摘　　要：对燃煤电厂汞的形态转化及其影响因素的研究进展进行综述,并对该领域今后的研究提出看法。根据已有研究,煤中汞的存在形态以及煤和烟气中的含氯物质、硫化物、NOx、含氧量等是影响汞形态转化的化学因素;脱硫装置、除尘装置、选择性催化还原(SCR)脱硝装置等烟气净化装置也对汞的形态转化有影响。The progress in study on state transformation of mercury and it＇s affecting factors in coalfired power plants has been summarized,and points of view in research of this area in the future being put forward. According to the research already performed, the existential state of mercury in coal, the content of chloride, sulfide, NOx and oxgen etc. ,are chemical factors for state transformation of mercury,the flue gas purication facilities, such as flue gas desulphurization system, dust removal scrubber, and SCR denitrification system,etc. ,also affect the state transformation of mercury.
