Abstract
To promote the utilization of waste material as alternative fuel, the mono- and co-combustion characteristics of sewage sludge (SS) and coal gangue (CG) were systematically investigated, with emphasis on environmental influences. The emission of SO2, NOx as well as the trace elements during combustion of SS and CG were studied with regard to the effects of their chemistries, structures and interactions. Results showed that co-combustion can be beneficial for ignition performance. A synergic effect on both desulfurization and denitrification can be expected at ca. 800 °C. Further, an enhanced retention of trace elements during co-combustion was also observed, especially for Pb and Zn. On the basis of the results, it can be expected that, with proper operation, co-combustion of SS and CG can be a promising method for the disposal of these two wastes.
