| Summary: | The coal ashrepresents an important industrial waste source. The most important waste produced by the energy industry is the ash resulted of coal burning into the large combustion plants. The physical and chemical properties of ash vary substantially between producers and depend on the quality andthe composition of coalthat are used in modern power plants, as well as on combustion conditions. The diverse chemical, mineralogical and morphological properties of ash offer an opportunity to process it and recover various fractions with particular attributes. The main constituents are Al2O3, Fe2O3, CaO, MgO andin smaller quantities Na2O and K2O. Also, the ash from burning lignite of the Oltenia mining field has an important coalchar content, which could be exploited. In this work will be presented some results ofspecific investigations, which allow the rational regarding recovery of coal char from ash. |
