In order to promote the optimization and upgrading of metal dust explosion-proof technology and establishment of a safety protection and control system, this study systematically investigated the reaction kinetics of aluminum powder with excess water under varying particle sizes and stacking masses, based on the self-developed visualization experimental platform for the reaction between stacked metal dust and water. Through quantitative characterization of the effects of particle size and stacking mass on key reaction parameters-including the maximum temperature, total gas production, maximum hydrogen concentration, maximum pressure, and total reaction time-the kinetic mechanism of the aluminum-water reaction was revealed. The results demonstrate that at a fixed particle size, all characteristic parameters exhibit positive correlations with increasing stacking mass. At a fixed stacking mass, the maximum temperature follows a V-shaped trend (decreasing then increasing) with increasing particle size, while gas production, hydrogen concentration, and pressure show inverted U-shaped trends (increasing then decreasing). Total reaction time increases monotonically with increasing particle sizes. The primary reaction products are Al(OH)3 and H2, and the reaction process comprises three distinct stages: slow hydrogen evolution, violent reaction, and attenuation and termination.
