摘要
随着《火电厂大气污染物排放标准》(GB 13223-2011)中汞及其化合物的全面实施,我国已全面加强对燃煤电厂的汞排放控制要求。从监测方法选择、采样过程控制、监测结果达标分析等几个方面研究燃煤电厂烟气汞监测排放情况。结果表明:实测的24家燃煤电厂的48台燃煤机组烟气出口汞及其化合物排放浓度范围在0.0692~13.49μg/m^3之间,平均排放浓度为0.6233μg/m^3,远低于排放标准限值30μg/m^3。这说明山西省燃煤机组现有的污染物处理设施的协同控制对降低烟气中的汞排放有较好的作用。
Coal combustion is one of the largest anthropogenic mercury emissions. Mercury and its compounds emission concentration limits in Emission Standard of Air Pollutants for Thermal Power Pants（ GB 13223-2011）is implemented completely. The control requirements of mercury emission from coal-fired power plants has been strengthened in China. The flue gas mercury monitor emission situation of coal-fired power plants are studied from several aspects,such as the choice of monitoring method,the control of sampling process,and the analysis of monitoring results. Monitoring results show that： mercury and its compounds concentration range of 48 coal-fired units of 24 coal-fired power plants between 0. 069 2 μg/m^3 and 13. 49 μg/m^3,the average emission concentration is 0. 623 3 μg/m^3,it far below the emission standard limit 30 μg/m^3. This shows that the cooperative control of the existing pollutant treatment facilities of coal-fired units in Shanxi province has a better effect on reducing mercury emissions from flue gas.
