Co-firing characteristics of corn stalk and stone coal in different proportion were investigated by thermal gravimetric analysis. The results showed that corn stalk can improve the ignition and combustion of stone coal. The agglomeration experiments on corn stalk were made in a bench-scale bubbling fluidized bed with quartz sand as bed material and stone coal ash as additive. The results indicate that stone coal ash can inhibit agglomeration of bed material particles at temperature of 900℃. Agglomerate of blends was analyzed by means of scanning electron microscopy, energy-dispersive X-ray, and the bed materials were analyzed by means of X-ray fluorescence. Analysis showed that aluminum element and iron element in stone coal ash can react with alkali compounds and eutectics with low melting point, form a covering layer with high melting point on the surface of biomass and quart sand particles, thus inhibit the forming and transfer of low melting compounds.
