ABSTRAKT

Co-combustion of coal with sludge did not result in greater NOx, SO2, HCl, and CO emissions. Sludge raised heavy metals emitted, especially Cd, Pb, and Hg, mostly associated with particles greater than 1 μm. Metals were retained in bed ashes and in the cyclones and most of the Hg was adsorbed in fly ashes. The leachability of metals and organic matter decreased with combustion. Results of acid neutralization capacity showed that ashes became more resistant to acidification than the parent sludge. Globally, this study shows that combustion of sludge can reduce environmental impact compared with the traditional direct use of sludge in soils.
