Gas phase migration of Cl during thermal conversion of municipal solid waste
In the paper, the gas phase migration of chlorine during thermal conversion of municipal solid waste (MSW) is studied by using tube furnace. The results indicate that with the increase of temperature and residence time, the HCl released by MSW containing organic chlorine (PVC) and inorganic chlorine (NaCl) increased during the thermal conversion, in addition, during the thermal conversion of NaCl and PVC, the release of HCl mainly ended after 20 and 15 min, respectively. Different chlorine sources and oxygen concentration affect different HCl conversion rates, and the increase of oxygen concentration can effectively promote the release of HCl. With moisture content increasing in MSW, the HCl conversion rate of NaCl and PVC during thermal conversion was below 4.5% and 94%, respectively.
