测试结果表明，影响后燃现象的主要因素是给煤的粒度分布、煤挥发分含量及挥发分析出规律，同时与炉膛内总风量、一二次风量的配比有关。
The test shows that size distribution of feeding coal, volatile content and its release as well as the total air rate and primary air ratio will influence the post combustion in CFB boiler.
煤的粒径对挥发分氮析出作用明显，煤粉越细，挥发分氮转化率越高。
The more finely pulverized coal has more higher conversion rate of volatile nitrogen.
实验表明：神华煤液化残渣的燃烧是分两步进行的，在低温段主要是神华煤液化残渣中挥发性的气体急剧析出，引起燃烧失重；
Test result showed that combustion of Shenhua coal liquefaction residuals proceeds in two stages a low and a high temperature stage.
