PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Burning Liquid Fuel in Furnaces.
I, COLIN MACCULLOCH SHARP, Brass Finisher, Ladyburn, Greenock,
Renfrewshire, do hereby declare the nature of this Invention to be as follows:-
This Invention has for its object to provide simple and inexpensive apparatus
of improved construction for burning liquid hydrocarbons in steam boiler or other
furnaces.
The improved apparatus comprises a vaporiser which may be conveniently made
of iron or steel of cylindrical or other form and having an inlet for water or steam
under pressure and an outlet for the steam generated or superheated within it.
The inlet is connected by a pipe provided with a regulating valve led from a
water tank having a head of water, means being provided for stopping the water
supply and for admitting live steam instead when desired.
The outlet is formed by a tube extending upwards within the vaporiser to such
an extent as to ensure the discharge of steam only, and the outlet is connected to
a pipe outside terminating in a jet nozzle directed towards the vaporiser. The
nozzle contains an oil chamber to which oil is led from a suitable tank or vessel,
the steam iet being preferably directed through the oil chamber, and the supply
of both steam and oil being regulated by means of valves. The combined steam
and oil nozzle may however he of any of the types used in connection with spray
lamps or burners.
In the operation of the apparatus water is led into the vaporiser which in
starting is heated for a short time by a flame arising from oil burned in an open
cup attached to the lower side of the vaporiser. The steam generated in the
vaporiser passes to the spray nozzle from which on the oil being ignited a hot
flame, due to the combustion of the oil and decomposition of the steam, is
directed on to the vaporiser, thereby effecting vaporization of the water contained
in it.
When the vaporiser attains a high temperature and steam is generated in the
boiler under which the apparatus is fitted, live steam may he passed through the
vaporiser instead of the water. and the steam within is superheated and in passing
from the spray nozzle is the more readily decomposed.

I, COLIN MACCULLOCH SHARP. Brass Finisher, Ladyburn, Greenock,
Renfrewshire. do hereby declare the nature of this invention and in what manner
[Price 8d.]

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement:
This Invention has for its object to provide simple and inexpensive apparatus of
improved construction for burning liquid hydrocarbons in steam boiler or other
furnaces.
The Invention is illustrated by the accompanying drawings, Figure 1 of which
is a vertical section of the improved apparatus for burning liquid fuel, and
Figure 2 a part view of a boiler shewing the apparatus in position in the furnace.
The improved apparatus comprises a vaporiser A which may be conveniently
made of iron or steel or other metal of cylindrical or other form and having an
inlet B for water or steam under pressure and an outlet C for the steam
generated or superheated within it. The inlet B is connectd by a pipe D provided
with a regulating valve E led from a water tank having a head of water, or from
the town supply or other means whereby the requisite pressure may be obtained,
means being provided for stopping the water supply and for admitting live steam
instead when desired.
The outlet C is formed by a tube extending upwards within the vaporiser A
te such an extent as to ensure the discharge of steam only, and the outlet C is
connected to a pipe F outside terminating in a jet nozzle or nozzles G directed
towards the vaporiser A. The nozzle G contains an oil chamber to which oil is
led by a pipe K from a suitable tank or vessel L, the steam jet being preferably
directed through the oil chamber, and the supply of both steam and oil being
regulated by means of valves. The combined steam and oil nozzle may however
he of any of the types used in connection with liquid fuel burning.
In the operation of the apparatus water is led into the vaporiser A which in
starting is heated for a short time by a flame arising from oil burned in an open
cup H attached to the lower side of the vaporiser A, or a fire may be kindled on
the fire bars I of the boiler J for this purpose. The steam generated in the
vaporiser passes to the spray nozzle G by way of the outlet C and pipe F from
which on the oil being ignited a hot flame, due to the combustion of the oil and
decomposition of the steam, is directed on to the vaporiser A, thereby effecting
vaporization of the water contained in it.
When the vaporiser A. attains a high temperature and steam is generated in the
boiler J under which the apparatus is fitted, live steam may be passed through
the vaporiser instead of the water, and the steam within is superheated and in
passing from the spray nozzle G is the more readily decomposed.
Having now particularly described and ascertained, the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is :-
Apparatus for burning liquid fuel in furnaces consisting of a vaporizer having
an inlet connected to a water tank or other supply and an outlet for the vapour
generated in the vaporizer terminating in a jet nozzle or nozzles having a chamber
connected to an oil tank, said nozzle or nozzles being arranged to direct, the flame
against the vaporizer, substantially as described.
