摘要: 目前火电行业耗煤量约占全国能源消费总量的50%,是大气污染物的重要来源之一。为了更好地实现火电厂大气污染物的近零排放,减轻环境污染,通过对近几年火电厂及全国烟尘、二氧化硫、氮氧化物等污染物的排放量进行对比,分析了火电厂大气污染物减排的必要性和近零排放的概念,特别针对神华煤低灰、低硫、低氮和低汞等特性,研究了火电厂多环节协同除尘、高效脱硫和锅炉低氮燃烧与SCR联合脱硝等集成技术,形成了燃用神华煤火电厂大气污染物近零排放的技术路线和工程应用成果,对实施燃煤电厂大气污染物近零排放具有示范意义。

Abstract: Presently, the coal consumption of coal-fired power generation industry accounts for 50% of the total energy consumption in the country, which makes it the major root of air pollutants. In order to achieve the goal of near-zero emission for coal-fired power plants and alleviate environmental pollution, in this paper, the necessity of emission reduction and the concept of near-zero emission are introduced. In particular, regarding the characteristics of Shenhua coal, such as low ash, low sulfur, low nitrogen and low mercury contents, the study on coordinated dust removal, efficient desulphurization and low-NOx combustion integrated with SCR denitration is conducted, which formulates the technical route for near-zero emission of coal-fired power plants supplied with Shenhua coal. All the applications demonstrate that this technical route is of great significance for near-zero air pollutant emissions from coal-fired power plants.

Key words: coal-fired power plant, Shenhua coal, near-zero emission, technical route, application
