“…The dominant PAH was naphthalene, 227 followed by acenaphthylene, phenanthrene and fluorene. Naphthalene is clearly the most 228 abundant product formed during thermal decomposition of different wastes at the same 229 temperature Zhou et al, 2015). This occurred also in residential 230 combustion of MSW and wood where 80% -95% of total PAHs emissions were naphthalene, 231 acenaphthylene, fluorene and phenanthrene (Maasikmets et al, 2016).…”

“…However, incineration is considered to be significant source of 44 emission of PCDD/Fs (Zhou et al, 2015) while landfilling can lead to contaminating the soil 45 and groundwater by the leachate, which contains brominated toxic compounds as well as heavy 46 metals (Akcil et al, 2015;Hadi et al, 2015) and by evaporation of hazardous substances (Guo 47 the material used and the weight percentage of each part.

Combustion and pyrolysis runs at 850 ºC were carried out in a laboratory scale horizontal 10 reactor with different materials combining biomass and waste electrical and electronic 11 equipment (WEEE). Analyses are presented of the carbon oxides, light hydrocarbons, 12 polycyclic aromatic hydrocarbons (PAHs), polychlorinated benzenes (ClBzs), polychlorinated 13 phenols (ClPhs), polybrominated phenols (BrPhs), polychlorinated dibenzo-p-dioxins and 14 dibenzofurans (PCDD/Fs). Results showed that gas emissions were mainly composed of CO 15 and CO 2 ; the high level of CO found in the pyrolytic runs was easily transformed into CO 2 by 16 reaction with oxygen. The total amount of light hydrocarbons emitted was somewhat higher in 17 the samples containing WEEE, methane being the most abundant light hydrocarbon in all the 18 runs. However, the presence of WEEE reduced the emission of PAHs which clearly decreased 19 with the increase of the oxygen. The total amount of BrPhs increased in the decomposition of 20 the samples containing WEEE, reaching its maximum in pyrolysis runs. Emission of PCDD/Fs 21 was enhanced in pyrolytic conditions and they were easily destroyed in the presence of oxygen. 22 23

“…Although dibenzofurans have received considerably less attention from the synthetic community than benzofurans , recent reviews discussing their role as natural products or as environmental pollutants suggest that their relevance as targets for organic synthesis has so far probably been underestimated. Bioactivities and biological sources of naturally occurring dibenzofurans are diverse and range from anticancer activity (e.g.…”

Abstract. The SNCR De-NO x system is an effective denitration technology for MSW incinerator. In this paper, an economic parameter-S: per unit NO x removal cost was established. The results clearly showed that parameter S has a significant change at different loads. The 90% load had the lowest per unit NO x removal cost which was 1.61 RMB/h. It was worth noting that SNCR system had an optimal flow of the reducing agent under different loads. In addition, due to the concentration of NH 3 escape in fuel gas, therefore needs to consider comprehensively the economic and environmental benefits during SNCR operating. These parameters allowed the operator to monitor the SNCR of economic and environmental benefits index more intuitively. With the improvement of technology and experience accumulated, the SNCR technology operation optimization can further reduce NO x in MSW incinerator.
