摘要
为了提高洗混煤低位发热量定量分析的精度,针对当前洗混煤低位发热中间介质的换热效率计算可靠性不高的问题,提出了基于多元线性回归分析法的洗混煤低位发热量数学模型。结果表明,该数学模型能准确定量计算洗混煤低位发热和传热的温度分布和传热系数分布状态,对发热量的变化规律拟合准确度高。
In order to improve the calorific value of mixed coal washing of quantitative low precision for the current to wash mixed heat efficiency of coal low heating medium calculation reliability problems,based on the multiple linear regression mixed coal washing and low calorific value of mathematical model analysis method. The results show that the mathematical model can accurately calculate the amount of wash mixed distribution and heat transfer the distribution of temperature coefficient of coal low heating and heat transfer of heat, the change rule of high fitting accuracy.
