Abstract

During the production of
energy from large combustion plants will cause the combustion process to air
pollution stands out various gases. That gases are quite harmful on the urban
ecosystem. Wet flue gas desulphurisation systems are preferred because of their
applicability and easily operable structures without a deep information. The
Station flue gas purification systems are designed as a gas desulphurisation
process. Each of these units has their own chimney and fluepurification
systems. In flue gas purification systems, SO₂, SO₃, dust
and heavy metals are purified. SO₂ which occurs by fuel burning can
be increased in flue gas purification systems with 98% efficiency. The process
is worked on the basis of spraying the lime milk produced by grinding the
limestone in the mill and mixing it with water, into the waste gas in the
washing tower. The lime milk polluted after spraying process is segregated by
way of hydro cyclones and discarded. The lime milk which diminishes is taken
from the stock tank and given to the system. SO₂ gas which enters in
the flue gas purification system can be increased to 500 mg/Nm³. It
is seen how important the gas desulphurisation process in preventing
environment pollution and for a healty landscape. This study has been presented
at the II. International Sustainable Buildings Symposium in the same form.
