paratus.

The special and valuable features
claimed for this process and appara.
tus are as follows:
1. 1t provides the cheapest, clean.
est, quickest and least laborious
method of handling soft coal.
The coal is handled but once. 1t
Is charged into the Cicero generators
500 pounds at time, and is con.
verted. practically, into gas and ash.
es. Chemically speaking, the carbon
and hydrocarbons Of the coal are
combined with the oxygen Of the air
while heating up, and with the oxy.
gen and hydrogen Of the steam while
making gas. The primary products
Of combustion, generated, while heat
Ing up, are completely burned while
hot, aud the resulting heat is stored
In superheaters and condensers. The
heat SO stored in the superheaters Is
utilized In the superheating OF steam,
the vaporizing Of oil, and the fixing
Of gas, so that the heat taken from
the coal while heating up is imme.
diately used and reabsorbed In max.
Ing gas The operation, as In all
water.gas apparatus, Is alternated by
heating up and making gas, each
operation requiring eight to ten
minutes.
.. 1t provides the quickest meth.
cd OF coking bituminous coal, and
the best possible disposition OF the
resulting coke.
The coal Is thoroughly cooked In
about twenty to thirty minutes. It
Is confined between bodies OF incan.
descent fuel on the one hand. and
bodies Of red.hot brickwork on the
other, In free open Communication
with both. The coking.chambers are
each supplied with three separate
air blasts, two beneath the coal and
one above; the former for producing
combustion In the coal, and the lat.
ter to burn the primary products OF
combustion while heating up, thus
causing a volume Of burning gases
to pass over the surfaces Of the COX.

gas generators. Any grade OF bitnm.
inoms coal can be quickly and thor.
ouRhly cooked, by applying portion
OF all OF these means to 1t, Is
required. The coke then falls BY
its own gravity into the con.
Meeting gas.generators, In which
the carbon contained In II Is com.
pletely combined with the oxygen Of
the air while heating up, and the
oxygen and hydrogen Of the steam
while making gas. Nothing remains
but the ash.
3. 1t provides the only possible
method whereby the primary products
of combustion, generated while
heating up, can be completely burned
by the admission Of the exact amount
OF air required.
These products are practically one.
third combustible (carbonic oxide
and hydro-carbons) and two-thirds
non.c mbustile (carbonic acid and
nitrogen). In generators which are
heated from the base upward or
downward, or both, by forced blasts,
when sufficient air Is admitted
to burn, say. one.half Of the
combustible gas, the mixture Is
then one.sixth combustibls and five.
sixths non.combustible The burned
gases will instantly extinguish com.
bustion. In this condition 1t Is i'm
possible to burn the other one-siXth
combustible gas without the admis.
sion OF such a large volume Of air
that it cools the superheater of as
rapldly as the combustion heats it
up, and therefore, in practice, but
about onehalf Of the combu.tible gas
Is burned, and the other half escapes
and finally burns in the open air,
causing a serious loss and waste OF
fuel, besides the labor required to
supply the extra fuel. BY passing
the burned products downward
through the superheaters, instead Of
upward, and exhaustlng the burned
gases as rapidly as they are gener-
ated, as operated in this apparatus,
complete and perfect combustion is
secured without the admission OF
superiiuous air, thereby saving the
fuel and labor previously lost and
wasted, and economizing in the man
ufacture OF gas.
I. 1t provides the best method OF
storing heat
The heat generated while heating
up the apparatus. preparatory TO
making gas, is stored in superheat-
ers or regenerators having outlets at
their bases. These are chambers
