PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Burning Liquid Fuel.
I, AUGUSTE QUENTIN of 49 Rue Antoine Dansaert, Brussels, in the Kingdom
of Belgium, Civil Engineer, do hereby declare the nature of this invention to be
as follows:-
My invention relates to apparatus for. burning liquid fuel. Briefly stated the
nature of my invention may be said to consist in a burner composed of a nozzle
placed near to or surrounded, or partly surrounded by a body of metallic shavings,
turnings or porous or perforated material or incombustible fibrous material
contained in a suitable chamber, the flame from the nozzle heating the walls of
said chamber and serving to vaporize oil which is admitted to the metallic
shavings or like material in the chamber from a suitable reservoir and when
vaporized passes to said nozzle where it mixes with the air and produces a very
hot flame.
A burner constructed as above may be arranged in various ways and a collection
of same may be employed in various forms and for various purposes, such as for
heating steam boilers, and in furnaces or heating apparatus generally.
One form of burner that I prefer to employ when a single one is required
consists of an annular chamber containing the metallic or other material, the
chamber being connected across the internal opening below by a pipe on which is
mounted a nozzle having a small bore, the flame from such nozzle passing up the
central opening and heating the chamber surrounding same, the vapor delivery
pipe and nozzle being thus kept hot so that no condensation of the oil takes place.
The nozzle may consist of a tube having a small block held in the opening of the
same by screwing or otherwise, such block having a capillary opening and an
inverted conical end entering the end of the tube, the object of the inverted end
being to prevent dirt carried up with the vapor passing into the opening or bore,
as such particles of dirt will strike the sloping walls of the cone and fall back into
the tube.
Instead of placing the burners on or beneath a tube forming the internal wall of
a chamber, a number of tubes and burners may be arranged in a chamber filled
with the metallic or like material.
In the case where it is desired to heat a flue or furnace a number of burners
constructed as above may be arranged in an annular form or a form approximating
thereto, the air which mingles with the flames of same being drawn in through the
central opening, so that it becomes heated before passing to the burners. Means
may be provided for withdrawing the burners and pipes leading thereto for the
purpose of reaching same for cleaning.
In some cases it may be desirable to heat the pipes in which the oil is passing
from the reservoir to the vaporizing chamber and this may be done by arranging
he pipes so that they come near to the flame of the burners.

1, AUGUSTE QUENTIN of 49 Rue Antoine Dansaert, Brussels, in the Kingdom
of Belgium, 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:—
My invention relates to apparatus for burning liquid fuel.
The object of the invention is the production of a burner for heavy liquid
hydrocarbons such as ordinary petroleum, schist, shale oils and others, consuming
a mixture of the developed gas with air in a similar manner to the Bunsen burner,
but distinguished from those heretofore employed by the more perfect consumption
of the elements. In other words the burner operates without producing the tarry
condensation which up to now has constituted an obstacle to the general use of
such burners.
In the accompanying drawings forming part of this specification
Fig. 1 is a vertical section of a single element or burner.
Fig. 2 is a plan.
Fig. 3 is a vertical section on a larger scale of the nozzle or burner proper.
Fig. 4 is a transverse section of a battery of elements or burners of a suitable
shape for the interior of a boiler furnace flue.
Fig. 4 is an elevation of a part of the exterior of same.
Fig. 5 is a transverse section on a smaller scale of a boiler fitted with this
arrangement, and Fig. 6 is a longitudinal section of same.
A single element or burner is composed of a casing forming the chamber or tube
for the gasifying of the hydrocarbon on its way to the nozzle. Such casing is
formed of two concentric cylinders E and C having between them an annular
space closed at both ends by the wall connecting the two cylinders. Such space
forms the gasifying chamber M into which the hydrocarbon is admitted by the
tube T attached in any suitable manner to the opposite end of the chamber to
which the nozzle B is carried. This nozzle B is secured to a cross pipe D in the
interior of the cylinder C, such pipe having a passage 7 opening at both ends into
the space M and communicating with nozzle B. The space M is filled with finely
divided material preferably metallic chips or turnings closely packed so as to leave
very narrow interstices through which the hydrocarbons filter, thus covering the
chips with a very thin coating which is vaporised and gasified as soon as the
chamber reaches the desired temperature. It is in order that this high temperature
may be reached in the said space that the burner is placed at the bottom or end of
the cylinder so that the flame develops entirely, or almost so, in the interior of the
cylinder and traverses it from end to end. By this arrangement not only is perfect
gasification obtained, but it is also very abundant since the thin coating of hydro-
carbon is very extended and is taken up quickly so as to produce a very rich
flame burning blue with the air drawn in the cylinder C through the lower end of
same.
The nozzle is screwed to or otherwise removable from the pipe D. It consists
of two parts, a tubular portion and a plug b secured in same in which is a small
capillary opening. The plug is conical at its inner end so as to prevent its
stoppage by dust or any particle which may be drawn in by the gas and which
instead of entering the passage will strike upon the coned end and be lodged in the
hollow which is formed with the wall of the burner.
With reference to the battery of burners shown in Fig. 4 it will be seen that an
individual casing for each nozzle is not employed, an external casing surrounding
all the nozzles being substituted so that the packed material receives the heat of

page_text: the flames on both sides and is thus exposed to about double the action or to the
maximum of the heat developed.
In the construction of the battery for an inside-fired tubular boiler two con-
centric cylinders are employed, between the walls P, P' of which, the nozzles or
burners are fitted up radially, the external surface of the battery being placed near
the interior of the flue which is surrounded by water contained in the shell G.
The feed pipe T may be led to the interior of the furnace so as to thoroughly
liquify the hydrocarbon before its, admission to the battery of elements to hasten
the work, and such pipe may be removable to allow its periodical cleansing from.
the tarry products which might eventually be formed therein since the hydrocarbon
is not volatilised in this as in the burners.
The air feeding the battery of burners is admitted in the centre by a tube or
flue O also exposed in part to the heat of the furnace so that the air is warmed
before mixing with the gas of the burners thus further helping the working of the
burner.
It is obvious that a battery of burners as above, or a single element may be of
any suitable shape, their construction being modified to suit the circumstances of
each case.
Having now particularly described and ascertained the nature of my said inven
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In apparatus for burning liquid fuel, an element or burner in which is
comprised a chamber containing a suitable finely divided material through which
the hydrocarbon passes, said chamber being heated through its length by the
flame from a nozzle at which is burnt the vapor so produced substantially as.
described.
2. In apparatus for burning liquid fuel an element or burner consisting of a
chamber containing a suitable finely divided material through which the hydro-
carbon passes, and a nozzle communicating with said chamber and surrounded by
same, said nozzle being placed at the open lower end of the chamber, substantially
as described.
3. In apparatus for burning liquid fuel the arrangement and construction of a
battery of the elements or burners set forth in the preceding claim, substantially
as described.
4. The arrangement and construction of the single element or burner substantially
as described and illustrated.
5. The arrangement and construction of the battery of elements or burners
substantially as described and illustrated.
