A high performance KIER-type CYBAGFILTER that combines a fabric filtration and centrifugal dust removal technology was developed to enhance the performance of conventional filtration systems. Based on the performance evaluation results obtained from a pilot-scale test and fluid dynamic computer simulation, a test CYBAGFILTER of 18,000 m3/hr capacity was installed in the clinker calcination process of Ssangyong Cement Co. located at Yongwol, Korea. Membrane filters for surface filtration were applied and evaluated. After 12-month operation, the mean pressure drop was maintained at 70–80 mmH2O, the collection efficiency was more than 99.8%, and the outlet dust concentration was less than 5 mg/Sm3. With an operating pressure drop of 100 mmH2O, the cleaning interval was much longer than that of conventional ones, promising the prolongation of filter life.
