The Ames Laboratory granulation/sintering process for the stabilization of coal cleaning refuse is being adapted to the codisposal of refuse and power plant combustion wastes. The combustion wastes are fly ash, flue gas desulfurization sludge, and liquid wastes from the regeneration of ion exchange beds, the cleaning of boiler internals, and boiler blowdown. A plan of work was developed that calls for the batch preparation of green granules of sufficient durability and for sintering of the granules to attain high strength. A second phase of the work will involve continuous agglomerator runs to produce granules for large scale sintering and subsequent leaching and freeze/thaw testing. Suitable solid raw materials were identified and fully characterized. The level of grinding of the coal refuse required for granule formation was determined.
