Summary:Title screen
A numerical study of the low-temperature (less than 500 K) ignition of a single coal particle within the framework of a model taking into account the interrelated processes of heat transfer in the particle and the surrounding gaseous medium, thermal decomposition of the coal, diffusion of decomposition products (volatiles) and their oxidation, heating of the coke residue (carbon), and heterogeneous ignition is carried out. The integral characteristic (delay time) of the low-temperature gas-phase ignition of the products of the thermal decomposition of 50- to 500-μm coal particles are determined. The minimum temperature of the air medium at which the ignition of the volatiles occurs and the lowest surface temperature of the particle at which its heterogeneous ignition after the burnout of the volatiles occurs are evaluated.
