An Improvement in Apparatus for Destroying Smoke.

County of London, Retired Military Officer, do hereby declare the nature of this.
invention to be as follows:-
In my Specification No. 5908 of 1891 I described means of destroying smoke by
mixing it with steam and afterwards cooling the mixture by a water shower so as
to condense the steam and precipitate the carbonaceous, sulphurous and other
impurities which form ingredients of smoke.
My present invention relates to a modification of the apparatus whereby I render
the process conveniently applicable for domestic fires, kitchen ranges and the like,
where steam is not available, but where there is water under a certain pressure.
For this purpose, I arrange behind the fire a vertical tube open at the top and
the bottom and so situated that smoke and hot products of combustion pass up it.
In this tube I provide a finely perforated nozzle connected to the water service,
with a suitable cock or valve, in the connecting pipe, so that when the cock or valve
is opened, water issues in a fine spray from the nozzle, ascending the tube along
with the smoke and products of combustion and becoming converted into steam
which mingles with them. In the case of a kitchen range, prefer to supply the
nozzle with hot water from the boiler of the range.
The mixture of steam smoke and products of combustion issuing from the
chimney, or from a number of chimney's connected together, are directed down a
descending flue or channel along with a water shower.

COMPLETE SPECIFICATION.
An Improvement in Apparatus for Destroying Smoke.
I, EDWARD EUGENE DULIER, of No. 27 Sloane Gardens, Chelsea, in the
County of London, 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 :-
In my Specification No. 5908 of 1891 I described means of destroying smoke by
mixing it with steam and afterwards cooling the mixture by a water shower so as
to condense the steam and precipitate the carbonaceous, sulphurous and other
impurities which form ingredients of smoke. My present invention relates to a
modification of the apparatus whereby I render the process conveniently applicable
for domestic fires, kitchen ranges and the like, where steam is not available,
but where there is water under a certain pressure. For this purpose, I provide
apparatus which I shall describe referring to the accompanying drawing shewing a
section of a kitchen range. Behind the fire F I place an open tube T so situated
that smoke and hot products of combustion pass through it on their way to the
chimney C. In this tube I provide a finely perforated nozzle N connected to the
water service, with a suitable cock or valve in the connecting pipe, so that when
the cock or valve is opened, water issues in a fine spray from the nozzle,
passing along the tube T with the smoke and products of combustion and becoming

having a closed boiler under certain pressure I prefer to supply the nozzle N with
hot water from the boiler.
The mixture of steam smoke and products of combustion issuing from the chimney,
or from a number of chimneys connected together, is directed down a descending flue
or channel along with a water shower as described in my previous. Specification
above referred to. A dish D with drain pipe P is by preference placed in front of
the tube T to catch such water_as may issue from the nozzle N without being
converted into steam. The tube T, instead of being horizontal as shewn, might be
placed vertically in the flue, or at an inclination to suit the particular construction
of the fire place to which the apparatus is applied.
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 :-
In apparatus for destroying smoke by mingling steam with it and condensing,
the combination with a fire place or kitchen range of a tube and water spray
nozzle arranged and operating substantially as described.
