Effects of particle size distribution on the explosion severity of coal dust

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2019
The effects of particle size distribution (PSD) on coal dust explosion severity were investigated using a 20 L vessel. The severity was evaluated by the maximum explosion pressure (Pex), the maximum rate of pressure rise ((dP/dt)ex), and the time spans (t1, t2) between ignition and Pex and between ignition and (dP/dt)ex during a trial. These parameters

Numerical Simulation of the Tar Mist and Dust Movement Process in a Low-Temperature Dry Distillation Furnace

Journal of Chemistry, 2020
In the low-temperature dry distillation of low-rank coal, the important liquid product of coal tar is produced, but its quality and utilization rate are degraded by entrained dust.

ACE-ASIA - Regional climatic and atmospheric chemical effects of Asian dust and pollution [PDF]

, 2004
Although continental-scale plumes of Asian dust and pollution reduce the amount of solar radiation reaching the earth's surface and perturb the chemistry of the atmosphere, our ability to quantify these effects has been limited by a lack of critical ...

The dependence of particle size on cell toxicity for modern mining dust

Scientific Reports, 2023
Progressive massive pulmonary fibrosis among coal miners has unexpectedly increased. It would likely due to the greater generation of smaller rock and coal particles produced by powerful equipment used in modern mines.
