Upsets Accepted Laws.


1.-The new system Of combustion oper-
upsetting the accepted laws governing
combustion in furnaces, boilers. etc. in
that the air necessary for combustion
Is admitted to the fire chamber from
the top of the chimney or smokestack,
instead of in the usual manner, at draft
openings beneath the CRATES. In opera
ton, after the system has been in
stalled. bottom drafts are closed tightly
and all of the draft flows down the in
sidewalks of-the chimney or smoke
stack This is accomplished by the in
staliation inside the top of the stack of
. simple tubular or rectangular device,
carefully measured to leave an air pas
sage of the required width between the
inside OF the chimney or smokestack
walls and the outside of the device. The
shape Of the apparatus depends on the
round stack or rectangular In a fiue of
that shape. while the width of the air
passage between the inner walls of the
hue and the apparatus is governed by
the size, height. etc. of the stack or
chimney.
As. demonstrated in tests conducted
with models. as well as in practical
tests Of full-sized apparatus. the device
creates partial vacuum just above
the top of the chimney or flue and a
walls and the apparatus, bringing a
current of warmed air to the fire
chamber of the furnace or boiler,
which results in complete combustion
of gases In practical operation, it is
claimed, this creates a greater degree
Of heat from the use Of a much smaller
iQuantity OF fuel; consumes the coal
completely, leaving no cinders or
sclinkers. and only a small quantity Of
practically impalpable ash; leaves no
carbon or SCOT deposits in either fur
mace or hue, eliminates smoke almost
entirely and makes practicable the use
of cheap coal, bituminous slack, Ignite
or any kind of coal the use of which is
impossible under ordinary means OF
combustion because OF the dirt, smoke
or other Inconvenience. ~.
Cuts Deep Into Coal Bill.
In actual operation the use of the
Sew system of combustion results, II
Is asserted. in the generation from a
Sinsle ton of coal of any kind of as
fauch heat as under ordinary methods
f,f combustion would be obtained from
ton and a quarter to two tons OF
frst-class coal.
The system is applicable to locomo-
Ewes and to steamships of all classes.
81 Is asserted, and men interested in
bringing the system to the attention of
BE fuel administration claim tina. ex-
&austive tests on locomotives and On
he boilers of steamships have proved
tuel: while, as regards steamships, the
practically complete consumption of
Smoke does away with one of the fac
tors that have figured largely in the
destruction of shipping by German T.
boats and raiders. Elimination of trail
ing smoke clouds from a steamers fun
nels. 1t is stated, which accompanies
the use of the new system, ma kes such
vessels invisible when below the hori-
ION. where. with tunnels belchins
clouds of black smoke, the vessels car
be located when no part shows above
the curve of the ocean.
Use of the system has been offered tc
the government, for installation or
warships, Transports freighters ant
other craft, OF. in any other way, the
offer being unconditional and made, ac.
cording to statements of interested
persons. In spirit Of patriotism ant
desire to aid the government in an.
way possible in successful prosecution
Of the war.
