Kind Code:
A
Abstract:
A process for recovering the byproducts of a process that burns coal and for reusing the byproducts is disclosed. The process includes the steps of identifying a disposal site that contains the byproducts (typically fly ash and bottom ash), removing at least a portion of the byproducts from the disposal site, analyzing a sample of the portion of the byproducts to determine the loss on ignition of the portion of the byproducts, introducing the portion of the byproducts along with pulverized coal into a pulverized coal furnace if the portion of byproducts have a loss on ignition greater than or equal to a predetermined loss on ignition value (typically greater than or equal to 1 to 5 %), and burning the portion of the byproducts in the furnace with the pulverized coal to render the byproducts into a commercially valuable fly ash and bottom ash having very low loss on ignition, typically lower than 3 %.
