  The results of an experimental study of the combustion of aluminum particles in N2/O2 gas mixtures are presented and interpreted. This research focuses on measurement of flame speed and combustion velocity in aluminum particle dust cloud combustion. The dust dispersion technique uses an annular high-speed jet which disperses dust continuously supplied via a piston-type dust feeding system. Particles of one initial diameters of 18 micron were studied in this experiment. Flame speed as a function of dust concentration was determined during the laminar stage of flame propagation in dust-oxygen-nitrogen mixtures . It was found that increasing in O2 part (21% O2 to 25% O2) in N2/O2 gas mixtures leads to increasing in combustion velocity.
