| 中文摘要 |
| 为减缓气候变化、实现电力行业清洁高效发展，需大力推进燃煤电厂减污降碳. 引入在线监测数据，构建2020年山西省燃煤机组大气排放清单，基于SBM-DDF模型评估燃煤机组环境效率和大气排放物减排潜力. 结果表明：①2020年山西省燃煤机组SO2、NOx和PM的排放浓度范围分别为1.73~28.22、 3.11~43.57和0.78~7.39 mg·m-3，已达到超低排放限值要求，CO2、SO2、NOx、PM排放量分别为27 074.21×104、 2.12×104、 5.34×104和0.43×104 t. ②山西省燃煤机组的环境效率平均值为0.71，其CO2、SO2、NOx和PM减排潜力分别为11 190.35×104、 1.26×104、 3.22×104和0.25×104 t，可实现减污降碳协同增效，但协同水平较低. ③将供热量指标纳入投入产出指标体系，会降低燃煤机组环境效率，表明机组当前在热电联产运行方面效率较低. ④从装机规模和锅炉类型角度，小型机组和煤粉锅炉机组的污染物减排潜力较大. |

| To mitigate climate change and achieve clean and efficient development in the power sector， it is imperative to vigorously advance pollution and carbon reduction in coal-fired power plants. By incorporating online monitoring data， this study constructs an atmospheric emission inventory for coal-fired units in Shanxi Province for the year 2020 and evaluates their environmental efficiency and emission reduction potential using the SBM-DDF model. The results indicate that： ① In 2020， the emission concentrations of SO2， NOx， and PM from coal-fired units in Shanxi Province ranged from 1.73-28.22， 3.11-43.57， and 0.78-7.39 mg·m-3， respectively， already meeting ultra-low emission standards. The total emissions of CO2， SO2， NOx， and PM were 27 074.21×104， 2.12×104， 5.34×104， and 0.43×104 tons， respectively. ② The average environmental efficiency of coal-fired units in Shanxi Province was 0.71， with reduction potentials for CO2， SO2， NOx， and PM amounting to 11 190.35×104， 1.26×104， 3.22×104， and 0.25×104 tons， respectively. This indicates synergistic benefits in pollution and carbon reduction， albeit at a relatively low level of synergy. ③ Incorporating the heat supply indicator into the input-output framework reduced the environmental efficiency of coal-fired units， suggesting current inefficiencies in combined heat and power operation. ④ From the perspectives of installed capacity and boiler type， smaller units and pulverized coal boiler units exhibited greater potential for pollutant emission reduction. |
