Abstract

Abstract

Coal combustion is one of the largest anthropogenic mercury sources，the control requirements of mercury emission from coal-fired power plants has been strengthened in China． The research summarized and analyzed the mercury emission data from 32 units of 16 coal-fired power plants in China． The results revealed that the range of mercury mass balance from 70% to 130% was reasonable; through pollution control equipment average of more than 70% mercury in the flue gas went into the fly ash and gypsum，average less than 30% mercury in the flue gas went into the external environment; SCR could promote the mercury removal efficiency; the average mercury removal efficiency of ESP/FF and FGD were 38. 5% and 52. 5% respectively; the average mercury removal efficiency through total cooperative control equipment was 74. 1%，the study illustrated cooperative control of existing coal-fired units pollutant treatment facilities had a good effect to reduce mercury emissions．
