Study of Calculating Model for Minimum Ignition Energy of Dust Clouds

Minimum ignition energy of dust clouds is one of the most important characteristic parameters of dust explosion, it is an important basis for the assessment of electrostatic hazard; It is directly related to the production safety and economic benefits in the process industry. Currently, minimum ignition energy is mainly gained through experiment, and the affecting factors in the process of experimental measurement are sophisticated, different laboratories, different experimental methods or different definition may cause the deviations of the measurement results. In order to reduce the impact of various factors on the results, researchers often summarize a calculating model of minimum ignition energy combined with experimental results. Therefore, on the base of ignition theory of dust clouds, this paper analyzes the estimating calculation formulas of minimum ignition energy that are often used, and provides a reference for the analysis of experimental results.
