Explosion behavior of n-alkane/nitrous oxide mixtures

Abstract

Explosion limitExplosion pressure Burgess-Wheeler law Gas explosion Deflagration index a b s t r a c tThe explosion properties of alkane/nitrous oxide mixtures were investigated and were compared with those of the corresponding alkane/oxygen and alkane/air mixtures. The explosion properties were characterized by three parameters: the explosion limit, explosion pressure, and deflagration index. For the same alkane, the order of the lower explosion limits (LELs) of the mixtures was found to be alkane/oxygen ≈ alkane/air > alkane/nitrous oxide. In addition, the mixtures containing nitrous oxide tended to exhibit higher explosion pressures than the corresponding mixtures containing oxygen under fuel-lean conditions. The Burgess-Wheeler law was also observed to hold for the mixtures containing nitrous oxide.

Flammability limits, explosion pressures, and applicability of Le Chatelier's rule to binary alkane–nitrous oxide mixtures

“…As seen in Figs. 6 and (Koshiba et al, 2015), together with their flammability limits reported in the literature (Shebeko et al, 2013, Pfahl et al, 2000. .0 vol% and 2.0 vol% of LFL for a CH 4 -N 2 O mixture, respectively.…”

“…Fig. 1 illustrates the experimental apparatus, which is identical to that used for a previous study (Koshiba et al, 2015). The closed, cylindrical stainless-steel vessel with a diameter of 100 mm and a height of 120 mm includes a fan for stirring, two tungsten electrodes ( 1.0 mm) for ignition, and two pressure transducers.…”

Turbulent explosion characteristics of stoichiometric syngas

“…2 Therefore, the knowledge about explosion characteristics of syngas is essential to both the optimization design on syngas-fuelled applications and the safety protection strategies on storage and delivery of syngas. 9 However, the research works about explosion characteristics of syngas are very scarce in current literatures, and the reported information about explosion parameters are relative limited. 9 However, the research works about explosion characteristics of syngas are very scarce in current literatures, and the reported information about explosion parameters are relative limited.…”

“…Albeit the fundamental research works about explosion characteristics have been excessively experimentally performed in the past decade, most of those works were conducted on hydrocarbon fuels, such as n-pentane, 3 propylene, 4 methane, 5 methyl ether, 6 nitromethane, 7 ethylene, 8 and n-alkane. 9 However, the research works about explosion characteristics of syngas are very scarce in current literatures, and the reported information about explosion parameters are relative limited. Such lacks are mainly attributed to 2 reasons: (a) compared to hydrocarbon fuels, the value of syngas in utilization abstracts attentions latter; and (b) different to those fuels have specific components, syngas has varieties in the detailed components for different sources and/ or different synthesis technologies.…”

Explosion Behaviour of 30% Hydrogen/70% Methane-Blended Fuels in a Weak Turbulent Environment

“…In the past decade, some scholars contributed into the research about explosion characteristics of blended fuels, including blended fuels of pentane, hexane, and benzene [4], blended fuels of methane and carbon dioxide [5], blended fuels of liquefied petroleum gas [6], blended fuels of hydrogen and nitrogen oxides [7], the blended fuels of hydrogen and dust [8], the blended fuels of natural gas, argon, and nitrogen gas [9], blended fuels of n-alkane and nitrous oxide [10], blended fuels of butanol and octane [11], hydrogen/carbon monoxide blended fuels [12], blended fuels of hydrogen and methane [13]. As could 2 of 15 be seen, the works on the explosion characteristics of hydrogen/methane-blended fuels are relative new and scarce in the current literature.…”
