“…They also confirmed that the CFT model predicts the lower flammability limit of steam-containing hydrogen mixtures from the thermal emissivity near the limit. 202 The chemical kinetics of hydrocarbon combustion plays a vital role in the UFL in the air. 159,203 Therefore, it is difficult to accurately calculate the heat of the reaction without involving chemical kinetics or chemical equilibrium in the modeling process.…”

“…The heat loss is estimated using the CFT coefficient, which improves the calculation accuracy of the lower flammability limit of the mixed gas at high temperatures. They also confirmed that the CFT model predicts the lower flammability limit of steam-containing hydrogen mixtures from the thermal emissivity near the limit. Kim et al proposed an improved prediction model for the combustion hazard of hydrogen/carbon monoxide using a computational flame temperature model considering heat loss.…”

The flammability limits are essential parameters that reflect the risk of a gas explosion and are affected by the temperature, pressure, and inert gas. Many industrial processes are run at high temperatures and high pressures. Incidents involving combustible gas explosions are frequent; however, issues with gas explosion safety at high temperatures and pressures are never addressed. There have been no substantial advances in theoretical prediction for a long time and a dearth of perfect theories and systematic data collection. Many factors, such as thermal decomposition and slow oxidation, need to be considered at high temperatures and high pressures, which causes difficulties in measurements and inadvertently increases the potential explosion risk. This paper reviews the historical experimental research on the flammability limit of combustible gases at elevated temperatures and pressures and the prediction model of flammable limits by examining the influence mechanism of high temperatures and high pressures. An overview of the theory of flammability limits, criterion of flammability limits, experimental studies, and current status of flammability limit prediction models for combustible gases at high temperatures and pressures are highlighted to help establish and improve the accuracy of flammability limit prediction models at high temperatures and pressures.
