摘要
研究了煤粉在氮气氛和空气气流中的热分解特性及添加助燃剂的影响。结果表明，煤粉在燃烧条件下挥发分的析出量超过在氮气氛下的产率，煤粉燃烧过程中挥发分的析出燃烧碳与残碳的燃烧并存。助燃剂的种类和加入量对煤粉热分解的催化作用有很大影响，浸渍６％左右的Ｆｅ（ＮＯ３）３可使双鸭山烟煤和阳泉无烟煤的挥发分产率分别增加１０．７％和５．２％
The pyrolysis of pulverized coal(PC)in nitrogen
atmosphere and hot air flow and effect of additional chemical combustionsupporting agents was
investigatedThe results showed that the volatile matter yield of PC in combustion is higher than
that in nitrogen,the devolatilization and char combustion are processed simultaneously The
effect of various additions on pyrolystic characteristics of PC is remarkableThe addition of Fe
(NO3)3 in 6 % increases volatile matter yield of bituminous by 107 % and anthracite by 52 %
