Improvements relating to Means for Promoting the Consumption of
Smoke and for Suppressing Combustion in Steam-boiler Tubes
and other Flues.
I, Dr. RICHARD SICKEL, of Nörten, in the Empire of Germany do hereby declare
the nature of this invention to be as follows:-
This invention relates to means for promoting the consumption of smoke in steam-
boiler tubes and other flues.
By arranging one or more apparatus constructed according to the said invention
within the flame tubes of steam boilers, or at other suitable points within the flue of
fire-places of any kind, the troublesome and disadvantageous smoking in chimneys can
be obviated.
The improved apparatus employed for this purpose comprises a hollow body the
shape of which is somewhat similar to that of a sugar cone, the point of this body
being turned in the direction in which the gases of combustion pass. In the open
rear end of the said hollow body terminate one or more admission pipes which are
connected by a ring with the hollow body.
This body or the connecting ring, or both the body and ring, are provided with
small holes which enable the air introduced into the body to be discharged into the
gases of combustion and to be intimately mixed therewith.
This mixing is materially promoted by placing upon the aforesaid hollow body one
or more helices which cause the gases of combustion to pass through the flue in a
helical line.
The oxygen contained in the air admitted is designed to cause the combustion of the
unburnt particles of the fuel carried away by the gasos and to convert into carbonic
acid the carbonic oxide contained in the gases when the combustion is imperfect.
The said hollow body compels the gases of combustion to pass through an annular
passage, increases by the contraction of the free area of the flue the velocity of the
gases of combustion so much that the soot therein will be carried away through the
flues, and oxygen is introduced through the small holes in the hollow body for
the purpose of burning the solid particles contained in the gases of combustion which
have not been completely oxidized.
The said helices increase the length of the passage for the gases of combustion
within the flue, thus affording a better opportunity for giving off the heat generated
to the substance to be heated and cause the particles of carbon and soot, and the
carbonic acid of the gases of combustion, to be mixed with the air introduced into
the flue through the perforations and promote in this manner the consumption of
smoke and the production of fresh heat arising from combustion.
Other gases, vapours or liquids can be introduced with or without atmospheric air
into the flue by means of the described apparatus either for the purpose of consuming
smoke, generating fresh heat, or rapidly suppressing the process of combustion within
the flue.
The end of the admission pipe or pipes which is not connected with the said hollow
body terminates outside the flue in the open air, or in receptacles of pumping
apparatus arranged outside the fire place if gases vapours or liquids are introduced
into the apparatus.
For regulating the quantity of the gases vapours or liquids to be introduced, the
admission pipe or pipes can be provided with flap slide or other suitable valves

combined.

COMPLETE SPECIFICATION.
Improvements relating to Means for Promoting the Consumption of
Smoke and for Suppressing Combustion in Steam Boiler Tubes
and other Flues.
I, Dr. RICHARD SICKEL, of Nörten; in the Empire of Germany, Director of Sugar
Works, do hereby declare the nature of this invention and in what manner the saine
is to be performed, to be particularly described and ascertained in and by the
following statement:-
This invention relates to ineans for promoting the consumption of smoke in steam-
boiler tubes and other flues.
By arranging one or more apparatus constructed according to the said invention
within the flame tubes or flues of steam boilers, or at other suitable points within the
flue of fire-places of any kind, the troublesome and disadvantageous smoking in
chimneys can be obviated.
The improved apparatus is represented in the accompanying drawing the figures of
which are hereinafter referred to.
The said apparatus comprises a hollow body' K, K the shape of which is somewhat
similar to that of a sugar cone, the point of this body being turned in the.direction in
which the gases of combustion pass. In the open rear end of the said hollow
body KK terminate one or more admission pipes which are connected by a
ring cc Figure 1 with the hollow. body.
This body or the connecting ring cc or both the body and ring are provided with
small holes a a which enable the air introduced into the body to be discharged into
the gases of combustion and to be intimately mixed therewith.
This mixing is materially promoted by placing upon the aforesaid hollow body one
or more helices Z Z which cause the gases of combustion to pass through the flue in a
helical line.
The oxygen contained in the air admitted is designed to cause the combustion of
the unburnt particles of the fuel carried away by the gases and to convert into
carbonic acid the carbonic oxide, contained in the gases when the combustion is
imperfect.
The action of the apparatus represented in the drawing is as follows.
. The said hollow body KK compels the gases of combustion to pass through an
annular passage and increases by the contraction of the free.area of the flue the
velocity of the gases of combustion so much that the soot therein will be carried
away through the flues, and oxygen is at the same time.introduced through the small
holes a a in the hollow body for the purpose of burning the solid particles contained
in the gases of combustion which have not been completely. oxidized.
"The said helices Z Z increase the length of the passage for the gases of combustion
within the flue thus affording a better opportunity for.giving off the heat generated to
the substance to be heated, and cause the particles of carbon and soot, and the carbonic
acid of the gases of combustion, to be. mixed with the air introduced into the flue
through the perforations a a and promote in this manner the consumption of smoke
and the production of fresh heat arising from combustion.
Other gases, vapours or liquids can be. introduced with or without atmospheric air
into the flue by means of the described apparatus, either for the purpose of consuming
smoke, generating fresh beat, or rapidly suppressing the process of combustion within
the flue.

page_text: The end of the admission pipe or pipes which is not connected with the said hollow
body terminates outside the flue in the open air, or in receptacles of pumping apparatus
arranged outside the fire place; if gases vapours or liquids are introduced into the
apparatus.
For regulating the quantity of the gases, vapours or liquids to be introduced, the
admission pipe or pipes can be provided with flap slide or other suitable valves.
The whole apparatus can be made of metal or of earthen or clayish substance or all
combined.
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
The combination of the means for the introduction of gases, vapours or liquids with
the devices arranged in the flues of steam boilers and fireplaces of any kind, as and
for the purpose described.
