To investigate the relationship between flow temperature (FT) and the temperature that corresponds to different liquid phase mass fractions, the FTs of 10 coal ashes and 45 synthetic ashes were tested by an ash-fusion-temperature analyzer. The linear correlation between the FT and the temperature that corresponded to a 90% liquid phase (T₉₀) calculated by FactSage was: FT = 245.837 + 0.765T₉₀, and its correlation coefficients was 0.91. This model may be more accurate for low Si/Al coal. The differences between measured and predicted FT based on the model were in the measuring error range.

FactSage基于液相质量分数预测灰分流温度

为了研究流动温度（FT）和对应于不同液相质量分数的温度之间的关系，使用灰融温度分析仪测试了10种煤灰和45种合成灰的FT。FactSage计算得出的FT与温度（对应于90％液相（T ₉₀））之间的线性相关为：FT = 245.837 + 0.765T ₉₀，并且其相关系数为0.91。对于低Si / Al煤，此模型可能更准确。基于模型的实测FT与预测FT之间的差异在测量误差范围内。
