Demonstration of a KIER-type CYBAGFILTER system at the clinker calcinationprocess

A high performance KIER-type CYBAGFILTER that combines a fabric filtration and centrifugal dust removal technology was developed to enhance the perfor mance of conventional filtration systems. Based on the performance evaluati on results obtained from a pilot-scale test and fluid dynamic computer simu lation, a test CYBAGFILTER of 18,000 m(3)/hr capacity was installed in the clinker calcination process of Ssangyong Cement Co. located at Yongwol, Kor ea. Membrane filters for surface filtration were applied and evaluated. Aft er 12-month operation, the mean pressure drop was maintained at 70-80 mmH(2 )O the collection efficiency was more than 99.8%, and the outlet dust conce ntration was less than 5 mg/Sm-3. With an operating pressure drop of 100 mm H(2)O, the cleaning interval was much longer than that of conventional ones , promising the prolongation of filter life.
