In this study, we analyzed emission characteristics of correlation coefficient PCDD/Fs and Co-PCBs from high temperature incineration. PCBs low concentration ranges 17.8 to 49.6ppm as less than 50ppm and high concentration ranges 167.0 to 684.6 ppm as more than 50ppm. In high capacity incineration, PCDD/Fs and Co-PCBs correlation coefficient was 0.278, and low capacity incineration was 0.850. Non PCBs feeding condition PCDD/Fs and Co-PCBs correlation coefficient was more than 0.9 in WHB and stack. PCBs feeding conditions(low, high concentration PCBs) are different results in WHB which is represent at 0.494, 0.255, respectively. But, in stack PCDD/Fs and Co-PCBs correlation is similar about 0.8 as higher.
