An experimental and thermodynamic equilibrium

The extremely volatile Pb was almost 50% partitioned to the flue gas and fly ash. Zn displays medium volatility and was approximately 50% partitioned to the bottom ash at 850°C. Heavy metals such as Cu and Mn display a refractory volatility, and were primarily partitioned to the bottom ash. For Cu and Mn, 88% were distributed to the bottom ash.

Behaviour of Cd, Cr, Mn, Ni, Pb, and Zn in sewage sludge

As shown in Table 2, the model chemical system includes 14 elements (C, H, N, S, O, Cl, Cd, Cr, Cu, Mn, Ni, Pb, Sn, Zn) representing the input streams of fuel, air, water, organic fraction of the sludge, and heavy metals of interest. To simplify the equilibrium calculations, the major components of the inert fraction of the sludge were neglected.

Coal Bottom Ash for Portland Cement Production

The specific surface Blaine of the cement was 4,050 m 2 /kg fineness of the collected coal fly ash was 3,976 m 2 /kg. The coal bottom ash was ground in a ball mill up to a Blaine fineness of 3,463 m 2 /kg, similar to that of the Portland cement (58% residue on 45 μm sieve).. Several coal fly and ground coal bottom ashes were mixed in the laboratory using a powder mixer.
