The paper presents experimental data on the effect of the initial turbulence of the air suspension flow of aluminum particles on the speed and limits of flame propagation. It was found that when installing the grate, depending on the diameter of the chamber and the size of the aluminum particles, the flame propagation speed can either increase or decrease. In the flow of air suspension of aluminum particles ASD-1, a simultaneous increase in the intensity and scale of turbulence leads to an increase in the flame velocity and expansion of the flame propagation limits.
