Rev Process the Best.
In other water gas apparatus the
air and gases are forced through the
apparatus both when admitting air
and heating up, and when admitting
steam and making gas the pressure
gauges showing a pressure of fifteen
to thirty inches of water pressure
This results in very imperfect com
bustion of the primary products (or
gases generated while heating up) as
shown by the combustion of large
,-o1np,o Of ,1pbnrpa6 prip,arv prod
ucts, which burns at the top of such
apparatus while heating up, the heat
thereby generated going to waste in
the open air. This primitive method
results also in radical defective
chemical changes and combinations
while making gas. On the contrary,
in the Rev apparatus the pressure is
entirely taken off by the use of an eX-
haust, both while admitting air and
heating up and while admitting
steam and making gas, the pressure
gauges standing at zero or showing a
slight vacuum. This improved method
provides for the complete com bustion
of the primary products within the
apparatus while heating up and per-
feet chemical changes while making
gas, thereby requiring less fuel and
not only greatly cheapening the cost
of gas but also greatly improving it
in quality This gas is much better
fixed" than gas made under pressure
burns with a smoother and more
brilliant fame and can be transported
farther through gas mains with less
and practically no condensation of
the oil vapors.
In other water:gas apparatus when
the fires are cleaned of ash and
clinker and the generators are sup
piled with fresh coal, the apparatus
is completely stopped, and the top of
the apparatus is thrown open in or
der to create draft and draw the
heat and gas from the StOkers and
operators This causes a serious loss
of time and great waste of heat
and gas.
On the contrary, in the Rev ap-
paratus the fires are cleaned and ash
es and clinkers withdrawn and fresh
fuel is added while heating up the
apparatus and without loss of time,
gas or heat. These superior effects
are produced by the use of continu-
Gus exhaust this feature being en-
tirely novel and new, and a most de-
cided and radical improvement over
every other process and apparatus in
the market.
City Would Make Money.
The price which the citizens are
now paying to the gas trust is S1.2O
net. The output Of the trust is about
3, 400, 600, 900. The price of the City
and County Gas Company shows a
saving of 40 cents per thousand, or
over 81, 250,0 600 per year. As the bulk
Of the Chicago gas trust is now owned
by Eastern capitalists the citizens of
Chicago are obliged to pay and con-
tinue to pay this excessive price
without receiving, directly or ind-
rectly, the benefits which should ac-
crue to this city and to the citizens
If the City and County Gas Com
pany will save 10 cents per thousand
on the price of gas the amount dur
ing the year runs up into the mil.
lions, and in addition, the city will
own one-third interest in the com.
pany and thereby receive yearly
revenue amounting to a very large
sum of money, while under the pres
ent arrangement they receive moth
