Melting raw materials for glass or the like using solid fuels or fuel-batch mixtures.

摘要

Thermally fusible material such as glass batch is liquefied using a solid carbonaceous fuel such as coal as the major energy source. In another embodiment, solid or liquid fuel is mixed with the batch material being fed to an initial liquefaction stage. Melting may be advanced further In a subsequent stage where the melt may also be re-oxidized.
