation by
which the peat is dried. Peat in its
raw state contains from 20 to IS per
cent Of water and in the humid climate
of northern Europe is usually very
difficult material to dry. 1t is claimed
for the Stauber method that it reduces
the moisture to 10 or 20 per cent quick
ly, effectively and, what is important,
without changing the chemical compo-
sltlon of the peat or in any way add
ing to it. The drying machine is in
the boiler form (cylindricaD and Of d
size to conveniently produce five tons
Of dried peat per day.
"a second process is that invented by
F. Schulke Of Bach strasse, Hamburg,
the salient feature of which is that the
turf or peat used is cleaned Of roots,
stones, etc., then liquified by water and
pumped through pipe several miles to
the works, where, as claimed by the
inventor, it is leached and converted
by heat and pressure into briquettes Mt
net cost OF 81 per ton, or into arti-
fetal coal having thermal value of
$3.50 calories at cost of $3.50 per
ton. 1t is understood that large plant
is in process of erection on the northern
coast of Germany for the utilization of
this. method. but as to the actual con-
dition of the enterprise or the prac-
teal value of the process on an indus
trial scale. no exact information is at
hand.
"The Schoening- Fritz process for
making artificial coal and briquettes by
carbonizing dried peat Is an elabora-
ton by a German engineer of the sys-z
TEN invented by Schoening and used
with more or less success at Stamsund,
in Norway. e,,>4. s..s
"Of the processes actually employed,
the value of which has been fully es-.
tablished by experience. one Of the
most interesting is that invented by
G. Schlickeysen of Rixdorf- Berlin and
practically operated there. at Munich
and other places. The peculiar feature
Of this system IS that by it black. dense.
