针对13种可能的洁净煤高效发电技术路线,分析对比各技术路线的发电效率、经济性、污染物排放等指标,并建立了能源可持续发展综合指标(energy sustainable development compositive index,ESDCI)。分析不同的指标权重对ESDCI的影响;并基于我国2030,2050年能源利用的不同情景,分析、预测不同发电技术的ESDCI变化趋势。研究结果指出:2030,2050年超超临界燃煤发电机组(ultra-supercritical pulverized coal power plant,USCPC)是电力工业最主要的高效洁净利用技术;如果采用二氧化碳捕集技术(carbon capture and storage,CCS)技术,多联产+CCS、USCPC+CCS以及整体煤气化联合循环发电系统(integrated gasification combined cycle,IGCC)+CCS是较好的选择。研究成果为确定我国煤炭高效洁净化利用的技术途径提供了参考。
According to 13 possible clean coal efficient power generation technology routes, the indicators such as power generation efficiency, economy and pollutant emission of each technology route are analyzed and compared, and the energy sustainable development compositive index (ESDCI) is established. Analyzes the influence of different indicator weights on ESDCI, and analyzes and predicts the ESDCI trend of different power generation technologies based on different scenarios of energy use in 2030 and 2050 in China. The results show that the ultra-supercritical pulverized coal power plant (USCPC) is the most efficient and clean technology in the power industry in 2030 and 2050. If carbon capture and storage (CCS) ) Technology, polygeneration + CCS, USCPC + CCS and integrated gasification combined cycle (IGCC) + CCS are the better options. The research results provide a reference for determining the technical ways of efficient and clean utilization of coal in our country.
