| 1 | Evaluation of mercury speciation and removal through air pollution control devices of a 190 MW boiler显示文摘Air pollution control devices(APCDs) are installed at coal-fired power plants for air pollutant regulation.Selective catalytic reduction(SCR) and wet flue gas desulfurization(FGD) systems have the co-benefits of air pollutant and mercury removal.Configuration and operational conditions of APCDs and mercury speciation affect mercury removal efficiently at coal-fired utilities.The Ontario Hydro Method(OHM) recommended by the U.S.Environmental Protection Agency(EPA) was used to determine mercury speciation simultaneously at five sampling locations through SCR-ESP-FGD at a 190 MW unit.Chlorine in coal had been suggested as a factor affecting the mercury speciation in flue gas;and low-chlorine coal was purported to produce less oxidized mercury(Hg2+) and more elemental mercury(Hg0 ) at the SCR inlet compared to higher chlorine coal.SCR could oxidize elemental mercury into oxidized mercury when SCR was in service,and oxidation efficiency reached 71.0%.Therefore,oxidized mercury removal efficiency was enhanced through a wet FGD system.In the non-ozone season,about 89.5%-96.8% of oxidized mercury was controlled,but only 54.9%-68.8% of the total mercury was captured through wet FGD.Oxidized mercury removal efficiency was 95.9%-98.0%,and there was a big difference in the total mercury removal efficiencies from 78.0% to 90.2% in the ozone season.Mercury mass balance was evaluated to validate reliability of OHM testing data,and the ratio of mercury input in the coal to mercury output at the stack was from 0.84 to 1.08. | Chengli Wu Yan Cao Zhongbing Dong Chinmin Cheng Hanxu Li Weiping Pan | 2010 | Journal of Environmental Sciences2010，22，2： | 13 |
