Technology For Producing Mineral Fibers By Recycling Ash-Sludge And Oil-Shale Wastes

The technology for recycling ash-sludge and oil shale wastes using an electro-plasma facility in the production of mineral fibres, for melting silicate-containing materials, and schemes for additionally heating the silicate melt stream at the exit from the melting furnace is described. Studies of the electro-plasma facility and raw material as well as the mineral fibres obtained with their use have been performed.
