Emissions minimization of chlorinated micropollutants in coal solid waste co-combustion by primary measures

The primary measures technique which causes inhibition of the formation of chlorinated micropollutants in coal solid waste was studied. A series of experiments were performed for prevention of polychlorinated dibenzo-p-dioxins (PCDD)/ polychlorinated dibenzofurans (PCDF), polychlorinated biphenyls (PCB), and polychlorinated benzenes (PCBz) formation by the use of inhibitors of thermally resistant in-organic compounds added to the fuel before combustion. The fuel types used were lignite coal from Puertollano, pretreated municipal solid waste and polyvinyl chloride (PVC). The result shows that all N- and S-containing substances are able to reduce strongly PCDD/F, PCB, and PCBz fuel gas emission if used as a 10% additive of fuel.
