| 从下面的图也可以看出，煤样中的酸碱氧化物的含量变化是直接导致煤样灰熔温度变化的原因，熔点较高的碱性氧化物使棋盘井和雀儿沟煤样中的灰熔温度很高，与其在硅铝比大小关系不大。酸性氧化物和碱性氧化物含量的比值在一定范围内可以预测灰熔温度。 从表看到，上海庙煤样的硅铝比较高，且SiO2和Al2O3的总含量占煤灰80%以上，其碱性氧化物含量在三种煤样中最低，占总含量的8.5%，但是雀儿沟和棋盘井煤样中的碱性氧化物含量很高，其中CaO的含量分别达到4.35%、9.12%，CaO自身的熔点较高，其熔点为2610℃，这可能是导致煤样的灰熔温度过高的原因。 |

It can also be seen from the figure below that the change in contents of acid and alkali oxides in the coal sample is the direct cause to changed ash fusion point of the sample. The high melt point of alkali oxides result in very high ash fusion points for the coal samplle from Qipanjing and Queergou and this has little to do with the silica-alumina ratio. The ratio between content of acid respectively alkali oxides can be used to predict ash fusion point within a certain range. From the table it is observed that the silica-alumina ratio for Shanghaimiao coal sample is high and the total content of SiO2 and Al2O3 takes up more than 80% of the ash. Its alkali oxides content is the lowest of all three coal samples and is 8.5% of the total content. In the coal samples from Qipanjing and Queergou, however, the alkali oxides content is very high and the CaO content reaches 4.35% and 9.12% respectively. The melting point of CaO is as high as 2610℃, which is likely the reason why the coal sample has an excessively high ash fusion point. 匆匆，供参考 |
