Improvements in Oil Burners.
I, ALONZO NOTEMAN of 1521 Twenty second Street, Toledo, Ohio, United States
of America, Merchant, 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:
This invention relates to a novel apparatus for converting liquid fuel into vapor
or gas, and burning the saine, consisting in its essential parts of parallel plates the
adjacent surfaces of which are placed close together, and. a fluid supply pipe or
passage communicating with the space between the plates, said plates having an
extended area of heating surfaces between which the fluid is confined in its passage
between the plates and by which the liquid is converted into vapor or gas before it
issues from between the plates.
The invention may be employed under many circumstances where it is desired to
convert liquid into vapor or gas and burn the same. The invention is herein shown
as applied to a liquid fuel burner adapted for heating or cooking, and also as applied
to the furnace of a steam boiler.
The burner illustrated consists of metal plates which are placed horizontally or
substantially so and one upon the other together with a supply pipe which com-
municates with the space between the plates whereby the oil delivered through said
supply pipe passes between the plates from the pipe toward the periphery of the
plates and is therein vaporized or converted into an inflammable gas which issues
from between the plates at the peripheries of the latter.. The flame produced by
the admission of the vapor or gas serves to heat the plates and maintain them at
high temperature, the heating of the plates preferably being facilitated by means
of suitable deflectors arranged to direct the flames over the surface of one of the
plates.
In said drawings:
Figure 1 is a vertical, sectional view of an ordinary cylinder stove with the burner
arranged therein.
Figure 2 is a side elevation of the combustion chamber beneath the boiler, showing
the burner constructed in the form of grate bars.
Figure 3 is a plan view of the burner shown in Figure 2, showing the connection
of the oil feeding pipe with the burners.
Figure 4 is a cross sectional view on an enlarged scale of one of the duplex bars
taken upon line x-x of Figure 3.
A designates the combustion chamber, having walls B. C designates the burner,
as shown in Figure 1, consisting of an upper plate D, and a lower plate E, said
plates being of approximately the same area. F designates the oil supply pipe
leading from the source of supply (not shown) to the upper surface of the lower
plate E, whereby oil being fed through the pipe F is caused primarily to pass
between plates D and E and finds an exit at the peripheries thereof, whereupon
the oil being ignited the upper plate soon becomes heated, the heat is communicated
to the lower plate and thereafter the oil in its movement towards the periphery of
the plates is vaporized or converted into gas, and issues as such.
In order to concentrate the volume of air and deflect the same towards the upper
surface of plate D, I have shown in Figure 1 a cylinder G open at each end and
of somewhat less diameter than plates D and E and placed directly over said plates,
the cylinder terminating at its base with a concentric flange H of an area corre-
sponding to the size of the stove.
The cylinder is suspended within the stove by means of lugs I upon the inner
side of the stove and upon which the flange rests. When, however, the burner is

page_text: to be used in the furnace of a boiler the current of air being led from below the
series of plates D and E, the inner walls of the combustion chamber serve the purpose
of the cylinder shown in Figure 1.
In Figures 3 and 4 are shown the sections D and E of burner (, formed with
a circular opening K, Figure 3 showing this construction by having a part of one
of the sections broken away at y to also show the termination of the circular opening
near the end of the section.
This construction is desirable where a greater degree of heat is desired than is
necessary in an ordinary stove, as by this means the burner may be composed of a
number of sections and a corresponding number of air spaces K¹.
Oil is fed to each section by means of branch pipes F¹ leading from the oil supply
pipe F.
In Figure 2 the burner C is shown as inclined slightly from the furnace door to
the bridge wall L, which tends to cause the oil to gravitate towards the rear end
of the burner while being vaporized.
In operation, oil is admitted to pipe F, and flows to and between plates D and E
(as many of said plates being used as is desirable) and upon flowing to the edge of
said plates, is ignited, when the plates soon become sufficiently heated to generate the
oil into gas.
Air is admitted to the stove or furnace through the usual channel and
unites with the gas in combustion. Where the burner is composed of sections, the
air passes through the several spaces formed in sufficient number for this purpose, in
which event the cylinder and flange shown in Figure 1 may be omitted. This con-
struction is equally well adapted for stoves, ranges or other heating apparatus, as for
boiler furnaces.
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-A burner for converting liquid fuel into gas and burning the same, comprising
two parallel plates the adjacent surfaces of which are placed close together, and an
oil supply pipe communicating with the space between the plates, said plates being
formed to provide a narrow exit slot or opening at which the gas is burned, and
having an extended area of heating surface between which the fuel is confined in
passing from the supply pipe to the said slot or opening.
2: A burner for converting liquid fuel into gas and burning the same, comprising
two parallel plates one of which rests upon the other, and an oil supply pipe com-
municating with the space between the plates, substantially as described.
3-A burner for converting liquid fuel into gas and burning the same, comprising
two plates having their adjacent surfaces parallel and close to each other, an oil pipe
supplying oil to the space between said plates, and a burner casing surrounding said
plates and provided with a part or wall arranged adjacent to one of the plates and
operating to deflect or maintain the flames against or in contact with said plates,
substantially as described.
