摘　　要：富氧燃烧被认为是一种具有发展潜力的碳减排技术,是目前国内外研究的主要碳减排技术之一。燃煤燃烧引起的污染物排放一直是当前研究的热点问题,针对富氧燃烧方式,概述了当前富氧燃烧技术中燃煤烟气的污染物,如硫氧化物、氮氧化物、粉尘和重金属汞等的排放特性。在富氧燃烧方式下,硫氧化物、氮氧化物和烟尘的排放量会减少,而重金属汞的排放量会增加。As a carbon emission reduction technology, oxy-fuel combustion is considered potential and researched widely at home and abroad. Pollutants emitted from coal combustion were always a heated issue at present. The paper summarized the research of pollution characteristics emitted from oxy-fuel combustion, such as nitrogen oxides, sulfur oxides, dust and mercury. In oxy-fuel combustion mode, the emission of nitrogen oxides, sulfur oxides and dust was decreased, but the emission of mercury was increased.
