A study has been conducted on the vaporization behavior of nine trace elements including Be, V, Cr, Mn, Co, Ni, Zn, As, Pb in coal combustion and pyrolysis below 1150℃. Zn, Pb and As showed greater volatility than the rest of trace elements but their vaporization behaviors strongly depended on the atmosphere and heating rate. It was found that carbon and mineral matter in coal played an important role in the vaporization of these three elements.
