LOW-VISCOSITY REGULATION METHOD FOR DISCHARGING MELT OF INCOMBUSTIBLE WASTE

摘要

PROBLEM TO BE SOLVED: To provide a low-viscosity regulation method for discharging a melt of incombustible waste, capable of ensuring PTM operation stability and keeping a melt viscosity of glass or slag as a final product as low as 100 poise or less at a discharge portion temperature (1300°C to 1500°C) by developing glass/slag composition process necessary for vitrification of high-viscosity waste.SOLUTION: A low-viscosity regulation method for discharging a melt of incombustible waste according to the present invention includes: maintaining a change in composition by adding an oxide composition regulator to an oxide composition containing 40wt% or more of SiOand included in incombustible waste at a melting temperature of 1500°C; and regulating a low viscosity of the incombustible waste to 100 poise or less.
