【摘要】 对于很多企业而言，温室气体与大气污染物之间实际上存在协同效应。在充分调研吉林省某热电企业的减污降碳技改措施的实施情况及其减排效果的基础上，运用了协同控制效应坐标系法、协同效应评估指数法以及污染物减排交叉弹性分析3种评价方法对热电企业已经实施以及拟实施技术的减污降碳协同增效的协同效果评价。发现烟气脱硫和烟气脱硝等超低排放改造措施对污染物有明显的减排作用，但导致CO₂增排，呈现负协同控制效应；以节能为主的汽轮机切缸改造、低压缸零出力技术改造等结构性技术减排措施对CO₂和污染物的减排效果显著。锅炉掺烧煤气改造措施协同减排效果最佳，可以实现减排CO₂236160.00 t/a、减排SO₂ 816.00 t/a、减排NO_x 451.20 t/a、减排烟尘19200.00 t/a。对热电行业减污降碳工作的开展有重要的借鉴意义。更多还原

【Abstract】 There is an obvious synergistic effect between greenhouse gases and air pollutants to many corporations. In this study, three evaluation methods, namely, synergistic control effect coordinate system method, synergistic effect evaluation index method and pollutant emission reduction cross elasticity analysis were used to evaluate the synergistic control effect of pollution reduction and carbon reduction measures in a thermoelectric power company in Jilin Province. The results showed that the end-of-pipe measures such as desulfurization, denitrification and other ultra-low emission retrofit measures have obvious reduction effects on pollutants, but lead to the increasing of CO₂ emission and show a negative synergistic control effect. Structural technical reduction measures such as energy-saving-based steam turbine cylinder cutting transformation, low-pressure cylinder zero-output technology transformation and other structural technical reduction measures have significant reduction effect on emission of CO₂ and pollutants. The best measure is boiler doping gas transformation which can achieve annual reduction of 236,160.00 tons of CO₂, SO₂ reduction of 816.00 t/a, NO_x reduction of 451.20 t/a and soot reduction of 19200.00 t/a. This study can provide an important reference for pollution reduction and carbon reduction in the cogeneration industry.更多还原
