Analytical expressions for calculating the maximum undercritical heating up and critical conditions of dust fuel ignition. For the first time it was experimentally revealed the possibility of "double flash" for bituminous coal dusts in conditions close to critical. Analytical expressions for calculating the normal flame velocity in solid fuel dust was obtained for the first time. The ratio of conductive and radiation heat transfer in the flame was analyzed according to parameters of dust. It was demonstrated and explained that when a flame propogates upwards sedimentation of fuel particles significantly affects the magnitude of the normal velocity of flame propagation.
