The upper explosion limit of lower alkanes and alkenes in air at elevated pressures and temperatures

Auto-ignition and upper explosion limit of rich propane–air mixtures at elevated pressures

“…However, near the autoignition area a deviation from the linear temperature dependence is observed. This was also observed in a previous study by Van den Schoor and Verplaetsen [11], who attributed this deviation to the proximity of the auto-ignition area. The results of this study corroborate this idea.…”

“…Fig. 9 compares the measured upper explosion limits of this study with previous flammability experiments performed by Van den Schoor and Verplaetsen [11]. There is a good agreement between both UEL data.…”

“…9. Comparison of UEL data of propane-air mixtures obtained in this study and from Van den Schoor and Verplaetsen [11].…”

“…There is a good agreement between both UEL data. The differences in set-up of both series of experiments are firstly the volume of the vessel: 8 l instead of 4.2 l, and secondly the pressure rise criterion: a relative pressure rise of 5% instead of 1% for the data of [11]. It can be seen that for high temperatures the upper explosion limit determined with the 5% pressure rise criterion is lower than with the more conservative 1% pressure rise criterion as was expected.…”

Comparison and evaluation of methods for the determination of flammability limits, applied to methane/hydrogen/air mixtures

“…Further details about the experimental set-up and procedure can be found elsewhere [11]. All experiments are performed at an initial pressure of 102 ± 1 kPa and an initial temperature of 295 ± 3 K.…”
