PROVISIONAL SPECIFICATION.
Liquid Fuel Burning Apparatus.
HENRY LANCELEY and RICHARD HANKINSON LANCELEY, both of Providence
Foundry and Engine Works, Brook Street, Chester, do hereby declare the nature
of this invention to be as follows:-
This invention relates to that description of apparatus used for burning liquid
fuels in connection with steam boilers, and various other industrial purposes.
The object of the invention is to so construct the apparatus that when the liquid
fuels are introduced into the furnaces, they i.e. the fuels-shall be completely
broken up, pulverized, or atomized; and being ignited form a mass of flame of
intense heat.
The arrangements proposed are as follows:-The fuel is contained in a
tank or receptacle placed above the level of the boiler or other furnace, and
being conveyed in suitable pipes, falls by its own weight into the furnace.
Immediately before, and on emerging from the pipes conveying it into the
furnace (the peculiar arrangement & construction of which pipes are the object of
this invention) the liquid fuel is at once brought into contact with steam jets
issuing from orifices placed in such relative positions to the liquid fuel as to
completely break it (i.e. the fuel) up, atomize or pulverize it; and being ignited it
forms into a mass of flame of intense heat.
The pipe conveying the liquid fuel from the tank or other receptacle is connected
immediately outside the furnace with a steam pipe, which steam pipe completely
encircles or encloses it, up to or near to the point at which it discharges the fuel into
the furnace.
At a point in the fuel pipe near to the outlet, an orifice is made so as to
communicate with, and admit steam from the pipe encircling it; and an orifice is
also made at the end of the steam pipe.
The orifices are placed is such positions as to bring the steam jets in contact with,
and break up the fuel in the manner before described.
An annular ring may also be placed near to the end, and completely encircle
both the oil and steam pipes in such a manner as to further the complete combustion
of the fuels.

COMPLETE SPECIFICATION.
Liquid Fuel Burning Apparatus.
HENRY LANCELEY and RICHARD HANKINSON LANCELEY, both of Providence
Foundry and Engine Works, Brook Street, Chester, Engineers, 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 that description of apparatus used for burning liquid
fuels in connection with steam boilers, and various other industrial purposes.
The object of the invention is to so construct the apparatus that, when the liquid
fuels are introduced into the furnaces, they-i.e. the fuels-shall be completely
broken up, pulverized or atomized, and being ignited, form a mass of flame of
intense heat.

page_text: The arrangements proposed are as follows:-The fuel is contained in a tank
or receptacle placed above the level of the boiler or other furnace, and being
conveyed in suitable pipes falls by its own weight into the furnace. Immediately
before and on emerging from the pipes conveying it into the furnace (the peculiar
arrangement & construction of which pipes are the object of this invention) the
liquid fuel is at once brought into contact with steam jets issuing from orifices
placed in such relative positions to the liquid fuel as to completely break it (i.e. the
fuel) up, atomize or pulverize it; and being ignited it forms into a mass of flame of
intense heat.
The pipe conveying the liquid fuel from the tank or other receptacle is connected
immediately outside the furnace with a steam pipe, which steam pipe completely
encircles or encloses it, up to, or near to the point at which it discharges the fuel
into the furnace. At a point in the fuel pipe near to the outlet, an orifice is made
so as to communicate with, and admit steam from the pipe encircling it, and an
orifice is also made at the end of the steam pipe. The orifices are placed in such
positions as to bring the steam jets in contact with, and break up the fuel in the
manner before described.
An annular ring composed of fire clay or other suitable material may also be
placed near to the end of the burner pipes in the furnace, and completely encircle
both the oil & steam pipes, in such a manner as to further the complete combustion
of the fuels.
Referring to the drawings herewith the working of the apparatus may be described
as follows:-
Steam is conveyed by suitable pipes to either one or both of the inlets or branches
marked A. on Fig. 1; and oil is similarly conveyed to one or both of the inlets or
branches marked B. The oil passes along the pipe C and on passing the steam jet
issuing from the steam pipe Ď by means of the orifice E in the said oil pipe is
partially broken up or atomized; complete breaking up being accomplished by the
jet of steam issuing from the steam pipe D through the orifice F in the closed end
of the said steam pipe D.
The jet of steam issuing from the orifice F also serves to carry forward the
atomized oil, which coming in contact with the heating furnace-or heated annular
ring, dash plate, or small fire kept for the purpose of igniting the fuel-is at once
ignited & forms into flame of intense heat.
The pipe for conveying the steam to the desired points of contact with the oil or
liquid fuel is completely closed at the end, except for allowing the fuel pipe to pass
through & also for the orifice for steam jet F. These burner pipes-i.e. the internal
oil, or, liquid fuel pipe, and the external or steam pipe are shewn on the drawings
as circular in section, but they may be made any regular or irregular shape or
section; and the section of the orifice for the inlets of steam jets to break up and
carry forward the oils may also be of any regular or irregular shape. Further, the
oil pipe may either be finished off level with the outer end of the closed steam pipe
or be somewhat carried forward and a lip formed on end of same as at G in Fig. 2,
for the better distribution of the partially broken up, or atomized oil or fuel. The
orifice in the end of the closed steam pipe may be placed either immediately in
contact with the internal oil pipe as shewn at F in Figs. 1, 3 & 6, or at a slight
distance from it as shewn at F in Figs. 2 & 4. The two plugs shewn in the
branches A & B in Fig. 1, are supplied so as to block up either one of the
corresponding branches when both are not used. By removing the plug H in
Fig. 1. any sediment that may have got into the oil pipe C may be readily
removed.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1st. The method of applying the steam jets for the purpose of breaking up,
atomizing an not

page_text: 2nd. The method of applying the central oil, or liquid fuel pipe, with the orifice
near discharge end of same, and also with the projecting lip.
3rd. The method of applying the closed annular steam pipe with the orifice at
end of same for the complete breaking up & carrying forward of the liquid fuel.
4th. The method of combining the annular steam pipe, internal oil pipe and
casting, forging, or combination & arrangement of pipe fittings, into which the said
oil & steam pipes are fitted & secured; and which casting, forging or combination
and arrangement of pipe fittings, is provided with the steam and oil inlets as herein
described.
