| 中文摘要 |
| 在德国NETZSCH公司生产的STA 409C型热天平联合德国BRUKE公司生产的EQUINOX55傅里叶红外光谱仪上(TGA-FTIR),对合山高硫煤4种不同粒径煤样的硫释放特性进行了燃烧实验研究,重点研究了超细化煤粉(0～20μm)的自脱硫特性及加入脱硫剂CaO时的脱硫特性.结果表明不加脱硫剂时,超细化煤粉(hs10.90)燃烧生成的SO2气体总量比其它较大颗粒的煤粉燃烧生成的SO2气体的总量小.以CaO作脱硫剂钙硫摩尔比(Ca/S)为3的情况下,超细化煤粉(hs10.90)燃烧生成的SO2气体总量比其它较大颗粒的煤粉燃烧生成的SO2气体的总量小得多.超细化煤粉的优越脱硫特性为煤粉燃烧过程中的直接固硫提供了新的思路与途径. |
| 英文摘要 |
| Micro-pulverized coal(0～20μm) combustion is a new kind of pulverized coal combustion technology. Four Heshan sulfur coal samples with different mean particles diameter were combusted, using a TGA-FTIR made in Germany. Micro-pulverized coal self desulfurization and adding CaO desulfurization characteristics were investigated. Experimental result proved that micro pulverized coal SO2 emission was less than coarse particles, and with the same Ca/S molar ratio 3 micro-pulverized coal can obtain higher sulfur capture efficiency. Its unique desulfurization property provide a new idea path for reduce sulfur releasing from pulverized coal combustion. |
