  • J056012 Carbonization and combustion properties of high density and high compressive strength biomass solid fuel

抄録

Recently, biomass attracts much attention as a renewable energy resource. Biocoke, hereinafter called BIC, is one of the solid biomass fuels which is made from woody or herbaceous biomass by heating and compressing process. BIC is expected to be an alternative to coal cokes and a high energy density solid fuel because it has high hardness and high density. In the present study, the carbonization and combustion properties of a green tea BIC and a cypress BIC are experimentally examined. The experimental results show that the carbonization yield of the BIC is higher than that of raw woods in spite of the same material. Further, the weight reduction curve during the combustion process of the BIC carbide is similar to that of hard charcoal when the carbonization temperature is higher than 673 K. Consequently, it is considered that the BIC can maintain adequate hardness even if it is carbonized at the upper portion of a cupola furnace, and burns as an alternative to coal coke in the coke bed at the bottom of the cupola furnace.
