摘要
Abstract
Dust of Chinese parasol was used as an additive agent of industrial powder explosives to study its explo-sion characteristics. Hartmann tube was used in testing the minimum ignition energy of dust cloud, and the values of Sam-ple 1#, Sample 2# and Sample 3# were confirmed as 70 mJ, 90 mJ, and 150 mJ respectively. Box-Behnken experimental design of response surface methodology was applied to measure the dust explosion pressure by using 20 L spherical test device. Regression equation was fitted from experimental results. It is concluded that dust concentration has the greatest influence on explosion pressure, followed by ignition energy and dust particle size. Experimental conditions of explosion pressure were optimized and tested to be 0. 7959 MPa. Error between the experimental and predicted values is only 1. 28%, which shows the feasibility of this model.关键词
