A manufacturing method of a granulated body, a manufacturing method of fusion glass, and a manufacturing method of a glass article

Japanese Patent JP5954319

B2

To provide a process for producing granules, wherein a component in an exhaust gas discharged from a glass melting furnace can be reused as a raw material for alkali-free glass, and a heating and drying step is not required for the reuse. Exhaust gas G1 formed in a process for melting a raw material of glass containing a boron component is brought in contact with contacting liquids L1 and L2 to obtain treated liquids S1, S2 and S3 having the boron component in the exhaust gas G1 dissolved therein; magnesium hydroxide is added to the mixture of the treated liquids in a treated liquid tank 14 to obtain a liquid containing a boron component and a magnesium component; by using the liquid, a granulation liquid is prepared; and in the presence of the granulation liquid, a raw material mixture for producing alkali-free borosilicate glass is granulated to produce granules.
