【 摘 要 】

The concentration of particulate matter (PM), SO2, NOx, SO3, HCl, HF, and PM2.5 were measured in a 330MW ultra low emission coal-fired power unit. The pollutants emission characteristics and the effect of the conventional pollution control devices on non-conventional pollutants were investigated. The test results show that the concentration of NOx, SO2and PM are 26.9 mg/m3, 18.1 mg/m3, 2.9 mg/m3respectively. The coal-fired power plant, equipped with WFGD and WESP could well control SO3, HCl, HF, and PM2.5 emission from the flue gas. SO3removal efficiency of WFGD and WESP are 42.2% and 82.8% respectively. HCl and HF removal efficiency by WFGD are 90.8% and 91.5% respectively. PM2.5 removal efficiency of WESP is 86.9%.
