Polychlorinated Biphenyls Incineration

China PCBWin Technology Co.,Limited | Updated: Nov 10, 2016

This method is considered to be the best approach, but must be on a dedicated complete decomposition of polychlorinated biphenyls in efficient incinerators, not just burnt. Feel free to burn PCBs may produce more toxic than polychlorinated biphenyls polychlorinated dibenzo-p-dioxins (PCDD), polychlorinated dibenzofurans (PCDF), and so on. In order to guarantee the total elimination of PCBs, and tight control over the burning conditions. United States Environmental Protection Agency provides: at the time of burning PCBs, temperature should be higher than 1150 ℃, in the combustion chamber residence time greater than 2 s, excess amount of oxygen is greater than 3%, the CO content in the exhaust gas shall be less than 100 ppm. In addition, Canada and the United States and Sweden respectively in cement kiln destruction of polychlorinated biphenyls in test results show that cement kilns can meet the requirement of elimination of polychlorinated biphenyls.
