Potential Risk Evaluation of Thermal Explosion for Exothermic Reaction System

This paper discussed the thermal equilibrium and critical condition in exothermic reaction system, and deduced the values of dynamic parameters such as the judging criterion for thermal runaway, the ignition temperature and extinction temperature in the critical state of thermal runaway when there is no consumption of reaction materials. Then an approach was put forward to evaluate the potential risk of thermal runaway in exothermic reaction system by use of system safety index, and the equilibrium region of exothermic reaction systems was analyzed. Finally, paper takes the decomposing explosion of methyl nitrate as an example to illustrate how to use this approach to quantitatively evaluate the potential dangers in such exothermic reaction system with possibility of thermal explosion.
