the value of an apparatus which is well
worth the study of manufacturers, says
La Nature
Smoke may be more or less invisible,
but its composition is invariable. 1t Is
inside up of pulverulent matters, incom-
bustible gases, as nitrogen and amy
bride carhonic, combustible gases such
as oxide of carbon, hydrocarbides and
hydrogen These represent the struc-
ture of smoke. no matter how transpa-
rent it may be. The fact is, however,
that this heterogeneous mixture may be
burnt, familiar proof of which is given
in the paper horn, the smoke of which Is
ignited, but after this second combus-
ton the smoke is not again destroyed.
the exact point being TO make the smoke
disappear absolutely and to find some
means of making profitable use OF this
same destruction.
The method of NJ Tobiansky is as fol-
lows: First, filtration of the smoke to
rid it of pulverulent matters and OF the
condensible hydrocarbides; second,
carburation of the gases to increase
their facility of combustion. For long
time attempts have been made to filter
the smoke by Kidding it of its carbonic
acid and to do away with chimneys by
replacing them with an artificial
draught which sucks or draws back the
smoke. M. Tobiansky has combined the
two systems, and knowing that car
burated air produces an excellent gas
he carburated the smoke which had pre-
viously been filtered and drawn back.
The products OF the combustion thus
treated gave him new gas, which he
called ..pyrogas," and which does not
condense. For purposes of lighting.
heating and motor uses the method is
invaluable and permits the utilization
Of detritus Of all sorts.
The operator by means Of an instru-
ment of suction forces the smoke into
hitter filled with porous substance
drocarbide such as naphtha or petro-
leum. The porous matter is q combus-
tible; for example. coke. and we will see
In Z moment why this is 50. In passing
through the filter the smoke deposits
on the coke q portion of the hydrocar-
bfdes or tars which It contains, at the
same time becoming charged with the
vapor of the volatile hydrocarbides With
which the porous matter is saturated.
After filtration the smoke Is only COM
posed of combustiblc gases, such as
oxide Of carbon, hydrocarbide vapurs
and hydrogen, and OF incombustible gas,
rs nitrogen and carbonic acid.
BY this method NJ. Tobiansky obtains
from smoke of all sorts the greatest pos
sible profit, utilizing first the heat which
