abstract="The suppression effects of ultrafine Mg (OH)<sub>2</sub> powders with different particle sizes and mass fractions on explosion flame of wood dust are experimentally studied in a half-closed vertical experimental duct. Flame structures and characteristic parameters, including flame light emission images, propagation velocity, temperature, during the flame propagation of wood dust explosion are recorded by high-speed photography and fine thermocouple. Thermal decomposition behaviors of wood dust and Mg(OH)<sub>2</sub> powders are studied using synchronous thermal analyzer. Chemical structures of residual dust samples after the explosion are characterized by Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. The experimental results show that explosion flame of wood dust is obviously suppressed by physical and chemical effects of Mg(OH)<sub>2</sub> powders, and the suppression effect of nano-Mg(OH)<sub>2</sub> is better than that of micron-Mg(OH)<sub>2</sub> under same mass fractions. By analyzing multiple characteristics of nano-powders, the advantages of nano-Mg(OH)<sub>2</sub> over micron-powders are further investigated.<br><br>Copyright © 2019 Elsevier B.V.
