Abstract

The combustion temperature was controlled between $880^{\circ}C$ to $1070^{\circ}C$ 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 $7.82ng-TEQ/Nm^3$ at $880^{\circ}C$, $6.97ng-TEQ/Nm^3$ at $970^{\circ}C$ and $6.13ng-TEQ/Nm^3$ at $1070^{\circ}C$. Also, The chlorophenols, chlorobenzenes, and PCB concentration decreased by increasing the temperature from $880^{\circ}C$ to at $1070^{\circ}C$, and the isomer of the prescsors had a tendency to emit the higbly cbiorinated compounds.
