Abstract:
In the new coal chemical industry, the prevention and control of coal dust explosion is particularly important. Based on the analysis of the conditions and influencing factors of coal dust explosion, the explosion characteristics such as explosion concentration, maximum explosion pressure, maximum pressure rise rate and limit oxygen content of pulverized coal were tested based on the 20 L dust explosion characteristic test system. The experimental results provide important theoretical basis for coal-to-oil enterprises to take effective safety and technical measures.
