On the minimum ignition energy (MIE) for propane/air

Influence of nitromethane concentration on ignition energy and explosion parameters in gaseous nitromethane/air mixtures

“…The average between the energy input in a "failed ignition" and a "successful ignition" is 0.41 mJ which is more close to 0.48 mJ. The experimental results of this work roughly agree with the data reported in [16].…”

“…The chemical character of propane/air is similar to that of gaseous nitromethane/air mixture. The MIE of gaseous nitromethane/air mixture obtained in this work is compared with propane/air reported in [16]. The lowest value of MIE among the values determined for all investigated mixtures in this work is 0.7 mJ which is more than 0.48 mJ for propane/air slightly.…”

“…Eckhoff et al built a copy of the standard ASTM spark generator for determination of MIEs of gases and vapours and obtained a MIE of 0.48 mJ for propane/air [16]. The MIE of the gaseous nitromethane/air mixture is not available in the previous literatures.…”

“…In earlier time, Tricot et al [12,13] studied the reaction of nitromethane with oxygen, and Hsu et al [14] suggested a detailed chemical mechanism describing the ignition of hightemperature gaseous nitromethane. It has been found that the ignition characteristics of flammable gases [15][16][17][18] explosion performances [19,20] bear close relationship with their concentrations. Although plenty of research achievements have been made in the respect related to the combustion parameters of flammable gases and their MIEs, unfortunately, fewer researchers have paid attention to the behavior of combustion for mixtures of pure nitromethane and air.…”

Flammability limits: A review with emphasis on ethanol for aeronautical applications and description of the experimental procedure

“…Many papers have been published about ignition [58][59][60][61][62][63]. It should be noted that experiments on ignition energies carried out by Pasamehmetoglu and Unal [64] …”
