| 摘 要： | 利用综合热分析仪研究了Ce2(CO3)3, CeO2, CaCO3, CaO 四种化合物对煤粉燃烧过程的影响. 重点研究了稀土金属化合物Ce2(CO3)3在不同添加量和不同粒度时对煤粉燃烧过程的影响. 结果表明，Ce2(CO3)3能够显著促进煤粉的燃烧过程，降低着火点温度. 添加量为1.0%时，煤粉着火温度降低约30℃，助燃性能优于其他3种催化剂. 在添加量小于1.0%时，Ce2(CO3)3添加量越大，着火温度越低. 在Ce2(CO3)3不产生团聚的情况下，催化剂粒径越小，煤粉的着火温度越低.

| Abstract: | The effects of Ce2(CO3)3, CeO2, CaCO3, CaO, four kinds of catalysts, on combustion property of pulverized coal were investigated with a synthetical thermal analyzer, especially the influences of addition content and particle size of Ce2(CO3)3 powder during the combustion process of pulverized coal. The results show that Ce2(CO3)3 powder can increase the combustion process of pulverized coal, and lower its ignition point temperature. The pulverized coal ignition temperature can be reduced about 30℃ when the addition content of Ce2(CO3)3 powder is 1.0%. With the addition content of Ce2(CO3)3 powder increasing and its particle size decreasing, the catalytic effect becomes more eminent when its addition content is less than 1.0%. |
