Improvements in or relating to Apparatus for Use in Burning
Liquid Fuel.
I, CHARLES WEYGANG, of 17, Park Place, Gravesend, in the County of Kent,
Chemist, 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 the formation of liquid-fuel spray and the delivery of such
spray with or without water spray mixed therewith, into the furnace wherein it is
to be consumed, and it will be best understood by reference to the accompanying
drawing which is a diagrammatic section of a convenient form of the improved
apparatus for obtaining the desired results.
In carrying out any invention as illustrated in the drawing I provide a receptacle a
for containing the liquid fuel, particularly mineral oil, which may be supplied to it
from any suitable reservoir through a pipe b. This pipe is fitted with a valve or
cock which may be adjusted to suit the rate at which the liquid-fuel is required
to flow into the receptacle a, or to completely stop such flow.
The delivery end of the pipe b is provided with a ball valve c c¹ the ball c of
which is buoyant and floats on the surface of the liquid fuel, so that the said ball
may be moved up to the valve seating c¹ to automatically shut off the supply
of the liquid fuel after a sufficient quantity of the latter bas flowed into the
receptacle a. When the level of the liquid in the receptacle a descends owing to
the withdrawal of the said liquid the ball c leaves the seating c¹ as shown in the
drawing, and allows fresh liquid to enter.
The receptacle is surrounded by a vessel d adapted to contain water for
keeping the liquid-fuel cool, the water being circulated through the vessel d by any
convenient means not shown in the drawing.
e is a bent pipe open at both ends, the lower end being at or near the bottom of
the receptacle a and the other end projecting outwards from the said receptacle and
leading into the furnace; fis a blast pipe whose discharging end terminates just
over the discharging end of the tube e and which is provided with a jet f¹ for
delivering steam or compressed air. g is a pipe connected to the blast pipe fat a
point behind the discharging end of the jet f and leading down to near the bottom
of the vessel d.
The pipes ef and g are provided with cocks, or valves, not shown in the drawing
for enabling any one or more of them to be more or less closed or rendered
inoperative according to force required and to the nature of the spray it is desired
to supply to the furnace.
When a current of air, or steam, is forced through the blast pipe f it passes
across the upper end of the pipe e and causes the liquids to be drawn up through
the pipes e and g from the respective vessels a and d in proportion to the force of
the draught through the blast pipe f, and as these liquids issue from the end of the
ends of the pipes and e, they are pulverized and shot forward in a very fine
spray into the furnace.

page_text: The liquid fuel may thus be regulated by the force of the draught in the blast
pipe and further by the cocks or valves above referred to.
The water drawn through the pipe g is supplied for the purpose of assisting the
combustion of excess of carbon, and thereby economizing the consumption of the
liquid fuel and more or less preventing smoke.
I do not limit myself to the precise form of apparatus shown in the drawing
as the same may be varied without departing from the essential features of the
invention.
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 improved apparatus for use in burning liquid fuel with or without water
combined therewith substantially as hereinbefore described with reference to the
accompanying drawings.
(2) An apparatus for the purpose of spraying liquid fuel in which the latter is
automatically drawn to the lip of the nozzle by a partial vacuum produced by means
of a current of air, or steam, passing over the lip of the nozzle where it is pulverized
as it issues.
(3) The mixing of water with liquid fuel substantially in the manner herein before
described.
