Abstract:
Different sam ples o f road dust a re taken in N an jing c ity. Co rresponding exper im ents on pa rtic le d iam e ter and e lem en tal com ponents of these samp les are perform ed to obta in distributions o f particle d iam eters, elem enta l com ponen ts and leve ls. Low-ca lo rie-v alue o f arrived basis and fracta l d im ension o f road dust are com puted and analyzed where lowca lo rie-va lue o f arrived basis ranges from 5 385.0 kJ /kg to 7366.6 kJ /kg and fracta l dim ension fluctuates between 2.302 and 2.541. Th is prov ides fundam en tal informa tion for direct ene rgy utilization and san itary landfill of road dust.
