EFFECT OF IGNITION ENERGY ON COAL DUST EXPLOSION

ABSTRACT
Coal dust explosion is of great importance for both theoretical analysis and practical applications. However, there is not a complete theory to reveal its mechanism. Here we show that the ignition energy plays an important role. An experiment is designed using different volatile coal dusts under different ignition energies, and the results are extremely helpful for avoiding coal dust explosion and can be also used for verification of a new theory.
KEYWORDS
