Test and Study on Synergic Mercury Removal Performance of Environmental Protection Facilities at Ultra-Low Pollutants Emission

doi:10.11930/j.issn.1004-9649.201707168

Abstract

Abstract: The test on mercury emission and distribution is carried out synchronously at multi-points in some ultra-low pollutants emission power plants. It is discovered that the mercury removal efficiency by WFGD is about 22.2%~80.35% and that by WESP is about 0%~71.4%. The mercury removal efficiency by WFGD is correlative to the mercury morphology at the entrance of WFGD, the unit load and the gas-liquid mass. WESP shows limit effect on the mercury capture when the mercury concentration at the entrance of WESP is low.

Key words: coal-fired power generation unit, thermal power generation, flue gas, ultra-low emission, synergism, mercury capture
