Certain Improvements in connection with Steam Boilers and other
Furnaces for Preventing the Smoke Arising from same.
I, SAMUEL PICKARD of Union Row Grove Lane Handsworth in the County
of Stafford Agent, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a new or improved method for improving combustion
of coal and other substances in furnaces more particularly those of steam boilers.
either stationary or otherwise and the improvements consist in an arrangement for
conveying air through pipes so constructed as to be laid in the flue or flues conveying
the waste heat from the furnace to the chimney by which means the air passing
through is raised to the temperature of the furnace before it is emitted. These
pipes which have communication with the outside to draw a constant supply of air
terminate inside the boiler at a given distance behind the furnace bridge where the
said pipes enter a specially constructed chamber fitted inside with a self acting fan
having suitable apertures. The fan causes the air to be broken up and distributed
through these apertures in currents and so combine with the gases or smoke which
on thus receiving fresh oxygen burst into flame.
Thus the smoke and gases arising from the furnace will be entirely consumed.

Certain Improvements in connection with Steam Boilers and other
Furnaces for Preventing the Smoke Arising from same.
I, SAMUEL PICKARD of Union Row Grove Lane Handsworth in the County
of Stafford Agent, 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, reference being had to the drawing, accompanying
this spécification:-
My invention relates to a new or improved method for improving combustion of
coal and other substances in furnaces more particularly those of steam boilers
either stationary or otherwise and the improvements consist in an arrangement for
conveying air through pipes A. so constructed as to be laid in the flue or flues B.
conveying the waste heat from the furnace C. to the chimney by which means the
air is raised to the temperature of the furnace before it is emitted. These pipes A.
which have communication with the outside air to draw a constant supply therein,
terminate inside the boiler at a given distance behind the furnace bridge E. where

page_text: the said pipes enter a specially constructed chamber F. provided with suitable
apertures and fitted inside with a self acting fan G.
The position of the chamber F. where the oxygen is emitted at the same degree
of temperature as the furnace being located as stated at a given distance behind
the bridge wall E the intervening space H forms a combustion chamber where the
unconsumed gases upon coming into contact with the fresh supply of oxygen
-combine and burst into flame.
The aforesaid fan G. has the effect of causing the air to be broken up and
distributed through the apertures in the chamber in currents which causes a
thorough combination with the gases or smoke and which thus amalgamating with
the oxygen are consumed as stated.
The air pipes A. are of special construction tapering from the outside to the
diffusing chamber F. In connection with the air pipes A a steam pipe I may be
arranged therein said steam pipe being suitably placed in connection with the
fan G as an auxiliary means for working said fan and may also be used for
the purpose of creating a forced draught when required.
By my improvements no cutting or drilling of holes in boiler is required. Does
not interfere with existing arrangements and is entirely self acting, economises fuel,
and improves draught.
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.
Firstly. In connection with steam boilers and other furnaces the improved
means for preventing the smoke arising from same, substantially as herein described
and illustrated.
Secondly. In connection with the means for preventing the smoke arising from
steam boilers and other furnaces the construction and arrangement of tapering air
pipe or pipes such as A and steam pipe I in connection with the specially
constructed chamber F substantially as herein described and illustrated.
Thirdly. In combination with steam boilers and other furnaces the construction
and arrangement of tapering air pipe or pipes A. in the flue or flues B. said air pipe
or pipes terminating in the chamber F said chamber being provided with suitable
apertures, and with a fan G as set forth.
Fourthly. In combination with the hereinbefore described arrangements of parts
in connection with steam boilers and other furnaces the specially constructed air
chamber F. located behind the bridge wall E the combustion chamber H formed
by the intervening space between said air chamber F and said bridge wall E
substantially as described and illustrated.
