Experimental investigations on the roles of moisture in coal dust explosion
TL;DR: In this article, the role of moisture in coal dust explosion was investigated, and it was found that limiting the moisture content is necessary when measuring explosion parameters in practice, and that (dp/dt)ex is more sensitive than Pex and MEC to the particle agglomeration.

Explosibility of hydrogen–graphite dust hybrid mixtures
TL;DR: In this article, the authors evaluated the hazard of combined hydrogen/dust explosions under severe accident conditions in International Thermonuclear Experimental Reactor (ITER), using a standard method of 20-L-sphere to measure the explosion indices of 4-μm fine graphite dust.

Dust explosion hazard in ITER : Explosion indices of fine graphite and tungsten dusts and their mixtures
A. Denkevits,S. Dorofeev +1 more
TL;DR: In this article, the effect of graphite particle size on the explosion performance of tungsten and graphite dust in the range 4-45μm was studied. But the results showed that the graphite particles had a profound effect on their explosion characteristics, including maximum overpressure and rate of pressure rise.
