| 摘 要： | 煤灰在高温下的热行为对气化过程有很大的影响.利用热重-差示扫描量热(TG-DSC)、X-射线衍射(XRD)和扫描电镜(SEM)研究了义马煤中矿物质在高温氧化气氛下的热行为及矿物质演变.结果表明,矿物质组分随温度的升高发生了转变,主要由硅铝酸盐控制,这种改变会对灰熔融特性产生影响;矿物质形貌和分布状态随温度的升高也发生了变化. |
| 关 键 词： | 煤灰 高温 热分析 X-射线衍射 扫描电镜 |

| Abstract: | Gasification process is influenced by thermal behavior at high temperature.TG-DSC,XRD and SEM were employed to observe phase changes and reaction of mineral under oxidation atmosphere.There is different mineral changing in heating process which affects the ash fusibility.The system of mineral matters is mainly dominated by the change of aluminosilicate.The morphology and distribution of mineral are changed at elevated temperature. |
| Keywords: | ash high temperature TG-DSC XRD SEM |
