Heavy metals distribution in gas and solid phases during refuse derived fuel incineration

Using the self-made experimental device, when MSW RDF was incinerated at temperature of 500 degrees C similar to 900 degrees C for 60min, Hg almost evaporated into the gas phase. With the increase of incineration temperature, concentration of 6 kinds of heavy metals in the gas phase increased and in the solid phase reduced significantly. The addition of 5% chlorine can make the concentration in gas phase of 8 kinds of heavy metal increased and heavy metal content of Zn, Cu, Pb, Cd, Hg in the solid phase decreased sharply. When the content of organic chlorine increased to a certain extent, no-volatile heavy metals such as Ni, Cr, concentration in the gas phase increased by about 30%. Compared with adding 5% PVC, the difference of adding 10% PVC is not significant. For Pb, Zn, concentrations in the gas phase increased and in the solid phase decreased slightly with water increasing, but effects on Cu were smaller, while on Hg, Cd, Ni, Cr, almost no effects.
