Lehigh, N. d., Nov. 15.-Afte,
months OF preparation, the Lehigh
briquetting plant is nearly ready
for operation. The first briquets
will be sent from the plant in Decem-
Der.
First test "runs" of the carbonizer
will be made by officials at the plant
in the near future, and some carbon
char will be turned out this month,
according to officials at the plant.
There has been some delay in the
completion of the briquetting build
ing owing to delayed delivery Of
special structural steel, but it is ex-
pected that this building will be COM
pleted soon so that the first run of
briquets will be made sometime in
December.
AS soon as the plant is in capacity
production, several additional car
bomber ovens will be added to those
in the plant now, which will increase
the plant capacity several times and
reduce production costs, according
to E. B. Whitman, fiscal manager.
use German Process
This plant is the first American
installation of the Lurgi process of
Ignite carbonization-a German
development which is operating COM
mercially with success in Germany,
Austria, Slovakia, Greece and other
European points where Ignite is
found" Whitman said.
THE power plant has two water
tube boilers with automatic chain
crate stokers burning Ignite slack
local waste). This plant is COM
pleted with generator, evaporators
and spray pond. Water is obtained
three-fourths Of a mile from the
plant at the Heart river, where an
automatic pumping station is To-
Gated. A six inch cast iron main is
laid five feet underground. This
water is distilled for boiler purposes.
The plant is also equipped with a
complete water drainage system with
12-inch main and separate sew
erage disposal system-all of which
IS built to handle future additions to
the plant. A complete water circu-
iating and storage system, electric
lighting and power generator for
power distribution has been installed.
"A complete chemical laboratory
has been provided for testing fuel,
binder pitch, by-product oils and
gases.
Treatment Described
The treatment of the Ignite con-
sists first of crushing the fine coal,
dust being conveyed to the power
plant for steam fuel, and the clean
larger pieces being elevated by con-
veyor to the upper oven in the steel
tower where the water and non.
combustible gases are driven off.
''The coal then is conveyed into
the lower oven where under in
creased temperature the tar is driven
out. The residue, which has then
become a semi-coke or carbon char,
passes through a cooling zone to
form the base of the new fuel. The
tar is broken up in the disintegration
plant, where the pitch is isolated
from the creosote oils and inflam-
mable gases.
The pitch is pumped to the bri-
quoting plant, where in super
heated steam it passes as a vapor for
mixture with the char to form a
binder. This mass is then run
through the briquetting rolls and
the briquet is complete.
The gases are then separated
from the by-product oils and piped
to the ovens where they are con-
sumed in the coking process.
