摘　　要：应用于电厂的烟气二氧化碳捕集技术是能实现大规模降低二氧化碳排放的主要手段之一。文中从二氧化碳捕集系统与电厂系统集成角度出发,分别从烟气、汽水循环、冷却水等3个系统分析了捕集系统对电厂的影响及可以采取的集成及改造措施。结合660 MW超超临界机组进行二氧化碳捕集前后的模拟计算,考察二氧化碳捕集对电厂的影响,结果表明,全烟气中90%的二氧化碳捕集后电厂发电净效率降低约10个百分点。CO2 capture technology in power plants is one of the main methods to reduce carbon dioxide emissions on large scale. From the perspective of system integration between CO2 capture and power plant, based on flue gas, steam cycle and cooling water system, the influence and potential integration and retrofit actions on power plant were analyzed. A 660 MW ultra-supercritical unit was simulated in the aspect of without and with carbon capture alternatively, the impact and influence from carbon capture to power plant were studied. The results show that the whole net power generation efficiency is reduced by about 10 percent after 90 percent of the carbon dioxide been captured.
