Abstract:
Agglomeration is a serious problem for gasification and combustion of biomass in fluidized bed. Agglomeration characteristics may be affected by gas condition, but the literature is quite vague in this regard. This study focuses on the effects of gasification and combustion condition on agglomeration tendency with two types of biomass ash, including rice straw and wheat straw ash. The agglomerates are analyzed by SEM-EDS for morphology and elemental composition. Defluidization temperature (Td) in those two types of gas conditions is quite different. Td in gasification condition is much lower than that in combustion condition. Agglomeration in both combustion and gasification conditions are melting-induced, the lower Td in gasification condition may be caused by the transformation of K2SO4.
