Coal gasification waste products, including those from Lurgi gasification, have different properties from the combustion ashes, especially with respect to mineralogy. To date, comparatively little effort has been directed toward the investigation of bulk utilization. A Gas Research Institute project (1) was directed towards correction of that deficiency by matching properties of the Great Plains Gasification Plant Gasifier Ash (GPGA) and the Antelope Valley Power Plant combustion ash (AVS) with existing practiacl economic possibilities. This paper summarizes three years of bulk utilization research on the GPGA gasifier ash and the AVS scrubber and bottom ash. The following options were explored: mineral wool, sulfur concrete, high-flexural-strength ceramics, dual concrete replacement, and road stabilization. Where possible, standard ASTM procedures were followed. For most of the options investigated, considerable time was saved by drawing on previous experience in the UND testing laboratory. Efforts were concentrated towards utilization of the ashes in products that would be economical on a full-scale basis. Mineral wool was formed by blowing air on molten ash generated with an outdoor pilot plant cupola, as well as an electric arc rocking laboratory furnace. Modified sulfur and ash mixtures were heated, mixed, and formed into suitable specimens for flexure and compression testing.
