THERMODYNAMICS OF THE COAL DUST EXPLOSION: MAIN FACTORS AND OPTIMAL CONTROL

ABSTRACT
The explosion intensity and the low explosion limit of the coal dust explosion are affected by the calorific value and the heat transfer rate of the coal dust, which are closely related to the coal quality index. This paper studies experimentally the low explosive limit of the coal dust with different coal quality indexes. Based on the principal component analysis, the main factors affecting the low explosive limit are obtained by extracting the principal components from the coal quality indexes. Through comparative analysis, a regression model is proposed to predict the low explosive limit for practical applications.
