The designed high efficiency cyclone gives an efficiency
of 91.1 % as against the desired 90 % which is safe design for
controlling air pollutant concentration in the form of SPM
from kiln attached to the cement plant. The monitored PM
concentration is 1250 mg/Nm3 withoput control and with
91.1 % efficiency, the outlet emission after control would be
111.25 mg/m3, which is much safer as against the mandatory
standards of 150 mg/m3.
