摘要

Comparative silicate analysis data on the distribution of the main ash-forming elements of Kaa-Khem coals in fly ash and slag from the Kyzyl heat and power plant in 1989-2009 heating seasons are presented. The degree of binding of SO_2 from industrial smoke emissions increased in this two-decade time interval. The distribution of six main ash-forming elements between slag and fly ash is uneven: silicon, iron, manganese, and sulfur are concentrated in the slag. Fly ash is enriched in aluminum, titanium, and unburned carbon. The concentrations of alkali metals and calcium in the slag and fly ash are almost the same. The low-sulfur ash-and-slag waste of the Kyzyl heat and power plant with high silicon, aluminum, iron, calcium, and unburned carbon contents can be recommended as a raw material in the production of building materials, wall ceramics, and porous fillers, for road building, etc. The ash dump is of practical interest in terms of the extraction of valuable ferromagnetic materials (magnetite and ferrosilicon) and aluminosilicate micro-spheres.
