Analysis of explosion risk factor potential on coal

2018-10-9  (a) Determine the cause of the explosion factor in a CRT. The risk of explosion in CRT has two main factors, namely internal and external factors. Internal factors come from natural conditions, such as: coal dust, methane gas, spon-taneous combustion propensity, and so forth. External factors are derived from engineering design and confined

Hybrid CH4/coal dust explosions in a 20-L spherical vessel

2019-2-1  Explosion characteristics and influential factors of hybrid CH 4 /coal dust explosions are studied using a 20-L spherical explosion vessel. Experimental results show that the maximum explosion pressure and maximum rate of pressure rise increase in the initial phase and then decrease as the coal dust or CH 4 concentration increases. The optimum concentrations of coal dust and CH 4 are 200 g/m

Explosion characteristics of H2/CH4/air and CH4/coal dust

2012-10-1  Using a standard 20 L explosion spherical vessel, the explosion characteristics of H 2 /CH 4 /air and CH 4 /coal dust/air mixtures as well as the solid explosion products were investigated. Results show that the presence of molecular hydrogen yield from coal spontaneous heated process would significantly increase the maximum explosion pressure and pressure rise rate of H 2 /CH 4 /air mixtures.
