Abstract

The combustion temperature was controlled between <TEX>$880^{\circ}C$</TEX> to <TEX>$1070^{\circ}C$</TEX> to find the relation the combustion temperature and emission amount of PCDDs/PCDFs in the Municipal solid waste incinerator. The emission amount of PCDDs/PCDFs decreased when the temperature increased in the rear of the boiler. The PCDDs/PCDFs concentration were detected <TEX>$7.82ng-TEQ/Nm^3$</TEX> at <TEX>$880^{\circ}C$</TEX>, <TEX>$6.97ng-TEQ/Nm^3$</TEX> at <TEX>$970^{\circ}C$</TEX> and <TEX>$6.13ng-TEQ/Nm^3$</TEX> at <TEX>$1070^{\circ}C$</TEX>. Also, The chlorophenols, chlorobenzenes, and PCB concentration decreased by increasing the temperature from <TEX>$880^{\circ}C$</TEX> to at <TEX>$1070^{\circ}C$</TEX>, and the isomer of the prescsors had a tendency to emit the higbly cbiorinated compounds.
