Improvements in Apparatus for Simultaneously Burning both the
Light and Heavy Portions of Vaporizable Oils at one Burner.
A communication by GEORGE HENRY HARVEY, Mechanical Engineer, GUSTAVE
FRANCIS PERRENOND, Merchant, JAMES GETTY the Younger, Merchant, all
of Pittsburgh, in the County of Allegheny and State of Pennsylvania, and
GEORGE DELAYNES BAYAUD, Merchant, of New York, in the County and
State of New York, United States of America.
1, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6 Bank Street,
Manchester, both in the County of Lancaster and 323 High Holborn, in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
It is the object of the present invention to provide apparatus for simultaneously
burning both the light and heavy portions of vaporizable oils at one burner without
the use of a special atomizing blast.
The accompanying drawing illustrates, and diagrammatically in part, this improved
apparatus.
Numeral 1 indicates an air compressor, 4 an air conduit, 2 a by-pass pipe, 3 a
furnace for heating the air conduit 4, and 4' a pipe for carburetted air, 5 an oil
vessel, 5 a carburetter, and 51 an oil receptacle the use of which is optional.
These several parts may be of any approved construction, and suitable cocks and
other customary adjuncts will be used as required. 6, 6, indicate branches of the
hot air conduit which extend to near the bottom and have there numerous fine
perforations to thoroughly distribute air in the lower strata of the oil.
The hot air promotes vaporization of the oil and having a common temperature
therewith the vapor will readily burn. Instead of heating the air before its
introduction to the oil, the latter may be heated as by a steam coil 3¹ and it may
thus be made a medium of heating the carburetted air.
The bottom of the carburetter is made to communicate with a burner 7 by means
of a pipe 8 for the purpose of conveying to it the less vaporizable carbonaceous
residuuin which would otherwise accumulate in the bottom of the carburetting oil-
holder. The air pressure maintained in the carburetter tends to force the heavy
oil to the burner and its effect is aided by the eductive action of the carburetted
air forced through the burner valve or the regulator whereby the flow of heavy
or highly carbonaceous oil can be adjusted to supply a suitable quantity to avoid
the production of a smoky flame. 9 indicates a valve for regulating the flow of
carburetted air. For this purpose the ordinary needle valve used in vapor burners
for refined oil is not the most suitable for the reason that it would be clogged by
the impurities of the crude oil. It is characteristic of this improvement that
heated air under pressure is passed through oil and mingled with its vapors and
forced to the burner, the residual and more carbonaceous portion of the oil being
simultaneously forced by the air pressure to the same burner and there vaporized
or atomized, and mingled with the carburetted air and burnt therewith.
By the present improvement heated oil and air are supplied to the burner and the
supply of cach is positively and independently regulated. The air is also
carburetted and independently of the burner, no part of the heat of the latter being
necessary for the purpose. A more uniformly heated and intimate mixture of
carburetted air and heavy oil vapor is secured at the burner than by any prior

page_text: apparatus known and crude and other oils can be entirely consumed without the
aid of a steam jet or other like subsidiary device.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is :-
1. The combination of an oil-holder, an air-forcing device, an air conduit for
conveying air to said oil-holder, means for mechanically distributing the air in
the oil, a burner, and conduits connecting the upper and lower parts respectively
of the oil holder with the burner whereby carburetted air and residual oil may be
conveyed to said burner, substantially as above described.
2. The combination of an oil holder, an air forcing device, an air conduit for
conveying air to said holder, a heater for heating the air, means for mechanically
distributing the air in the oil, a burner, and conduits connecting the upper and
lower parts respectively of the oil holder with the burner whereby carburetted air
and residual oil may be conveyed to said burner substantially as described.
3. The combination of an oil holder, an air forcing device, and air conduit for
conveying air to said oil holder, means for mechanically distributing the air in the
oil, a burner, conduits connecting the upper and lower parts respectively of the
oil holder with the burner whereby carburetted air and residual oil may be conveyed
to said burner and an independent regulating valve in the oil conduit, substantially
as above described.
4. The combination of an oil holder, an air forcing device, an air conduit for
conveying air to said oil holder, means for mechanically distributing the air in the
oil, a burner, conduits connecting the upper and lower parts respectively of the
oil holder with the burner whereby carburetted air and residual oil may be
conveyed to said burner and independently regulating valves in the oil and vapor
conduits respectively located at the burner and adapted to positively close either
wholly or partially the oil and vapor passages, substantially as above described.
