摘　　要：在 0 2 5MW燃烧试验台上进行黑液水煤浆燃烧过程中氟的排放特性研究 ,并和普通水煤浆进行对比 ,分析了影响排放过程的各因素 .试验表明水煤浆中的氟含量较低 ,一般小于 30mg/kg ,普通水煤浆燃烧氟排放率为 70 %～ 90 % ,排放浓度为2 0～ 2 6mg/m3 ;黑液水煤浆氟排放率明显低于普通水煤浆 ,为 4 5 %～ 80 % ,排放浓度为 1 7～ 3 0mg/m3 .炉膛温度和水煤浆成分对氟排放浓度有一定的影响 .The paper is about the emission of fluorine from an experimental boiler of 0.25 MW when burning black liquor coal-water slurry (CWS). The result is compared with CWS. And the analysis of effect factors is also carried out. Experimental research show that, the content of fluorine in CWS, which was less than 30 mg/kg, was relatively low. The emission ratio and concentration of fluorine were 70%～90% and 2.0～2.6 mg/m3 respectively when burning common CWS; while the data of those when combusting black liquor CWS were 45%～80% and 1.7～3.0 mg/m3 respectively. The hearth temperature and the element of CWS were two factors of emission fluorine when burning CWS.
