Industrial Chimneys.
Pollution from industrial
chimneys (for example a coal burning
power station)
can be reduced by using electrostatic charge.
As well as the waste gases from
burning
coal (CO2, SO2),
the chimney contains many small
particles of unburnt fuel (ash and
carbon).
The chimney has a high
voltage negative grid across it
and this gives the small particles a negative
charge as they go past.
Further up the chimney there are positively
charged plates
which attract the negatively
charged particles.
The particles of pollution build up on the plates
until they are heavy enough to
fall down
into containers.
The containers and the plates are cleaned
periodically.
In this way,
much of the smoky pollution is removed
from the chimney
before it can get out into the
atmosphere.
