With the development of the economy and society in China, the production of municipal domestic waste is rapidly increasing, and the harmless treatment of domestic waste, especially the reduction of dioxins, has been a major research challenge. A new technical proposal of flexible coupled disposal of domestic waste by anaerobic pyrolysis was proposed for a 2×55 MW coal-fired unit for the first time. The industrial experiment of coupled co-disposal of wasteanaerobic pyrolysis products was carried out, and the dioxins generation and emission characteristics of this coal-fired unit were mainly tested. It[JB(][XCp.tif]s proved that the process proposal cannot only realize the co-disposal of domestic waste, but also ensure the normal operation of the system self-balancing when the coal-fired unit is shut down for maintenance.The results show that the dioxins content generated by waste treatment using this process route is much lower than that generated by direct waste incineration.When pulverized coal is burned, the mass concentration of dioxins in flue gas is 6.05×10-3 ng/m3 (calculated by TEQ, the same below). When the garbage coupling ratio is 4%, the mass concentration of dioxins in the flue gas is 5.34×10-3ng/m3. The mass concentration of dioxins in the final flue gas is 1.145×10-2 ng/m3 and 1.074×10-2 ng/m3 respectively after the maximum conversion of dioxins mass concentration emitted by waste pyrolysis oil and gas combustion.There is little difference in dioxins content in flue gas between waste mixed combustion and pure coal combustion, and they both meet the requirements of dioxins emission limit of 0.02 ng/m3 in the Emission Standard of Air Pollutants from Coal-fired Coupled Sludge Power Plants in Shanghai.The study show that when the anaerobic pyrolysis coupled disposal process is adopted, the proportion of waste coupling is controlled to be less than 4%, and the dioxins emission in the flue gas of coal-fired coupled waste will not increase significantly.
