Glass melting furnace, the method of manufacturing a molten glass, glassware manufacturing apparatus, and a method of manufacturing a glass product
2010
The present invention provides a glass melting furnace capable of suppressing the quality degradation of the molten glass caused by the exhaust gas, the method of manufacturing a molten glass, glassware manufacturing apparatus, and a method of manufacturing a glass product. In the melting tank 12, the tip of the glass material grains heating unit 18 is installed in the upstream side of the flow direction of the molten glass G, the flow direction of the glass melt than hot gas phase portion formed in the glass raw material particle heating unit 18 flue 28 is disposed on the upstream side. With dropping glass raw material particles from the oxygen combustion burner 20 of the glass material grains heating unit 18, and melted by heating the glass raw material particles in the dropping by the flame F of the oxygen combustion burner 20, the liquid glass particles 26, 26 and to. In such airborne when melted in the melting tank 12, the glass particles to float dissipated from the flame F of the oxygen combustion burner 20 without toward the furnace wall of the melting tank 12, efficiently from the flue 28 with the exhaust gas It is sucked in and exhausted removed to the outside.
