Abstract. Objective of this work is to study ash composition after the coal incineration in thepower stations for its further complex processing and obtaining a low-ash carbon part with furtherits use as a hard fuel for the heat-and-power stations and as silicate mass suitable for the building industry. The necessity of complex method for ash processing arises from researches, which showed the ash multi-element composition. Additionally to processing of dry daily ash, there is a strong need in processing the wet dumps, which should be dewatered and processed by a complex method. An important factor, while processing the dry ash, is ceasing increment of fly-ash dumps. Besides, the gained experience and improved technology of the dry fly ash complex processing will allow to effectively master technology for the dump ash processing. Therefore, development of technology for the dry fly ash processing acquires the primary importance.
Keywords: ash, carbon, processing, dehydration, complex method.
