Especial Dispatch to the Enquirer.l
New York, October 2O.-Mr. S. G.
Salisbury, a mechanic, has been at
work for twenty years on plan to
utilize petroleum for fuel in produc-
ing steam. He has hit it, and is in a
fair way to make fortune. 1t was
tested in the Brooklyn Navy Y ard on
Saturday, and was found to work to
the utmost satisfaction of the officers
who inspected it. The furnaces were
in full blast, but no smoke was visible
Great volumes of white steam rolled
away from the pipe, but no coal was
thrown upon the fire below. 1t hao
the look of all effect without cause.
:.The most wonderful sight l have
| ever SEEM" the veteran engineer Ish-
erwood said. "It revolutionizes the
iron and steel manufacture the world
over," one of the largest iron men of
the country exclaimed. 1T opens a
new era in glass manufacture. We
shall soon have glass roofs on our
| houses, and French plate will be as
cheap as common window-glass,' said
| q large glass.maker.
The results were so extraordinary
in the perfect combustion attained, in
the intensity of heat quickly produced
in the enormous pressure of the SUI
perheated steam, in the astonishing
evaporation of water, in the freedom
from dust, cinders, sulphur and all
impurities, that these experts at once
realized that q revolution in all de-
partments where steam is used must
occur Immediately.
The fuel is made of the residue Of
petroleum and coal-tar, which is mix
ed to about the consistency of molas-
ses. 1t is conducted from the barrel
to the furnace by means of small
gas-pipe. At the end of this pipe as
it enters into the door of the furnace
is funnel shaped apparatus. AS the
fuel enters this funnel it comes in con-
tact with a current of highly super
heated steam, which atomizes the liq-
uia so that it leaves the machine. 1t
induces the required amount of oxy-
hn int of
ignition. Thus the atomized fuel shoots
in fierce but delicate spray, into the
blazing furnace. The brick arches of
the great furnaces are kept at a white
heat, and pure white flame flashes
along the whole length, registering a
heat of 5000 degrees, melting pig iron
in ten minutes, and making liquid
glass in two hours instead of sixteen.
All that there is to maintain this ex-
traordinary heat is the slight spray
darting in from the little furnace,
which comes just within the door. 1
can send this intense white flame from
the battery to Grace Church if 1 have
furnace arch that long, said the in
ventor.
The amazing scope of this new dis
covery may be estimated from its ef-
feet upon the oil trade alone. Mr.
Salisbury says he is about to make q
proposition to the producers and the
United Pipe Lines for permanent
contract to take from them at Pitts
burgh all of their surplus and all theil
distillate tar napthas at price that
will give the producers fully so pei
cent. profit, and also pay the pipe lines
for piping it to Pittsburgh. The ocean
steamship business will also feel the
effect of this revolution in steam-pro
ducing fuel. Experiments already
made show that in single trip across
the Atlantic saving of about $4,000
will be effected in freight room alone
as the space now taken up tor 500 tons
of coal will be used for freight.
But the greatest achievements of the
new system will be in iron making
Said the leading representatives O
this interest: 'This is the grandes
achievement of science in this age and
this inventors income, even on very
small royalties, will be greater than
that of any living capitalist. With
the mechanism invented by Mr.. Sails
bury blast-furnace of thirty tons pei
day will convert its liquid iron into

steel at cost so trifing that it enhan-
ces the value of pig-metal 100 per
cent.
Sulphur and carbon, the two deter.
iorative elements that are present in
all the wrOught-lron now made, are
utterly cast out by this new process
In the Salisbury Furnaces the pig
metal is melted to a thin liquid in fif-
teen minutes. 1t is then drawn off in
to a second furnace, one foot lower
than the first. The second furnace is
Immediately charged with continu.
Gus sheet of hot air, and superheated
steam Of 1000 degrees and immense
pressure, which keeps every particle
of the liquid metal in agitation, and
burns out the carbon utterly in from
eight to ten minutes, when it is ready
for the puddler. AT no time in this
operation can any cold air come in
contact with the liquid, and conse.
quently every particle becomes unit
ed. In the two melting processes ev-
cry trace of sulphur is taken up. The
instant the metal is run Off into the
second furnace the first is filled with
pigs When number two is taken out
by the puddler the new lot is ready to
run into the second furnaces and so OF
in ceasless alienation.

the method where coal is used as fuel
