热爆炸理论在硝酸铵水溶液热安全性研究中的应用

Application of Thermal Explosion Theory to the Study on the Thermal Safety of Ammonium Nitrate Solution

本文概述了均温系统热爆炸非稳定理论,将其应用于含不同量杂质的硝酸铵水溶液体系中,并将临界爆炸温度和爆炸延滞期的试验值与计算值进行比较,结果表明应用热爆炸理论预先估算硝酸铵水溶液体系中达到任意升温的时间和预先计算达到预先选择的对应于爆炸的升温所需要的时间是可行的。

This paper briefly introduces the thermal explosion unstable theory of uniform temperature system and applies it into the study of ammonium nitrate solution with impurities.The experimental values and calculated values of critical temperature and times-to-ignition are compared and the results indicate that it is feasible to estimate the time to reach any warming time and pre-calculate the time needed to reach the preselected warming that corresponds to the explosion.
