A WONDERFUL INVENTION,
DIR, Blanchard's Perfect Com
buStiOn Stove

which l. Also II Great Improvement
from ~ sanitary standpoint over the
Present system.
The International Improved Combustion
company has been formed at Middlebury
to put the Blanchard sanitary house heat
ing system on the market. Many people
will remember the interesting article pub
lished in The PhDniX several months ago
about the perfect combustion stove invent
ed by DR.. Virgil Blanchard of Middlebury,
a native of Gullford, and brother Of Mrs.
f. A. Wells OF Brattleboro. Dr. Blsnch-
ard has made further improvement in his
wonderful invention since then. His sys-
TEN not only gives perfect combustion of
fuel, furnishing heat at fractional cost of
any other system, but it does this without
taking the vtalizng properties out of the
air. One of Dr. Blanchards inventions is
now in practical operation at the home Of
Allan Calhoun in Middlebury
In an ideal system of house heating the
following characteristics and elements are
demanded: On Total or perfect combus-
ton of all varieties of fuel; (2) dstribu-
ton of an ample volume of fresh, pure,
mildly-heated air, containing its full quota
OF ozonzed oxygen for the purpose Of ven
/ tilation; 90 an efficient steam heating APP
paratus for supplying the necessary heat IN
addition to the heat supplied by the pure,
mlldly-heated, ozOnized air; % no posi-
/ bic danger of contamination OF the heated
air 10y the deadly dittusible gaseous poison,
/ carbunic oxide (CO): (jl reduction OF the
temperature OF the terminal gases from the
boiler 10y utilization OF their heat to a
standard closely approNlmatng the heat OF
/ the animal body l6D reduction of the TEN
perature OF the external walls of the fur
/ mace by utilization OF its heat TO a stand
ard closely approXimatihG the heat of the
animal body.
Tina. all these ideal characteristics and
/ elements are exhibited in the Blanchard
sanitary perfect cumbus ion house-heatiuc
system a candid. critical inspection Of the
plant in operation at Mr.. Calhoun's will
demonstrate. That total or perfect com
bustion of fuel supplied To- the furnace Is
realized repeated analysis Of terminal
gases from furnaces constructed on the
same principle concusively demonstrates.
Also. the fact that a given weight OF fuel
in this furnace does approximately two
and one-half times the duty that the same
weight will do in the ordinary furnace is a
practical demonstration of the fact of its
perfect combustion. That an ample vol.
ume of pure, fresh, ozOniZed air is suppl
ed as an auxiliary to the steam heat for the
purpose of ventilation, is apparent to the
observer That the heat OF the terminal
gases from the furnace before they reach
the chimney, and also the heat Of the eX.
teInal or radia;ing surface OF the furuac,
is reduced TO a standard closely approx
mating the heat Of the animal body may
also be observed. That there is no admix.
ture OF the deadly ditfusible gaseous poi.
son, carbonic oxide, with the air employed
for heating purposes IN this invention is
rendered certain from the fact that in the
perfect combustion of fuel this gas, which
is only an unburnt fuel gas, is burned and
reduced to heat by its reduction TO carbon
ic acid gas &C. on.
BY a happy combination in this inven.
ton of the hot-air system with the steam
system of house heating, in which the
high temperature region in the furnace i,
used for the generation of steam and il,
low temperature region for heating the air,
the hitherto insurmountable difficulties in
the production of al ideally perfect SAM
tary system of house-heating vanish as il
by magic, while at the same time perfect
results in economy in fuel are realized
BY locating the air-heating region in the
furnace in this invention external to the
steam-heating region and separating tn,
two by massive, gas-impervious walls, the
temperature in the former region never eX.
ceeding 800 degrees f., the pure, fresh
ozonized air from the outside atmospher,
can never suffer deterioration. while al
the same time the loss of heat by outward
radiation is etfectualy guarded agains
from the inner high temperature region by
its location within the low temperature Re
gion, the massive separating walls between
them serving as a cOpious reservoir fol
heat to assist in the process OF combustion
and to afford surplus at night with d.
mnished activity in the process of com
bustlOn. The method employed in utiliz
ing the heat of the terminal gases from
the steam boiler is as unique in character
as it is direct and practical in application
and can only be appreciated by witnessln.
the practical operation OF the invention.
In addition TO the house. heating plan
Just described, the inventor, Dr. Blanch
ard, has achieved an equal success in IN,
combustion Of gas, either of the natural
fixed, heating or atmospheric variety A
room heating gas stove of DR.. Blanchard
invention is now on exhibition at the stor,
of the firm OF Calhoun ~ Stewart in Mid
dleburY. Scientific tests of this stove witt
