Improvements in Hydrocarbon Burners.
I, JOSEPH HENRY MATHEWS of No. 43 South Market Street, Canton, in the
County of Stark and State of Ohio, United States of America, Metallurgist, 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 improvements in hydrocarbon burners the object of
which is to provide a burner that will work under great pressure to produce an
interior heat for smelting purposes, the flame of which is not liable to be extinguished
or go out, that does not require a sublight, and that will not burn the gas inside
the burner.
In the accompanying drawings
:
Figure 1 represents a side view of a burner embodying my invention with a
portion cut away to show the upper end of the gas pipe and the form of the top
chamber, and
Figure 2 represents a central section of a reducer adapted to the top portion of
the burner.
Referring to Figure 1, A represents a supply pipe through which the supply of
hydrocarbon flows from the place of supply to the injector or vaporizing chamber A';
under high pressure a quantity is allowed to flow through the tube B and the pin
valve C, into the pan D formed about the lower portion of the burner; this over-
flow of hydrocarbon is fired to heat the burner to such a degree as to cause it to
atomize the hydrocarbon which will flow through the valve C into the mixing
chamber E below the burner chamber F.
I wish to call particular attention to the form and structure of these chambers as
it is upon this particular feature that the success of the burner depends. At a
distance below the upper end of the mixing chamber E, which is projected into the
burner chamber F, is projected a flange portion a that forms the bottom of the
latter chamber; from the outer edge of this bottom a is projected upwardly the side
or wall bon converging lines as shown, thus forming a truncated conical chamber
having a top opening that is of a less diameter than the bottom portion but larger
than the upper end of the mixing chamber E.
In operation the gas flows with great force from the upper end of the mixing
chamber in a compact form, enlarging but little as it passes out of the chamber at
which point it is ignited, no gas burning in the chamber when the burner is in full
operation. By the flow of the gas through the burner at such great speed, the air
is drawn from the lower corner portion c forming a partial vacuum which in turn
causes a counter current of air to flow a distance down against the inside of the
wall b between the wall and the upward flow of gas, that will turn and take into the
gas at a point below the point of combustion, by which an additional amount of
oxygen is supplied to enrich the gas with heating quality and to absolutely prevent
the extinguishing of the flame so long as there is a supply of hydrocarbon.
This burner is adapted solely for producing intense heat for smelting metals and
kindred purposes to be used under crucibles in smelting furnaces.
The intensity of this burner may be reduced by placing the reducing ring or
cap G in the upper end of the chamber F.

page_text: 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. The combination, in a hydrocarbon burner of the mixing chamber E, the
lateral injector A' and pipe leading from a hydrocarbon supply by which fluid
hydrocarbon may be injected into the chamber E under pressure, and the truncated
conical chamber F formed integral. with the chamber E, and the mixing chamber
near its bottom having openings for the admission of air to support combustion,
substantially as specified.
2. The combination in a hydrocarbon burner of the mixing chamber E, the
truncated conical burning chamber F at the upper end thereof, the lateral injector A¹
for injecting hydrocarbon under pressure into the mixing chamber, the tube B,
valve C and pan D whereby a hydrocarbon-in-regulated quantity may be admitted
to the pan and fired to heat the mixing chamber so as to vaporize the hydrocarbon
in said chamber, substantially as specified.
3. The combination in a hydrocarbon burner of the truncated conical chamber F,
the mixing chamber E projected a distance into said chamber, a pipe A leading
from a hydrocarbon supply to the vaporizing chamber A', a pipe leading from said
vaporizing chamber to the mixing chamber and valve C whereby the flow of
vaporized bydrocarbon into the mixing chamber may be regulated.
