| 摘 要： | Study on behavior of chlorine contained in oval-shaped densified refuse derived fuel (d-RDF) prepared from municipal solid waste in pyrolysis was carried out by means of temperature-programmed electrical furnace, and the gas evolving from pyrolysis was investigated by FFIR. De-HC1 rate was calculated by determining the emission fraction of HC1 in the flue gas and the fraction of C1 left in the pyrolysis residue. The results show that C1 in the d-RDF releases primarily in the form of HC1 during the pyrolysis, and the initial releasing temperature of HC1 enhances with the increase of heating rate. Meanwhile, the higher the end temperature of pyrolysis, the more the C1 released. De-HCl rate is about 70% when the end temperature of pyrolysis is around 600℃. Besides, mechanism of C1 release is discussed.

| Abstract: | Study on behavior of chlorine contained in oval-shaped densified refuse derived fuel (d-RDF) prepared from unicipal solid waste in pyrolysis was carried out by means of temperature-programmed electrical furnace, and the gasevolving from pyrolysis was investigated by FTIR. De-HCl rate was calculated by determining the emission fraction of HCl in the flue gas and the fraction of Cl left in the pyrolysis residue. The results show that Cl in the d-RDF releases primarily in the form of HCl during the pyrolysis, and the initial releasing temperature of HCl enhances with the increase of heating rate. Meanwhile, the higher the end temperature of pyrolysis, the more the Cl released. De-HCl rate is about 70％ when the end temperature of pyrolysis is around 600℃. Besides, mechanism of Cl release is discussed. |
