waste coal from thermal plants

An overview of metals recovery from thermal power plant solid wastes - ScienceDirect

As coal is burned in a power plant, its noncombustible mineral content is partitioned into bottom ash, which remains in the furnace, and fly ash, which rises with flue gases. Two other by-products of coal combustion air-pollution control technologies are flue gas desulfurization (FGD) wastes and fluidized-bed combustion (FBC) wastes.

PDF Solid Waste From the Operation and Decommissioning of Power Plants

The two largest forms of solid waste from coal-fired generation are coal ash (from the combustion of coal), and "scrubber" slurry (from environmental controls at the plant). Collectively, these two wastes are called coal combustion residues, or CCRs. CCRs are the second most abundant waste material in the United States, after household waste.
