    摘要： In a glass melting furnace, a radiation screen wall is installed between a melting area and a refining area with a refining bank. This radiation screen wall leaves a flow path above the melt surface of the glass bath for the return flow of at least part of the combustion gases from the refining area to the melting area. In order to suppress a return flow of already refined and very hot glass melt from the refining area into a melting area, but still allow the charging material to melt completely as early as possible, the furnace is operated to produce at least one upward current between the middle of the melting area and the front face of the refining bank in the glass melt. Within the glass melt and before the melt surface is reached, this upward current is divided into a first partial current which flows upstream into the melting area and a second partial current which flows downstream over the refining bank, whereby a return current of the glass melt from the refining area into the melting area is prevented by the second partial current flowing downstream. This upward current is achieved by the use of one or more of the following arrangements: a row of bubblers; a step projecting upwards from the furnace bottom; and/or at least two heating electrodes which are installed before the front face of the refining bank.

    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.
