This paper focuses on the measurement of the minimum ignition energy (MIE) of methane-air and hydrogen-air mixtures at temperatures, down to 200 K.

The lowest ignition energies observed for methane-air mixtures and hydrogen-air mixtures agree reasonably well with the previously reported data.

MIE typically range from 1 mJ to 1000 mJ [Janes]. The lower the MIE, the higher is the risk of explosion as a very small energy input can trigger a dust cloud ...

MIE depends on type of gas and concentration · 8.0% volume methane is "sweet spot" for stoichiometric combustion of methane · Although flammability range for CH4 ...

6 июл. 2016 г. · MIE is the minimum energy to successfully ignite a combustible mixture, and is the key parameter which can be used to evaluate the explosion ...

15 апр. 2011 г. · The minimum ignition energies of the methane/air mixture (all with 8.5% methane) decrease from 6.8 mJ to 0.4 mJ as the spark durations increase ...

It was observed that the probability of ignition increased with increasing energy of the source and that the rate of rise in probability was steepest for the ...

The minimum ignition energies thus determined for methane (0.31 ± 0.01 mj) and propane (0.24 ± 0.01 mj) correspond with published values. Minimum ignition ...

In this study, the dependence of minimum ignition energies (MIE) on ignition geometry, ignition source radius and mixture composition is investigated ...

The minimum ignition energy is the threshold amount of energy or heat that, when applied instantaneously to a small volume of a gas mixture, initiates ...
