I, EDWARD EUGENE DULIER, of Manor House, Mildenhall, in the County of
Suffolk, Retired Military Officer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to apparatus for clearing smoke of its sooty and sulphurous
ingredients.
For this purpose, I mount centrally in an expanded cylindrical part of the
chimney a double nozzle constructed like a Barker's mill and supply it with water,
the issuing currents of which cause it to revolve. To the nozzle I attach blades,
which, revolving with the nozzle, operate as a fan.
In the chimney, below the expanded part, I introduce a dispersing steam jet, and
over the fan blades I provide a cover plate, which may be stationary or may be.
fixed to the blades and revolve with them; from the annular space around the
lower part of the chimney which projects some distance up into the expanded part
I lead a pipe to a drain.
Above the cover plate I form within the expanded part of the chimney an
internal conical casing which does not extend up to the top of the expanded part,
and from the annular space outside this caeing I lead a pipe to a drain.
The apparatus operates in the following manner.
The ascending smoke mingled with steam from the dispersing jet receives also
water spray from the revolving nozzle and is thoroughly mingled therewith by the
blades of the fan. The water particles take up the sooty and sulphurous ingredients
of the smoke and, being thrown against the wall of the expanded part, descend to
the lower annular space whence they pass to the drain, while the gases, cleared or
nearly so, pass upwards around the edge of the cover plate to the upper part of the
chimney. Some of the lighter particles which may be carried up by the ascending
gases find their way over the upper edge of the conical casing into the upper
annular space whence they pass to the drain.
By
When the chimney is such that the smoke descends I substitute for the
revolving nozzle and fan a stationary distributing nozzle and below it stationary
helical blades on which the current of water dashes becoming distributed in fine
spray and mingled with the smoke, the whole acquiring a rotary motion.
centrifugal force the whirling particles of water mixed with the Booty and
sulphurous ingredients of the smoke are caused to bear close against the interior
surface of the expanded part of the chimney and descend to the annular-space and
pass away by the drain, while the gases mostly cleared from the sooty and
sulphurous matters descend the flue that projects upwards into the enlarged part
of the chimney.

page_text: I, EDWARD EUGENE DULIER, of Manor House, Mildenhall, in the County of
Suffolk, Retired Military Officer, 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 :-
My invention relates to apparatus for clearing smoke of its sooty and sulphurous
ingredients, as I shall describe referring to the accompanying drawing, which is a
vertical section of a smoke flue provided with apparatus according to my
invention.
I bend the flue in S form with an ascending limb A, an enlarged descending limb
B, and another ascending limb C.
In the limb A I provide a nozzle D distributing steam which mingles with
the ascending smoke. At the top of the descending limb B I provide a nozzle E
distributing water which mingles with the descending smoke and steam.
In the enlarged part of B I fix a core F having projecting helical blades G
and under them an upwardly projecting part P perforated at its base.
The mixture of smoke, steam and water being caused to travel in a helical course
between the blades G has its heavier particles driven by centrifugal action against
the wall of the limb B on which the sooty and sulphurous ingredients mixed with
water are deposited.
They descend to the bend H whence they are run off by a pipe K leading to
a drain or other discharge.
The combustion gases cleared from the sooty and sulphurous matters ascend the
limb C.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what
I claim is :-
Apparatus for clearing smoke, comprising a flue having an ascending limb
provided with a steam nozzle, a larger descending limb containing a water nozzle
and helical blades, and an ascending limb with a drain at its base.
