利用固相能量守恒定律判定煤炭最短发火期

Applying Solidoid Energy Conservation Law to Determining Shortest Self-ignition Period of Coal

利用固相能量守恒定律判定煤炭最短发火期技术,建立简便实效的数学模型,并与使用TGA/SDTA851 e同步热分析仪所得的数据进行拟合,对煤的实验最短发火期进行测算,大幅提高最短发火期预测的效率和精度,对我国研究煤自燃预测预报和煤炭自燃预防具有重要的参考价值。

Utilizing solidoid energy conservation law,the paper set up a simple and practical mathematic model and fit with data from TGA/SDTA851e synchronous thermal analyzer to calculate shortest self-ignition period of coal.This method shortened largely prediction efficiency and accuracy of shortest self-ignition period,which provided important reference for researching coal self-ignition period prediction and prevention.
