摘要
为了解生活用蜂窝煤氟含量水平及氟排放率,以北京市大兴区黄村镇的前辛庄、后辛庄和周村3个自然村为研究对象,在2012年3个月取暖季内,针对蜂窝煤及煤渣中的氟含量分别进行了测定。结果表明:三个村庄蜂窝煤样品的w(F)均值为277.8μg/g(N=46),高于我国工业原煤w(F)平均值(约83μg/g);生活燃烧蜂窝煤氟排放率为61.6%,显著低于蜂窝煤汞排放率99.75%及电厂等工业燃煤氟排放率(80%~99%)。鉴于生活用蜂窝煤多为富氟的劣质煤,其氟含量高于工业原煤,而排放率却低于工业用煤排放率,因此不宜采用工业用煤w(F)平均值及工业燃煤氟排放率来计算民用蜂窝煤的氟排放量,有必要展开单独研究。
To investigate the fluorine content and emission rate in domestic honeycomb briquette, fluorine concentration of honeycomb briquette and cinder samples in Qian Xinzhuang Hou Xinzhuang and Zhou Cun,Da Xing district,Beijing during supply heating in March, 2012 was determined.The results showed that the average fluorine concentration in honeycomb briquette samples was 277.8 μg/g （N=46）,which was significantly higher than that in the industry coal in China （about 83 μg/g）.Fluoine emission rate of domesitic honeycomb briquette was 61.6%, which was significantly lower than that of mercury emission rate and fluoine emission rate of industrial coal （80%~99%）.In view of the domestic coal found mostly inferior and its fluorine content are higher than the industrial coal but fluorine emission rate lower than that of industrial coal, the measuring and quantification method of fluorine emission from domestic coal should not comply to the mean fluorine content of industrial coal and that of fluorine emission rate, but a independent approach should be established.
