Strumienie wejściowe (węgiel, mączka kamienia wapiennego, woda procesowa) i wyjściowe (popioły lotne z 3 stref odpylania, żużel, gips, osad i odciek z odsiarczania spalin) zostały poddane analizie elementarnej w celu sporządzenia bilansu materiałowego 58 pierwiastków. Materiały pochodziły z bloku energetycznego wyposażonego w 3-strefowy elektrofiltr i system mokrego odsiarczania gazów spalinowych...
A study was undertaken to evaluate the distribution of Al, As, Cr, Cu, Fe, Mn, Ni, Pb, Ti, V and Zn in fly ashes collected in the electrostatic precipitator of a thermal power plant in San Nicolás (Argentina). Five samples were collected during one week of operation. For the fractionation, the scheme applied consisted in extracting the elements in four fractions namely (i) soluble and exchangeable...
The determination of selenium in solid materials related with the use of coal for energy production was evaluated by two methods; ICP-MS and HG-ICP-MS. Coals, fly ashes and various solids used as sorbents in gas cleaning processes (kaolin, limestone, alumina, metal oxide mixtures and activated carbons), were the materials analysed. In several of these materials, selenium could be determined by either...
