In this study, the effects of can velocity on the performance of a pilot-scale bag filter dust collector were examined. Test bag filters were made of polyester fabric and had a 156 mm diameter and a 3 m length. The cleaning interval of the pulse-jet cleaning system and the effects of inlet particle concentration with various can velocities were considered. When the dust collector was operated with insufficient can velocity, an unreasonable increase in the cleaning interval was observed. The cleaning interval decreased with the increased can velocity. Furthermore, under the unsuitable can velocity condition, the increasing tendencies of the cleaning interval and dust emission by decreased inlet particle concentration deviated from the expected theoretical tendency. Therefore, the appropriate can velocity should be selected in a pilot-scale experiment for improving the prediction of actual-scale dust collector performance. (C) 2017 Elsevier B.V.
