Improvements in Smoke Consuming Furnaces.
I, PORFIRI ANTONOVITCH ARCHIPENKO, Mechanic, of Kiew, in the Empire of
Russia, 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 :-
The annexed drawings show a form of construction of the smoke consuming furnace.
applied to a Cornish boiler.
Fig. 1 shows a longitudinal section on line X X X of Fig. 2.
Fig. 2 is a cross section on line yy of Fig. 1.
Fig. 3 is a plan on line Z Z the boiler being removed, whilst, Fig. 4 shows a cross-
section on line W W.
Figs. 5 and 6 are detail views.
From the grate A which is arranged in the usual manner in the flame tube B the
combustion products pass through the latter and into the smoke chamber C lying
behind the back boiler end and to which smoke chamber the smoke tube D is connected
on the upper part. The latter tube runs horizontally over the top of the boiler
masonry and ends in the funnel like enlarged tube E which is shown in Figs. 5 and 6
on a larger scale. This funnel provided on the inner side with helical ribs F; upon
its mouth is rivetted a circular plate G provided with radial slots f, through the middle
of which plate passes the end of the tube D fixed therein by an angle flange.
Over this plate & is placed a plate G 1 provided with corresponding slots fl and kept.
by lateral flanges on plate G and guided by superposed rings f2, 3. According to
the turning of the plate G 1 which can be turned by the handle g and fixed in any
position by screw g 1, the slots f f1 can be brought in more or less coincidence that
is to say may be more or less covered and thereby more or less air can be introduced'
into the tube and by the helical ribs on the inner face of the funnel mixed
thoroughly with the combustion products. The latter pass from tube F into the second.
funnel H which is constructed like the first F and from the latter into the tube I
passing laterally under the boiler. The latter tube ends in a masonry shaft K which
is closed below by a slide L and above by a grate M; upon this grate is lighted a
fire of a material which gives a bright glow without smoke, for instance, coke,
wood, charcoal or the like, before the fire is lighted on the main grate A. The fire-
door N is provided for feeding the grate M. Above the grate the four walls of the-
shaft K continue until they touch the boiler walls, and the front of these four walls.
opens into the flue O.
The products coming from the tube I pass the grate M and the fire thereon, where
the combustible products are consumed, while the incombustible solids are kept back
mechanically, the now remaining oxydized smoke gases leave through the flue O and
turn when arrived at the front, into the channel O 1, pass from there into the flue 02.
and from there to flue 03 and arrived at the end of the latter escape into
the flue P conducting to the chimney.
Under the slide L as well as laterally of the same is a space for removing the
ashes after the slide is pulled out.
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

and provided on the larger ends with annular regulating slides which tube lies outside
the masonry of the furnace and ends under an auxiliary grate M provided in the
furnace casing from which grate M pass flues which lead finally to the chimney.
