Abstract:
Granular bed filters have shown high collecting efficiency for separating particles from flue gases at high temperatures. This paper presents the experimental results from laboratory investigations of a new louver design for the Panel Bed Filter. A filter unit has been built which uses filter trays and is designed for a volume flow of 1 m3/h (S.T.P.). Alumina spheres with a diameter of 662 m were used as the granular media. The unit has been tested using standard ISO 12103-1 particles with a diameter of 12.6 m with good results. The paper compares the performance of the filter tray design with the wishbone and L10-56 designs in addition to the performance of commercial bag house filters in terms of clean dust emissions, pressure loss and cleaning frequency.
