plant to determine the amount. and
character of gas produced per pound
or ton of Ignite used. The by-pro-
ducts are carefully saved and examin-
ed. The amount of gas is determined
from each coal and then this gas Is
analysed and tested for its calorific
value. After this has been done the
gas is burned as an illuminant in open
burners and with the mantle and Its
light giving power determinedin COM
parison with other gases, tits then
consumed in variety of heating
burners and its behavior under differ
ent conditions and its heating power
observed. In this work the idea has
been to combine the scientific tests
and the practical uses in such man
ner that the conclusions NAV be borne
out by the daily uses to which the gas
will be put for the various industrial
purposes. -,
The gas produced for heating and
lighting purposes shows in most cases
a high per cent Of light hydrocar-
bons, particularly methane, and is
consequently an excellent heating gas.
There is comparatively little of the
heavy hydrocarbons and therefore mo
trouble in condensation or clogging of
burners when the gas is subjected to
the usual publication. @55
The quality and character Of the
gas quality varies materially with the
different processes o r notifications
which are used In its production, but
in most cases it is not difficult to Sc
cure a gas which will compare favor
ably for heating purposesk with, the
average city gas. From the tests
thus far made it would seem that at
least in tue western part Of the state
a heating and lighting gas may be
produced economically, having a cal
orific power Of from 600 torso BIT.
u, per cubic foot. %
For lighting purposes the gas pro-
duced from Ignite. by several meth
DDS used here in the laboratory, has
proven very satisfactory when burned
with a mantle of the Welsbach type.
OF course the Welsbach or mantle
type OF burner depends largely upon
the heating power of the gas for its
efficiency as light producer. BY this
method of utilizing the gas excellent
results may be obtained from the lig-
mite gas. The gas. burns freely with
a strong light and a clean fame which
seems we'll adapted to the mantle.
The gas does not give as good light
ing results with the open tip burner
unless the method OF production is
slightly modified and this there would
appear to be no serious difficulty In
doing. However, the use of the man
tie. in the opinion of the writer, r.,
with most gases, more satisfactory
and more economical for ordinary
purposes provided the gas used 10 OF
suitable character.
While tne work has not been car.
ried far enough at this time to give =
detailed statement CT the tests and re-
suits, still it seems evident from what
has been said that good practical
method of producing gas from Ignite
for heating and lighting may be 10
cured as a final result of these inves-
LEGATIONS being carried, on at the
school of mines. II this can be dem
onstrated it will prove of great value
ESTE nlly to the western part OF
the state. ,@.
The gas for heating and lighting of
which we have just been speaking,
can be utilized for power purposes.
but must not be confused with the so-
called power producer-gas which Ii
made in quite different manner.
In the regular process now used for
the manufacture of illuminating gas
from coal there is left q residue, gem
orally known as coke. which has con-
siderable market value. Heretofore
