Statistical analysis of minimum electrostatic spark ignition energy of dust cloud

According to the logistic regression model based on statistical analysis, the experiments on the minimum ignition energy of different concentrations of nicotinic acid dust-air mixtures have been conducted in the Mike 3 tube by the calculation method of the minimum ignition energy of dust cloud which represented by probability, the volume of Mike 3 tube is 1. 28 L. Utilizing SPSS software, the minimum ignition energy of various concentrations of nicotinic acid dust cloud when the ignition probabilities are 10% and 50% has been calculated. The results show that the minimum ignition energy of nicotinic acid dust cloud has a tendency to first decrease and then increase with increasing concentrations, finally maintain at a certain energy range. Compared with other standard calculations, the viewpoint of ignition as a statistical phenomenon appears to be more consistent with the test data in engineering, it can also meet the needs of different production environments for security control.
