Release of accumulated dust from the rigid candle filter surface has been
extensively studied both theoretically and experimentally, especially for the
case of pulse jet type cleaning. However, it is still unclear which is the most
effective parameter to the release of accumulated dust. In this study, behaviors
of released dust and pressure inside and outside the filter element were
observed very precisely. Based on the observation, a simple model correlating
between momentum acting on released dust, pressure and, shear and tensile
stresses has been proposed. Then its validity was discussed by comparing
calculated and experimental results.
