That the smoke problem has been CON-
rle+elv solved no longer admits of doubt
This fact is being daily demonstrated in
this city upon the powerful boilers of Wey-
man Bros tobacco factory, between Sixth
and Seventh streets.
This wonderful furnace, known as the Nc
Kenzie Economic Smokeless Furnace, is
the invention of Douglass j. Mckenzie, q
well-known engineer of the Northwest For
wears Mr.. Mckenzie studied and expert
mented on the problem of constructing a
furnace that would not make smoke, but
would still do as much work as other fur
naces that had been apparently constructed
with view of making as much smoke as
possible He at last succeeded, and placed
the first furnace upon the plant of w. 5. u
J. B. Williamson, of Madison street, Chi
cago, six months ago. The results were
wonderful. AT Gage Bros, Wabash ave-
nue, the next furnace was built, and a
thorough fuel test made, showing that
in September and October last, without
the furnace in operation, Isl, ,005 pounds of
coal were consumed, and in November and
December following, with the furnace in
use, 1O1. .645 pounds of coal were burnt-a
saving of 49, 800 pounds, or 33 per cent,
made bv this furnace. Had the weather
been equal during the entire four months,
and the demands upon the furnace for fuel
the same, the result would have been even
more favorable 1t has recently been put
upon the Owings building, Dearborn and
Adams street; Mr.. J. Tierney u Co., IA
North Canal street; Yerkes' Northwest
Cable Road power house, and numerous
other places in Chicago.
The first furnaces built outside of Chicago
are the two now IN operation at Neyman
Bros. and one in course of erection for
Ur-us & Haclle, under the supervision OF
{. F jain, who is the General Manager
OF the Mckenzie Company in the East
Speaking Of the furnace yesterday, Mr.
jain said:
The principle upon which the Mckenzie
furnace is built is the one upon which smoke
experts and inventors have been working
Tor centuries, but they seem to have left it
for Mr.. Mckenzie to attain the results
aimed at. 1t is done in this way:
'The coal is thrown into the front of the
furnace. the end of an arch marking how far
in the fireman is to throw it. There it be-
comes coked, and the fumes and smoke pass
into an arch, the space beyond which is kept
iull Of the coal already coked. The heat
within this arch is intense. 1t requires
heat Of 5000 to consume the smoke and
cases. but this furnace has temperature
under the second a. ch of ,200O. The heat,
when II reaches the boilers, is evenly dis
Since the furnace has been in operation
At Wevman's great many engineers and
others have examined IL with amazement.
Among he callers the other dsy were the
ladies Of the Health Protective Association.
They were delighted with the furnace, and
considerably encouraged in their effort TO
abolish the smoke nuisance.
