Research on Combustion Ash of Adzuki Bean Harvest Residue Biocoke

Abstract

In this study, a high-density solid fuel (Biocoke) was used, which was produced using discarded azuki bean harvest residue as the main raw material. And rice bran was mixed in various proportions as the sub raw material. Here, adzuki bean harvest residue is a herbaceous biomass with high ash content. These Biocoke and wood pellets were mixed and burned in a household pellet stove, and the resulting combustion ash was compared. These results suggest that Biocoke made primarily from adzuki bean harvest residue has the effect of suppressing the formation of caking clinker (suppressing melting). It was also found that the mixing ratio of rice bran results in differences in the formation of caking clinker (has an effect of improving characteristics). The composition of combustion ash obtained from comparative combustion experiments was analyzed. And some substances were detected that raise concerns about the effective use of combustion ash.
