摘要/Abstract

摘要： 无论是从包括颗粒物、SO₂、NO_x等单个大气污染物控制而言，还是系统的燃煤电厂超低排放控制技术，目前都有较为成熟且较为多元化的可选技术，在具体工程自身实际情况具体分析的基础上进行选择。对于燃煤电厂非传统大气污染物，需要重点关注SO₃、氨、重金属的排放与控制。对燃煤电厂SO₃、氨、重金属的产生、危害和控制3个方面进行分析，在此基础上从防治技术政策、排放控制标准、控制技术路线、工程示范等4个方面提出燃煤电厂非传统大气污染物控制政策建议。

Abstract: In terms of the control of individual atmospheric pollutants, such as particulate, sulfur dioxide and nitrogen oxides, or the systematic ultra-low emission control technology of coal-fired power plants, there have been a variety of mature and diversified technologies available to be selected on the basis of specific analysis of the actual project situation. For non-conventional atmospheric pollutants in coal-fired power plants, it is necessary to pay more attention to the emissions of sulphur trioxide, ammonia and heavy metals. In this paper, the generation, hazard and control of sulphur trioxide, ammonia and heavy metals in coal-fired power plants are analyzed respectively. On the basis of this, some suggestions on the control policy of unconventional air pollutants in coal-fired power plants are put forward from four aspects, i.e., prevention and control technology policy, emission control standard, control technical route and engineering demonstration.

Key words: coal-fired power plants, ultra-low emission, non-traditional air pollutants, SO₃, NH₃, heavy metal
