摘　　要：介绍了一种远程在线测量锅炉烟气中的超细粉尘和多环芳烃的方法。该法通过专用的稀释装置对在线取样得到的烟气进行稀释,然后利用电晕和光电的方式使颗粒带电,最后通过测量电流得到细颗粒的数量和PAHs的大小。作者利用该方法对鼓泡床锅炉排放的超细粉尘、PAHs及烟气成分等进行了长时间的远程在线测试研究,并分析了该锅炉所排放的超细颗粒、PAHs与烟气成分及其他物理参数的关系。The paper introduces one method for remote online measuring the submicron particles and PAHs of the flue gas from boiler. The procedure for it is to dilute the sampled gas, charge the particles in the gas by the photoelectric and corona principle respectively, and then measure the current to achieve the amount of submicron particles and PAHs. By using the method the emissions of submicron particles, PAHs and gas components from the bubbling fluidized bed combustion boiler are measured and studied. Additionally the correlation among the submicron particles, PAHs, gas components and temperature are analyzed in this paper. Figs 8 and refs 8.
