摘要
本文利用计算机编程对湿煤堆非稳态自热过程的一维模型进行差分计算,求得不同煤层厚度湿煤堆内的非稳态温度场。结果表明,采用自热过程的非稳态数学模型计算,可以剖析影响湿煤堆自热的因素。
The paper has obtained a transient temperature distribution in the coal pile using computer programs to solve one-dimensional differential difference equations for the transient self-heating process of the pile. The results indicate that the mathematical model for the transient self-heating process can describe properly the factors affecting the self- heating of coal. They provide a theoretical guidance for evaluating the spontaneous risk of a real stockpile of coal.
