PROVISIONAL
SPECIFICATION.
A Method of Destroying Smoke, and Apparatus for that Purpose.
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
to be as follows:-
My invention relates to means of destroying the smoke which issues from chimneys
of houses, factories or other establishments, which I effect in the following manner.
By means of a jet or jets of steam at moderate pressure, arranged to act as ejectors,
I cause the smoke to pass in a current along with the steam over an extended
surface of water, and preferably through a shower or spray, by which the solid
matters, sulphurous and other impurities suspended in the smoke are entrapped, and
retained in the water while the colorless gases pass away. In order more com-
pletely to mix the smoke with the steam, may cause the mixed current to pass
through a Barker's mill causing it to revolve, and this by means of blades striking
the water may cause the required spray. In order to reduce deposit of soot in the
flues leading to the ejectors, I preferably, near each fire place, provide a vessel
partly filled with water and cause the smoke to pass into this vessel in a current
directed on the water, in which much of the soot becomes deposited, the smoke
then passing along the flues to the ejectors.

COMPLETE SPECIFICATION.
A Method of Destroying Smoke, and Apparatus for that Purpose.
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:-
My invention relates to means of destroying the smoke which issues from chimneys
of houses factories or other establishments, which I effect in the following manner.
By means of a jet or jets of steam at moderate pressure arranged to act as ejectors,
I cause the smoke to pass in a current along with the steam over an extended
surface of water and preferably through a shower or spray, by which the solid
matters, sulphurous and other impurities suspended in the smoke are entrapped and
retained in the water, while the colourless gases pass away.
Apparatus for thus treating smoke must necessarily vary in form and dimension
to suit the conditions of the buildings to which they are applied. The accom-
panying drawings illustrate an arrangement applicable to a set of house chimneys
in this case five in number opening side by side. Fig. 1 is a longitudinal vertical
section and Fig. 2 is a transverse section. The five chimneys CC open into a
chamber A which may be made of metal plate as shewn, or of other suitable
structural material.
Between each pair of chimneys a narrow plate P projects into the chamber these
plates acting as checks to prevent the smoke which issues from the chimneys from
turning abruptly towards the outlet B at the end of the chamber. D is a section
chamber having a circular inlet provided with multiple jets J constituting a steam
ejector. The steam issuing from these jets creates a draught drawing the smoke
from the chimneys C and mingles with the smoke in the chamber D. From this

page_text: chamber, the mixture of smoke and steam passes into a third chamber E around
and between a number of tubes open at both ends so that wind can pass through
them keeping them cool. By these cool tubes the steam is more or less condensed,
and the smoke mixture which may still contain a proportion of uncondensed steam
passes finally through a fourth chamber F around and between a number of tubes
through which water passes. This water is admitted by a pipe W to form a layer
on the cover plate G of the chamber whence it descends at the one side to pass
through the tubes in F and flows away by a pipe X. I prefer to provide in the
plate G perforations through which a portion of the water can descend trickling on
the tubes in F. This water, and such additional water as results from the conden-
sation of the steam descends through the chambers E, D and A and finally passes
away by a pipe H entrapping and carrying with it the solid impurities of the smoke
while the colourless gases pass away by the outlet O at the top of the apparatus.
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
1. The herein described method of destroying smoke by mixing it with steam
and cooling the mixture so as to condense the steam and thus entrap the impurities
suspended in the smoke.
2. In apparatus for destroying smoke, the combination of a chimney or set of
chimneys with a steam ejector, a chamber for mixing the smoke and steam, and
chambers provided with tubes or equivalent surfaces for cooling the mixture and
condensing the steam, substantially as described.
