    摘要： In a process for vitrifying heavy-metal-containing residues having a chlorine content above 10% by mass, in particular from flue gas cleaning, which are melted in a melting furnace, the constituents which cannot be incorporated into the melt are separated in the main furnace into two fractions, the first fraction comprising the readily volatile components and the second fraction comprising the salt-like less volatile components, and the first fraction is evaporated off, conducted out of the furnace together with the exhaust gas and collected as condensate, and the second fraction is separated from the surface of the melt as liquid salt and is discharged.

    摘要： An electrically heated tank furnace is used to melt glass whereby a floating gall layer is formed on the melt, in particular during the vitrification of hazardous materials such as asbestos, fly ash, filter dust, whereby the tank of the furnace is fitted with a discharge outlet for the melt and an overflow channel with an inlet for the gall. A stream of ascending gas bubbles is produced in the melt. In order to promote better and automatic draining of the gall the stream of gas bubbles is produced directly in front of the overflow channel which thereby maintains a layer of liquid gall in the overflow channel and a layer of molten glass retained by a weir on the bottom of the overflow channel. The temperature in the overflow channel is chosen to be above the melting temperature of the gall, whilst the bottom layer of glass is maintained at a temperature at which the viscosity of the glass is so high that the glass does not drain out the overflow channel.

    摘要： A silica-rich, volatiles-deficient surface layer is removed from highly viscous glass, near a forming means (rolls or the like). There is used a weir of less-than-usual depth that contains a platinum member that provides a substantially unchanging weir depth; at the same time, Venturi means control the amount of hot gases removed from the glass-melting furnace, to maintain or control the flow of the highly viscous glass. With the invention, it is possible to drain off the silica-rich surface of a highly viscous glass, losing only about 10 percent of the furnace throughput, rather than accepting the higher losses (about 30 percent) required in accordance with previous practices.

    摘要： Apparatus for separating surface glass from a parent body of molten glass flowing through a forehearth and, thereafter, removing such surface glass from the forehearth. A stationary skimmer is positioned in the forehearth to interfere with or divert the flow of the surface glass and thereby separate such glass from the remainder of the parent body thereof. The skimmer has an upper portion having a horizontal planar configuration of a truncated triangle with the truncated face being on the upstream face of the upper portion. The upper surface of the upper portion is above the surface level of the glass. A lower ledge portion located below the surface level of the glass, projects upstream from the truncated face. The flow of the separated surface glass then being directed through one or more suitable channels or passages which extend from a region adjacent the upstream face of the upper portion of the skimmer and along a side of the upper portion to the exterior of the forehearth to effect removal of such glass therefrom.
