摘要
在德国NETZSCH公司生产的STA 4 0 9C型热天平联合德国BRUKE公司生产的EQUINOX5 5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～ 2 0 μm)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 (hs1 0 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 (hs1 0 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 .
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 SO 2 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.
