The present invention relates to a new arrange
ment or apparatus for separating and removing
dust from the ?ue gases being discharged through
chimneys. The principal object of the invention
is to provide a concentrator for intensifying a
2
circumference of the chimney and be caused to
be drawn upwardly through the latter with the
smoke and gases arising through the chimney.
This intensi?ed dust ?lm will escape through the
annular opening 5 into the channelway 8 where
it will ‘be drawn within the dust collector NJ. The
dust ?lm will be caused to circulate within the
dust ?lm along the inner, walls of a chimney which
when used in combination with a dust collector
will more efficiently separatethe dust or heavier

the pipe I3 into the chimney. From this arrange

contained within the gas ?lm will be thoroughly
separated therefrom and be prevented from ex
