Abstract: | Gamma-ray spectrometry (GS), energy dispersive X-ray fluorescence (EDXRF) analysis methods and wavelength dispersive X-ray
fluorescence (WDXRF) were applied for the studies of some coal components, e.g., sulphur, light and heavy metal element concentrations
and naturally occurring radioactive isotope contents. Hundred fifty coal samples originating mostly from eight different coal
mines from Upper Silesian Coal Basin and 150 samples of ash obtained from these coal samples in laboratory by total combustion
at final temperature of 820°C, were analyzed. Such comparitive analyses can be helpful in selection of most suitable kind
of coal for burning in electrical power and heat plants to minimize the environmental pollution. |
