| description | The burning of fossil fuels for energy purposes causes pollution of all
environmental factors. If water and soil pollution is practically as significant both in the process
of burning fuels and in the process of extraction and transport, air pollution is generated mainly
by their combustion. The burning of fossil fuels in thermal power plants pollutes the atmosphere
with a series of gaseous emissions such as oxides of carbon, nitrogen and sulfur and to a lesser
extent with volatile organic compounds. Apart from these pollutants, if the fuel used is coal, then
the atmosphere is also polluted with airborne substances.
Electrofilters are installations that use electrostatic forces to separate particles suspended in
gases. The fundamental processes that take place in electrofilters are: the initiation of corona
discharge, the charging of aerosols with electric charge, the kinetics of particles, the collection
and evacuation of dust. In general, aerosols have a certain natural electrical charge (due to
ionization processes, in flame or by friction), but this is much too small for efficient separation.
The most efficient method of artificially charging electrically charged particles in a biphasic
medium is to pass the gas through an electrode system, between which the electric field is strong
enough to initiate corona discharge. The particles are subjected to ion bombardment, thus being
charged with electric charge. The duration of this process is of the order of 0.01 seconds. |
