removal of particles and dust collection from pyrolysis

poly-generation system of CFB combustion/coal pyrolysis. The GBF was applied to the dust removal of coal pyrolysis products by using CFB ash as solid heat carrier. By applying the model calculation of C. Tien et al.26 into the lab-scale continuous experiment of the dust removal in GBF, the pressure drop and size distribution of dust particle were examined
