Abstract: Using the equivalent data calculated for electric spark obtained from experiment as energy input and according to the ignition mechanism of dust clouds, a mathematical model was developed for the minimum ignition energy of dust clouds. Then, the influence of dust particle size, dust concentration, turbulence, spark energy density and spark discharging time on minimum ignition energy was studied through model calculation. The result was basically consistent with the experiment data, and combining the model calculation with experimental measurement could make the determination of minimum ignition energy of dust clouds more accurate and reasonable.
