Improvements in Apparatus for Burning Hydro-carbon Oil as Fuel.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent
Agents, Southampton Buildings, in the County of Middlesex, do hereby declare
the nature of this invention to be as follows:-
My invention relates to apparatus for burning hydrocarbon oil and especially
crude petroleum as a fuel to supply heat for making steam or other desired
purposes.
The
The apparatus constructed according to the present invention comprises an initial
combustion chamber, the bottom of which is preferably formed of a pan.
bottom of this pan may have a covering of asbestos, mineral wool, or other
substance such as has heretofore been employed in devices of this character. Oil
is fed into the combustion chamber by a suitable feed, preferably acting by gravity,
and is ignited therein in any well known manner. Oxygen to support the necessary
combustion in the chamber is admitted through an air opening leading thereto.
This air opening in practice should be provided with a suitable damper to regulate
the amount of air supplied.
The oil ignited and burning in the chamber gives off vapour or gas, and an
outlet preferably circular in form is provided in the chamber, through which outlet
the gas or vapour may pass on its way to the work. To complete the combustion
of the vapour or gas formed in the chamber, I provide an air pipe, the outer end
of which communicates with the outside air or other source of oxygen. This air
pipe enters the chamber and its inner end is arranged substantially opposite the
outlet opening, but at a distance therefrom sufficient to leave room for the passage
out of the, vapour. This air pipe being thus located opposite the outlet discharges
a supply of air centrally into the body of the vapour as it leaves the vaporizing
chamber, so that the vapour of the oil, and the oxygen coming through the passage
way will be brought into thorough contact.
Beyond the outlet a second pipe is provided which serves to hold the oxygen
and oil vapour together and to intermix them as they pass through it to the point
where the work is to be done, which may be the fire-box of an ordinary horizontal
tubular boiler.
The apparatus thus far described has been found in practice to give commercially
good results, but at the same time it is defective in that there is a tendency to the
deposition of carbonaceous matter in the form of soot around the edges of the
outlet and also along the walls of the air pipe. This deposit, if it increases
sufficiently, will interfere with the most effective working of the apparatus, but its
formation around the edges of the outlet may be obviated by the use of an
additional air supply which may consist of tubes communicating at one end with
the atmosphere and with their inner ends so located that air passing through them
shall be supplied to the outside of the mass of vapour as it passes out annularly
between the interior body of air supplied through the air pipe and the exterior
envelope of air supplied through the tubes.
In addition to the air supplies already mentioned a third may be provided, entering
the said air-pipe at or near its end next the outlet. The introduction of air at this
point is found to check the tendency to deposit soot upon the inner walls of the

page_text: air pipe. The various air inlets should in practice be provided with suitable
regulating dampers.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Burning Hydro-carbon Oil as Fuel.
1, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent
Agents, 45, Southampton Buildings, in the County of Middlesex, 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:-
My invention relates to apparatus for burning hydro-carbon oil and especially
crude petroleum as a fuel to supply heat for making steam or other desired
purposes.
In the accompanying drawings I have shown how my said invention may be
conveniently and advantageously carried into practice.
Figure 1 is an end view of my improved apparatus.
Figure 2 a vertical longitudinal section of the same.
Figure 3 is a similar view of the apparatus arranged in connection with a steam
boiler of well known type.
The apparatus constructed according to the present invention comprises an
initial combustion chamber A, the bottom of which is preferably formed of a pan B.
The bottom of this pan may have a covering of asbestos, mineral wool, or other
substance such as has heretofore been employed in devices of this character. Oil
is fed into the combustion chamber by a suitable feed, preferably acting by gravity,
as shown at C and is ignited therein in any well known manner. Oxygen to
support the necessary combustion in the chamber A is admitted through an air
opening a leading thereto. This air opening in practice should be provided with a
suitable damper to regulate the amount of air supplied.
Το
The oil ignited and burning in the chamber A gives off vapour or gas, and
an outlet D preferably circular in form as shown, is provided in the chamber A,
through which outlet the gas or vapor may pass on its way to the work.
complete the combustion of the vapor or gas formed in the chamber A, I
provide an air pipe F, preferably arranged as shown, the outer end of which
communicates with the outside air or other source of oxygen. This air pipe
enters the chamber and its inner end is arranged substantially opposite the outlet
opening D, but at a distance therefrom sufficient to leave room for the passage out
of the vapor.
This air pipe being thus located opposite the outlet discharges
supply of air centrally into the body of the vapor as it leaves the vaporizing
chamber, so that the vapor of the oil, and the oxygen coming through the passage
way E will be brought into thorough contact.
a
Beyond the outlet D a second pipe F is provided which serves to hold the
oxygen and oil vapor together and to intermix them as they pass through it to the
point where the work is to be done, which in Figure 1 I have represented as the fire-
box of an ordinary horizontal tubular boiler.
The apparatus thus far described has been found in practice to give commercially
good results, but at the same time it is defective in that there is a tendency to the
deposition of carbonaceous matter in the form of soot around the edges of the
outlet D and also along the walls of the air pipe F. This deposit, if it increases
sufficiently, will interfere with the most effective working of the apparatus, but its
formation around the edges of the outlet D may be obviated by the use of an

page_text: additional air supply, which may consist of tubes GG G, communicating at one
end with the atmosphere and with their inner ends so located that air passing
through them shall be supplied to the outside of the mass of vapor as it passes out
annularly between the interior body of air supplied through the air pipe F, and
the exterior envelope of air supplied through the tubes GG G.
In addition to the air supplies already mentioned, a third may be provided,
entering the said air pipe at or near its end next the outlet D as shown at H.
The introduction of air at this point is found to check the tendency to deposit soot
upon the inner walls of the air pipe F. The various air inlets should in practice
be provided with suitable regulating dampers.
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 correspondent, I declare that what I claim is :-
First. In an apparatus for burning hydro-carbon oil, an ignition chamber A, an
air supply a thereto, an outlet D from the said chamber, a main air supply pipe
entering the said chamber and terminating opposite the said outlet, a pipe F outside
the said chamber, the said pipe having one extremity opposite the said outlet and
leading to the point where the products of combustion are to be discharged, and
a suitable oil supply whereby oil may be fed into the chamber, substantially as
set forth.
Second. In an apparatus for burning hydro-carbon oil, an ignition chamber A,
an air supply a thereto, an outlet from said chamber, a main air supply pipe entering
the said chamber and terminating opposite to the said outlet, an additional air
supply arranged around the said chamber as described whereby air may be
discharged upon the outside of the vapor passing from the said outlet, a pipe F
outside the said chamber the said pipe having one extremity opposite the said, out-
let and leading to the point where the products of combustion are to be discharged,
and a suitable oil supply whereby oil may be fed into the chamber, substantially
as set forth.
