摘　　要：针对目前日益严格的环保法规和燃煤电厂对增效降耗的需求,提出了一条全新的基于高温除尘的燃煤污染物一体化控制路线并进行工程示范。为分析该新控制路线与现有控制路线在能效上的差异,选取2条现有典型燃煤污染物超低排放路线为对比对象,建立了3层15因素的能效多属性综合评价体系。利用层次分析法确定因素权重,从环保性、技术性、经济性和社会性等评价指标进行了模糊综合评价。结果表明:该新控制路线的综合能效性能更优,具体表现在满足超低排放的环保限值下具有更高的经济性和社会效益;评价结果具体体现了造成某一指标不良的主要影响因素,为工业选择和优化控制路线提供了指导方法。To obey the increasingly stringent environmental regulations and to satisfy the energy-saving and consumption-reducing demand for coal-fired power plants,a new integrated control route was proposed and demonstrated for the pollutants from coal burning based on hot gas filtration.Meanwhile,a three-layer 15-factor comprehensive multi-attribute evaluation system was established to analyze the difference in energy efficiency between the new route and two existing typical ultra-low emission control routes,in which,the factor weight was determined by analytic hierarchy process.Moreover,a fuzzy comprehensive evaluation was conducted from the aspects of environmental protection,technical efficiency,economical efficiency and social benefits of the new route.Results show that the new control route has higher overall energy efficiency,with higher economical efficiency and social benefits under the premise satisfying the ultra-low emission requirements.Simultaneously,the evaluation results reveal the relationship between an indicator and its main influence factors.This may serve as a reference for selection and optimization of similar control routes.
