Abstract
The solution of applications for air pollution control in foundries for
iron and non-ferrous metals may not only be understood as the
observance of requested emission limit values at the stack outlet. An
effective environmental protection already starts with the greatest
possible capture of pollutants at the source with at the same time
minimisation of the volume flow necessary for this. Independent of this,
the downstream installed filtration system has to realise a degree of
separation of definitely above 99%.
Furthermore, when selecting the filter construction, attention has to be paid
to a high availability. An even temporarily production
without filter will more and more no longer be accepted by residents and
authorities. Incidents at the filter lead to a shutdown of the whole
production.
Additional measures for heat recovery while preparing concepts for filtration
plants help to reduce the energy consumption and serve
for a sustained conservation of environment. A consequent consideration of the
items above is also condition for the fact that environmental protection
in foundries remains affordable. The lecture deals with the subjects above
from the point of view of a plant constructor.
