回归分析在中煤灰分与发热量关系分析中的应用

The Application of Regression Analysis in Study of the Relationship between Middling Coal' s Ash Content and Thermal Value

利用太原煤气化公司晋阳选煤厂中煤灰分与发热量的对应数据资料,将中煤灰分与发热量之间的变动关系加以模型化,导出回归方程,从而能够准确快速地预测中煤的发热量并对实测发热量值进行验证审核,对煤质管理具有较好的指导意义。

By using the corresponding data of ash content and thermal value of middling coal in Jinyang Coal Cleaning Plant of Taiyuan Coal Gasification Company,this paper models the changing relations between middling coal＇ s ash content and thermal value,derives the regression equations,being able to accurately and quickly forecast middling coal＇ s thermal value and verify the measured thermal value,and providing excellent guidance for coal quality control.
