Title:
Melting kiln, melting method, and manufacturing method of non-alkali glass plate
Document Type and Number:
Japanese Patent JP6292090
Kind Code:
B2
Abstract:
Provided is a fusion method and a manufacturing method for an alkali-free glass pane. According to the fusion method, raw materials of glass are fused in a melting furnace. The melting furnace comprises a first chamber, in which the raw materials are input, a first chamber combustor, a second chamber receiving melted glass formed by fusing the above raw materials supplied by the first chamber, a second combustor and a throat portion connecting the lower portion of the first chamber and the lower portion of the second chamber. The raw materials are raw material of alkali-free glass with 54-73 mass % of SiO[2] and 0.1-12 mass % of B[2]O[3]. The above first chamber combustor and the second chamber combustor use an oxy-fuel combustion combustor or an air combustion combustor. 50-100% of the total burning calories per hour of the first chamber combustor are generated by the oxy-fuel combustion combustor. 75-100% of the total burning calories per hour of the second chamber combustor are generated by the air combustion combustor.
