COMPLETE SPECIFICATION.
An Improved Nozzle adapted for Burning Oils or Spirits so as to
Improve or Increase Combustion in Steam Boiler or other
Furnaces.
We HENRY JOSEPH BARRETT of 17 High Street Kingston upon Hull, in the
County of York, Commission Merchaut, and HECTOR FOSTER FOURNY, also of
19 Spring Street Kingston upon Hull, Consulting Engineer & Marine Surveyor
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 :-
.
The object of this invention is the arrangement of a nozzle, which shall
discharge, inject or introduce a combination of steam, oil or spirit & air, into steam
boiler or other furnaces, so as to increase or improve the combustion in the said
furnaces.
The air may be introduced at atmospheric pressure & temperature, or at a higher
pressure & temperature by mechanical means. The oil or spirit may be delivered
to the nozzle by gravity, or under pressure by means of hydraulic, steam, compressed
air or other cylinders or appliances.
The nozzle may be used either in conjunction with a coal fire, or alone, as a
means of combustion, and is applicable to all kinds of furnaces.
The nozzle consists of an outer and inner tube. At the end of and on the
circumference of the outer tube are branches, fitted with cocks or valves for
regulating the steam & oil or spirit supply.
Two or more branches can be fitted as may be found suitable for mixing or using
different kinds of oil or spirit, at one and the same time.
The inner tube is for the air supply and is fitted with a regulating valve, either
of butterfly or screw down type.
For certain purposes & when the necessary amount of air is ascertained, this
valve may then be dispensed with.
The fore part of the nozzle has perforations of suitable shape, to allow contents
of outer tube to be discharged, and is tapered so as to cross and spread the steam
& oil or spirit as it leaves the nozzle, & thus intimately mix with the air delivered
by the inner tube, so that the whole of the elements required to be used, may enter
into complete combustion.
This fore part of the nozzle being inserted through the furnace front into the
furnace, the cocks or valves remain outside for regulating the supply to the
nozzle.
In order that our invention may be fully understood and readily carried into
effect, we will describe it more particularly by the aid of the accompanying
drawings, in which is represented a nozzle constructed in the manner above
referred to.

page_text: Arrows indicate the direction of the flow of the air, steam & oil or spirit to th
fore part of the nozzle, which is tapered to cause the whole of the above fluids &
gases to mix intimately at the mouth or outlet of the nozzle, where introduced into
the furnace.
Fig. 2. represents an end elevation at the outlet end of nozzle, shewing two kinds
of perforation H and H¹.
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 we do
not claim any of the parts of the nozzle separately, or otherwise than as working in
combination for the purpose or purposes described, but we declare that what we
claim is :-
:-
The arrangement & combination of the whole of the parts constituting the
improved nozzle adapted for burning oils or spirits, so as to improve or increase
combustion by a combination of fuel in steam boiler or other furnaces, in the
manner & by the means, substantially as described.
