Effects of particle size, dust concentration and dust-dispersion-air pressure on rock dust inertant requirement for coal dust explosion suppression in underground coal mines

Chemical Engineering Research and Design, 2019
Coal dust explosion constitutes an ever-present hazard in underground coal mines worldwide. This study examines the effects of important parameters, such as, dust particle size, dust concentration and dust-dispersion-air pressure on rock dust inertant ...

Suppression of wood dust explosion by ultrafine magnesium hydroxide.

Journal of Hazardous Materials, 2019
The suppression effects of ultrafine Mg (OH)2 powders with different particle sizes and mass fractions on explosion flame of wood dust are experimentally studied in a half-closed vertical experimental duct. Flame structures and characteristic parameters,

Suppression of pulverized biomass dust explosion by NaHCO3 and NH4H2PO4

Renewable Energy, 2020
To effectively mitigate accidental biomass dust explosion, the suppression capacities of NaHCO3 and NH4H2PO4 for biomass dust explosion were determined. Suppression mechanism of biomass flame was further revealed.

A study on the FTIR spectra of pre- and post-explosion coal dust to evaluate the effect of functional groups on dust explosion

Chemical Engineering Research and Design, 2019
Fourier transform infrared (FTIR) spectra of coal dust and its explosion solid residues were studied. Coal dust explosion test was carried out on a 20-L explosion device, and the variation of different functional groups and FTIR structural parameters of ...
