Improvements in or relating to Bunsen Burners for Petroleum and
other Hydrocarbons.
A communication from GUSTAV BARTHEL, of 27, Kyffhauserstrasse, Dresden, in
the Empire of Germany, Chemist.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to a Bunsen burner for petroleum and other hydrocarbons
and consists in the arrangement of vapour supply and gas-outlet relatively to each
other at a sharp angle, for the purpose of arranging the gas-outlet pipe together
with the outlet orifice, as near as possible to the burner-head, and at the same
time of enabling the pipes to be easily cleaned from the lampblack deposited when
the oil is gasified.
In the accompanying drawing, Fig. 1 illustrates a petroleum Bunsen-burner
according to the present invention in front elevation, partly in section.
Fig. 2 shows the same burner in side elevation, in section.
Fig. 3 is a plan view and
Fig. 4 is a front elevation partly in section of a modified construction, in which
the burner head is cast in one piece with a portion of the pipe.
Fig. 5 shows the last construction in plan.
The burner which may be secured to the oil reservoir by means of the screw a,
consists of a bifurcated double pipe bb communicating with the gasifying
chamber cc arranged at the lower part of the burner head. The petroleum vapours
produced rise in the pipes bb and are completely gasified in the gasifiers cc which
owing to their being arranged close to the flame and to their metallic connection
with the burner head are strongly heated. During this gasifying considerable
quantities of soot are deposited. The gases pass through the pipes dd also in
communication with the gasifying chamber and issue from the central discharge
nozzle or opening e. On their escape from the latter the gases are mixed with
air and pass into a pipe f and into a double wall cap 9 from which they escape
through fine holes m and becoming ignited, form the flame which strikes against
the flange h and is projected upwards by the latter.
The flame striking the flange h makes it red hot, and the heat produced is con-
ducted by the horizontal plate h¹ to the gasifying chambers cc arranged at its lower
side.
To enable the pipes bd to be easily cleaned of the soot deposited in them they
are arranged in such position relatively to each other that their longitudinal
axes (Fig. 3) when continued will not intersect. The gas outlet pipes dd com-
municate with the chamber k (Fig. 2) closed at the bottom by a screw cap 1. When
this cap is removed the burner when unscrewed from the reservoir can be easily
cleaned without special tools by cleaning out by means of a wire etc. the soot
deposit near the gasifiers through the pipes 66 and through the pipes dd.

In the modification shown in Fig. 4 the double pipe dd and a portion of the
pipe bb together with the gasifying chambers is formed in one casting there
being arranged opposite the places where the pipes dd merge into the pipes bb
openings r screw-threaded inside and closed by screw plugs s. The hollow space k in
the centre of the bent tube d d being omitted this tube can be cleaned through the
openings after the screw plugs s have been removed. The double pipe b b is inserted
into the cast portion and soldered or secured in other suitable manner.
casting is also provided with upwardly extending projections or pins o which
project between the cap g and the flange h into the flame and are thus strongly
heated. Owing to the gas-outlet pipe with the outlet orifice and the gasifying
chambers being formed in one casting these parts are strongly heated said heating
being still more increased by the projections or pins so that the strongly heated
gases produce an intensely hot flame.
Having now particularly described and ascertained the nature of this inven-
tion as communicated to me by my foreign correspondent and in what manner
the same is to be performed I declare that what I claim is :-
1. A Bunsen burner for petroleum and other hydrocarbons characterized by the
arrangement of vapour supply pipes bb and gas-outlet pipes dd in the shape of
bifurcated double pipes meeting at a sharp angle for the purpose of placing the
gas outlet pipes together with the outlet opening e near the hottest portion of the
burner the pipes being so arranged relatively to each other that they can be
cleaned by wires entering from their bifurcation points substantially as described.
2. In a burner of the character described the modification consisting in casting
in one piece the gas outlet pipes d d together with a portion of the vapour supply
pipes bb and gasifying chambers cc projections or pins adapted to project into the
flame being provided for the purpose of producing a greater transmission of heat
openings closable by plugs being provided opposite the place in which the gas-
outlet pipes dd join the gas supply pipes bb for the purpose of facilitating the
cleaning of the pipes dd substantially as described.
3. The combination and arrangement of parts constituting the complete Bunsen
burner for petroleum and other hydrocarbons substantially as described and
illustrated in Figures 1 and 2 and 3 or in Figures 4 and 5 of the accompanying
drawings.
