72 コークス実画像におけるデジタルイメージ強度評価(コークス強度,熱分解)

抄録

In this study, coke strength for actual microscopic structures is numerically evaluated by means of digital-image based modeling. Stress analyses with a homogenization method for microscopic structures of coke are carried out. In the analyses, microscopic structure of coke is assumed to be composed of active components and pores. The stress analyses are carried out for two cokes made from a caking coal and a coke made from a slightly caking coal. Analytical results show that the stress distributions are changed bythe connectivity of coke matrices.
