CHARACTERIZATION OF THE FLOWABILITY OF BIOMASS-COAL BLENDED POWDERS

摘要

(1) The blended powders of RH with SBC has the best flowability,rnfollowed by the blended powders of SS with SBC, and the blendedrnpowders of RS with SBC has the worst flowability.rn(2) As the biomass mass fraction increases, the flowability of RSrnand SBC blended powders become worse gradually; while as thernbiomass mass fraction increases, the flowability of RH/SBC blendedrnpowders and SS/SBC blended powders first become better and thenrnbecome worse. There seems to exist a critical biomass mass fractionrncorresponding to the best flowability for these blended powders.rn(3) As the biomass particle diameter increases, the flowability forrnthe blended powders of SS with SBC become worse gradually in ourrnexperimental range.
