Physical and mathematical modeling of high-temperature heat and mass transfer and kinetics of chemical transformations of a two-fraction gas suspension of carbon particles is carried out. The characteristics of ignition and combustion of gas-suspension particles in air at different gas temperatures are determined. With a decrease in the gas temperature, the induction period of the fine fraction exceeds the induction period of the coarse fraction, and the burning temperature is lower. Critical parameters of ignition and extinction of a two-fraction gas suspension are found.
