PROVISIONAL SPECIFICATION.
Improvements in Apparatus for the Treatment of Noxious Gases.
I, FREDERICK WILLIAM LACEY of West House Portarlington Road Bourne-
mouth Hants Civil Engineer do hereby declare the nature of this invention to be
as follows:-
Where furnaces or destructors have been employed for dealing with towns
refuse, considerable difficulty has been experienced in dealing with the gases
passing into the atmosphere, which are at times offensive.
The object of my invention is to render these offensive gases odourless and thus
prevent a cause for complaint.
My improvements relate to an apparatus constructed of firebrick or other suitable
material, having openings to admit the flame of oil jets or other liquid fuel, so that
the flame of the jets may mingle with the products of combustion, produced in
burning towns refuse and so burn up the flamable and noxious gases. The sides
and internal parts of the apparatus also assist by the intense heat generated, and
retained to some extent on the surfaces.
In the flue leading from refuse furnaces, I arrange a combustion chamber of
sufficient capacity to take the products of combustion from the burning refuse and
also the products of combustion from the liquid fuel jets.
The top of the combustion chamber is arched similar to an ordinary furnace,
baffle walls are provided in the centre and projecting from the sides of the
chamber, to cause the products of combustion to waive in passing through; pro-
vision is made for feeding with a little coal or other fuel, which is sometimes
necessary in starting, or when the liquid fuel is thick and liable to stick in the
nozzle of the jets.
The liquid fuel jets may be of any known kind, such as used for creosote oil or
tar, having attachments for the reception of oil, tar or other liquid fuel and also
nozzles to allow the fuel to pass with nozzles for the supply of steam or compressed
air; in order to create the flame nozzles may be used similar to those known, and
used with the Lucigen or Well's lights.
At the back of each nozzle cocks are provided to regulate the supply of
liquid fuel, the fuel is retained in volume in troughs or tanks over the jets,
the fuel is made hot when desired by the heat from the combustion chamber or by
steam pipes.
Doors are provided to examine the inside of the chamber and clean out dust.
At the end of the combustion chamber nearest the chimney, a steam boiler may
be fixed in or over the flue to provide steam for the jets and engine power to drive
air compressors or other machinery.

COMPLETE SPECIFICATION.
Improvements in Apparatus for the Treatment of Noxious Gases.
I, FREDERICK WILLIAM LACEY, West House, Portarlington Road, Bourne-
mouth, in the County of Hampshire, Civil Engineer, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement :-
My invention relates to an improved apparatus for the treatment of the products
of combustion from refuse furnaces or analogous appliances.

page_text: I will now describe the nature of my invention, by the aid of the accompanying
drawings, which more clearly elucidate the character of my invention. But before
referring to the drawings I wish it to be distinctly understood that I do not desire
to be confined to the employment of the exact details shown, as these may be
modified without departing from the nature of my said invention.
Figs. 1, 2 and 3 represent respectively a longitudinal elevation, a plan partly in
section, and a cross section of my invention, and the same letters denote similar
parts in each figure.
a,
is the end where gases enter from refuse furnaces; b, the body part or com-
bustion chamber, where the gases are acted upon by the heat and flame produced
by oil jets; c, c', c³, c³, c¹ and care baffle walls, projecting from the sides of the
chamber, which cause the products of combustion to waive in passing through;
d, are baffle walls in the centre, having angle sides to reflect the flame and heat,
and cause the products of combustion to waive in their course towards the chimney
shaft; e and eare oil troughs passing over the oil jet apparatus to allow a con-
tinuous supply; f, oil pipes passing from the oil troughs to the oil nozzles ;
9, steam or compressed air pipes to supply the nozzles; h, h', h³, h³, h*, and h³, are
the jet nozzles which produce the spray of oil and steam, or air, and create flame;
j, iron door to examine the nozzles, and provide means of placing fuel on the fire
grate k; l, are strengthening girders to support the brickwork; m, is the main
brickwork supporting the firebrick n; inside the chamber.
The products of combustion from refuse furnaces enter at a, and are first
baffled on the projecting walls c, and e¹; in passing a little further through the
chamber they are met with the heat and flame from the nozzles h, h', h and h³,
and again baffled on d, and on and c³, afterwards acted upon by the heat and
Hame of more jets, and further mixed and baffled before passing out of the
chamber thus the products of combustion are compelled to pass through intense
heat and flame, and the offensive and inflammable gases are subjected to such
treatment that will purify them before passing into the atmosphere.
The heat may be regulated by the supply of oil, steam, or air, and at times
some of the oil jets may be shut off, or even more jets employed than shown on
my drawings, as much depends upon the quality of the refuse burnt in the refuse
furnaces.
The heat produced by these oil jets and refuse furnaces may be utilized to
generate steam in steam boilers fixed beyond the apparatus.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same may be performed, I declare that what I claim
is included in the following:
First. The arrangement of oil jets to pass their flame into a firebrick chamber,
where the products of combustion from refuse furnaces are passing, substantially,
and for the purpose described.
Second. Apparatus consisting of firebrick with baffle walls, and oil jet arrange-
ments, substantially, and for the purpose described.
Dated this 29th day of December 1892.
