| 摘 要： | 依据172组商业用煤分析数据,对7种经验公式的准确性和适用性进行了检测;在此基础上,进一步对煤灰酸碱比与ST和FT关系进行了分析,采用分段拟合的方法,推导出利用煤灰酸碱比计算ST和FT的一组关系式,预测结果与实测值具有较好的一致性,且关系式适用范围较广,可对实际工作起到指导作用。

| Abstract: | Based on the analytical datas of 172 types of China commercial coal samples,the accuracy and applicability of seven empirical formulars for predicting the coal ash FT is analyzed.On this basis,the relationship between acid/alkali ratio and ST,FT is further analyzed.With sectional fitting method,a group of polynomial regression equations which can be used to calculate ST and FT are gained,and the experimental results tally with the prediction.The results have certain reference value in practical work. |
