Abstract | The paper gives results of a comparison of the levels of 14 trace elements in leachates from three types of ash of a common origin coal. The 1-year study was conducted at the Kosovo plant in Obilic, Yugoslavia, comparing coal gasifier ash with fly ash and bottom ash from a coal-fired power plant using lignite from the Dobro Solo mine. Results indicate that levels of Sb, As, Be, Cr, Cu, Pb, Mo, Ni, and Zn in the gasifier ash leachate were similar to those in fly ash leachate. Metal oxides, CaO, MgO, Na2O, K2O, and MnO, in the Kosovo gasifier ash were found at levels similar to those in Kosovo fly ash, and (except for K2O) were about twice those in bottom ash. Concentration levels of all components showed relatively small variations, averaging 50% of their mean annual concentration over the test period. |
