摘　　要：采用经济学成本分析法对集成碳捕集封存技术(CCS)的1000 MW超超临界燃煤机组进行技术经济性分析,以供电成本、净现值、动态回收期及内部收益率为评价指标,探究了煤炭价格、碳配额交易价格、碳税、通货膨胀率及CO_(2)售卖价格的影响。结果表明:CCS碳捕集装置建设成本较高,较常规机组总投资增加约24.54%,CCS系统能效惩罚较大,厂用电率增加19.31百分点;常规机组供电成本为0.3075元/(kW·h),CCS机组的供电成本增加35.87%;CO_(2)减排成本为171.47元/t;CCS机组净现值为138.06亿元,为常规机组的2.23倍;CCS机组的动态回收期为4.15 a,较常规机组提前1.94 a;综合考虑碳税、碳配额交易及CO_(2)售卖时,CCS机组的供电成本为0.1964元/(kW·h),较常规机组低43.17%;在碳交易、碳税政策和CO_(2)循环再利用市场完善建立后,CCS机组具有更强的盈利能力。The economic analysis of a 1000 MW ultra supercritical coal-fired plant integrated carbon capture and storage(CCS)system was carried out using economic cost analysis.And the evaluation criteria of power supply cost,net present value(NPV),dynamic payback period and internal rate of return were taken as evaluation indicators to investigate the impact of coal price,carbon trading price,carbon tax,inflation rate and CO_(2)price.Results show that the construction cost and energy consumption of plant integrated CCS system(PICCS)are relatively high,and the total investment and power consumption rate are 24.54%and 19.31%higher than that of the conventional unit.The power supply cost of the conventional unit is 0.3075 yuan/(kW·h).The power supply cost of the PICCS is 35.87%higher than the conventional unit.The cost of CO_(2)emission reduction is 171.47 yuan/t.The net present value of PICCS is 13.806 billion yuan,which is 2.23 times than that of the conventional unit,meanwhile,the dynamic payback period of the PICCS is 4.15 years,which is 1.94 years earlier than that of the conventional unit.Considering carbon tax,carbon trading and CO_(2)sales simultaneously,the power supply cost of the PICCS is 0.1964 yuan/(kW·h),which is 43.17%lower than that of the conventional unit.After the establishment of carbon trading,carbon tax policies and the CO_(2)recycling market,the PICCS is more profitability than the conventional unit.
