Codisposal of coal solid wastes by a granulation/sintering process
Coal cleaning and combustion wastes pose serious environmental problems due to leaching, dusting and smoldering at disposal sites. The wastes can be stabilized by a granulation/sintering process that yields impervious, vitreous granules resistant to environmental degradation. Work is reported for mixtures of coal cleaning waste and power plant fly ash. The sintering is carried out using principally the energy (fuel) inherently present in the cleaning waste. The cleaning waste is from the River King coal preparation plant in Freeburg, IL and the fly ash from the Ottumwa Power Station, Ottumwa, IA. Characterization of the wastes, grinding of the coal cleaning refuse, the formation and testing of green granules for durability, small- and large-scale sintering tests, and evaluation of the sintered granules using standard leaching and freeze/thaw tests are discussed. 13 refs., 6 figs., 6 tabs.
