我国商品褐煤低位发热量回归式的推导

Equations of calculating calorific value of lignite in China

在研究褐煤发热量(Qgr,daf)与其元素成分中的碳(Cdaf)和氧(Odaf)以及与工业分析中的挥发分(Vdaf)之间相关关系的基础上,分别推导出了计算不同矿区商品褐煤的Qnet,ar的多元回归式.这些回归式均有较高的计算精度,可为广大用煤企业参照使用.

Based on relations between Q_(gr,daf ) and C_(daf) ,O_(daf),V_(daf), the multivariate regression equations that calculating calorific value (Q_(gr,daf)) of lignite in different coal mines were obtained.These equations have perfect precision and can be widely used for most enterprises.
