Year: 1868

page_text: LETTERS PATENT to Nicholas Demetrius Spartali, of Liverpool, in
the County of Lancaster, Steam Ship Agent, for the Invention of
"IMPROVEMENTS IN APPARATUS FOR BURNING HYDROCARBON OILS FOR THE
GENERATION OF HEAT."
Sealed the 8th December 1868, and dated the 12th June 1868.
PROVISIONAL SPECIFICATION left by the said Nicholas Demetrius
Spartali at the Office of the Commissioners of Patents, with his
Petition, on the 12th June 1868.
I, NICHOLAS DEMETRIUS SPARTALI, of Liverpool, in the County of
Lancaster, Steam Ship Agent, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN APPARATUS FOR BURNING HYDROCARBON OILS
FOR THE GENERATION OF HEAT," to be as follows:-
The Invention relates to the economic burning of hydrocarbon oils
as a fuel for generating heat.
In applying the Invention to a steam-boiler furnace I provide a series
of burners formed say of thimble-shaped tubes open at their upper ends,
and communicating with each other by horizontal branch pipes.
burners may be supplied with central air pipes if found desirable, and
The

page_text: they will receive the supply of hydrocarbon oil from a reservoir or pump
connected with the apparatus. The burners may be severally surrounded
with a shallow annular trough supplied with hydrocarbon oil, the
ignition of which will heat the oil in the burners and cause it to give off
a regular supply of vapour for ignition. The series or group of burners
may be contained in a tray or frame which will take the place of the
furnace fire-bars. A fan or blower may be used to drive forward and
intensify the flame so as to increase its evaporating power.
SPECIFICATION in pursuance of the conditions of. the Letters Patent,
filed by the said Nicholas Demetrius Spartali in the Great Seal
Patent Office on the 12th December 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, NICHOLAS
DEMETRIUS SPARTALI, of Liverpool, in the County of Lancaster, Steam
Ship Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of June, in the year
of our Lord One thousand eight hundred and sixty-eight, in the
thirty-first year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Nicholas Demetrius Spartali, Her
special licence that I, the said Nicholas Demetrius Spartali, my ex-
ecutors, administrators, and assigns, or such others as I, the said
Nicholas Demetrius Spartali, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and
at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN APPARATUS FOR BURNING
HYDROCARBON OILS FOR THE GENERATION OF HEAT," upon the condition
(amongst others) that I, the said Nicholas Demetrius Spartali, my
executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said Nicholas Demetrius Spartali, do
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascer-
tained in and by the following statement, reference being had to the
Drawing hereunto annexed, and to the letters and figures marked
thereon (that is to say):-
The Invention relates to the economic burning of hydrocarbon oil as
a fuel for generating heat.
The accompanying Drawing illustrates the application of the Invention
to the generation of steam in steam boilers, but it will be obvious that
the Invention is equally applicable for the generation of heat for other
purposes.
The
Fig. 1 shews in transverse vertical section an arrangement of apparatus
for burning liquid fuel in the furnace of a waggon boiler.
apparatus consists of a series of burners formed of thimble-shaped
tubes a, a, open at their upper ends and communicating with each other
by horizontal branch pipes b, b. The burners are supplied with central
air pipes c, c, to admit air to the centre of the flame of each burner, and
the supply of hydrocarbon oil is received from an elevated reservoir or a
force pump connected with the apparatus. The burners are severally
surrounded with a shallow annular trough a supplied with hydrocarbon
oil, which being ignited on starting the apparatus will quickly heat the
oil in the burners sufficiently to cause it to give off a supply of vapour
for ignition to do the work of the furnace. The series or group of
burners is contained in and fitted to a tray e, e, which takes the place of
the furnace fire-bars, and the central air pipes rising up from the tray
will admit air to their respective burners, as indicated by the arrows.
Instead of heating the burners by the use of hydrocarbon oil supplied
to shallow annular trays I may effect the same object by surrounding
the burners by hot water supplied by a donkey engine to a supplementary
boiler which may be brought into communication with the main boiler
when the apparatus has got into working order. This modified form of the
apparatus is shewn at Fig. 2, where it will be seen that the burners are
sunk as it were in a shallow water chamber or supplementary boiler f.
This water chamber serves the purposes both of the troughs d, d, and the
tray e, as it forms a connection between the burners and constitutes a
frame for supporting them besides containing the heating medium for
volatilizing the hydrocarbon oil.

page_text: A further modification of the Invention is shewn in Fig. 3, which
represents in sectional elevation a vertical steam boiler heated by a
single burner constructed on an enlarged scale. The bottom plate a of
the boiler forms also the bottom of the burner; the supply of air to
which is by a central pipe b, as in the above-described examples. The
central flue c of the boiler forms at its lower end the periphery of the
burner, and it is continued upwards (slightly contracting like a thimble)
until it reaches the water level where it contracts to a cylindrical form to
give steam space to the boiler, and extends through the crown to dis-
charge the gases of combustion into the air. The burner is supplied
with oil in regulated quantity from a reservoir or pump, and it may be
heated at starting by applying ignited shavings thereto.
Fig. 4 shews a somewhat similar arrangement as applied to a
horizontal boiler, the flues which pass directly through the water space
forming the outer periphery of the burners.
In all the above-described arrangements a fan or blower may he
used to urge and intensify the flame so as to increase its evaporating
power.
Having now set forth the nature of my Invention of improvements
in apparatus for burning hydrocarbon oils for the generation of heat,
and explained the manner of carrying the saine into effect, I wish it to
be understood that under the above in part recited Letters Patent I
claim, effecting the economical burning of hydrocarbon oils as fuel by
means of burners constructed and operating as above described.
In witness whereof, I, the said Nicholas Demetrius Spartali, have
hereunto set my hand and seal, the Tenth day of December,
in the year of our Lord One thousand eight hundred and sixty-
eight.
Witness,
JNO. S. KEELING.
