The partitioning of trace elements and the influence of the feed conditions (50:50 coal/ petcoke feed blend and limestone as fluxes) was investigated in this study, using feed fuel, fly ash and slag samples from the 335 MW Puertollano IGCC power plant (Spain) collected under different operational conditions. The partitioning of elements in this IGCC plant may be summarized as follows: a) High volatile elements (70->99 % in gas phase): Hg, Br, I, Cl and S, b) Moderately volatile elements (up to 50% in gas phase and >60 % in fly ash): As, Sb, Se, B, F, Cd, Tl, Zn and Sn, c) elements with high condensation potential:(>90 % in fly ash): Pb, Ge, Ga and Bi, d) elements enriched similarly in fly ash and slag 30-60 % in fly ash: Cu, W, (P), Mo, Ni and Na and e) low volatile elements (>75 % in slag): Cs, Rb, Co, S, K, Cr, V, Nb, Be, Hf, Ta, Fe, U, Ti, Al, Si, Y, Sr, Th, Zr, Mg, Ba, Mn, REEs, Ca and Li. The volatility of As, Sb, and Tl and the slagging of S, B, Cl, Cd and low VE are highly influenced by the fuel geochemistry and limestone dosages, respectively. | |
