TL;DR: In this article, the effects of water vapor addition on the low-concentration coal mine methane combustion in porous media were investigated, and a 2D numerical model based on a two-section ceramic foam burner setup with high flame stability was established and multi-step kinetics mechanisms were imported to the model.

TL;DR: In this paper, a vertical pipeline was built to study the explosion of wheat dust with different particle size distribution under the addition of (NH4)2HPO4, and the characteristics of the wheat dust explosion were recorded by high-speed photography, ion probe and micro-thermocouple.

TL;DR: It is confirmed that APP can delay peak temperature arrival time, weaken temperature fluctuation, and decrease peak values of flame temperature and temperature rising rate, which provides a new solution for prevention and suppression deflagration of dust waste in sugar industry.

TL;DR: In this article, the authors investigated the flame propagation of coal dust deflagration and the inhibition characteristics of coal ash which as a mixed inert powder under the atmosphere of methane, and built a vertical combustion pipe with half-open.

TL;DR: In this article, a vertical combustion pipe was built to conduct the deflagration experiment of coal dust/ABC powder, and the chemical bonds and surface functional groups of the residue were characterized.
