VITRIFICATION OF ASBESTOS WASTE |
摘要 |
Waste asbestos is converted into a glass by maintaining within an electrical glass melting furnace a body of molten glass at a temperature above the decomposition temperature of asbestos; supplying asbestos to the furnace; and withdrawing molten glass from the furnace at a temperature of at least 1000.degree.C The asbestos is advantageously mixed with cullet and a melt accelerator and fed into the furnace by means of a screw mixer/conveyor. The furnace is advantageously operated at a pressure less than atmospheric pressure. |
