<p>The present invention provides an apparatus for producing molten glass, a process for producing molten glass, an apparatus for producing a glass product and a process for producing a glass product, which are capable of preventing deterioration of the quality of molten glass caused by deposition of scattered particles on a furnace wall or a flue. In the present invention, together with the operation of introducing and melting glass material particles 36, 36 ··· by an oxygen combustion burner 22, glass cullet pieces 20, 20 ··· are dropped from glass cullet pieces-introducing tubes 18, 18 ··· to form a substantially cylindrical enclosure around a flame 34 by a flow of glass cullet pieces. That is, glass cullet pieces 20, 20 ··· are dropped from eight glass cullet pieces-introducing tubes 18, 18 ··· to partition off the furnace wall 40 from the flame 34. And, particles 44, 44 ··· scattering from the flame are captured as deposited on the surface of falling glass cullet pieces 20, 20 ··· and dropped into glass melt G in the melt reservoir 12.</p> |
