Effects of Ammonia Substitution on Explosion Limits of Methane
Journal of Ammonia Energy, 2023 As a hydrogen-rich and carbon-free fuel, ammonia is regarded as a promising carrier and storage medium for clean energy. By mixing methane with ammonia, the emission of carbon dioxide is also significantly reduced, which is of great significance for reducing greenhouse gas emissions and protecting the environment.

Spectrographic studies of the explosive combustion of methane [PDF]
Proceedings of the Royal Society of London. Series A - Mathematical and Physical Sciences, 1937 Abstract The combustion of the simpler hydrocarbons has been studied over a wide range of conditions and many analytical and kinetic data have been accumulated. Although several spectroscopic investigations have been made, all have been confined within narrow experimental limits and none accompanied by detailed chemical analyses.

Active explosion barrier performance against methane and coal dust explosions [PDF]
International Journal of Coal Science & Technology, 2015 Preventing the propagation of methane or coal dust explosions through the use of active explosion-suppression systems remains one of the most underutilised explosion controls in underground coal mines. As part of the effort to develop better technologies to safeguard mines, the use of active barrier systems was investigated at Kloppersbos in South ...
