<p><P>PROBLEM TO BE SOLVED: To prevent metal fine particles or the like contained in waste liquid from precipitating to the downside of a glass melting furnace, in the glass melting furnace for treating the waste liquid of high level waste. <P>SOLUTION: Particle-containing molten glass PLG is stored in a treating furnace 14 of the glass melting furnace 10. The particle-containing molten glass PLG is acquired by adding metal fine particles or the like such as ruthenium, palladium or rhodium contained in the waste liquid. When raw material glass and the waste liquid are inputted into the particle-containing molten glass PLG, the raw material glass is melted over the particle-containing molten glass PLG to form molten glass, and a liquid portion in the waste liquid is evaporated to remain the metal fine particles or the like. Namely, new particle-containing molten glass is generated. The particle-containing molten glass PLG stored beforehand in the treating furnace 14 has an apparent density adjusted beforehand so as not to show Rayleigh-Taylor instability between itself and the newly-generated particle-containing molten glass. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
