Study of Parameters and Theory of Sucrose Dust Explosion

To investigate the parameters of sucrose dust explosion, minimum ignition energy (MIE) and temperature (MIT) were evaluated. The experiments tested MIE under different conditions quantity, delay time (IDT), powder injection pressure (PIP). MIT particle sizes. results demonstrate that three was an open-up quadratic polynomial. When IDT, PIP 0.5 g (417 g/m3), 90 ms, 150 kPa, respectively, 58.9 mJ, 62.6 52.4 mJ. positively correlated with size dust, 340 °C. At molecular level, “O–H” bonds molecule hydroxyl groups broken by discharge electrodes or high to generate H2. combustion H2 caused explosion spread surrounding made deposited rise, forming interlocking explosion. would not stop until concentration dropped below lowest limit. this study can provide guidance for enterprises prevent accidents.
