摘要: 为了客观地对电力行业清洁燃煤技术进行评估,以及为淘汰小容量机组提供参考,采用多属性综合评估方法构建清洁燃煤发电技术评估体系,从技术、资源消耗、污染物排放以及成本效益4个方面进行综合评估。评估结果表明,整体煤气化联合循环发电技术的环境性能最好,但其成本效益最差。超临界/超超临界煤粉炉机组各方面性能较为均衡。超临界循环流化床机组与超临界煤粉炉机组性能不相上下,前者环境性能较优,后者成本效益较好。

Abstract: In order to objectively evaluate the clean coal utilization technologies in the power industry and provide references for the elimination of small capacity units, the multi-attribute comprehensive evaluation method is used to construct an evaluation system of clean coal power generation technology for comprehensive assessment from the four aspects of technologies, resources consumption, pollutant emissions and cost-effectiveness. The evaluation results show that the integrated coal gasification combined cycle power generation technology has the best environmental performance, but its cost-effectiveness is the worst. The supercritical/ultra-supercritical pulverized coal furnace unit has even performance in all aspects. Compared with the supercritical pulverized coal furnace unit, the supercritical circulating fluidized bed unit is competitive in general performance, especially in environmental performance, while the former one performs better in cost effectiveness.
