Study on suppression effect and mechanisms of phosphorus-containing recycling substance on flame propagation of methane/coal dust composite explosion

Meikuang Anquan
Magnesium ammonium phosphate (MgNH4PO4·6H2O) is a phosphorus-containing blockage commonly found in sewage treatment pipelines. In order to study its suppression effect on the methane/coal dust composite explosion, magnesium ammonium phosphate was ...

Applications of machine learning to predict and evaluate the explosion of premixed methane- air mixtures

Global warming, caused by the accumulation of greenhouse gases like CO2 and methane, have long-term impact on Earth's climate. Although methane is considered secondary to CO2 in terms of volume, it is considered 29.5 times more potent than CO2 on a 100 ...

Effect of flammable gases produced from coal smoldering on methane explosion limits under nitrogen dilution in coal mines

The methane released from the coal combines with the air to form a very dangerous explosive mixture, which will be aggravated by the combustible gases of CO and H2 produced from the coal smoldering in coal mine.
