【摘要】 采用Ｍａｌｖｅｒｎ 公司的马尔文粒度仪测量煤粉颗粒的平均粒度和粒度分布、及Ｌｅｃｏ 公司的ＭＡＣ－ ５００ 型工业分析仪测量煤粉的工业分析成分， 对合山劣质烟煤、晋城贫煤的各４ 种不同粒径的细化和超细化煤样进行了试验研究， 应用库仑滴定法测定了煤粉颗粒粒度对煤质全硫元素分析的影响． 结果表明， 煤粉颗粒粒度对煤质分析特性有很大的影响， 并进一步影响煤粉的热解、着火、燃烧等特性． 煤粉颗粒粒度是进行煤质分析与燃烧系统设计的重要物理参数．更多还原

【Abstract】 Experimental investigation and theoretical analyzing has proved that there are great influence of particle size on compositions analyzing characteristics, and till further influence pyrolysis, ignitability, combustion and burnout characteristics Pulverized coal particle size is a very important physical parameter for compositions analyzing characteristics and its combustion system design Experimental investigations are based on four different particle size coals taken from Heshan and Jincheng respectively, their particle size analysis by Malvern grain structure analysis apparatus, their proximate analysis by MAC-500 meter, their total surfer analysis by coulometry titration更多还原
