| Popis: | Generally, coal-fired incinerators are characterized by a high combustion temperature and a well-equipped flue gas cleaning system. Co-combusting municipal solid waste (MSW) in coal-fired incinerators can reduce the emission of PCDD/Fs and help to enhance the treatment capacity of the MSW; more importantly, this approach provides a new orientation for upgrading and transitioning old coal-fired power plants. In this study, the simulated municipal solid waste (SMSW) is mixed with coal in proportions of 0 (without addition), 7.5, 15, 20, and 25 wt.% and then co-combusted in a drop-tube furnace. The PCDD/Fs emitted in both the flue gases and fly ashes from the combustion tests are well investigated. In the present study, the I-TEQ concentration of the PCDD/Fs in the flue gas can meet the emission limit (0.1 ng I-TEQ/Nm3) when MSW is co-combusted at less than 20 wt.%. The concentration of the PCDD/Fs in the fly ash is much lower than the permitting standard for disposal in sanitary landfill sites (3.0 ng I-TEQ... |
