The flammability limit is a key parameter for assessing the combustion and explosion hazards of flammable gases,holding fundamental importance in industrial safety sectors such as chemical engineering,en-ergy,and mining.To enable effective prevention and control of flammable gas accidents,this paper systemati-cally reviewed prediction methods for the flammability limits of both single-component and multi-component mix-tures.It focused on analyzing classical theoretical models-including the heat of combustion method,stoichiomet-ric concentration method,Larry's formula,Le Chatelier's formula,and adiabatic flame temperature method.This study compared their applicable ranges and prediction deviations,and discussed models suited for harsh conditions such as high temperatures and high pressures.The results indicated that classical theoretical models achieved high accuracy in predicting the lower flammability limits of hydrocarbons under normal temperature and pressure.However,under high-temperature and high-pressure conditions,existing prediction models were pri-marily empirical or semi-empirical correlations derived from experimental data,which generally suffered from in-sufficient prediction accuracy and weak generalization capability.Based on these findings,future research should aim to develop advanced models incorporating multi-physics and multi-scale coupling,vigorously promote innovation in artificial intelligence-driven intelligent prediction methods,and achieve key breakthroughs in safe-ty assessment technologies for emerging energy systems.These efforts will contribute to refining the theory of combustion and explosion and provide substantial support for enhancing industrial safety protection levels.
