Abstract

Abstract

In order to evaluate the explosion sensitivity of corn starch dust cloud accurately, to carry out the dust explosion-proof work effectively, and to ensure safe production of grain industry, a series of experiments were performed by using a standard Godbert-Greenwald constant temperature oven device to explore the influence laws of the following factors on the minimum ignition temperature of corn starch dust cloud. These influencing factors include dust concentration, diffusing pressure, the mass fraction of CaCO₃, and their interactions. The sensitivities of the minimum ignition temperature of corn starch dust cloud to these influencing factors were investigated on the basis of the interactive orthogonal design method. And the results are close through both the range analysis and the analysis of variance. The mass fraction of CaCO₃ and the dust concentration have highly significant effects on the minimum ignition temperature of maize starch cloud. The interaction between the spraying pressure and the dust concentration has significant effects on the minimum ignition temperature of maize starch cloud.
