It was presented that both morphology and proportion of TG)试验。研究发现：不同温度成灰的形貌及元素比例均存 elements of different temperature ashes were significantly 在较大差异，成灰过程均未出现熔融结渣。但按煤质熔融特 different, melting and slagging didn’t appear in the process of 性指标进行理论计算的结果表明各温度成灰均已严重结渣， ashing. But according to the melting characteristics index of 而灰熔点烧结仪试验发现各成灰温度灰样其变形、软化、半 coal quality, it showed that the ashes had serious slagging 球和流动温度一致，均高于1 100 ℃。对灰样进行TG 实验， tendency. Meanwhile, it was found that the deformation, 表明1 100 ℃以后不同温度成灰的组分已一致，各温度成灰 softening, hemispherical and fluid temperatures were consistent 灰样含相同的起骨架支撑作用的高温熔融物质。XRF 分析 in sintering test and were all above 1 100 ℃. TG results showed 数据显示：随着成灰温度
