THE MODERN TRENDS OF PROCESSING AND USE OF ASH AND SLAG WASTE THERMAL POWER PLANT AND BOILERS
The main problems associated with disposal of ash waste thermal power plants and boilers, and ways to overcome them are examined. It is noted that the most efficient using is utilization of fractions. Coals of Kuznetsk Basin, which are of interest not only because of high chemical and technological characteristics, but also a significant content of valuable metals and components are researched. Analysis of the results determining the chemical composition shows that the ash of Kuznetsk coal rank T refers to the silicate (sour) ashes with high content of Al2O3 and Fe2O3, so one option of utilization is production of aluminum sulfate and argil. The content of ash and slag the metals (calculated as oxides) as Al (22,4%), Fe (9,6%), Ti (0,84%) ensures the profitability of their extraction technology, moreover, that these components contains are predominantly in fine-dispersed fraction which can not be subjected to additional reducing.
