Phase Relation of Secondary Fly Ash in Incineration Processes of Municipal Wastes

摘要

Oxychloride systems are very important in the disposal of ashes generated from municipal wastes. The alkali metal-oxychloride system is a basic system of secondary fly ash generated in this process to reduce the volume of bottom ash and fly ash from incineration processes. Toxic materials such as compounds of heavy metals and dioxin may be absorbed by or contained in the secondary fly ash. In this study the themochemical properties of the NaCl-Na2CO3 system was examined by EMF method using -Al_2O_3 as a solid electrolyte at from 800K to 1200K.
