Fluorine Emission of Pulverized Coal-Fired Power Plants in China

  • 摘要: 选择我国4家电厂的6台煤粉锅炉,进行了烟气以及飞灰、底渣、脱硫石膏等燃煤副产物样品的采集和F(氟)含量分析,考察燃煤电厂F排放特征. 结果表明:经过烟气除尘、脱硫及脱硝装置后,烟气中氟化物浓度明显降低; 除尘器主要脱除烟气中颗粒态F,静电除尘器对烟气中氟化物的总脱除效率为19.50%~36.59%,布袋除尘器的脱除效率略高于静电除尘器;石灰石-石膏湿法脱硫装置可协同脱除烟气中94.19%的氟化物. 燃煤中的F经过燃烧和烟气净化装置后,有0.83%~3.37%由底渣排放;1.20%~2.00%转移到脱硫废水中;13.45%~33.80%转移到飞灰中;59.60%~79.66%转移到脱硫石膏中;只有2.04%~5.00%通过烟囱排入大气.
