    摘要
  • 摘要: 为全面表征某600 MW超低排放燃煤机组的Hg分布特征及迁移、释放规律,开展了现场实测研究。结果表明:煤中Hg含量的平均值为310 μg/kg,炉渣、粉煤灰、石膏、废水、烟气中Hg的分布系数分别为1.9%、37.5%、34.6%、0.8%、24.8%;整个烟气治理系统的总Hg脱除效率为74.7%,最终总Hg排放为6.0 μg/m3,SCR脱硝、烟气冷却器对Hg0转化效率分别达到44.2%、30.4%,低低温电除尘器几乎实现Hgp完全脱除,WFGD对Hg2+脱除效率达到80.7%;该电厂Hg一次释放量达到783 kg/a(其中,大气直排188 kg/a),二次释放量为334 kg/a。该成果可为燃煤电厂烟气Hg排放控制标准出台及控制技术的选择提供借鉴。
    Abstract: In order to characterize the Hg distribution characteristics, migration and its release rules of a 600MW unit ultra-low emission coal-fired power, field measurement research was conducted in this paper. The results showed that, the mean value of Hg content in coal was 310μg/kg, and the distribution coefficients of Hg in slag, fly ash, gypsum, waste water and flue gas were 1.9%, 37.5%, 34.6%, 0.8% and 24.8%, respectively. The removal efficiency of Hg in the whole flue gas treatment system was 74.7%, and final total Hg emission was 6.0 μg/m3. The conversion efficiency of SCR and flue gas cooler on Hg0 were 44.2% and 30.4%, respectively. The removal efficiency of HgP in LL-ESP was nearly 100%, and the removal efficiency of Hg2+ in WFGD was 80.7%. The primary release of Hg from the power plant was 783 kg/a (with atmospheric emission of 188 kg/a), and the secondary release was 334 kg/a. This paper could provide references for the release of Hg emission control standards and selection of control technologies for coal-fired power plants.
