摘要： Methods and apparatus provide for: feeding glass batch material into a plasma containment vessel in such a way that the glass batch material is dispensed as a sheet of glass batch material particles; directing one or more sources of plasma gas into the inner volume of the plasma containment vessel in such a way that the plasma gas enters the plasma containment vessel as at least one sheet of plasma gas; and applying an alternating electric field to facilitate production of a plasma plume within the inner volume of the plasma containment vessel, where the plasma plume is of dimensions sufficient to envelope the sheet of glass batch material particles, and is of sufficient thermal energy to cause the glass batch material to react and melt thereby forming substantially homogeneous, spheroid-shaped glass intermediate particles.

摘要： In the manufacturing of high melting point glasses with volatile components, in particular of glasses from the group of boron glasses and borosilicate glasses, a furnace is provided that has a superstructure, fossil fuel burners, and a melting tank. In front of a conditioning zone and a throat leading to an extraction zone, a step-shaped raised area in the bottom is provided which is formed continuously over the complete width of the melting tank. In order to suppress segregation or, respectively, phase separation, to protect the furnace construction materials and to enable problem-free operation, a temperature of at least 1600.degree. C. is produced in the superstructure by means of oxygen-rich oxidation gas, a raised area is provided in the form of a refining bank with a step in front of it, the step being at least 150 mm high and from which at least one row of booster electrodes projects upwards, before the step, the melt flows over at least one row of bubblers located in the bottom, and behind the step, the glass flows in a highly heated state over the refining bank for a distance of 800 mm to 2000 mm, the upper side of said bank being at a maximum distance "T" of 300 mm from the glass bath surface.

摘要： A method for manufacturing glass wherein raw material is fed as a batch to a continuous glass-melting tank furnace, melted in a melting tank and passed to a refining tank via a submerged throat. The melt is heated in the refining tank to de-gas it, and then molten refined glass is delivered to a conditioning tank where it is brought to a desired working temperature. The refining tank is divided into upstream and downstream refining cells by a transverse sill. The melt in the upstream refining cell is heated to create a spring zone located towards the downstream end of that cell and a circulation of melt in that cell which feeds the spring zone.

An electric circuit means comprising at least two interconnected electrodes is pulsated on and off at predetermined time intervals in order to establish the desired temperature profile within the molten glass mass.

摘要： An electric melting furnace is described for melting high electrical resistivity glass, such as E-glass, within a melting chamber surrounded by a relatively low electrically resistivity refractory, such as chromic oxide refractory, by utilizing interconnected peripherally positioned batch electrodes at substantially the same potential as the chromic oxide walls and centrally positioned electrodes which are immersed a greater distance than the batch electrodes. A quiescent zone is formed adjacent a lower portion of the melting chamber and the batch blanket and effective hydrostatic head of the molten bath are adjusted by controlling the immersion of the batch electrodes within the molten bath.
