ABSTRACT:
A method and means for producing mineral wool from coal slag is described wherein molten coal slag is transferred from a coal slag tank in an electrical generation plant. The molten coal slag is transferred to a fiberization apparatus and is heated during the transfer process to maintain the coal slag in a molten state. In the fiberization apparatus, the molten coal slag is subjected to compressed air streams which creates mineral wool fibers which are collected in a collection apparatus.
