The New System by Which Every
Atom of Fuel is Consumed.

Atom OF Z ueI IS consumed.
According to the Berlin CORES
! pendent of the London Standard,
the problem of smOkeless COmbus-
ton of coal seems at last to be
solved by a newly patented process
which is exciting an immense SEN
satiOn in Germany. The patent
has been taken out by company,
which has already made contracts
with number of large commercial
and industrial cOncernS-amOng
others with the North German
Lloyd, the Hamburg American
Packet company, Schichau, and the
Vulcan works at Stettin-fOr the
introduction of its new system Of
firing.
In the construction of their new
firing apparatus, the patentees
have departed from all the
methods hitherto employed. The
coal is no longer burned in Jumps,
but is reduced to powder by means
of the ordinary centrifugal mills.
The new system, which is called
"automatic and smokeless coal
dust firing" is extremely simple.
At the place where hitherto the
coal was introduced into the fire
CRATE, that is to say, at the furnace
door, there is a movable bear
shaped apparatus, consisting
principally of fire chamber
lined with fire brick. One Of
lNl ~ Of hn1
pear opens, in the direction
of the axis of the boiler, into the
mouth of the hitherto employed
furnace, from which the fire CRATES,
fire bridges, ETC., have been re-
moved. The opposite aperture of
the hollow pear is intended to adj
nit a current Of air. BY means of
an ingenious automatic cOntriV-
ance, coal dust, supplied through a
funnel placed above the current of
air, is continually conveyed into
the current of air and thence into
the fire chamber, where it is i'm
mediately brought into cOmbus-
ton by means Of the small fire
which is placed there. When this
has once taken place, the coal
dust conveyed by the current Ofair
continues to burn in one regular,
intense flame. The current Of air
which brings the coal dust into
the apparatus is regulated 50 as to
merely convey tint dust thithCr,
whereas the further supply Of air
NECESSARY for the combustion is
sent into the zone Of combustion
at right angles and in radiating
Jets. BY this arrangement tn" coal
dnSt and the air in the ZOnro of COM
buStiOn are intimately and thor
Oughly mixed, whilst the speed of
the current which introduces the
coal dust is diminished.
1t will thus be seen that the
combustion Of the coal which this
method produces is extremely
thorough, for each particle Of fuel
floats in the air and is brought in
to contact with the oxygen ncCeS-
SarV for its combustion, 50 that it
is totally consumed the moment it
enters the sphere Of combustion.
| he DIOOl vi us DtlllS lOldllN Noll-
Sumcd is seen in the fact that not
even trace of smoke is pcrccp-
tible. With the pressure of fin
ger the supply of coal dust and Of
draught can be perfectly regulated,
and thereby an cquablo generation
of heat secured.
Among the further advantages
of the new system Of firing may b
mentioned the diminished wear
and tear of steam boilers, the alb
sence of fire CRATES and fire bridges,
the ability to start or to stop the
fire instaneOusly, the absence of
heaps of cinders and ashes, and
the avoided necessity for high
chimneys. 1t is further claimed
that this method of firing is suit
able not only for steam boilers,
but also for all kinds of heating,
welding, smelling and burning
processes, that it can be used in
all sorts of manufactures, and that
by it not only ordinary coal, but
also brown coal, charcoal, turf
powder. etc, may be burned.
