<p>The present invention provides a glass-melting furnace which can suppress deterioration of the quality of molten glass due to exhaust gas, a process for producing molten glass, an apparatus for producing glass products and a process for producing glass products. In a melting tank 12, a leading edge of a glass raw material particle heating unit 18 is disposed on the upstream side in the flow direction of molten glass G, and a flue 28 is disposed on the upstream side of a high-temperature gas phase portion produced by the glass raw material particle heating unit 18, in the flow direction of the molten glass liquid. Glass raw material particles are fed from an oxygen combustion burner 20 of the glass raw material particle heating unit 18, and the fed glass raw material particles are heated and melted by a flame F of the oxygen combustion burner 20, to be liquid glass particles 26, 26···. In such an in-flight glass melting, glass fine particles deviated from the flame F of the oxygen combustion burner 20 and floating in the melting tank 12 are efficiently suctioned through a flue 28 together with the exhaust gas and exhausted to the outside and removed without moving to a wall face of the melting tank 12.</p> |
