Abstract: The specific beech wood dust resistance coefficient values were experimentally determined in the condition of pulse-jet filtration using a pilot-scale baghouse. The experiments were carried out for two variants of the filter medium. One of them had a PTFE (Polytetrafluoroethylene) membrane on the working surface. Three values of filtration velocity and seven levels of dust concentration at the filter inlet were used to determine the variability of the specific resistance coefficient of beech wood dust accumulated on the filter medium. The values of the specific beech wood dust resistance coefficient depend on filter medium finishing and filtration parameters: filtration velocity and dust concentration at the filter inlet. The high concentration of dust at the filter inlet and low filtration velocity should be used, especially in filters with surface finished media, for the reduction in pressure drop, which would affect in a significant reduction of energy consumption.
