Research of minimum ignition energy for nano Titanium powder and nano Iron powder

Abstract Most manufacturing units that process nanoparticles face a threat from fires and explosions. This study examines Ti powders with diameters of 3 μm, 8 μm, 20 μm, 45 μm, 35 nm, 75 nm, and 100 nm, and Fe powders with diameters of 150 μm, 15 nm, 35 nm, and 65 nm. The goal of our study was to measure the minimum ignition energy (MIE) for each of the above mentioned powders using a modified version of the 1.2-L Hartmann apparatus. According to the data obtained from the experimental results, the MIEs for all the nanopowders were less than 1 mJ; the low MIEs of these powders indicate that they are extremely combustible. Therefore, it is imperative for manufacturing units of these powders to take precautionary measures against untoward incidents involving, electrostatic sparks, collisions, etc.
